Disable input method of EditText but keep cursor blinking

问题

In my Android application, I want an EditText with android:editable="false" but the cursor blinking. The cursor blinking seems doesn't work after "editable" is set to false.

I just want to use my own Keyboard widget(not the system's soft keyboard), and keep the cursor blinking.

Is there any idea to make that possible?

回答1:

Maybe try leaving out the xml attribute android:editable entirely and then try the following in combination to

keep the cursor blinking and prevent touch events from popping up a native IME(keyboard)..

/*customized edittext class 
* for being typed in by private-to-your-app custom keyboard.
* borrowed from poster at http://stackoverflow.com/questions/4131448/android-how-to-turn-off-ime-for-an-edittext
*/
public class EditTextEx extends EditText {
    public EditTextEx(Context context, AttributeSet attrs) {
        super(context, attrs);
    }
    @Override 
    public boolean onCheckIsTextEditor() {

        return false; //for some reason False leads to cursor never blinking or being visible even if setCursorVisible(true) was called in code.
    }       
}

Step 2 change the above method to say return true;

Step 3 Add another method to above class.

@Override
public boolean isTextSelectable(){
    return true;
}

Step 4 In the other location where the instance of this class has been instantiated and called viewB I added a new touch event handler

    viewB.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View view, MotionEvent event) {
            viewB.setCursorVisible(true);
            return false;
        }
    });

Step 5 Check to make sure XML and or EditText instantiation code declares IME/keyboard type to be 'none'. I didnt confirm relevance, but Im also using the focusable attributes below.

<questionably.maybe.too.longofa.packagename.EditTextEx
    android:id="@+id/editText1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:ems="10"
    android:focusable="true"
    android:focusableInTouchMode="true"
    android:inputType="none">

Sorry for so many xml attributes. My code uses them all, testing in 4.2.1, and has results.

Hope this helps.

回答2:

You can use either the xml attribute

android:cursorVisible="false"

or the java function

setCursorVisible(false).

it will work

Just Adding this method for anyone looking for and answer. I have tried many methods but only this one worked from me.

 public static void disableSoftKeyboard(final EditText v) {
    if (Build.VERSION.SDK_INT >= 11) {
        v.setRawInputType(InputType.TYPE_CLASS_TEXT);
        v.setTextIsSelectable(true);
    } else {
        v.setRawInputType(InputType.TYPE_NULL);
        v.setFocusable(true);
    }
}

I called the following from onCreate(), but this affects all EditTexts.

private void hideKeyboard ()
{
    getWindow ().setSoftInputMode (WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
    getWindow ().setFlags (WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM,
                           WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM);
}
