问题描述:

Which event triggers when we hide / show the keyboard at the android in Javascript? How can I subscribe? I need to show my block after the keyboard completely hides.

网友答案:

It's this thing I found here:

@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
    final int proposedheight = MeasureSpec.getSize(heightMeasureSpec);
    final int actualHeight = getHeight();

    if (actualHeight > proposedheight){
        // Keyboard is shown
    } else {
        // Keyboard is hidden
    }

    super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}

Or you can use the method from here:

@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);


    // Checks whether a hardware keyboard is available
    if (newConfig.hardKeyboardHidden == Configuration.HARDKEYBOARDHIDDEN_NO) {
        Toast.makeText(this, "keyboard visible", Toast.LENGTH_SHORT).show();
    } else if (newConfig.hardKeyboardHidden == Configuration.HARDKEYBOARDHIDDEN_YES) {
        Toast.makeText(this, "keyboard hidden", Toast.LENGTH_SHORT).show();
    }
}
