Question

class扩展AsyncTask。它有3种方法pre，doInBackground和postExecute methods。所以我正在通过postExecute方法拨打电话。

@Override
public void onPostExecute(String result) {
    AlarmManager am = (AlarmManager) context.getSystemService(context.ALARM_SERVICE);
    Intent intent = new Intent(context, OnAlarm.class);
    int time1 = 10000;

    Calendar cal = Calendar.getInstance();
    cal.set(Calendar.SECOND, time1);

    PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent,0);
    long x1=System.currentTimeMillis();
    am.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis() , pendingIntent);
    Toast.makeText(context, "Alarm set",Toast.LENGTH_LONG).show();

    //super.onPostExecute(result);

    Log.v("erororrorororororo", result);
    Log.d("ttttttt", result);
    this.Prog1.setText(result + " pagaaal ");
    line = result;
    Log.v("god save me", line);
    if(result.equals("error")) {
        Log.v("erororrorororororo", line);
    } else {
        //Intent intent1 = new Intent(context, ListMenu.class);
        //context.startActivity(intent1);
    }
}

此OnAlarm课程将接到报警电话。

package com.example.ishanvadwala.server;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.media.MediaPlayer;
import android.util.Log;

/**
 * Created by ruchit on 11/24/15.
 */
public class OnAlarm extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {

       Log.v("BroadcastReceiver", "in onReceive:");
        MediaPlayer mediaPlayer = MediaPlayer.create(context, R.raw.q);
        // Start the MainActivity
        mediaPlayer.start();
        Intent i = new Intent(context, Signup.class);
        i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(i);
    }
}

Answer 1

对不起家伙它的工作应该是PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, intent,0);
而不是PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent,0)

Android闹钟不起作用
