Question

我想允许用户通过startActivityForResult（）方法在我的应用程序中选择特定联系人的电话号码。可能吗？例如，如果联系人有家庭电话号码和手机号码，则用户可以选择其中一个。

以下代码允许用户选择一个联系人：

    Intent picker = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
    startActivityForResult(picker, 53253);

以下代码允许用户从任何联系人（而非特定联系人）中选择一个电话号码：

    Intent picker = new Intent(Intent.ACTION_PICK, ContactsContract.CommonDataKinds.Phone.CONTENT_URI);
    startActivityForResult(picker, 53253);

使用Mani fest中的权限

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




  <?xml version="1.0" encoding="utf-8" ?> 
- <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.contact" android:versionCode="1" android:versionName="1.0">
  <uses-sdk android:minSdkVersion="8" android:targetSdkVersion="16" /> 
  <uses-permission android:name="android.permission.READ_CONTACTS" /> 
  <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> 
- <application android:allowBackup="true" android:icon="@drawable/ic_launcher" android:label="@string/app_name" android:theme="@style/AppTheme">
- <activity android:name="com.example.contact.MainActivity" android:label="@string/app_name">

  <action android:name="android.intent.action.MAIN" /> 
  <category android:name="android.intent.category.LAUNCHER" />
