我正在开发一个应用程序,该应用程序以图像作为索引来选择活动将开始的特定图像,但我不知道如何在 Canvas 中设置 onClickListener 或 onTouchListener 这是我的代码
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;
}
如果有人知道如何为特定图像添加 onClickListener,例如在这里,如果我单击 Book,则 bookActivity 将启动。
