Android中使用ContentProvider获取联系人

@Override
			public void onClick(View v) {
					// 系统的ContentProvider通过联系人的Uri获取数据
					Cursor cursor = getContentResolver().query(
							ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
							null, null, null, null);
					while(cursor.moveToNext()){
						String name = cursor.getString(cursor
								.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
						Log.d("jyq", "name ========"+name);
						String num = cursor
								.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
						Log.d("jyq", "num ========="+num);
					}
			}
		});
    }

在清单文件中添加权限：

 

    <uses-permission android:name="android.permission.READ_CONTACTS"/>
    <uses-permission android:name="android.permission.WRITE_CONTACTS"/>

就OK了
