Android 从广播接收器调用活动中的方法

这是我的广播接收器类，我想在我的main活动中调用一个方法（重新连接（）；），同时显示“连接丢失！尝试重新连接…”吐司

导入android.content.BroadcastReceiver；
导入android.content.Context；
导入android.content.Intent；
导入android.net.ConnectivityManager；
导入android.net.NetworkInfo；
导入android.widget.Toast；
公共类连接StablizerReceiver扩展BroadcastReceiver{
@凌驾
公共void onReceive（上下文、意图）{
if（isConnected（context））Toast.makeText（context，“Connection builded！”，Toast.LENGTH_SHORT.show（）；
else Toast.makeText（上下文，“连接丢失！尝试重新连接…”），Toast.LENGTH_LONG.show（）；
}
公共布尔值未连接（上下文）{
连接管理器cm=
（ConnectionManager）context.getSystemService（context.CONNECTIVITY_服务）；
NetworkInfo activeNetwork=cm.getActiveNetworkInfo（）；
布尔值isConnected=activeNetwork！=null&&
activeNetwork.isConnected（）；
返回不连接；
}
}

创建ConnectionsTablezerReceiver类作为活动的内部类。；它会起作用的

public class Splash_screen extends Activity {  
     private static int SPLASH_TIME_OUT = 4000;
    Global global;
    SharedPreferences pref;
    String base_url_final="";
    private static  String checkurlonetag ="sdfasdf";
    private static  String checkurltwotag ="sdfasdfgsdfhsfdhasdf";




//   Dbhelper dbhelper;
    @Override

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_splash_screen);
        global= (Global) getApplicationContext();


    }


    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.splash_screen, menu);
        return true;
    } 





    class ConnectionStablizerReceiver extends  BroadcastReceiver{


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


//dont forget to register reciver permision

if(intent.getAction().equals("android.net.conn.CONNECTIVITY_CHANGE")){
            //do your onreceive action
        }



        }
    }

}

改用EventBus库来解耦代码！检查此项。使用不同的操作从广播接收器发送广播，该操作将在活动中接收广播接收器。广播接收器内部正确的方法现在有什么问题？请将您的清单放在此处并记录

public class Splash_screen extends Activity {  
     private static int SPLASH_TIME_OUT = 4000;
    Global global;
    SharedPreferences pref;
    String base_url_final="";
    private static  String checkurlonetag ="sdfasdf";
    private static  String checkurltwotag ="sdfasdfgsdfhsfdhasdf";




//   Dbhelper dbhelper;
    @Override

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_splash_screen);
        global= (Global) getApplicationContext();


    }


    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.splash_screen, menu);
        return true;
    } 





    class ConnectionStablizerReceiver extends  BroadcastReceiver{


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


//dont forget to register reciver permision

if(intent.getAction().equals("android.net.conn.CONNECTIVITY_CHANGE")){
            //do your onreceive action
        }



        }
    }

}
