Question

我是android.i中的新手希望在Android中创建一个应用程序，当我错过了我的手机上的一个电话时，我想发送短信给那个号码。任何人都可以帮助我如何识别来自通话记录的最近未接来电。

Answer 1

首先，通过内容提供商获取该号码的未接来电。并轻松发送该号码的短信。

请试一试。

public class MainActivity extends Activity {

    Button FirstActivity;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        String[] strFields = {android.provider.CallLog.Calls.CACHED_NAME, android.provider.CallLog.Calls.NUMBER,android.provider.CallLog.Calls.DATE, android.provider.CallLog.Calls.TYPE
        };
        String strOrder = android.provider.CallLog.Calls.DATE + " DESC";

        Cursor mCallCursor = getContentResolver().query(android.provider.CallLog.Calls.CONTENT_URI,strFields, null, null, strOrder);

        if (mCallCursor.moveToFirst()) {

            do {

                boolean missed = mCallCursor.getInt(mCallCursor.getColumnIndex(CallLog.Calls.TYPE)) == CallLog.Calls.MISSED_TYPE;

                if (missed) {

                    String name = mCallCursor.getString(mCallCursor
                            .getColumnIndex(CallLog.Calls.CACHED_NAME));

                    String number = mCallCursor.getString(mCallCursor
                            .getColumnIndex(CallLog.Calls.NUMBER));

//                  String time = DateFormat.getDateTimeInstance(DateFormat., DateFormat.LONG)
//                          .format(mCallCursor.getLong(mCallCursor
//                                  .getColumnIndex(CallLog.Calls.DATE)));
//
//                  Log.d("PhoneLog", "You have a missed call from " + name + " on " + number
//                          + " at " + time);
                }

            } while (mCallCursor.moveToNext());

        }
        SmsManager smsManager = SmsManager.getDefault();
        smsManager.sendTextMessage("phoneNo", null, "sms message", null, null);
    }

}

阅读CallLogs如果列值为3则有列名称类型，这意味着错过了呼叫且您的应用需要读取呼叫记录的权限More Details
