我有上面的代码可以将数据添加到 ListView 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" >

我想动态地填充 TextView ，我在数组列表中得到了所有内容，但是我的 getView 方法没有被调用。
最佳答案
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 View 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() 之一将对象添加到适配器的方法..
关于java - 我的 getView 方法没有被调用以在 ListView 中填充数据，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/13506698/
