}

二、CallAlarm中的代码：

package ;

import t;

import ;

import astReceiver;

import ;

public class CallAlarm extends BroadcastReceiver

{

@Override

public void onReceive(Context context, Intent intent)

{

Intent i = new Intent(context, );

Bundle bundleRet = new Bundle();

ing("STR_CALLER", "");

ras(bundleRet);

gs(_ACTIVITY_NEW_TASK);

ctivity(i);

}

三、AlarmAlert中的代码：

package ;

import ty;

import ialog;

import Interface;

import ;

public class AlarmAlert extends Activity

{

@Override

protected void onCreate(Bundle savedInstanceState)

{

te(savedInstanceState);

new r()

.setIcon()

.setTitle("大明闹钟响了!!")

.setMessage("快完成你制定的计划吧")

.setPositiveButton("关掉它",

new kListener()

{

public void onClick(DialogInterface dialog, int whichButton)

{

();

}

})

.show();

}
