Android: Change custom AlertDialog background
提问by Paulius Vindzigelskis
dialog layout xml:
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>
dialog implementation in map overlay when tapped on pushpin:
点击图钉时地图叠加中的对话框实现：
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();
and what I see when test it:
以及我在测试时看到的内容：
So I want that light grey background around dialog box (around square white space) change to white, so it won't look that ugly. Can anyone help me?
所以我希望对话框周围的浅灰色背景（方形空白周围）变为白色，这样它看起来就不会那么难看。谁能帮我？

I had the same problem, I managed to fix it using a custom dialog like this:
我遇到了同样的问题，我设法使用这样的自定义对话框来修复它：
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);
}
}

Hey setting your view to builder creates this gray lines on top-bottom,instead you can setView to your dialog.like dialog.setView(layout,0,0,0,0);It will bound your layout to whole dialog.
嘿，将您的视图设置为 builder 会在顶部底部创建此灰线，而不是您可以将视图设置为您的 dialog.like dialog.setView(layout,0,0,0,0);它会将您的布局绑定到整个对话框。

Another option is to remove android:background="@android:color/white"from your layout. Then the alert dialog will have its default light grayish background uniformly. (Since you have forced an inverse on a dark theme) At least it would look nice and worth the hassle. Just my two cents.
另一种选择是android:background="@android:color/white"从您的布局中删除。然后警报对话框将统一具有默认的浅灰色背景。（因为你在黑暗主题上强行反转）至少它看起来不错，值得麻烦。只有我的两分钱。
