我最近實現了一個PopupWindow,它完全顯示在我點擊我的GoogleMapv2的位置上。 我將LatLng地圖位置轉換爲screenlocation,將重力設置爲居中並顯示在屏幕上。然後,沒有任何代碼的變化,它開始顯示在點擊點上方,我不知道什麼是錯的。請幫忙!我渴望任何解決方案,我的問題,我只是想顯示一個進度對話框到地圖上點擊的點。如何顯示PopupWindow居中點擊屏幕上的點?

這裏是我的代碼:

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繪製:

<?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>

是該應用程序並沒有顯示在全屏的問題,所以從點擊LatLng轉換的屏幕點與實際屏幕點不一致,偏移量爲Android上面板的高度。當我全屏製作應用時,它有所幫助。不過,我仍然不知道熱得到Android頂部面板的高度......
