public class MainActivity extends Activity { TextView setTime1; TextView setTime2; TextView setTime3; Button mButton1; Button mButton2; Button mButton3; Button mButton4; Button mButton5; Button mButton6;  String time1String = null; String time2String = null; String time3String = null; String defalutString = "目前无设置";  AlertDialog builder = null; Calendar c=Calendar.getInstance();  @Override public void onCreate(Bundle savedInstanceState) {  super.onCreate(savedInstanceState);

    editor.putString("TIME1", tmpS);     editor.commit();          Toast.makeText(MainActivity.this,"设置大明闹钟时间为"+tmpS,     Toast.LENGTH_SHORT)     .show();    }       },mHour,mMinute,true).show();   }  }); }  public void InitButton2() {  mButton2=(Button) findViewById(R.id.mButton2);  mButton2.setOnClickListener(new View.OnClickListener()  {   public void onClick(View v)   {   Intent intent = new Intent(MainActivity.this, CallAlarm.class);   PendingIntent sender=PendingIntent.getBroadcast(    MainActivity.this,0, intent, 0);   AlarmManager am;   am =(AlarmManager)getSystemService(ALARM_SERVICE);   am.cancel(sender);   Toast.makeText(MainActivity.this,"大明闹钟时间删除",       Toast.LENGTH_SHORT).show();   setTime1.setText("目前无设置");      SharedPreferences time1Share = getPreferences(0);    SharedPreferences.Editor editor = time1Share.edit();    editor.putString("TIME1", "目前无设置");    editor.commit();   }  });

}  public void InitButton4() {  mButton4=(Button) findViewById(R.id.mButton6);  mButton4.setOnClickListener(new View.OnClickListener()  {   public void onClick(View v)   {   Intent intent = new Intent(MainActivity.this, CallAlarm.class);   PendingIntent sender=PendingIntent.getBroadcast(    MainActivity.this,0, intent, 0);   AlarmManager am;   am =(AlarmManager)getSystemService(ALARM_SERVICE);   am.cancel(sender);   Toast.makeText(MainActivity.this,"大明闹钟时间删除",       Toast.LENGTH_SHORT).show();   setTime3.setText("目前无设置");      //SharedPreferences保存数据，并提交    SharedPreferences time2Share = getPreferences(1);    SharedPreferences.Editor editor = time2Share.edit();    editor.putString("TIME2", "目前无设置");    editor.commit();   }  }); }  public void InitButton5() {  setTime2=(TextView) findViewById(R.id.setTime2);  LayoutInflater factory = LayoutInflater.from(this);  final View setView = factory.inflate(R.layout.timeset,null);  final TimePicker tPicker=(TimePicker)setView         .findViewById(R.id.tPicker);  tPicker.setIs24HourView(true);   final AlertDialog di=new AlertDialog.Builder(MainActivity.this)    .setIcon(R.drawable.clock)    .setTitle("设置")    .setView(setView)    .setPositiveButton("确定",    new DialogInterface.OnClickListener()    {    public void onClick(DialogInterface dialog, int which)    {     EditText ed=(EditText)setView.findViewById(R.id.mEdit);     int times=Integer.parseInt(ed.getText().toString())        *1000;     c.setTimeInMillis(System.currentTimeMillis());     c.set(Calendar.HOUR_OF_DAY,tPicker.getCurrentHour());     c.set(Calendar.MINUTE,tPicker.getCurrentMinute());     c.set(Calendar.SECOND,0);     c.set(Calendar.MILLISECOND,0);      Intent intent = new Intent(MainActivity.this,            CallAlarm.class);     PendingIntent sender = PendingIntent.getBroadcast(     MainActivity.this,1, intent, 0);     AlarmManager am;     am = (AlarmManager)getSystemService(ALARM_SERVICE);     am.setRepeating(AlarmManager.RTC_WAKEUP,       c.getTimeInMillis(),times,sender);     String tmpS=format(tPicker.getCurrentHour())+"："+        format(tPicker.getCurrentMinute());     String subStr = "设置大明闹钟时间为"+tmpS+       "开始，重复间隔为"+times/1000+"秒";     setTime2.setText("设置大明闹钟时间为"+tmpS+         "开始，重复间隔为"+times/1000+"秒");          //SharedPreferences保存数据，并提交      SharedPreferences time3Share = getPreferences(2);    SharedPreferences.Editor editor = time3Share.edit();    editor.putString("TIME3", subStr);    editor.commit();          Toast.makeText(MainActivity.this,"设置大明闹钟为"+tmpS+         "开始，重复间隔为"+times/1000+"秒",         Toast.LENGTH_SHORT).show();    }    })    .setNegativeButton("取消",    new DialogInterface.OnClickListener()    {    public void onClick(DialogInterface dialog, int which)    {    }    }).create();   mButton5=(Button) findViewById(R.id.mButton3);  mButton5.setOnClickListener(new View.OnClickListener()  {   public void onClick(View v)   {   c.setTimeInMillis(System.currentTimeMillis());   tPicker.setCurrentHour(c.get(Calendar.HOUR_OF_DAY));   tPicker.setCurrentMinute(c.get(Calendar.MINUTE));   di.show();   }  }); }  public void InitButton6() {  mButton6=(Button) findViewById(R.id.mButton4);  mButton6.setOnClickListener(new View.OnClickListener()  {   public void onClick(View v)   {   Intent intent = new Intent(MainActivity.this, CallAlarm.class);

 }  })  .setNegativeButton("取消",  new DialogInterface.OnClickListener() {  public void onClick(DialogInterface dialog,   int whichButton) {   builder.dismiss();  }  }).show();   }   return true; }  private String format(int x) {  String s=""+x;  if(s.length()==1) s="0"+s;  return s; }}

二、CallAlarm中的代码：

package com.cn.daming; import android.content.Context;import android.content.Intent;import android.content.BroadcastReceiver;import android.os.Bundle; public class CallAlarm extends BroadcastReceiver{ @Override public void onReceive(Context context, Intent intent) { Intent i = new Intent(context, AlarmAlert.class);   Bundle bundleRet = new Bundle(); bundleRet.putString("STR_CALLER", ""); i.putExtras(bundleRet); i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); context.startActivity(i); }}

三、AlarmAlert中的代码：

package com.cn.daming; import android.app.Activity;import android.app.AlertDialog;import android.content.DialogInterface;import android.os.Bundle; public class AlarmAlert extends Activity{ @Override protected void onCreate(Bundle savedInstanceState)  { super.onCreate(savedInstanceState); new AlertDialog.Builder(AlarmAlert.this)  .setIcon(R.drawable.clock)  .setTitle("大明闹钟响了!!")  .setMessage("快完成你制定的计划吧!!!")  .setPositiveButton("关掉它",   new DialogInterface.OnClickListener()  {   public void onClick(DialogInterface dialog, int whichButton)   {   AlarmAlert.this.finish();   }  })  .show(); } }

四、main.xml布局文件的代码：
