How to show soft-keyboard when edittext is focused

由 人走茶凉 提交于 2019-11-26 03:20:05

问题


I want to automatically show the soft-keyboard when an EditText is focused (if the device does not have a physical keyboard) and I have two problems:

  1. When my Activity is displayed, my EditText is focused but the keyboard is not displayed, I need to click again on it to show the keyboard (it should be displayed when my Activity is displayed).

  2. And when I click done on the keyboard, the keyboard is dissmissed but the EditText stays focused and y don\'t want (because my edit is done).

To resume, my problem is to have something more like on the iPhone: which keep the keyboard sync with my EditText state (focused / not focused) and of course does not present a soft-keyboard if there is a physical one.

To force the soft keyboard to appear, you can use

EditText yourEditText= (EditText) findViewById(R.id.yourEditText);
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.showSoftInput(yourEditText, InputMethodManager.SHOW_IMPLICIT);

And for removing the focus on EditText, sadly you need to have a dummy View to grab focus.

I hope this helps

To close it you can use

InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(yourEditText.getWindowToken(), 0);

This works for using it in a dialog

public void showKeyboard(){
    InputMethodManager inputMethodManager = (InputMethodManager) context.getSystemService(Context.INPUT_METHOD_SERVICE);
    inputMethodManager.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);
}

public void closeKeyboard(){
    InputMethodManager inputMethodManager = (InputMethodManager) context.getSystemService(Context.INPUT_METHOD_SERVICE);
    inputMethodManager.toggleSoftInput(InputMethodManager.HIDE_IMPLICIT_ONLY, 0);
}

I had the same problem. Immediately after editText VISIBILITY change from GONE to VISIBLE, I had to set the focus and display the soft keyboard. I achieved this using the following code:

new Handler().postDelayed(new Runnable() {

    public void run() {
//        ((EditText) findViewById(R.id.et_find)).requestFocus();
//              
        EditText yourEditText= (EditText) findViewById(R.id.et_find);
//        InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
//        imm.showSoftInput(yourEditText, InputMethodManager.SHOW_IMPLICIT);

        yourEditText.dispatchTouchEvent(MotionEvent.obtain(SystemClock.uptimeMillis(), SystemClock.uptimeMillis(), MotionEvent.ACTION_DOWN , 0, 0, 0));
        yourEditText.dispatchTouchEvent(MotionEvent.obtain(SystemClock.uptimeMillis(), SystemClock.uptimeMillis(), MotionEvent.ACTION_UP , 0, 0, 0));                           
    }
}, 200);

It works for me with 100ms delay, but failed without any delay or with only a delay of 1ms.

Commented part of code shows another approach, which works only on some devices. I tested on OS versions 2.2 (emulator), 2.2.1 (real device) and 1.6 (emulator).

This approach saved me a lot of pain.




回答3:


To cause the keyboard to appear, use

getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE);

This method is more reliable than invoking the InputMethodManager directly.

To close it, use

getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN);



回答4:


When nothing else works, force it to be shown:

editText.requestFocus();
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, InputMethodManager.HIDE_IMPLICIT_ONLY);

The following code is pillaged from the Google's 4.1 source code for SearchView. Seems to work, fine on lesser versions of Android as well.

private Runnable mShowImeRunnable = new Runnable() {
    public void run() {
        InputMethodManager imm = (InputMethodManager) getContext()
                .getSystemService(Context.INPUT_METHOD_SERVICE);

        if (imm != null) {
            imm.showSoftInput(editText, 0);
        }
    }
};

private void setImeVisibility(final boolean visible) {
    if (visible) {
        post(mShowImeRunnable);
    } else {
        removeCallbacks(mShowImeRunnable);
        InputMethodManager imm = (InputMethodManager) getContext()
                .getSystemService(Context.INPUT_METHOD_SERVICE);

        if (imm != null) {
            imm.hideSoftInputFromWindow(getWindowToken(), 0);
        }
    }
}

Then in addition, the following code needs to be added as the Control/Activity is created. (In my case it's a composite control, rather than an activity).

this.editText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
    public void onFocusChange(View v, boolean hasFocus) {
        setImeVisibility(hasFocus);
    }
});



回答6:


android:windowSoftInputMode="stateAlwaysVisible" -> in manifest File.

edittext.requestFocus(); -> in code.

This will open soft keyboard on which edit-text has request focus as activity appears.




回答7:


I have had some recent luck in some simple cases with the code below. I haven't finished all testing but....

EditText input = (EditText) findViewById(R.id.Input);
input.requestFocus();    
input.dispatchTouchEvent(MotionEvent.obtain(SystemClock.uptimeMillis(), SystemClock.uptimeMillis(), MotionEvent.ACTION_DOWN , 0, 0, 0));
input.dispatchTouchEvent(MotionEvent.obtain(SystemClock.uptimeMillis(), SystemClock.uptimeMillis(), MotionEvent.ACTION_UP , 0, 0, 0));

And presto the keyboard shows up.




回答8:


You can try to force the soft keyboard to appear, it works for me:

...
dialog.show();
input.requestFocus();
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);

Sometimes raukodraug's answer won't work. I've make it in this way with some trials and errors:

public static void showKeyboard(Activity activity) {
    if (activity != null) {
        activity.getWindow()
                .setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);
    }
}

public static void hideKeyboard(Activity activity) {
    if (activity != null) {
        activity.getWindow()
                .setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
    }
}

And the EditText part: 

    editText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
        @Override
        public void onFocusChange(View v, boolean hasFocus) {
            if (!hasFocus) {
                hideKeyboard(getActivity());
            } else {
                showKeyboard(getActivity());
            }
        }
    });



回答10:


To hide keyboard, use this one:

getActivity().getWindow().setSoftInputMode(
    WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);

and to show keyboard:

getActivity().getWindow().setSoftInputMode(
    WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);



回答11:


showSoftInput was not working for me at all.

I figured I needed to set the input mode: (here in the Activity component in the manifest)

android:windowSoftInputMode="stateVisible"



回答12:


For fragment, sure its working:

 displayName = (EditText) view.findViewById(R.id.displayName);
    InputMethodManager imm = (InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
    imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);



回答13:


Believe or not my problem with Soft Keyboard was resolved when I discovered that the Activities animations can disable the Soft Keyboard. When you call the intent with the 

i.setFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);

and 

overridePendingTransition(0, 0);

It can hide the Soft Keyboard and there isn't a way to show it.




回答14:


I had the same problem in various different situations, and the solutions i have found work in some but dont work in others so here is a combine solution that works in most situations i have found:

public static void showVirtualKeyboard(Context context, final View view) {
    if (context != null) {
        final InputMethodManager imm =  (InputMethodManager) context.getSystemService(Context.INPUT_METHOD_SERVICE);
        view.clearFocus();

        if(view.isShown()) {
            imm.showSoftInput(view, 0);
            view.requestFocus();
        } else {
            view.addOnAttachStateChangeListener(new View.OnAttachStateChangeListener() {
                @Override
                public void onViewAttachedToWindow(View v) {
                    view.post(new Runnable() {
                        @Override
                        public void run() {
                            view.requestFocus();
                            imm.showSoftInput(view, 0);
                        }
                    });

                    view.removeOnAttachStateChangeListener(this);
                }

                @Override
                public void onViewDetachedFromWindow(View v) {
                    view.removeOnAttachStateChangeListener(this);
                }
            });
        }
    }
}



回答15:


editText.post(new Runnable() {
    @Override
    public void run() {
        InputMethodManager imm = (InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.showSoftInput(editText, InputMethodManager.SHOW_IMPLICIT);
    }
});



回答16:


I combined everything here and for me it works:

public static void showKeyboardWithFocus(View v, Activity a) {
    try {
        v.requestFocus();
        InputMethodManager imm = (InputMethodManager) a.getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.showSoftInput(v, InputMethodManager.SHOW_IMPLICIT);
        a.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE);
    } catch (Exception e) {
        e.printStackTrace();
    }
}



回答17:


And for Kotlin just use this extensions:

fun EditText.showKeyboard() {
    val imm = context.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
    imm.showSoftInput(this, InputMethodManager.SHOW_IMPLICIT)
}

fun EditText.hideKeyboard() {
    val imm = context.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
    imm.hideSoftInputFromWindow(this.windowToken, 0)
}



回答18:


code snippet . . .

public void hideKeyboard(Context activityContext){

    InputMethodManager imm = (InputMethodManager)
            activityContext.getSystemService(Context.INPUT_METHOD_SERVICE);

    //android.R.id.content ( http://stackoverflow.com/a/12887919/2077479 )
    View rootView = ((Activity) activityContext)
            .findViewById(android.R.id.content).getRootView();

    imm.hideSoftInputFromWindow(rootView.getWindowToken(), 0);
}

public void showKeyboard(Context activityContext, final EditText editText){

    final InputMethodManager imm = (InputMethodManager)
            activityContext.getSystemService(Context.INPUT_METHOD_SERVICE);

    if (!editText.hasFocus()) {
        editText.requestFocus();
    }

    editText.post(new Runnable() {
        @Override
        public void run() {
            imm.showSoftInput(editText, InputMethodManager.SHOW_FORCED);
        }
    });
}



回答19:


It worked for me. You can try with this also to show the keyboard:

getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);



回答20:


just add android:windowSoftInputMode="stateHidden" in manifest file...




回答21:


final InputMethodManager keyboard = (InputMethodManager) ctx.getSystemService(Context.INPUT_METHOD_SERVICE);
keyboard.toggleSoftInput(InputMethodManager.SHOW_FORCED,0);



回答22:


Inside your manifest:

android:windowSoftInputMode="stateAlwaysVisible" - initially launched keyboard. android:windowSoftInputMode="stateAlwaysHidden" - initially hidden keyboard.

I like to use also "adjustPan" because when the keyboard launches then the screen auto adjusts.

 <activity
      android:name="YourActivity"
      android:windowSoftInputMode="stateAlwaysHidden|adjustPan"/>



回答23:


Simply add this line in your EditText view:

android:isScrollContainer="true"

and TADA - keyboard began to show up automatically!

I had similar problem and discovered this simple and strange solution.

As already was mentioned here by user3392439, appearance of the keyboard upon focus somehow wierdly connected with presense of the scroll component in the XML file.

Even presence of another EditText view which comprises abovementioned line in same XML makes keyboard appear no matter which one of EditTexts is currently focused.

If you have at least one visible view comprising scroll component in your XML file - keyboard will appear automatically on focus.

If no scroll - then you need to click on EditText to make keyboard appear.




回答24:


All solutions given above (InputMethodManager interaction in OnFocusChangeListener.onFocusChange listener attached to your EditText works fine if you have single edit in the activity.

In my case I have two edits.

 private EditText tvX, tvY;
 protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
 tvX.setOnFocusChangeListener(this);
    tvY.setOnFocusChangeListener(this);

@Override
public void onFocusChange(View v, boolean hasFocus) {       
    InputMethodManager imm =  (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
    if(tvX.hasFocus() || tvY.hasFocus()) {            
        imm.showSoftInput(v, 0);            
    } else {
        imm.hideSoftInputFromWindow(v.getWindowToken(), 0);         
    }       
};

I have observed that onFocusChange is triggered for tvX with hasFocus=true (keyboard shown) but then for tvY with hasFocus=true (keyboard hidden). In the end, no keyboard was visible.

General solution should have correct statement in if "show keyboard if EditText text has focus"




回答25:


In your onResume() section of the Activity you can do call the method bringKeyboard();

 onResume() {
     EditText yourEditText= (EditText) findViewById(R.id.yourEditText);
     bringKeyboard(yourEditText);
 }


  protected boolean bringKeyboard(EditText view) {
    if (view == null) {
        return false;
    }
    try {
      // Depending if edittext has some pre-filled values you can decide whether to bring up soft keyboard or not
        String value = view.getText().toString();
        if (value == null) {
            InputMethodManager imm = (InputMethodManager)context.getSystemService(Context.INPUT_METHOD_SERVICE);
            imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
            return true;
        }
    } catch (Exception e) {
        Log.e(TAG, "decideFocus. Exception", e);
    }
    return false;
  }



回答26:


I discovered a strange behaviour, since in one of my apps, the soft keyboard was automatically showing on entering the activity (there is an editText.requestFocus() in onCreate).

On digging further, I discovered that this was because there is a ScrollView around the layout. If I remove the ScrollView, the behaviour is as described in the original problem statement: only on clicking the already focused editText does the soft keyboard show up.

If it doesn't work for you, try putting in a ScrollView -- it's harmless anyway.




回答27:


I had a similar problem using view animations. So I've put an animation listener to make sure I'd wait for the animation to end before trying to request a keyboard access on the shown edittext.

    bottomUp.setAnimationListener(new Animation.AnimationListener() {
        @Override
        public void onAnimationStart(Animation animation) {
        }

        @Override
        public void onAnimationEnd(Animation animation) {
            if (textToFocus != null) {
                // Position cursor at the end of the text
                textToFocus.setSelection(textToFocus.getText().length());
                // Show keyboard
                InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
                imm.showSoftInput(textToFocus, InputMethodManager.SHOW_IMPLICIT);
            }
        }

        @Override
        public void onAnimationRepeat(Animation animation) {
        }
    });



回答28:


I am agree with raukodraug therefor using in a swithview you must request/clear focus like this : 

    final ViewSwitcher viewSwitcher = (ViewSwitcher) findViewById(R.id.viewSwitcher);
    final View btn = viewSwitcher.findViewById(R.id.address_btn);
    final View title = viewSwitcher.findViewById(R.id.address_value);

    title.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            viewSwitcher.showPrevious();
            btn.requestFocus();
            InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
            imm.showSoftInput(btn, InputMethodManager.SHOW_IMPLICIT);
        }
    });

    // EditText affiche le titre evenement click
    btn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            btn.clearFocus();
            viewSwitcher.showNext();
            InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
            imm.hideSoftInputFromWindow(btn.getWindowToken(), 0);
            // Enregistre l'adresse.
            addAddress(view);
        }
    });

Regards.




回答29:


call requestFocus() method on editText in onCrete() method of activity() and call clearFocus() method on the same editText when click done in keypad.




回答30:


If EditText is inside Recycler or ListView and/or this have disable state use below code.

public static void showKeyboardByFocus(final View view)
    {
        view.requestFocus();

        InputMethodManager keyboard = SystemMaster.getInputMethodManager();
        keyboard.showSoftInput(view, InputMethodManager.SHOW_IMPLICIT);

        Runnable re = new Runnable()
        {
            @Override
            public void run()
            {
                view.setEnabled(true);
                view.requestFocus();
            }
        };

        Handler h = new Handler(Looper.getMainLooper());
        h.postDelayed(re, 360);
    }
