如何从android中的事件坐标获取视图?

如果有人想知道我做了什么。。。我不能。我做了一个变通方法来确定是否单击了我的特定视图组件,因此我只能以以下内容结束:

   if(isPointInsideView(ev.getRawX(), ev.getRawY(), myViewComponent)){
    doSomething()
   }

方法是:

/**
 * Determines if given points are inside view
 * @param x - x coordinate of point
 * @param y - y coordinate of point
 * @param view - view object to compare
 * @return true if the points are within view bounds, false otherwise
 */
public static boolean isPointInsideView(float x, float y, View view){
    int location[] = new int[2];
    view.getLocationOnScreen(location);
    int viewX = location[0];
    int viewY = location[1];

    //point is inside view bounds
    if(( x > viewX && x < (viewX + view.getWidth())) &&
            ( y > viewY && y < (viewY + view.getHeight()))){
        return true;
    } else {
        return false;
    }
}

但是,这只适用于布局中可以作为参数传递的已知视图,我仍然无法仅通过知道坐标来获取单击的视图。但是,您可以搜索布局中的所有视图。

获取触摸视图的一个简单方法是将OnTouchListener设置为各个视图,并将该视图存储在活动的类变量中。

myView.setOnTouchListener(new OnTouchListener() {
    public boolean onTouch(View v, MotionEvent event) {
    touchedView = myView;
    return false;
    }
}); 


@Override
public boolean onTouchEvent(MotionEvent event) {


    switch (event.getAction()) {

        case MotionEvent.ACTION_UP:

            if(touchedView!=null) {
                doStuffWithMyView(touchedView);
            ....
            ....

只是为了让方法 更简单:

/**
* Determines if given points are inside view
* @param x - x coordinate of point
* @param y - y coordinate of point
* @param view - view object to compare
* @return true if the points are within view bounds, false otherwise
*/
private boolean isPointInsideView(float x, float y, View view) {
    int location[] = new int[2];
    view.getLocationOnScreen(location);
    int viewX = location[0];
    int viewY = location[1];

    // point is inside view bounds
    return ((x > viewX && x < (viewX + view.getWidth())) &&
            (y > viewY && y < (viewY + view.getHeight())));
}
