android鬧鐘——原代碼

8手機(jī)當(dāng)中肯定是有鬧鐘的，這是不用說(shuō)的，要不然就不是手機(jī)了。對(duì)吧。
下面我根據(jù)廣播的方式寫(xiě)了一個(gè)鬧鐘，大家請(qǐng)看圖：

下面讓我們看一下原代碼的是如何寫(xiě)的，
package com.smart;

import java.util.Calendar;

import android.app.Activity;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.SharedPreferences;
import android.media.MediaPlayer;

public class AlarmReceiver extends BroadcastReceiver {
/**
* 通過(guò)廣播進(jìn)行掃描，是否到達(dá)時(shí)間后再響起鬧鈴
*
* */
@Override
public void onReceive(Context context, Intent intent) {


      SharedPreferences sharedPreferences=context.getSharedPreferences("alarm_record", Activity.MODE_PRIVATE);
      String hour=String.valueOf(Calendar.getInstance().get(Calendar.HOUR_OF_DAY));
      String minute=String.valueOf(Calendar.getInstance().get(Calendar.MINUTE));
      String time=sharedPreferences.getString(hour+":"+minute, null);//小時(shí)與分，

      if(time!=null){//判斷是否為空，然后通過(guò)創(chuàng)建，
         MediaPlayer mediaPlayer=MediaPlayer.create(context, R.raw.llb);
         mediaPlayer.start();//開(kāi)始
      }

}

}
package com.smart;

import android.app.Activity;
import android.app.AlarmManager;
import android.app.AlertDialog;
import android.app.PendingIntent;
import android.content.Context;
import android.content.DialogInterface;
import android.content.Intent;
import android.content.SharedPreferences;
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 Main extends Activity implements OnClickListener{

private TextView alarmRecord;
private SharedPreferences sharedPreferences;


@Override
public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.main);
      Button addAlarm=(Button)findViewById(R.id.addAlarm);
      alarmRecord=(TextView)findViewById(R.id.alarmRecord);
      addAlarm.setOnClickListener(this);
      sharedPreferences=getSharedPreferences("alarm_record", Activity.MODE_PRIVATE);
      AlarmManager aManager=(AlarmManager)getSystemService(Context.ALARM_SERVICE);
      Intent intent=new Intent(this,AlarmReceiver.class);
      PendingIntent pendingIntent=PendingIntent.getBroadcast(this, 0, intent, 0);
      aManager.setRepeating(AlarmManager.RTC, 0, 60*1000, pendingIntent);

}


@Override
public void onClick(View v) {
      View view=getLayoutInflater().inflate(R.layout.llb, null);//
      final TimePicker timePicker=(TimePicker)view.findViewById(R.id.timepicker);
      timePicker.setIs24HourView(true);//
      new AlertDialog.Builder(this).setTitle("設(shè)置鬧鈴時(shí)間").setView(view).setPositiveButton("確定", new DialogInterface.OnClickListener() {
         //設(shè)置標(biāo)題
         @Override
         public void onClick(DialogInterface dialog, int which) {
         //按鈕事件觸發(fā)方法
            String timeStr=String.valueOf(timePicker.getCurrentHour())+":"+String.valueOf(timePicker.getCurrentMinute());
            alarmRecord.setText(alarmRecord.getText().toString()+"
"+timeStr);
            sharedPreferences.edit().putString(timeStr, timeStr).commit();

         }
      }).setNegativeButton("取消", null).show();
}
