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; /** * com.Aina.Android * Pro_AlarmManager * @author Aina.huang E-mail: 674023920@qq.com * @version 创建时间：2010 Jul 8, 2010 3:03:19 PM * 类说明 */ 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"); } }); } } <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <TextView android:layout_width="fill_parent" android:id="@+id/TextView" android:layout_height="wrap_content" android:text="@string/hello" /> <Button android:text="设置闹钟" android:id="@+id/Button01" android:layout_width="wrap_content" android:layout_height="wrap_content"> </Button> <Button android:text="取消闹钟" android:id="@+id/Button02" android:layout_width="wrap_content" android:layout_height="wrap_content"> </Button> </LinearLayout>
