화면이 터치되었을 때, X 좌표 및 Y 좌표를 알아내는 방법

1. MainActivity.java

 

package ...
 
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.MotionEvent;
import android.view.View;
import android.widget.EditText;
import android.widget.FrameLayout;
 
public class MainActivity extends AppCompatActivity {
    EditText editText;
    EditText editText2;
 
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
 
        editText = (EditText) findViewById(R.id.editText);
        editText2 = (EditText) findViewById(R.id.editText2);
 
        FrameLayout layout1 = (FrameLayout) findViewById(R.id.layout1);
 
        layout1.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                float x = event.getX();
                float y = event.getY();
 
                editText.setText(String.valueOf(x));
                editText2.setText(String.valueOf(y));
 
                return true;
            }
        });
 
    }
}
