我还有一个问题，如何使图片显示在内容区域而不是图标中。你能再帮我吗？所以这是您的完整代码：
XML：（alert_background.xml）
<?xml version="1.0" encoding="utf-8"?><ScrollView xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:padding="15dp" > <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="vertical" > <ImageView android:id="@+id/imageView1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center" android:src="@drawable/ic_launcher" /> <TextView android:id="@+id/textView1" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_margin="10dp" android:gravity="center" android:text="TextView" android:textAppearance="?android:attr/textAppearanceLarge" /> <TextView android:id="@+id/textView2" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_margin="10dp" android:gravity="center" android:text="TextView" android:textAppearance="?android:attr/textAppearanceLarge" /> <TextView android:id="@+id/textView3" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_margin="10dp" android:gravity="center" android:text="TextView" android:textAppearance="?android:attr/textAppearanceLarge" /> </LinearLayout></ScrollView>
