How to Trigger the soft keyboard?

问题

How can I trigger the software keyboard and add listeners to it's keys?

回答1:

To display the soft keyboard you might try: InputMethodManager.showSoftInput()

As for adding listeners, the best you can do is add a TextChangedListener to an EditText to listen to the changes in the EditText view that are made via the keyboard.

Ive tried two options, but none of them worked in the emulator, as i said, i am trying to pop up soft keyboard on long-press menu:

@Override

public boolean onKeyLongPress(int keyCode, KeyEvent event)

{

            if (keyCode == KeyEvent.KEYCODE_MENU)
        {
             showSoftInput.getInputMethodList();
             showSoftInput.toggleSoftInput(showSoftInput.SHOW_FORCED, 0);

            return true;
        }
        return super.onKeyLongPress(keyCode, event);
    }

second option:

View.OnLongClickListener mLongClickListener = new View.OnLongClickListener()
    {

        @Override
        public boolean onLongClick(View v)
        {

            Configuration config = RouteMapActivity.this.getResources()
                    .getConfiguration();
            if (config.hardKeyboardHidden == Configuration.HARDKEYBOARDHIDDEN_YES)
            {
                InputMethodManager imm = (InputMethodManager) RouteMapActivity.this
                        .getSystemService(Context.INPUT_METHOD_SERVICE);
                imm.showSoftInput(mapView, InputMethodManager.SHOW_IMPLICIT); // .SHOW_FORCED);
            }
            return false;
        }

    };

You can do this from your`s AndroidManifest.xml by adding

<activity
    android:windowSoftInputMode="stateVisible" ... >
    ...
</activity>

But note: If the user's device has an attached hardware keyboard, the soft input method does not appear. http://developer.android.com/training/keyboard-input/visibility.html
