安卓：更改自定义AlertDialog背景(Android: Change custom Alert

对话框布局XML：

<?xml version="1.0" encoding="utf-8"?>
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
     android:id="@+id/root_view"
     android:padding="3dp"
     android:background="@android:color/white"
     android:layout_width="wrap_content"
     android:layout_height="wrap_content" >

     //...content...

 </TableLayout>

在地图覆盖对话框执行上图钉挖掘时：

AlertDialog.Builder builder;

LayoutInflater inflater = (LayoutInflater) context.getSystemService(Service.LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(R.layout.map_kap_dialog,
                    (ViewGroup) mapView.findViewById(R.id.root_view));

//prepare info to show...
//info prepared

//other preparations stuff
builder = new AlertDialog.Builder(context);
builder.setView(layout);
dialog = builder.create();
dialog.setInverseBackgroundForced(true);
dialog.setCanceledOnTouchOutside(true);
//show it
dialog.show();

而我所看到的，当测试：

所以我想，大约对话框（约方空格）变化浅灰色的背景为白色，所以它不会显得难看。谁能帮我？

Answer 1:

我有同样的问题，我设法使用这样一个自定义对话框来解决它：

public class CustomDialog extends Dialog {
    public CustomDialog(Context context, View view) {
        super(context);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(view);
        getWindow().getDecorView().setBackgroundResource(android.R.color.transparent);
    }
}
