onClickListener在画布

Question

即时通讯开发一个应用程序，它具有对特定图像的选择图像作为一个指数该活动将开始，但我不知道如何设置onClickListener或onTouchListener在画布继承人我的代码

public class DrawView extends View implements OnTouchListener { 

LinearLayout mLayout; 
Bitmap index; 
Bitmap book; 
Bitmap bird; 
Bitmap game; 
Bitmap mail; 
Bitmap music; 
Bitmap torch; 
Paint paint; 

public DrawView(Context context) { 
    super(context); 

    setFocusable(true); 
    setFocusableInTouchMode(true); 
    this.setOnTouchListener(this); 

    index = BitmapFactory.decodeResource(getResources(), R.drawable.photo1); 
    book = BitmapFactory.decodeResource(getResources(), R.drawable.book); 
    game = BitmapFactory.decodeResource(getResources(), R.drawable.game); 
    music = BitmapFactory.decodeResource(getResources(), R.drawable.music); 
} 

public void onDraw(Canvas canvas){ 
    paint = new Paint(); 
    Bitmap indexcanvas = Bitmap.createScaledBitmap(index, canvas.getWidth(), 
                canvas.getHeight(), true); 
    canvas.drawBitmap(indexcanvas, 0, 0, paint); 
    canvas.drawBitmap(book, 160, 100, paint); 
    canvas.drawBitmap(game, 30, 10, paint); 
    canvas.drawBitmap(music, 80, 50, paint); 
} 

public boolean onTouch(View v, MotionEvent event) { 
    return false; 
} 

如有任何人知道如何为特定图像添加onClickListener，例如这里如果我点击Book，bookActivity就会开始。

Answer 1

尝试这样的事：

public boolean onTouch(View v, MotionEvent event) { 
    if((event.getX(0)>=160) && 
     (event.getY(0)>=100) && 
    (event.getX(0)<=160+BOOK_IMG_WIDTH) && 
     (event.getY(0)<=100+BOOK_IMG_HEIGHT)) 
     { 
      //book selected 
     } 
    return true; 
} 

Answer 2

使用ImageView，而不是位图，并把它添加到您的布局：

book = new ImageView(context); 
book.setImageResource(R.drawable.book); 
book.setOnTouchListener(new View.OnTouchListener() { 
     public boolean onTouch(View v, MotionEvent event) { 
      /*...*/ 
     } 
    };);

保存图像COORDS在一个ArrayList。在上下文上设置OnClickListener，获取已点击的点坐标，在数组列表中找到图像并执行某些操作:)
