Prevent the keyboard from displaying on activity start

问题

I have an activity with an Edit Text input. When the activity is initialized, the Android keyboard is shown. How can the keyboard remain hidden until the user focuses the input?

回答1:

I think the following may work

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

I've used it for this sort of thing before.

回答2:

Try this also -

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

Otherwise, declare in your manifest file's activity -

<application android:icon="@drawable/icon" android:label="@string/app_name">
<activity android:name=".Main"
          android:label="@string/app_name"
          android:windowSoftInputMode="stateHidden"
          >

If you have already been using android:windowSoftInputMode for a value like adjustResize or adjustPan, you can combine two values like:

<activity
        ...
        android:windowSoftInputMode="stateHidden|adjustPan"
        ...
        >

This will hide the keyboard whenever appropriate, but pan the activity view in case the keyboard has to be shown.

回答3:

Hide it for all activities using the theme

<style name="MyTheme" parent="Theme">
    <item name="android:windowSoftInputMode">stateHidden</item>
</style>

set the theme

<application android:theme="@style/MyTheme">

回答4:

Add these two properties to your parent layout (ex: Linear Layout, Relative Layout)

android:focusable="false"
android:focusableInTouchMode="false"

It will do the trick :)

回答5:

Try to declare it in menifest file

<activity android:name=".HomeActivity"
      android:label="@string/app_name"
      android:windowSoftInputMode="stateAlwaysHidden"
      >

回答6:

If you are using API level 21, you can use editText.setShowSoftInputOnFocus(false);

回答7:

Just Add in AndroidManifest.xml

<activity android:name=".HomeActivity"  android:windowSoftInputMode="stateHidden">
</activity>

回答8:

You can also write these lines of code in the direct parent layout of the .xml layout file in which you have the "problem":

android:focusable="true"
android:focusableInTouchMode="true"

For example:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    ...
    android:focusable="true"
    android:focusableInTouchMode="true" >

    <EditText
        android:id="@+id/myEditText"
        ...
        android:hint="@string/write_here" />

    <Button
        android:id="@+id/button_ok"
        ...
        android:text="@string/ok" />
</LinearLayout>

EDIT :

Example if the EditText is contained in another layout:

<?xml version="1.0" encoding="utf-8"?>
<ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    ... >                                            <!--not here-->

    ...    <!--other elements-->

    <LinearLayout
        android:id="@+id/theDirectParent"
        ...
        android:focusable="true"
        android:focusableInTouchMode="true" >        <!--here-->

        <EditText
            android:id="@+id/myEditText"
            ...
            android:hint="@string/write_here" />

        <Button
            android:id="@+id/button_ok"
            ...
            android:text="@string/ok" />
    </LinearLayout>

</ConstraintLayout>

The key is to make sure that the EditText is not directly focusable.
Bye! ;-)

Best solution for me, paste your class

@Override
public void onResume() {
    this.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
    super.onResume();
}

@Override
public void onStart() {
    this.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
    super.onStart();
}

回答10:

Just add this in your manifest.xml file

<activity android:name=".MainActivity"
            android:windowSoftInputMode="stateHidden">

You are all done.

回答11:

Function to hide the keyboard.

public static void hideKeyboard(Activity activity) {
    View view = activity.getCurrentFocus();

    if (view != null) {
        InputMethodManager inputManager = (InputMethodManager) activity.getSystemService(Context.INPUT_METHOD_SERVICE);

        inputManager.hideSoftInputFromWindow(view.getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);
    }
}

Hide keyboard in AndroidManifext.xml file.

<activity
    android:name=".MainActivity"
    android:label="@string/app_name"
    android:theme="@style/AppTheme"
    android:windowSoftInputMode="stateHidden">

回答12:

To expand upon the accepted answer by @Lucas:

Call this from your activity in one of the early life cycle events:

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

Kotlin Example:

override fun onResume() {
  super.onResume()

  window.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN)
}

回答13:

You can try this set unique attribute for each element

TextView mtextView = findViewById(R.id.myTextView);
mtextView.setShowSoftInputOnFocus(false);

Keyboard will not show while element is focus

回答14:

//to hide the soft keyboard
InputMethodManager imm = (InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(v.getWindowToken(), 0);

回答15:

just add this on your Activity:

@Override
public boolean dispatchTouchEvent(MotionEvent ev) {
      if (getCurrentFocus() != null) {
           InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
           imm.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), 0);
      }
      return super.dispatchTouchEvent(ev);
}
