我有上面的代码可以将数据添加到列表视图中，但是我的 getview 方法没有被调用，请告诉我原因。

我的 listview xml 如下所示

<ListView
        android:id="@android:id/list"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_above="@+id/imageView2"
        android:layout_alignRight="@+id/imageButton5"
        android:layout_below="@+id/textView1" >

我的列表布局格式如下所示

</RelativeLayout>

我想动态填充文本视图，我得到了数组列表中的所有内容，但我的 getView 方法没有被调用。

您没有将字符串数组传递给ArrayAdapter..ArrayAdapter使用传递的列表来计算要在视图中显示的项目数..

查看ArrayAdapter的 javadoc 。您要么需要将对象数组发送到其构造函数，要么调用add()方法之一将对象添加到适配器。

您错过了getCount()adatper的方法。只需覆盖getCount方法并返回适当的计数。以下方法将强制您的getView被调用5次 

@Override
    public synchronized int getCount() {
        return 5;
    }
