广播接收器如何开始新意图 [英] BroadcastReceiver how to start new intent

问题描述

我实现了一个广播接收器，以块我的应用程序，如果互联网连接丢失。
通过块我的意思是应用程序有打开一个没有网络连接的活动。

这是我的接收器code：

 公共类ConnectivityReceiver扩展广播接收器{@覆盖
公共无效的onReceive（上下文的背景下，意图意图）{    布尔noConnectivity = intent.getBooleanExtra（ConnectivityManager.EXTRA_NO_CONNECTIVITY，FALSE）;
    Log.d（**调试**，noConnectivity+ noConnectivity）;    如果（noConnectivity）{
        //显示没有互联网连接活动
    }
}
}
 

难道不可能性开始NoInternetConnection.class时noConnectivity ==真??

谢谢！

解决方案：

 意向书I =新意图（背景下，NoInternetConnection.class）;
i.addFlags（Intent.FLAG_ACTIVITY_NEW_TASK）;
context.startActivity（ⅰ）;
 

解决方案

您应该只需要调用startActivity：

  context.startActivity（新意图（NoInternetConnection.class））;
 

您将需要确保NoInternetConnection活动在您的清单文件注册：

 ＆LT;活动机器人：名字=。NoInternetConnection＆GT;＆LT; /活性GT;
 

什么问题你具体有？

I implemented a broadcast receiver to "block" my app if the internet connection is lost. By block I mean that the app has to open a "No internet connection" activity.

this is my receiver code:

public class ConnectivityReceiver extends BroadcastReceiver {

@Override
public void onReceive(Context context, Intent intent) {

    boolean noConnectivity = intent.getBooleanExtra(ConnectivityManager.EXTRA_NO_CONNECTIVITY, false);
    Log.d("** Debug **","noConnectivity " + noConnectivity);

    if(noConnectivity){
        //SHOW NO INTERNET CONNECTION ACTIVITY
    }
}
}

Is it possibile to start NoInternetConnection.class when noConnectivity == true??

Thanks!

SOLUTION:

Intent i = new Intent(context, NoInternetConnection.class);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(i);

解决方案

You should just have to call startActivity:

context.startActivity(new Intent(NoInternetConnection.class));

You will need to make sure the "NoInternetConnection" activity is registered in your manifest file:

<activity android:name=".NoInternetConnection"></activity>
