Android: Error popup on EditText doesn't move down when keyboard goes away

Question

I have an activity that displays a few EditTexts on screen for user input. To be sure the soft keyboard doesn\'t cover my fields when it displays I have set the property

Answer 1

I found the the SOLUTION!

Here is the code:

import android.content.Context;
import android.os.Handler;
import android.support.v7.widget.AppCompatEditText;
import android.util.AttributeSet;
import android.view.KeyEvent;
import android.view.MotionEvent;
import android.view.View;
import android.view.inputmethod.InputMethodManager;

public class EditTextPopUpFixed extends AppCompatEditText {

    private static final int TIME_SLEEP = 500;

    private Context ctx;
    private EditTextListener mListener;
    private int backTimes = 0;

    public EditTextPopUpFixed(Context context) {
        super(context);
        ctx = context;
    }

    public EditTextPopUpFixed(Context context, AttributeSet attrs) {
        super(context, attrs);
        ctx = context;
    }

    public EditTextPopUpFixed(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        ctx = context;
    }

    public void setEditTextListener(EditTextListener lis) {
        mListener = lis;

        this.setOnTouchListener(new OnTouchListener() {
            @Override
            public boolean onTouch(View view, MotionEvent motionEvent) {

                backTimes = 0;
                return false;
            }
        });
    }

    @Override
    public boolean onKeyPreIme(int keyCode, KeyEvent event) {

        if (keyCode == KeyEvent.KEYCODE_BACK)
            backTimes++;

        if (backTimes == 3) {
            backTimes = 0;
            mListener.close();
            return true;
        }

        if (keyCode == KeyEvent.KEYCODE_BACK || keyCode == KeyEvent.KEYCODE_ENTER) {
            InputMethodManager mgr = (InputMethodManager) ctx.getSystemService(Context.INPUT_METHOD_SERVICE);
            if (mgr.isActive()) {
                mgr.hideSoftInputFromWindow(this.getWindowToken(), 0);
                boolean mustRevalidate = getError() != null;
                setError(null);
                if (mListener != null && mustRevalidate) {
                    Handler han = new Handler();
                    han.postDelayed(new Runnable() {
                        @Override
                        public void run() {
                            mListener.revalidateEditText();
                        }
                    }, TIME_SLEEP);
                }
            } else {
                backTimes = 0;
                super.onKeyPreIme(keyCode, event);
            }
            return true;
        }
        return false;
    }

    public interface EditTextListener {
        void revalidateEditText(); //Revalidates the EditText to refresh the Popup (Must revalidate the EditText in its implementation)

        void close(); // Method to close the activity or fragment (Must finish activity or go back in its implementation)
    }
}

You can use this Custom EditText to solve this bug. It refreshes the Error, after keyboard open/close, and your popup will always be displayed correctly.

You must implement close(finish or onBackPressed) and revalidate edittext methods in your class.
