Question

我正在编写我的闹钟应用程序的基础知识，我希望用户指定他们希望闹钟关闭的时间，然后当它关闭时显示祝酒消息并播放声音直到停止闹钟。我的下面的代码允许他们设置闹钟，但是当达到指定的时间时，不会发生吐司消息或声音事件。任何帮助都会很棒，我的代码如下，我的MainActivity.java文件：

package com.alarm.mobilegame;

import java.util.Calendar;
import android.app.Activity;
import android.app.AlarmManager;
import android.app.PendingIntent;
import android.app.TimePickerDialog;
import android.app.TimePickerDialog.OnTimeSetListener;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.TextView;
import android.widget.TimePicker;

public class MainActivity extends Activity {

TimePicker myTimePicker;
Button buttonstartSetDialog;
TextView textAlarmPrompt;
TimePickerDialog timePickerDialog;
Button cancelalarm;

final static int RQS_1 = 1;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    textAlarmPrompt = (TextView) findViewById(R.id.alarmprompt);

    buttonstartSetDialog = (Button) findViewById(R.id.startAlarm);
    buttonstartSetDialog.setOnClickListener(new OnClickListener() {

        @Override
           public void onClick(View v) {
            textAlarmPrompt.setText("");
            openTimePickerDialog(false);

           }});

                cancelalarm = (Button)findViewById(R.id.cancel);
                cancelalarm.setOnClickListener(new OnClickListener(){

           @Override
           public void onClick(View arg0) {
            cancelAlarm();
           }});

            }

private void openTimePickerDialog(boolean is24r) {
    Calendar calendar = Calendar.getInstance();

    timePickerDialog = new TimePickerDialog(MainActivity.this,
            onTimeSetListener, calendar.get(Calendar.HOUR_OF_DAY),
            calendar.get(Calendar.MINUTE), is24r);
    timePickerDialog.setTitle("Set Alarm Time");

    timePickerDialog.show();
}

OnTimeSetListener onTimeSetListener = new OnTimeSetListener() {

    @Override
    public void onTimeSet(TimePicker view, int hourOfDay, int minute) {

        Calendar calNow = Calendar.getInstance();
        Calendar calSet = (Calendar) calNow.clone();

        calSet.set(Calendar.HOUR_OF_DAY, hourOfDay);
        calSet.set(Calendar.MINUTE, minute);
        calSet.set(Calendar.SECOND, 0);
        calSet.set(Calendar.MILLISECOND, 0);

        if (calSet.compareTo(calNow) <= 0) {
            // Today Set time passed, count to tomorrow
            calSet.add(Calendar.DATE, 1);
        }
        setAlarm(calSet);
    }
};

private void setAlarm(Calendar targetCal) {

    textAlarmPrompt.setText("\n\n***\n" + "Alarm is set "
            + targetCal.getTime() + "\n" + "***\n");

    Intent intent = new Intent(getBaseContext(), Receiver.class);
    PendingIntent pendingIntent = PendingIntent.getBroadcast(
            getBaseContext(), RQS_1, intent, 0);
    AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
    alarmManager.set(AlarmManager.RTC_WAKEUP, targetCal.getTimeInMillis(),
            pendingIntent);
    }
private void cancelAlarm(){

    textAlarmPrompt.setText(
        "\n\n***\n"
        + "Alarm Cancelled! \n"
        + "***\n");

      Intent intent = new Intent(getBaseContext(), Receiver.class);
      PendingIntent pendingIntent = PendingIntent.getBroadcast(getBaseContext(), RQS_1, intent, 0);
      AlarmManager alarmManager = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
      alarmManager.cancel(pendingIntent);

     }

}

我的Receiver.java文件：

package com.alarm.mobilegame;

import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.net.Uri;
import android.support.v4.app.NotificationCompat;
import android.widget.Toast;

public class Receiver extends BroadcastReceiver {

 private static final int MY_NOTIFICATION_ID=1;
 NotificationManager notificationManager;
 Notification myNotification;
 private final String myBlog = "";

 @Override
 public void onReceive(Context context, Intent intent) {
 Toast.makeText(context, "Alarm received!", Toast.LENGTH_LONG).show();

 Intent myIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(myBlog));
 PendingIntent pendingIntent = PendingIntent.getActivity(
        context, 
        0, 
        myIntent, 
        Intent.FLAG_ACTIVITY_NEW_TASK);

 myNotification = new NotificationCompat.Builder(context)
   .setContentTitle("Exercise of Notification!")
   .setContentText("http://android-er.blogspot.com/")
   .setTicker("Notification!")
   .setWhen(System.currentTimeMillis())
   .setContentIntent(pendingIntent)
   .setDefaults(Notification.DEFAULT_SOUND)
   .setAutoCancel(true)
   .setSmallIcon(R.drawable.ic_launcher)
   .build();

 notificationManager = 
   (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);
 notificationManager.notify(MY_NOTIFICATION_ID, myNotification);
 }
}

这是我的清单文件：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.alarm.mobilegame"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
    android:minSdkVersion="9"
    android:targetSdkVersion="19" />

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name="com.alarm.mobilegame.MainActivity"
        android:label="@string/text" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
     <receiver android:name=".Receiver" android:process=":remote" />
</application>
</manifest>

注意：Eclipse没有显示任何警告或错误，这使我认为我的代码没有按照我的意愿执行或认为它应该执行。

在Android模拟器应用程序中警报响起时没有声音或Toast消息
