Android 读取系统联系人

以下是一个小demo比较简单

XML代码：

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools" android:id="@+id/activity_main"    android:layout_width="match_parent" android:layout_height="match_parent"    android:paddingBottom="@dimen/activity_vertical_margin"    android:paddingLeft="@dimen/activity_horizontal_margin"    android:paddingRight="@dimen/activity_horizontal_margin"    android:paddingTop="@dimen/activity_vertical_margin"    android:orientation="vertical"    tools:context="com.dzz.android23_ecd.MainActivity">    <TextView        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:text="黑名单"/>    <LinearLayout        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:orientation="horizontal">        <EditText            android:layout_width="0dp"            android:layout_height="wrap_content"            android:hint="请输入黑名单号码"            android:id="@+id/et_main"            android:phoneNumber="true"            android:layout_weight="6"            />        <Button            android:layout_width="0dp"            android:layout_height="wrap_content"            android:layout_weight="2"            android:text="联系人"            android:onClick="phone"            />    </LinearLayout>    <Button        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="设置为"        android:onClick="set"        android:layout_gravity="center"        /></LinearLayout>
