问题说的听清楚的
看你 这个 ListViewActivity setContentView 里面配置的是那个 xml, 然后看这个xml 第七行，应该是 你写的 listview控件，这个控件有问题，可以发代码再看看
```java
<?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">
<ListView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/lv_1"
android:listSelector="@drawable/list_item">
</ListView>
</LinearLayout>
```
xml布局文件有问题
