Android之获取联系人

今天来教大家怎么获取手机联系人，很简单啊！就不做过多讲解

首先获取内容访问者

public class MainActivity extends AppCompatActivity {

    private ContentResolver cr;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        //获取内容访问者
        cr = getContentResolver();
    }
    public void getContacts(View view){
        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"));
            String display_name=cursor.getString(cursor.getColumnIndex("display_name"));
            Log.i("test",_id+" "+display_name);

            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 mimetype=cursorData.getString(cursorData.getColumnIndex("mimetype"));
                String data1=cursorData.getString(cursorData.getColumnIndex("data1"));
                if("vnd.android.cursor.item/phone_v2".equals(mimetype)){
                    Log.i("test","     "+mimetype+" "+data1);
                }
            }
        }
    }

简简单单的Java代码，再进行配置就OK了！
