第二种BroadcastReceiver的使用方法_actionclickmenuitem1 用法-优快云博客

本文介绍了一个基于Android的通知和广播机制实例。通过自定义广播发送和接收，实现了通知的显示和清除功能。文章详细展示了主界面Activity的实现过程，包括菜单项的创建与响应、广播Intent的发送，以及两个广播接收器的注册与通知处理。

1,主界面类的实现:

public class ActivityMain extends Activity {

public static final int ITEM0 = Menu.FIRST;
public static final int ITEM1 = Menu.FIRST + 1;

static final String ACTION_1 = "com.eoeandroid.action.NEW_BROADCAST_1";
static final String ACTION_2 = "com.eoeandroid.action.NEW_BROADCAST_2";

@Override
protected void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.main);

}

public boolean onCreateOptionsMenu(Menu menu) {
  super.onCreateOptionsMenu(menu);
  menu.add(0, ITEM0, 0, "显示Notification");
  menu.add(0, ITEM1, 0, "清除Notification");
  menu.findItem(ITEM1);
  return true;
}

public boolean onOptionsItemSelected(MenuItem item) {
  switch (item.getItemId()) {
  case ITEM0:
   actionClickMenuItem1();
   break;
  case ITEM1:
   actionClickMenuItem2();
   break;

}
return true;
}

private void actionClickMenuItem1() {
Intent intent = new Intent(ACTION_1);//生成Intent对象参数为action（自定义的）
sendBroadcast(intent);//广播Intent
}

private void actionClickMenuItem2() {
Intent intent = new Intent(ACTION_2);
sendBroadcast(intent);

}

2.在AndroidManifest.xml的application 中注册:

3，负责2种广播接收类

一:

public class EoeAndroidReceiver1 extends BroadcastReceiver {
Context context;
public static int NOTIFICATION_ID = 21321;

@Override
public void onReceive(Context context, Intent intent) {
this.context = context;
showNotification();
}

private void showNotification() {

  NotificationManager notificationManager = (NotificationManager) context
    .getSystemService(android.content.Context.NOTIFICATION_SERVICE);
  Notification notification = new Notification(R.drawable.icon,
    "在EoeAndroidReceiver1中", System.currentTimeMillis());

  PendingIntent contentIntent = PendingIntent.getActivity(context, 0,
    new Intent(context, ActivityMain.class), 0);
  notification.setLatestEventInfo(context, "在EoeAndroidReceiver1中", null,
    contentIntent);
  notificationManager.notify(NOTIFICATION_ID, notification);
}
}

二:

import android.app.NotificationManager;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;

public class EoeAndroidReceiver2 extends BroadcastReceiver {
Context context;

@Override
public void onReceive(Context context, Intent intent) {
  // TODO Auto-generated method stub
  this.context = context;
  DeleteNotification();
}

private void DeleteNotification() {

  NotificationManager notificationManager = (NotificationManager) context
    .getSystemService(android.content.Context.NOTIFICATION_SERVICE);
  notificationManager.cancel(EoeAndroidReceiver1.NOTIFICATION_ID);

}

}
