Use KeyEvent in Button onClick

I want to use KeyEvent example KEYCODE_0 Link in button onClick

<Button
              android:id="@+id/Btnequal_id"
              android:layout_width="wrap_content"
              android:layout_height="60dp"
              android:layout_weight="1"
              android:onClick="0x00000007"
              android:text="=" />

get instance of your EditText on which you wanna apply keyEvent listener,then setOnKeyListner on your edittext like below.

mPinBox4 = (EditText) findViewById(R.id.pinVerifyBox4);

    mPinBox4.setOnKeyListener(new View.OnKeyListener() {
        @Override
        public boolean onKey(View v, int keyCode, KeyEvent event) {

            if (keyCode==KeyEvent.KEYCODE_0){
                //excute what ever you want when KEYCODE_0 is pressed
            }
            return false;
        }
    });
