android，我不了解我的子类ImageView中的长按检测
||
你好
我是触摸屏编程的新手，请给我一些帮助！
我有：
public class PhotoEditDrawView extends ImageView {
@Override
public boolean onTouchEvent(MotionEvent event) {
setOnLongClickListener(new OnLongClickListener() {
@Override
public boolean onLongClick(View v) {
Toast.makeText(ctx, \"hello hello \", Toast.LENGTH_SHORT).show();
return true;
}
});
onLongClick
onTouchEvent
没有找到相关结果

public class MyImageView extends ImageView { private Context mContext; public MyImageView(Context context) { super(context); setBackgroundColor(Color.RED); mContext = context; setOnLongClickListener(new OnLongClickListener() { @Override public boolean onLongClick(View v) { Toast.makeText(mContext, \"hello hello \", Toast.LENGTH_SHORT).show(); return true; } }); } @Override public boolean onTouchEvent(MotionEvent event) { // TODO Auto-generated method stub return super.onTouchEvent(event); } }傻寺俊擒
