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。
