我是 android 的新手。我希望在 android 中创建一个应用程序，当我错过手机上的电话时，我想向该号码发送一条短信。任何人都可以帮助我如何从通话记录中识别最近未接来电。

首先，通过内容提供商获取该号码的未接电话。然后轻松发送该号码的短信。

请试试这个。

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);
    }

}

Read CallLogs 存在列名类型，如果值为 3，则表示未接来电，您的应用需要读取通话记录的权限更多详情
