利用ContentResolver内容访问者,获取手机联系人信息我做了两种不同的做法。第一种,直接获取所有手机联系人信息,展示在ListView中。第二种,通过Butten按钮跳转到系统的手机联系人界面,单个获取手机联系人信息,展示在ListView中,结果如下:

第一种:直接获取所有手机联系人信息
首先需要在AndroidManifest.xml文件中添加权限:
<uses-permission android:name="android.permission.READ_CONTACTS" /> activity_main.xml布局: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/activity_main" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" tools:context="com.example.android_25.MainActivity"> <ListView android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/lv_lxr" > </ListView> </LinearLayout>
activity_xs.xml布局:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/activity_xs" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" tools:context="com.example.android_25.XsActivity"> <TextView android:layout_width="match_parent" android:layout_height="wrap_content" android:id="@+id/tv_name" /> <TextView android:layout_width="match_parent" android:layout_height="wrap_content" android:id="@+id/tv_telephone" /> </LinearLayout>
MainActivity类:
private ListView lv_lxr; private Button b_name; private ContentResolver cr; private List<Map<String, Object>> datalistView; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); //获得ListView lv_lxr = (ListView) findViewById(R.id.lv_lxr); //得到访问者 cr = getContentResolver(); //定义一个接收联系人姓名和电话号码的集合 datalistView = new ArrayList<>(); 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")); Uri uriData=Uri.parse("content://com.android.contacts/raw_contacts/"+id+"/data"); Cursor contactData= cr.query(uriData,null,null,null,null); //用来装姓名 String aa=""; //用来装号码 String bb=""; while(contactData.moveToNext()){ String type=contactData.getString(contactData.getColumnIndex("mimetype")); //如果获取的是vnd.android.cursor.item/phone_v2则是号码 if(type.equals("vnd.android.cursor.item/phone_v2")){ bb=contactData.getString(contactData.getColumnIndex("data1")); //如果获取的是vnd.android.cursor.item/name则是姓名 }else if(type.equals("vnd.android.cursor.item/name")) { aa=contactData.getString(contactData.getColumnIndex("data1")); } } //将用户名和号码放入Map集合中 Map<String,Object> map=new HashMap<>(); map.put("images",aa); map.put("titles",bb); datalistView.add(map); } SimpleAdapter adapter=new SimpleAdapter(this, datalistView,R.layout.activity_xs,new String[]{"images","titles"},new int[]{R.id.tv_name,R.id.tv_telephone}); lv_lxr.setAdapter(adapter); }
第二种:通过Butten按钮跳转到系统的手机联系人界面,单个获取手机联系人信息,展示在ListView中
activity_contacts.xml布局:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/activity_contacts" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" tools:context="com.example.android_25.ContactsActivity"> <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content"> <Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="跳转到联系人页面" android:id="@+id/b_tzcontacts" /> </LinearLayout> <ListView android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/lv_contacts" ></ListView> </LinearLayout>
ContactsActivity类:
private Button b_tzcontacts; private String phoneName; private String phoneNumber; private List<Map<String,Object>> datalistView; private ListView lv_contacts; private SimpleAdapter adapter; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_contacts); //获得跳转到联系人的id b_tzcontacts =(Button) findViewById(R.id.b_tzcontacts); //获得ListView的ID lv_contacts =(ListView) findViewById(R.id.lv_contacts); //定义一个接受联系人姓名和电话号码的集合 datalistView = new ArrayList<>(); //获取联系人的点击事件 b_tzcontacts.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { Intent intentPhone=new Intent(Intent.ACTION_PICK); intentPhone.setData(ContactsContract.Contacts.CONTENT_URI); startActivityForResult(intentPhone,0); } }); //R.layout.activity_xs就是上文的activity_xs布局问价 adapter = new SimpleAdapter(this, datalistView, R.layout.activity_xs,new String[]{"images","titles"},new int[]{R.id.tv_name,R.id.tv_telephone}); lv_contacts.setAdapter(adapter); } //获得返回的结果 @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); switch (requestCode){ case 0: if(resultCode== Activity.RESULT_OK){ Uri uri=data.getData(); Cursor cursor=managedQuery(uri,null,null,null,null); cursor.moveToFirst(); String contactid=cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID)); //得到ContentResolver ContentResolver contentResolver=getContentResolver(); Cursor phone=contentResolver.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null,ContactsContract.CommonDataKinds.Phone.CONTACT_ID+"="+contactid,null,null); while (phone.moveToNext()){ //联系人 phoneName =phone.getString(phone.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME)); //手机号码 phoneNumber =phone.getString(phone.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)); //格式化手机号 phoneNumber = phoneNumber.replace("-",""); phoneNumber = phoneNumber.replace("",""); //将用户名和号码放入Map集合中 Map<String,Object> map=new HashMap<>(); map.put("images",phoneName); map.put("titles",phoneNumber); datalistView.add(map); } //刷新适配器 adapter.notifyDataSetChanged(); } break; } }
