}
public void onKeyDown() {
onBackPressed();
}
}


这是我的list.xml：

android:orientation="vertical" android:layout_
android:layout_>
android:layout_ android:id="@+id/list"/>


这是我的listview.xml：

android:layout_ android:orientation="horizontal"
android:layout_>
android:orientation="vertical" android:layout_>
android:layout_ android:id="@+id/text1"
android:textSize="25dip" android:text="This is text1" />

android:id="@+id/text2"
android:text="This is text2" android:layout_/>

android:layout_ android:id="@+id/img" />


实际上我正在使用一个自定义列表视图.在那里我分别有动物,鸟类和一些随机图像.现在我需要为图像类别赋予标题.即我需要通过在列表中给出标题来根据类别分隔图像.请帮我一个忙.这是我的java编码：

解决方法:

Here是一个使用Section Header的完整示例,也有一个很好的解释.您还可以下载源代码并查看其工作原理.
