Android – 从通知 *** 作按钮调用方法

概述我知道您可以使用PendingIntents从 *** 作按钮启动活动.如何在用户单击通知 *** 作按钮时调用方法？ public static void createNotif(Context context){ ... drivingNotifBldr = (NotificationCompat.Builder) new NotificationCompat.Builder(context) 我知道您可以使用PendingIntents从 *** 作按钮启动活动.如何在用户单击通知 *** 作按钮时调用方法？

public static voID createNotif(Context context){    ...    drivingNotifBldr = (NotificationCompat.Builder) new NotificationCompat.Builder(context)            .setSmallicon(R.drawable.steeringwheel)            .setContentTitle("NoTextZone")            .setContentText("Driving mode it ON!")            //Using this action button I would like to call logTest            .addAction(R.drawable.smallmanwalking,"Turn OFF driving mode",null)            .setongoing(true);    ...}public static voID logtest(){    Log.d("Action button","Action button Worked!");}

解决方法 单击 *** 作按钮时无法直接调用方法.

您必须使用PendingIntent与broadcastReceiver或Service来执行此 *** 作.以下是使用broadcastRecIEver的PendingIntent的示例.

首先让我们建立一个通知

public static voID createNotif(Context context){    ...    //This is the intent of PendingIntent    Intent intentAction = new Intent(context,ActionReceiver.class);    //This is optional if you have more than one buttons and want to differentiate between two    intentAction.putExtra("action","actionname");    pIntentlogin = PendingIntent.getbroadcast(context,1,intentAction,PendingIntent.FLAG_UPDATE_CURRENT);    drivingNotifBldr = (NotificationCompat.Builder) new NotificationCompat.Builder(context)            .setSmallicon(R.drawable.steeringwheel)            .setContentTitle("NoTextZone")            .setContentText("Driving mode it ON!")            //Using this action button I would like to call logTest            .addAction(R.drawable.smallmanwalking,pIntentlogin)            .setongoing(true);    ...}

现在接收器将接收此Intent

public class ActionReceiver extends broadcastReceiver {    @OverrIDe    public voID onReceive(Context context,Intent intent) {        //Toast.makeText(context,"recIEved",Toast.LENGTH_SHORT).show();        String action=intent.getStringExtra("action");        if(action.equals("action1")){            performAction1();        }        else if(action.equals("action2")){            performAction2();        }        //This is used to close the notification tray        Intent it = new Intent(Intent.ACTION_CLOSE_SYstem_DIALOGS);        context.sendbroadcast(it);    }    public voID performAction1(){    }    public voID performAction2(){    }}

在Manifest中声明广播接收器

<receiver androID:name=".ActionReceiver" />
