推荐答案

您需要捕获单击的UI的位置，该位置是您的过滤器图标 ImageView.您必须使用

You need to catch the location of the clicked UI that is your Filter icon ImageView. You have to use the

getLocationOnScreen() API and PopUpWindow component.

这是用于扩展FilterUI的示例代码

This is the sample code for inflating the FilterUI

    text_click=(TextView)findViewById(R.id.text_click);

          text_click.setOnClickListener(new View.OnClickListener() {
              @Override
              public void onClick(View v) {
                  LayoutInflater inflater= (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
                  int[] locationOfView = new int[2];
                  text_click.getLocationOnScreen(locationOfView);
                  final View mView = inflater.inflate(R.layout.activity_map_view, null, false);
                  final PopupWindow popUp = new PopupWindow(mView, 500, 500, false);
                  popUp.setTouchable(true);
                  popUp.setFocusable(true);
                  popUp.setOutsideTouchable(true);
popUp.setBackgroundDrawable(new ColorDrawable(ContextCompat.getColor(mContext,android.R.color.transparent)));
                  popUp.showAtLocation(mView, Gravity.NO_GRAVITY, locationOfView[0], (locationOfView[1]+ text_click.getHeight()));
              }
          });
