在之前项目中有用到关于获取手机联系人的部分，闲置就想和大家分享一下，话不多说，上代码:
java部分:
package com.example.content;
import android.content.ContentResolver;
import android.database.Cursor;
import android.net.Uri;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
public class MainActivity extends AppCompatActivity {
private ContentResolver cr;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//获取内容访问者
cr = getContentResolver();
}
public void getContacts(View view){
Uri uri=Uri.parse("content://com.android.contacts/raw_contacts");
Cursor cursor=cr.query(uri,null,null,null,null);
while(cursor.moveToNext()){
int _id=cursor.getInt(cursor.getColumnIndex("_id"));
String display_name=cursor.getString(cursor.getColumnIndex("display_name"));
Log.i("test",_id+" "+display_name);
Uri uriData=Uri.parse("content://com.android.contacts/raw_contacts/"+_id+"/data");
Cursor cursorData=cr.query(uriData,null,null,null,null);
while(cursorData.moveToNext()){
String mimetype=cursorData.getString(cursorData.getColumnIndex("mimetype"));
String data1=cursorData.getString(cursorData.getColumnIndex("data1"));
if("vnd.android.cursor.item/phone_v2".equals(mimetype)){
Log.i("test"," "+mimetype+" "+data1);
}
}
}
}
}
xml部分：
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" tools:context="com.example.content.MainActivity"> <Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="获取手机联系人" android:onClick="getContacts" /> </LinearLayout>
在需要获取系统的东西的时候一定不要忘记给权限啊
AndroidManifest.xml部分：
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.content">
<!--获取手机的联系人-->
<uses-permission android:name="android.permission.READ_CONTACTS"></uses-permission>
<application android:allowBackup="true" android:icon="@mipmap/ic_launcher"
android:label="@string/app_name" android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true" android:theme="@style/AppTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持。
