使用PendingIntent显示对话框 [英] Show Dialog using PendingIntent

问题描述

我正在处理日历事件提醒。 Android中没有本机的日历事件提醒，因此用户可以安装其他日历应用。

I am working on Calender Events reminder . There is no native Calender events reminder in Android so user install different calender apps.

现在，这些应用在提醒事件（例如可以显示提醒通知）上可以有所不同。现在，我希望我在这些事件日历应用程序中以编程方式设置一个事件，并且在达到指定时间后不显示任何通知，而是会显示一条弹出消息，并发出声音之类的警报。那时候我使用那个站点的代码。

Now these apps can be different on reminding events like on reminder notifications can be shown. Now I want that I set an event programmatically in these event calender apps and on time reached not show any notification rather a pop up message will be shown with alarm like sound. At that I using a code from that site . Its working but it showing reminders in form of notifications.

这里是代码：

OnReceive

OnReceive

void doReminderWork(Intent intent) {
    Long rowId = intent.getExtras().getLong(RemindersDbAdapter.KEY_ROWID);

    NotificationManager mgr = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);

    Intent notificationIntent = new Intent(this, ReminderEditActivity.class); 
    notificationIntent.putExtra(RemindersDbAdapter.KEY_ROWID, rowId); 

    PendingIntent pi = PendingIntent.getActivity(this, 0, notificationIntent, PendingIntent.FLAG_ONE_SHOT); 

    Notification note=new Notification(android.R.drawable.stat_sys_warning, getString(R.string.notify_new_task_message), System.currentTimeMillis());
    note.setLatestEventInfo(this, getString(R.string.notify_new_task_title), getString(R.string.notify_new_task_message), pi);
    note.defaults |= Notification.DEFAULT_SOUND; 
    note.flags |= Notification.FLAG_AUTO_CANCEL; 


    int id = (int)((long)rowId);
    mgr.notify(id, note);
}

现在，我想显示一个对话框而不是通知，以便如何显示

Now I want to show a dialog box instead of notification so how it can be possible from using these lines of code that this pending intent should be used in dialogue box.

 Intent notificationIntent = new Intent(this, ReminderEditActivity.class); 
notificationIntent.putExtra(RemindersDbAdapter.KEY_ROWID, rowId); 

PendingIntent pi = PendingIntent.getActivity(this, 0, notificationIntent, PendingIntent.FLAG_ONE_SHOT); 

推荐答案

在您的接收器类中，只需编写代码即可显示对话框而不是显示通知。

In your Receiver class, just code to get the dialog to display instead of Notification.

显示对话框的类：

public class AlarmDialogPopUp extends Activity
{

    private int m_alarmId;

    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);

        // Get the alarm ID from the intent extra data
        Intent intent = getIntent();
        Bundle extras = intent.getExtras();

        if (extras != null) {
            m_alarmId = extras.getInt("AlarmID", -1);
        } else {
            m_alarmId = -1;
        }

        // Show the popup dialog
        showDialog(0);
    }

    @Override
    protected Dialog onCreateDialog(int id)
    {
        super.onCreateDialog(id);

        // Build the dialog
        AlertDialog.Builder alert = new AlertDialog.Builder(this);

        alert.setTitle("ALARM REMINDER");
        alert.setMessage("Its time for the alarm ");
        alert.setCancelable(false);

        alert.setPositiveButton("Dismiss", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int whichButton) {
                AlarmDialogPopUp.this.finish();
            }
        });

        // Create and return the dialog
        AlertDialog dlg = alert.create();

        return dlg;
    }
}

在您的 onReceive 显示对话框：

In your onReceive to show dialog :

public void onReceive(Context context, Intent intent)
    {
          // Launch the alarm popup dialog
            Intent alarmIntent = new Intent("android.intent.action.MAIN");

            alarmIntent.setClass(context, AlarmDialogPopUp .class);
            alarmIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

            // Pass on the alarm ID as extra data
            alarmIntent.putExtra("AlarmID", intent.getIntExtra("AlarmID", -1));

            // Start the popup activity
            context.startActivity(alarmIntent);

    }

根据评论进行编辑：

要播放声音，您需要使用如下所示的MediaPlayer。

To play sound, you need to make use of MediaPlayer like below.

在 onCreate（）活动类的 AlarmDialogPopUp 播放声音。

MediaPlayer mediaPlayer; //global variable.

    mediaPlayer = MediaPlayer.create(this,R.raw.alarmsound);

在 onClick（）停止声音的对话框：

mediaPlayer.stop();
mediaPlayer.release();

希望这会有所帮助。
