将通知添加到Android应用程序

我想为我的Android应用程序实现通知,但我不知道哪个类最适合该任务。

我刚看过AlarmManager,这类电池是否友好?

如果是,有人可以举例说明如何为未来事件设置通知(例如,我设置后2或3天)吗?

我有这个源代码作为示例,它应该在30秒后通过警报和Toast消息通知我,但是不起作用。

package com.rNetworks.testAlarm;

import java.util.Calendar;

import android.app.Activity;
import android.app.AlarmManager;
import android.app.PendingIntent;
import android.content.Intent;
import android.os.Bundle;
import android.os.SystemClock;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.Toast;

public class AndroidTestAlarmActivity extends Activity {

    private PendingIntent mAlarmSender;


    private OnClickListener lstStart= new OnClickListener(){

        @Override
        public void onClick(View arg0) {
            //
            // We want the alarm to go off 30 seconds from now.
            long firstTime = SystemClock.elapsedRealtime();

            // Schedule the alarm!
            AlarmManager am = (AlarmManager)getSystemService(ALARM_SERVICE);
            am.setRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP,
                            firstTime, 30*1000, mAlarmSender);

            // Tell the user about what we did.
            Toast.makeText(AndroidTestAlarmActivity.this, "sdasdads",
                    Toast.LENGTH_LONG).show();

        }

    };

    private OnClickListener lstStop= new OnClickListener(){

        @Override
        public void onClick(View v) {
            AlarmManager alarmManager =(AlarmManager)getSystemService(ALARM_SERVICE);
            alarmManager.cancel(mAlarmSender);
            Toast.makeText(AndroidTestAlarmActivity.this, "Cancelando Alarma :(",Toast.LENGTH_SHORT).show();

        }
    };
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Button btnStart=(Button)findViewById(R.id.btnStart);
        Button btnStop=(Button)findViewById(R.id.btnStop);
        mAlarmSender = PendingIntent.getService(AndroidTestAlarmActivity.this,
                0, new Intent(AndroidTestAlarmActivity.this, Alarm.class), 0);

        btnStart.setOnClickListener(lstStart);
        btnStop.setOnClickListener(lstStop);

    }




}

我想要一些带通知的待办事项列表:)

谢谢:)
