我知道您可以使用PendingIntents从操作按钮启动活动.如何在用户单击通知操作按钮时调用方法？
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
单击操作按钮时无法直接调用方法.
您必须使用PendingIntent与BroadcastReceiver或Service来执行此操作.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" />
希望能帮助到你.
