廣播的類型主要分為5類：

普通廣播（Normal Broadcast）
系統(tǒng)廣播（System Broadcast）
有序廣播（Ordered Broadcast）
粘性廣播（Sticky Broadcast）
App應(yīng)用內(nèi)廣播（Local Broadcast）

發(fā)送普通廣播使用步驟

①自定義一個關(guān)播接收者繼承BroadcastReceivre
②注冊 靜態(tài)注冊 動態(tài)注冊
③通過intent發(fā)送廣播

• 靜態(tài)注冊 在在AndroidManifest.xml里通過<receive>標(biāo)簽聲明

<receiver android:name=".StaticalReceiver">
            <intent-filter>
                <action android:name="com.example.broadcastreceiver.StaticalReceiver"/>
            </intent-filter>
        </receiver>

• 動態(tài)注冊 在onResume調(diào)用 registerReceiver方法

@Override
    protected void onResume() {
        super.onResume();
        //獲取廣播接收者的對象
        dynamicReceiver = new DynamicReceiver();
        //添加intentFilter
        IntentFilter intentFilter = new IntentFilter();
        intentFilter.addAction("com.example.broadcastreceiver.StaticalReceiver");

        //注冊廣播 
        registerReceiver(dynamicReceiver, intentFilter);
    }

    @Override
    protected void onPause() {
        super.onPause();
        //銷毀廣播
        unregisterReceiver(dynamicReceiver);
    }

2. 順序廣播

①動態(tài)注冊
②通過intentFilter.setPriority();決定接收廣播的先后順序
③銷毀廣播

private void order() {
        Intent intent = new Intent("com.example.broadcastreceiver.StaticalReceiver");
        sendOrderedBroadcast(intent, null);
    }

3. 本地廣播

//注冊應(yīng)用內(nèi)廣播接收器
//步驟1：實例化BroadcastReceiver子類 & IntentFilter mBroadcastReceiver 
localReceiver= new LocalReceiver(); 
IntentFilter intentFilter = new IntentFilter(); 

//步驟2：實例化LocalBroadcastManager的實例
localBroadcastManager = LocalBroadcastManager.getInstance(this);

//步驟3：設(shè)置接收廣播的類型 
intentFilter.addAction("com.example.broadcastreceiver.LocalReceiver");

//步驟4：調(diào)用LocalBroadcastManager單一實例的registerReceiver（）方法進行動態(tài)注冊 
localBroadcastManager.registerReceiver(localReceiver, intentFilter);

//取消注冊應(yīng)用內(nèi)廣播接收器
localBroadcastManager.unregisterReceiver(localReceiver);

//發(fā)送應(yīng)用內(nèi)廣播
Intent intent = new Intent();
intent.setAction("com.example.broadcastreceiver.LocalReceiver");
localBroadcastManager.sendBroadcast(intent);
