KeyboardChangeListener
simple and powerful Keyboard show/hidden change listener,without having to add a layout and can run in every Activity;
useage
make activity:
android:windowSoftInputMode="adjustResize"
java:
new KeyboardChangeListener(this).setKeyBoardListener(new KeyboardChangeListener.KeyBoardListener() {
@Override
public void onKeyboardChange(boolean isShow, int keyboardHeight) {
Log.d(TAG, "isShow = [" + isShow + "], keyboardHeight = [" + keyboardHeight + "]");
}
});
