<1>获取手机联系人

通过短信数据库获取联系人内容：

Activity代码：

packagecom.example.android_readcontacts;importandroid.content.ContentResolver;importandroid.database.Cursor;import.Uri;importandroid.support.v7.app.AppCompatActivity;importandroid.os.Bundle;importandroid.view.View;importandroid.widget.ListView;importandroid.widget.SimpleAdapter;importjava.util.ArrayList;importjava.util.HashMap;importjava.util.List;importjava.util.Map;public classMainActivityextendsAppCompatActivity {privateContentResolvercontentResolver;privateList<Map<String, Object>>data;privateListViewlt_main_listview;privateSimpleAdaptersimpleAdapter;@Overrideprotected voidonCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);lt_main_listview= (ListView) findViewById(R.id.lt_main_listview);//得到内容监听者contentResolver= getContentResolver();//展示数据data=newArrayList<Map<String,Object>>();//准备适配器simpleAdapter=newSimpleAdapter(this,data,android.R.layout.simple_list_item_2,newString[]{"name","phone"},new int[]{android.R.id.text1,android.R.id.text2});//设置适配器lt_main_listview.setAdapter(simpleAdapter);}//获取联系人public voidgetContacts(View view){//获取系统联系人地址Cursor cursor=contentResolver.query(Uri.parse("content://com.android.contacts/raw_contacts"),null,null,null,null);while(cursor.moveToNext()){Map<String,Object> map=newHashMap<>();//获取系统表字段//联系人idintid=cursor.getInt(cursor.getColumnIndex("_id"));//联系人姓名String displayName=cursor.getString(cursor.getColumnIndex("display_name"));//放值map.put("name",displayName);//根据联系人获取联系人数据Cursor cursor2=contentResolver.query(Uri.parse("content://com.android.contacts/raw_contacts/"+id+"/data"),null,null,null,null);while(cursor2.moveToNext()){String type=cursor2.getString(cursor2.getColumnIndex("mimetype"));String data1=null;if("vnd.android.cursor.item/phone_v2".equals(type)){data1 = cursor2.getString(cursor2.getColumnIndex("data1"));map.put("phone",data1);}}//放数据进集合data.add(map);}//通知适配器发生改变simpleAdapter.notifyDataSetChanged();}}

layout代码：
