PopupWindow自定义位置显示的实现代码

public class MainActivity extends AppCompatActivity {

  private int x;
  private int y;

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

  }

  @Override
  public boolean onTouchEvent(MotionEvent event) {

    // 获得点击屏幕的坐标

    x = (int) event.getX();
    y = (int) event.getY();

    // 加载PopupWindow 对应的界面
    LayoutInflater inflater = getLayoutInflater();
    final View popupView = inflater.inflate(R.layout.popup_entry_layout,null);

    // 创建PopupWindow 对象
    final PopupWindow popupWindow = new PopupWindow(popupView,400,100); // 第二、第三个参数用来设置弹窗的大小,也可以用WRAP_CONTENT

    // 设置位置
    popupWindow.showAtLocation(popupView, Gravity.NO_GRAVITY,x,y);

    new Handler().postDelayed(new Runnable() {
      @Override
      public void run() {

        // 1秒后关闭该弹窗

        popupWindow.dismiss();

      }
    },1000);

    return true;
  }
}
