这里写图片描述
是用一个ListView显示的

package com.example.android_contentresolver;import android.content.ContentResolver;import android.content.Intent;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;import android.widget.ListView;import android.widget.SimpleAdapter;import java.util.ArrayList;import java.util.HashMap;import java.util.List;import java.util.Map;public class MainActivity extends AppCompatActivity {    private ContentResolver cr;    private ListView list_item_main_lv;    private List list;    private SimpleAdapter simpleAdapter;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        list_item_main_lv = (ListView) findViewById(R.id.list_item_main_lv);        //获取内容访问者        cr = getContentResolver();        list = new ArrayList();        simpleAdapter = new SimpleAdapter(this, list,android.R.layout.simple_list_item_2,new String[]{"sname","data1"},new int[]{android.R.id.text1,android.R.id.text2});        list_item_main_lv.setAdapter(simpleAdapter);    }    public void getLinkman(View view){        //获取系统的        Uri uri = Uri.parse("content://com.android.contacts/raw_contacts");        Cursor cursor =  cr.query(uri,null,null,null,null);        while (cursor.moveToNext()){            Map<String,Object> date=new HashMap<>();            int id = cursor.getInt(cursor.getColumnIndex("_id"));            String name = cursor.getString(cursor.getColumnIndex("display_name"));            date.put("sname",name);            Uri uri1 = Uri.parse("content://com.android.contacts/raw_contacts/"+id+"/data");            Cursor cursor1 = cr.query(uri1,null,null,null,null);            while (cursor1.moveToNext()){                String data1=cursor1.getString(cursor1.getColumnIndex("data1"));                String dateName = cursor1.getString(cursor1.getColumnIndex("mimetype"));                if("vnd.android.cursor.item/phone_v2".equals(dateName)){                    date.put("data1",""+data1);                    list.add(date);                }            }        }        simpleAdapter.notifyDataSetChanged();    }}

在清单文件中添加权限：

<!--获取联系人权限-->    <uses-permission android:name="android.permission.READ_CONTACTS" />
