Hi everyone,
I just want to write a basic program that displays the x, y
coordinates when the screen in touched. Here's my code, any help will
really be appreciated as I'm very much a beginner.
import android.app.Activity;
import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.os.Bundle;
import android.view.MotionEvent;
import android.view.View;
import android.view.View.OnTouchListener;
public class touch_tester extends Activity {
DrawnView dV;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
dV = new DrawnView(this);
setContentView(dV);
}
}
class DrawnView extends View implements OnTouchListener {
Paint paint = new Paint();
float x, y;
public DrawnView(Context context){
super(context);
this.setClickable(true);
setBackgroundColor(Color.WHITE);
this.setOnTouchListener(this);
paint.setColor(Color.BLACK);
paint.setAntiAlias(true);
}
public void onDraw(Canvas c){
c.drawText("X: " + x, 1, 15, paint);
c.drawText("Y: " + y, 1, 30, paint);
}
public boolean onTouch(View view, MotionEvent event){
x = event.getX();
y = event.getY();
return true;
}
}
