用FIle Explore 我们可以清楚的看见data-->data目录下的通讯录的数据库的所有信息

导出这个数据库我们就可以看所有通讯录的信息

布局文件

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
    <TextView android:id="@+id/textView1" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="                          请选择查询方式"></TextView>
<Spinner android:layout_height="wrap_content" android:id="@+id/spinner1" android:layout_width="match_parent"></Spinner>
<EditText android:layout_width="match_parent" android:layout_height="wrap_content" android:id="@+id/editText1">
</EditText>
<Button android:layout_width="match_parent" android:layout_height="wrap_content" android:text="查询" android:id="@+id/insert"></Button>
<ListView android:id="@+id/listView1" android:layout_height="wrap_content" android:layout_width="match_parent"></ListView>
</LinearLayout>

最后记得加一个权限

  <uses-permission android:name="android.permission.READ_CONTACTS"></uses-permission>

运行结果
