Android编程使用AlarmManager设置闹钟的方法

本文实例讲述了Android编程使用AlarmManager设置闹钟的方法。分享给大家供大家参考，具体如下：

package com.Aina.Android;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.widget.Toast;

public class AlamrReceiver extends BroadcastReceiver {
  @Override
  public void onReceive(Context context, Intent intent) {
    // TODO Auto-generated method stub
    Toast.makeText(context, "闹钟时间到", Toast.LENGTH_LONG).show();
  }
}

package com.Aina.Android;
import java.util.Calendar;
import android.app.Activity;
import android.app.AlarmManager;
import android.app.PendingIntent;
import android.app.TimePickerDialog;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
import android.widget.TimePicker;
public class Test extends Activity {
  
  private TextView tv = null;
  private Button btn_set = null;
  private Button btn_cel = null;
  private Calendar c = null;
  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    tv = (TextView) this.findViewById(R.id.TextView);
    btn_set = (Button) this.findViewById(R.id.Button01);
    btn_cel = (Button) this.findViewById(R.id.Button02);
    c = Calendar.getInstance();
    btn_set.setonClickListener(new Button.onClickListener(){
      public void onClick(View v) {
 // TODO Auto-generated method stub
 c.setTimeInMillis(System.currentTimeMillis());
 int hour = c.get(Calendar.HOUR_OF_DAY);
 int minute = c.get(Calendar.MINUTE);
 new TimePickerDialog(Test.this,new TimePickerDialog.onTimeSetListener(){
   public void onTimeSet(TimePicker view, int hourOfDay,
int minute) {
     // TODO Auto-generated method stub
     c.setTimeInMillis(System.currentTimeMillis());
     c.set(Calendar.HOUR_OF_DAY, hourOfDay);
     c.set(Calendar.MINUTE, minute);
     c.set(Calendar.SECOND, 0);
     c.set(Calendar.MILLISECOND, 0);
     Intent intent = new Intent(Test.this,AlamrReceiver.class);
     PendingIntent pi = PendingIntent.getBroadcast(Test.this, 0, intent, 0);
     AlarmManager am = (AlarmManager) getSystemService(Activity.ALARM_SERVICE);
     am.set(AlarmManager.RTC_WAKEUP, c.getTimeInMillis(), pi);//设置闹钟
     am.setRepeating(AlarmManager.RTC_WAKEUP, c.getTimeInMillis(), (10*1000), pi);//重复设置
     tv.setText("设置的闹钟时间为："+hourOfDay+":"+minute);
   }
 },hour,minute,true).show();
      }
    });
    btn_cel.setonClickListener(new Button.onClickListener(){
      public void onClick(View v) {
 // TODO Auto-generated method stub
 Intent intent = new Intent(Test.this,AlamrReceiver.class);
 PendingIntent pi = PendingIntent.getBroadcast(Test.this, 0, intent, 0);
 AlarmManager am = (AlarmManager) getSystemService(Activity.ALARM_SERVICE);
 am.cancel(pi);
 tv.setText("闹钟取消");
      }
    });
  }
}
