目前我正在开发一个广播接收器应用程序,我正在制作一个警报,在我们输入秒数后应该显示一条消息。我使用了 RTC_WAKEUP,这意味着它应该在设备打开时显示消息,并且应该打开设备,然后在设备关闭时显示消息。我的问题是它 RTC_WAKEUP 不在我的设备上,但在设备打开时它工作正常。我正在粘贴我的应用程序的代码。在我的应用程序中有两个类。
主要活动
public class MainActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void startAlert(View view) {
EditText text = (EditText) findViewById(R.id.time);
int i = Integer.parseInt(text.getText().toString());
Intent intent = new Intent(this, MyBroadcastReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(this.getApplicationContext(), 23432424, intent, 0);
AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
alarmManager.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis()
+ (i * 1000), pendingIntent);
Toast.makeText(this, "Alarm set in " + i + " seconds",
Toast.LENGTH_LONG).show();
}
}
另一个是
我的广播接收器
public class MyBroadcastReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
Toast.makeText(context, "Jaago Mohan Pyarreee!!!!.",
Toast.LENGTH_LONG).show();
}
}
