我最近实现了一个 PopupWindow，它恰好显示在我单击 GoogleMapv2 的位置。我将 LatLng 地图位置转换为屏幕位置，将重力设置为中心并显示在屏幕上。然后，在没有任何代码更改的情况下，它开始显示在点击点上方一点，我不知道出了什么问题。请帮忙！我渴望任何解决我的问题的方法，我实际上只是想在地图上的点击点上显示一个进度对话框。

这是我的代码：

mMap.setOnMapClickListener(new OnMapClickListener()
        {
            @Override
            public void onMapClick(LatLng point)
            {       
    View popUpView = getLayoutInflater().inflate(R.layout.popup, null); 
    LinearLayout layout = (LinearLayout) popUpView.findViewById(R.id.popup);
      ProgressBar progressBar = new ProgressBar(MainActivity.this);        
          progressBar.setIndeterminateDrawable(getResources().getDrawable(R.drawable.dialog));
    layout.addView(progressBar);

    mpopup = new PopupWindow(popUpView, 30,30, false); //Creation of popup
    mpopup.setOnDismissListener(MainActivity.this);
    mpopup.setAnimationStyle(android.R.style.Animation_Dialog);             
    pinToScreen(point, popUpView);
            }
        });
    }
}

private void pinToScreen(LatLng point, View popupView)
{
    Projection projection = mMap.getProjection();       
    Point pixPoint = projection.toScreenLocation(point);
    LatLng latlng=projection.fromScreenLocation(pixPoint);
    DisplayMetrics dm = getResources().getDisplayMetrics();
    int screenwidth = dm.widthPixels;
    int screenheight = dm.heightPixels;     
    mpopup.showAtLocation(popupView, Gravity.CENTER,
                                  pixPoint.x-screenwidth/2, pixPoint.y-screenheight/2;      
}

R.layout.popup：

LinearLayout
 xmlns:android="http://schemas.android.com/apk/res/android"
 android:id="@+id/popup"
 android:layout_width="fill_parent"
 android:orientation="vertical"
 android:background="@android:color/transparent"
 android:layout_height="fill_parent"
 android:gravity="center"
 android:layout_gravity="center">
LinearLayout>

ProgressDialog 可绘制：

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" 
android:shape="oval"
android:visible="true"
android:innerRadius="60dp"

><solid 
    android:color="@color/skypicker_blue1"       
    />
<stroke android:color="@color/transparent_blue2"
    android:width="1dp"/>

</shape>

The problem was that the application was not displayed on fullscreen, so the screenpoint converted from clicked LatLng did not correspond with the actual screenpoint, the offset was the height of the top panel on Android. When I made the app fullscreen, it helped. However, I still don´t know hot to get height of the Android top panel...
