我在linearlayout上添加了一个ontouchlistener,其中包括TextView和ImageView。当我触摸它工作的TextView部分时,ImageView不起作用。我希望所有的linearlayout都可以获得触摸事件。我该怎么办?我的XML如下:

这是我的代码:
dingyueLL.setOnTouchListener(new OnTouchListener()
{
@Override
public boolean onTouch(View v, MotionEvent event)
{
setFlagTrue(Navigation.Dingyue.getPosition());
setBtnLine();
return false;
}
});

使用onintercepttouchevent
创建自定义线性布局。
public class MyLayout extends LinearLayout {
@Override
public boolean onInterceptTouchEvent(MotionEvent ev) {
// do whatever you want with the event
// and return true so that children don't receive it
return true;
}
}

我要尝试的是明确地向图像添加触摸侦听器,并查看发生的情况。在这个监听器中,不要调用supper,并返回false,这样事件就会传播到下一个监听器,希望布局
dingyueLL.setOnTouchListener(new OnTouchListener()
{
@Override
public boolean onTouch(View v, MotionEvent event)
{
setFlagTrue(Navigation.Dingyue.getPosition());
setBtnLine();
return false;
}
});
THEIMAGE.setOnTouchListener(new OnTouchListener()
{
@Override
public boolean onTouch(View v, MotionEvent event)
{
return false;
}
});
另外,在图像的监听器的ontouch函数中放置一个断点,看它是否到达那里
