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");
}
});
}
}
