Android反复闹钟(每天)的实现
MainActivity例如以下:
package cc.cc; import java.util.Calendar; import java.util.Locale; import android.os.Bundle; import android.app.Activity; import android.app.AlarmManager; import android.app.PendingIntent; import android.content.Context; import android.content.Intent; /** * Demo描写叙述: * 反复闹钟的实现 * * 注意事项: * 1 由于我们是要实现的两个闹钟每天早八点和晚八点,它们是反复的. * 所以在PendingIntent.getBroadcast()非常easy出错.导致早八点 * 的闹钟无效.主要原因是由于该方法的第四个參数引起的. * 解决的方法:为BroadcastReceiver设置两个action,在生成Intent * 的时候採用了不同的action,从而让两个闹钟都起作用. * 假设有更好的方式请留言指出,多谢. * 2 在calendar.set(Calendar.HOUR_OF_DAY, 8)方法的第二个參数 * 表示小时,请依照24小时制式填写.不用管此时设备採用什么时间 * 制式(12小时或24小时) * * 參考资料: * 1 http://blog.csdn.net/hudashi/article/details/7060837 * 2 http://blog.csdn.net/wdaming1986/article/details/6745655 * 3 http://blog.csdn.net/z1074971432/article/details/17532139 * Thank you very much * */ public class MainActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); sendAlarmEveryday1(this); sendAlarmEveryday2(this); } private void sendAlarmEveryday1(Context context){ AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE); Calendar calendar =Calendar.getInstance(Locale.getDefault()); calendar.setTimeInMillis(System.currentTimeMillis()); calendar.set(Calendar.HOUR_OF_DAY, 8); calendar.set(Calendar.MINUTE, 30); calendar.set(Calendar.SECOND, 0); calendar.set(Calendar.MILLISECOND, 0); Intent intent = new Intent(); intent.setAction("testalarm0"); PendingIntent pendingIntent=PendingIntent.getBroadcast(context,0, intent,PendingIntent.FLAG_CANCEL_CURRENT); alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,calendar.getTimeInMillis(),AlarmManager.INTERVAL_DAY,pendingIntent); } private void sendAlarmEveryday2(Context context){ AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE); Calendar calendar =Calendar.getInstance(Locale.getDefault()); calendar.setTimeInMillis(System.currentTimeMillis()); calendar.set(Calendar.HOUR_OF_DAY, 20); calendar.set(Calendar.MINUTE, 30); calendar.set(Calendar.SECOND, 0); calendar.set(Calendar.MILLISECOND, 0); Intent intent = new Intent(); intent.setAction("testalarm1"); PendingIntent pendingIntent=PendingIntent.getBroadcast(context,0, intent,PendingIntent.FLAG_CANCEL_CURRENT); alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,calendar.getTimeInMillis(),AlarmManager.INTERVAL_DAY,pendingIntent); } }
AlarmBroadcastReceiver例如以下:
package cc.cc; import android.content.BroadcastReceiver; import android.content.Context; import android.content.Intent; public class AlarmBroadcastReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { if ("testalarm0".equals(intent.getAction())) { System.out.println("第一个闹钟"); } if ("testalarm1".equals(intent.getAction())) { System.out.println("第二个闹钟"); } } }
AndroidManifest.xml例如以下:
<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="cc.cc" android:versionCode="1" android:versionName="1.0" > <uses-sdk android:minSdkVersion="10" android:targetSdkVersion="10" /> <application android:allowBackup="true" android:icon="@drawable/ic_launcher" android:label="@string/app_name" android:theme="@style/AppTheme" > <activity android:name="cc.cc.MainActivity" android:label="@string/app_name" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <receiver android:name="cc.cc.AlarmBroadcastReceiver"> <intent-filter > <action android:name="testalarm0"/> <action android:name="testalarm1"/> </intent-filter> </receiver> </application> </manifest>
main.xml例如以下:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" tools:context=".MainActivity" > <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/hello_world" /> </RelativeLayout>
