Question

我的弹出窗口仍然没有背景。我想要一个白色的弹出窗口，说谁赢了比赛。

爪哇：

    LayoutInflater layoutInflater = (LayoutInflater)getBaseContext().getSystemService(LAYOUT_INFLATER_SERVICE);   
    PopupWindow pw = new PopupWindow(layoutInflater.inflate(R.layout.winner_popup,null, false), LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT); 
    pw.showAtLocation(findViewById(R.id.main_layout), Gravity.CENTER, 0, 0);
    TextView winnerText = (TextView) pw.getContentView().findViewById(R.id.winnerTextView);
    winnerText.setText("Player 1 is the winner"); //Update the TextView

XML：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:background="@color/white">

    <TextView
        android:id="@+id/winnerTextView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/winnerTextViewString"
        android:textAppearance="?android:attr/textAppearanceLarge" />

    <Button
        android:id="@+id/winnerButton"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/winnerButtonString" 
        android:layout_marginLeft="45dp"/>

</LinearLayout>

是否可以或者我应该使用警报窗口？
