Android:如何防止任何触摸事件从视图传递到视图下方? [英] Android: How to prevent any touch events from being passed from a view to the one underneath it?

问题描述

专门使用下面的代码，有没有办法对其进行修改，以使这个新创建的视图下的活动不接收任何手势?

Specifically using the code below, is there a way to modify it so that the activity under this newly created view does not receive any gestures?

View v1 = new View(this);    
WindowManager.LayoutParams params = new WindowManager.LayoutParams(
 1000,
 50,
 WindowManager.LayoutParams.TYPE_SYSTEM_ALERT,
 WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE |
 WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN,
 PixelFormat.OPAQUE);

params.gravity = Gravity.BOTTOM;
WindowManager wm = (WindowManager) this.getSystemService(Context.WINDOW_SERVICE);
wm.addView(v1, params);

推荐答案

向顶部位置的视图添加 onTouchEvent 方法，然后返回true.True会告诉事件冒泡该事件已被消耗，因此可以防止事件冒泡至其他视图.

Add an onTouchEvent method to the view with top position then return true. True will tell the event bubbling that the event was consumed therefore prevent event from bubbling to other views.

protected boolean onTouchEvent (MotionEvent me) {
    return true;
}

对于 v1 ，您需要导入:

import android.view.View.OnTouchListener;

然后设置onTouchListener:

Then set the onTouchListener:

v1.setOnTouchListener(new OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
        return true;
    }
});
