推荐答案

您不需要启动/停止一个BroadcastReceiver。它不是你的后台运行的服务。您只需要注册或注销其用于您的应用程序。注册后，其常开。

You don't need to start/stop a BroadcastReceiver. Its not your background running service. All you need is to register or unregister it for your application. Once registered, its always ON.

在某些特定的事件发生时，系统会通知（广播）有关该事件的所有注册应用程序。所有注册的应用程序接收到这是一个意图。此外，您可以把您自己的广播。

When some specific event occur, system notifies(broadcast) all registered applications about the event. all registered apps receives this as an Intent. Also, you can send your own broadcast.

简单的例子：

在我的表现，我包括许可和一个接收器

in my manifest, I'm including a permission and a receiver

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.android.receivercall"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="10" />
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <receiver android:name=".Main">
        <intent-filter >
            <action android:name="android.intent.action.PHONE_STATE"/>
        </intent-filter>
    </receiver>
    <activity android:name=".TelServices">
        <intent-filter >
            <action android:name="android.intent.action.MAIN"/>
            <category android:name="android.intent.category.LAUNCHER"/>

        </intent-filter>
    </activity>
</application>

现在，我的接收器， Main.java

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.telephony.TelephonyManager;
import android.widget.Toast;



   public class Main extends BroadcastReceiver {
    String number,state;   
    @Override
    public void onReceive(Context context, Intent intent) {

         state=intent.getStringExtra(TelephonyManager.EXTRA_STATE);

        if(state.equals(TelephonyManager.EXTRA_STATE_RINGING)){
            number=intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);

            Toast.makeText(context, "Call from : "+number, Toast.LENGTH_LONG).show();
        }
        else if(state.equals(TelephonyManager.EXTRA_STATE_IDLE))
            Toast.makeText(context, "Call ended", Toast.LENGTH_LONG).show();
        else
            Toast.makeText(context, intent.getAction(), Toast.LENGTH_LONG).show();

    }

}

在这里，当我安装这个程序，我通过清单注册一个BroadcastReceiver。而面包都会出现有来电/结束时间。

Here, when I install this app, I'm registering a Broadcastreceiver through manifest. And the Toast will appear every time a call comes/ends.
