Android的廣播Receiver動(dòng)態(tài)注冊(cè)和靜態(tài)注冊(cè)示例

更新時(shí)間：2017年02月25日 14:41:26 作者：dmfrm

本篇文章主要介紹了Android的廣播Receiver動(dòng)態(tài)注冊(cè)和靜態(tài)注冊(cè)示例，小編覺得挺不錯(cuò)的，現(xiàn)在分享給大家，也給大家做個(gè)參考。一起跟隨小編過來看看吧

廣播接收器注冊(cè)一共有兩種形式 : 靜態(tài)注冊(cè)和動(dòng)態(tài)注冊(cè).

兩者及其接收廣播的區(qū)別:

1.動(dòng)態(tài)注冊(cè)的廣播永遠(yuǎn)要快于靜態(tài)注冊(cè)的廣播,不管靜態(tài)注冊(cè)的優(yōu)先級(jí)設(shè)置的多高,不管動(dòng)態(tài)注冊(cè)的優(yōu)先級(jí)有多低。

2.動(dòng)態(tài)注冊(cè)廣播不是常駐型廣播，也就是說廣播跟隨activity的生命周期。注意: 在activity結(jié)束前，移除廣播接收器。

靜態(tài)注冊(cè)是常駐型，也就是說當(dāng)應(yīng)用程序關(guān)閉后，如果有信息廣播來，程序也會(huì)被系統(tǒng)調(diào)用自動(dòng)運(yùn)行。

3.在同一個(gè)優(yōu)先級(jí)下,誰先啟動(dòng)的快,誰將先接收到廣播。

下面這個(gè)Demo，界面如下，注冊(cè)兩個(gè)動(dòng)態(tài)接收器（接收自定義廣播和系統(tǒng)廣播）和注冊(cè)靜態(tài)廣播（接收自定義靜態(tài)和廣播、手機(jī)USB的插拔事件、接收短信并讀取短信息）

工程目錄如下：注意看代碼中的注釋

xml布局文件（activity_main.xml）

<?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"> 
 
 <Button 
   android:id="@+id/send_static" 
   android:layout_width="wrap_content" 
   android:layout_height="wrap_content" 
   android:text="發(fā)送自定義靜態(tài)注冊(cè)廣播"/> 
 
 <Button android:id="@+id/send_dynamic" 
   android:layout_width="wrap_content" 
   android:layout_height="wrap_content" 
   android:text="發(fā)送自定義動(dòng)態(tài)注冊(cè)廣播"/> 
 
 <Button 
   android:id="@+id/send_system" 
   android:layout_width="wrap_content" 
   android:layout_height="wrap_content" 
   android:text="發(fā)送系統(tǒng)動(dòng)態(tài)注冊(cè)廣播"/> 
 
</LinearLayout>

Manifest.xml如下，這里面定義的權(quán)限信息和注冊(cè)的廣播
