android - 开机后仍可收听电话状态

在我的应用程序中，我使用Broadcast Receiver收听电话状态事件（即呼叫已接收，空闲等）。代码如下：

public class PhoneCallreceiver extends BroadcastReceiver {
    private boolean ringing;
    private boolean received;

    public PhoneCallreceiver() {
    }

@Override
public void onReceive(Context context, Intent intent) {
    Log.v("ranjith", "enterted receiver");
    Bundle bundle = intent.getExtras();
    String incomingnumber = bundle.getString(TelephonyManager.EXTRA_INCOMING_NUMBER);
    String state = bundle.getString(TelephonyManager.EXTRA_STATE);
    Log.v("ranjapp", state);

    if (state.equals(TelephonyManager.EXTRA_STATE_RINGING)) {
        ringing = true;
        received = false;
    }
}

Manifest.xml

    <receiver
        android:name=".PhoneCallreceiver"
        android:enabled="true">
        <intent-filter>
            <action android:name="android.intent.action.PHONE_STATE"/>
        </intent-filter>
    </receiver>

我的问题是设备重新引导后我想自动启动BroadCast Receiver。我有一个BroadCast Receiver听启动，但是我不确定如何启动PhoneCallreceiver BroadCast接收器。

Manifest.xml

   <receiver
        android:name=".backend.BootStarter"
        android:enabled="true">
        <intent-filter>
            <action android:name="android.intent.action.BOOT_COMPLETED"/>
        </intent-filter>
    </receiver>

码：

public class BootStarter extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        PhoneCallreceiver callreceiver = new PhoneCallreceiver();
        context.registerReceiver(callreceiver,new IntentFilter(**what to put here**));
            }
        }

最佳答案

找到了我的问题的答案，接收电话状态的intentfilter动作是android.telephony.TelephonyManager.ACTION_PHONE_STATE_CHANGED

我的更新代码如下：

public class BootStarter extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
    PhoneCallreceiver callreceiver = new PhoneCallreceiver();
            context.registerReceiver(new PhoneCallreceiver(), new IntentFilter(android.telephony.TelephonyManager.ACTION_PHONE_STATE_CHANGED));
        }
    }
