利用ContentResolver內容訪問者，獲取手機聯系人信息我做了兩種不同的做法。第一種，直接獲取所有手機聯系人信息，展示在ListView中。第二種，通過Butten按鈕跳轉到系統的手機聯系人界面，單個獲取手機聯系人信息，展示在ListView中，結果如下：

第一種：直接獲取所有手機聯系人信息
首先需要在AndroidManifest.xml文件中添加權限：
<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類：
private ListView lv_lxr;private Button b_name;private ContentResolver cr;private List<Map<String, Object>> datalistView;@Overrideprotected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); //獲得ListView lv_lxr = (ListView) findViewById(R.id.lv_lxr); //得到訪問者 cr = getContentResolver(); //定義一個接收聯系人姓名和電話號碼的集合 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); //用來裝姓名 String aa=""; //用來裝號碼 String bb=""; while(contactData.moveToNext()){ String type=contactData.getString(contactData.getColumnIndex("mimetype")); //如果獲取的是vnd.android.cursor.item/phone_v2則是號碼 if(type.equals("vnd.android.cursor.item/phone_v2")){ bb=contactData.getString(contactData.getColumnIndex("data1")); //如果獲取的是vnd.android.cursor.item/name則是姓名 }else if(type.equals("vnd.android.cursor.item/name")) { aa=contactData.getString(contactData.getColumnIndex("data1")); } } //將用戶名和號碼放入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);}第二種：通過Butten按鈕跳轉到系統的手機聯系人界面，單個獲取手機聯系人信息，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="跳轉到聯系人頁面" 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類：
private Button b_tzcontacts;private String phoneName;private String phoneNumber;private List<Map<String,Object>> datalistView;private ListView lv_contacts;private SimpleAdapter adapter;@Overrideprotected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_contacts); //獲得跳轉到聯系人的id b_tzcontacts =(Button) findViewById(R.id.b_tzcontacts); //獲得ListView的ID lv_contacts =(ListView) findViewById(R.id.lv_contacts); //定義一個接受聯系人姓名和電話號碼的集合 datalistView = new ArrayList<>(); //獲取聯系人的點擊事件 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布局問價 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);} //獲得返回的結果@Overrideprotected 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()){ //聯系人 phoneName =phone.getString(phone.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME)); //手機號碼 phoneNumber =phone.getString(phone.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)); //格式化手機號 phoneNumber = phoneNumber.replace("-",""); phoneNumber = phoneNumber.replace("",""); //將用戶名和號碼放入Map集合中 Map<String,Object> map=new HashMap<>(); map.put("images",phoneName); map.put("titles",phoneNumber); datalistView.add(map); } //刷新適配器 adapter.notifyDataSetChanged(); } break; }}以上就是本文的全部內容，希望對大家的學習有所幫助，也希望大家多多支持武林網。
