1.设置布局：notification.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="horizontal" >
<ImageView
android:src="@drawable/icon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical" >
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="QQ音乐播放器" />
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="模仿音乐播放器" />
</LinearLayout>
</LinearLayout>
2.封装Notification:BaseActivity.java
package com.anjoyo.notificationM;
import android.app.Activity;
import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.widget.RemoteViews;
import android.widget.TextView;
import com.anjoyu.activity.Qq_muiceActivity;
import com.anjoyu.second.R;
public class BaseActivity extends Activity {
/**
* 封装notification类，并且主线程activit必须继承本类
*
* */
private NotificationManager manager;//为，标题栏管理方法，设置 Notification的发通知
private static final int NOTIFY_ID = 1;
private Notification notificy;//具体为标题栏的对象，可以设置文字，图片，声音，震动等...
private Context context = this;
TextView title;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// 后台运行
manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificy = new Notification(R.drawable.icon, "正在跳转",
System.currentTimeMillis());
notificy.flags = Notification.FLAG_AUTO_CANCEL
| Notification.FLAG_ONGOING_EVENT | Notification.DEFAULT_SOUND;
// PendingIntent (点击通知执行页面跳转)
PendingIntent contenIntent = PendingIntent.getActivity(context, 1,
new Intent(context, Qq_muiceActivity.class),
PendingIntent.FLAG_UPDATE_CURRENT);
notificy.setLatestEventInfo(context, "hello", "QQ音乐",//后台界面设置
contenIntent);
}
public void settitle() {
}
// onResume事件
protected void onResume() {
super.onResume();
manager.cancel(NOTIFY_ID);
}
// onPause事件
protected void onPause() {
manager.notify(NOTIFY_ID, notificy);
super.onPause();
}
}
3.主类必须继承封装类：qq_musicActivity extends BaseActivity
4.在主线程中设置返回键问题：
//notification 在返回键的操作
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_BACK) {
moveTaskToBack(true);
return true;
}
return super.onKeyDown(keyCode, event);
}
