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 {
  /** Called when the activity is first created. */
  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");
      }
    });
  }
}
