最近有個朋友問了我如何接受指定號碼的簡訊,並且不讓系統截取到通知使用者。真好前端時間看天朝group,也有個朋友問了這個問題,而且通過 ContentObserver方式解決了。我這裡就把我實現的代碼貼出來,以便需要的朋友參考。
監聽相應的URI的ContentProvider就可以,在OnChange實現你想做的事情或者發廣播等。
[java]
view plaincopy
- public class ScreenTest extends Activity {
- class SmsContent extends ContentObserver {
- private Cursor cursor = null;
- public SmsContent(Handler handler) {
- super(handler);
- }
-
- /**
- * @Description 當簡訊表發送改變時,調用該方法
- * 需要兩種許可權
- * android.permission.READ_SMS 讀取簡訊
- * android.permission.WRITE_SMS 寫簡訊
- * @Author Snake
- * @Date 2010-1-12
- */
- @Override
- public void onChange(boolean selfChange) {
- // TODO Auto-generated method stub
- super.onChange(selfChange);
- // 讀取收件匣中指定號碼的簡訊
- cursor = managedQuery(Uri.parse("content://sms/inbox"), new String[]{"_id", "address", "read"}, " address=? and read=?", new String[]{"12345678901", "0"}, "date desc");
- if (cursor != null) {
- ContentValues values = new ContentValues();
- values.put("read", "1"); //修改簡訊為已讀模式
- cursor.moveToFirst();
- while (cursor.isLast()){
- //更新當前未讀簡訊狀態為已讀
- getContentResolver().update(Uri.parse("content://sms/inbox"), values, " _id=?", new String[]{""+cursor.getInt(0)});
- cursor.moveToNext();
- }
- }
- }
- }
-
- /** Called when the activity is first created. */
- @Override
- public void onCreate(Bundle savedInstanceState) {
- super.onCreate(savedInstanceState);
- setContentView(R.layout.main);
- SmsContent content = new SmsContent(new Handler());
- //註冊簡訊變化監聽
- this.getContentResolver().registerContentObserver(Uri.parse("content://sms/"), true, content);
- }
- }
