还有自定义列表格式

andros_list_item.xml

<?xml version="1.0" encoding="utf-8"?>android:id="@android:id/text1"          xmlns:android="http://schemas.android.com/apk/res/android"          android:layout_width="match_parent"          android:layout_height="wrap_content"          android:gravity="center_vertical"          android:textColor="#000000"          android:textSize="14sp"    />

导入jar包：

AndroidManifest.xml
