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
