1 用隱式Intent獲取聯系人

第一步、在需要讀取或者修改聯系人信息的前要在manifests文件下聲明讀寫權限，否則在后續的調用中會出錯

    <uses-permission android:name="android.permission.READ_CONTACTS"></uses-permission>     第二步采用ACTION_PICK為動作聲明一個隱式Intent。
  
 bt_main_button = (Button) findViewById(R.id.bt_main_button);        bt_main_button.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                Intent i = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);   //聲明隱式Intent，從聯系人中獲取一個返回信息                startActivityForResult(i,RESULT_CANCELED);            }        });
第三步、在onActivityResult中獲取返回的URI，該URI是指向用戶所選的聯系人的定位符，通過該URI可以查詢聯系人數據庫從而提取出聯系人id與姓名。而通過聯系人id可以進一步在數據庫中提取出聯系人的電話。其中聯系人名字和id要在ContactsContract.Contacts中獲取，而電話則ContactsContract.CommonDataKinds.Phone中獲取。
 @Override    PRotected void onActivityResult(int requestCode, int resultCode, Intent data) {        if (requestCode == RESULT_CANCELED){            Uri contactUri = data.getData();             //該數據URI是一個指向用戶所選聯系人的定位符            Cursor c =getContentResolver().query(contactUri, null, null, null, null); //查詢聯系人數據庫，獲得一個可用的Cursor            if(c.moveToFirst()) {                        //將Cursor移動到第一條記錄                String suspect = c.getString(c.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));        //通過Cursor c獲得聯系人名字                String id = c.getString(c.getColumnIndex(ContactsContract.Contacts._ID));                      //通過Cursor c獲得聯系人id                Cursor c2 =getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,                 ContactsContract.CommonDataKinds.Phone.CONTACT_ID + "=" + id, null, null);                //在ContactsContract.CommonDataKinds.Phone.CONTENT_URI里，                // 通過上面獲得的聯系人id獲得一個新的Cursor c2                c2.moveToFirst();                String phonenum = c2.getString(c2.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));   //通過Cursor c2獲得聯系人電                //給控件賦值                tv_main_view.setText(suspect+"      "+phonenum);                c2.close();                    //關閉Cursor c2                c.close();                     //關閉Cursor c            }        }    }
2 通過ContentProvider得到手機上所有聯系人的信息   
           第一步    在manifests文件下聲明讀寫權限 與隱式intent一樣的
  <uses-permission android:name="android.permission.READ_CONTACTS"></uses-permission>           第二步 得到內容訪問者
  ContentResolver cr=getContentResolver();            第三步  得到手機中所有的聯系人的信息并展示在listview中  
    
    List<String> namelist=new ArrayList<>();    List<String> tellist=new ArrayList<>();    //ContentProvider得到所有聯系的信息    public void getContacts(View view){       //獲取聯系人        Uri uri=Uri.parse("content://com.android.contacts/raw_contacts");         Cursor cursor= cr.query(uri,null,null,null,null);         while(cursor.moveToNext()){             //得到聯系人是id             int id=cursor.getInt(cursor.getColumnIndex("_id"));             String name=cursor.getString(cursor.getColumnIndex("display_name"));         //    Log.i("text", "getContacts: "+id+name);             //獲取相對應的聯系人的數據（電話號碼）             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 data1=cursorData.getString(cursorData.getColumnIndex("data1"));                 //int type=cursorData.getInt(cursorData.getColumnIndex("mimetype_id"));                 //得到數據的類型（郵件地址，電話號碼等等）這里我們只需得到電話號碼                 String type=cursorData.getString(cursorData.getColumnIndex("mimetype"));                 if("vnd.android.cursor.item/phone_v2".equals(type)){                       namelist.add(name);                       tellist.add(data1);                 }             }         }        List<Map<String,Object>> date=new ArrayList<>();        for (int i = 0; i <namelist.size() ; i++) {            Map<String,Object> map=new HashMap<>();            map.put("name",namelist.get(i));            map.put("tel",tellist.get(i));            date.add(map);        }        SimpleAdapter adpater=new SimpleAdapter(this,date,R.layout.item_list,new String[]{"name","tel"},new int[]{R.id.tv_list_name,R.id.tv_list_apont} );         lv_main_view.setAdapter(adpater);        lv_main_view.setOnItemClickListener(new AdapterView.OnItemClickListener() {            @Override            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {                tv_main_view.setText(namelist.get(position)+"      "+tellist.get(position));            }        });    }
