下面是我在一个框架中创建了三个新视图的程序。单击两个不同的视图时,我想在视图之间画一条线。我试图弄清楚如何做到这一点......
Ball ball1=new Ball(this,100,100,45);
Ball ball2=new Ball(this,400,100,45);
Ball ball3=new Ball(this,250,350,45);
FrameLayout frame1=(FrameLayout) findViewById(R.id.main_view);
frame1.addView(ball1);
frame1.addView(ball2);
frame1.addView(ball3);
frame1.setOnTouchListener(new View.OnTouchListener() {
public boolean onTouch(View v, MotionEvent event) {
switch(event.getAction()){
case MotionEvent.ACTION_DOWN: {
float x = event.getX();
float y = event.getY();
System.out.println("x:"+x+"y:"+y);
if (x>55 && x<142 && y>55 && y<142)
{
System.out.println("working1 "+count);
Toast toast = Toast.makeText(getBaseContext(), "Works fine", Toast.LENGTH_SHORT);
toast.show();
}
