我已经在按钮点击时创建了 AlarmManager,但是当手机重新启动时它不起作用。我的 AlarmBroadcastReceiver 在手机重启时没有被调用。它可以在手机锁屏或应用程序被关闭后工作,但是在手机重新启动后不能正常工作。我创建了一个进度条,当按钮被点击时开始,当闹钟广播被触发时停止,但是当手机重新启动时它无法停止。我已经添加了按钮点击事件和广播接收器类。
按钮点击事件
按钮点击事件
b1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
pb1.setVisibility(View.VISIBLE);
progress_edit.putBoolean("progress_one", true);
progress_edit.apply();
AlarmManager manager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
Intent intnt = new Intent(getApplicationContext(), AlarmbroadcastReceiver.class);
intnt.setAction("com.ex.Alarm");
PendingIntent pending = PendingIntent.getBroadcast(getApplicationContext(), 0, intnt, 0);
manager.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + 120000, pending);
Log.d("Broadcast ","Fired");
}
});
BroadcastReceiver类
@Override
public void onReceive(Context context, Intent intent) {
Log.d("inside","broadcast receive");
if(intent.getAction().equalsIgnoreCase("com.ex.Alarm"))
{
enterSys_progress_edit.putBoolean("progress_one", false);
enterSys_progress_edit.apply();
Toast.makeText(context,"Receive",Toast.LENGTH_LONG).show();
}
}
