Question

我尝试使用ImageButton创建自定义通知。当onclicked时，ImageButton应该启动一个名为TaskActivity的活动，但是我无法实现这一点。

以下是我的代码：

MainActivity.java

public void onCreate（Bundle savedInstanceState）{

    //button intents
    Intent cmdIntent = new Intent(
                       MainActivity.this, cmdButtonListener.class);
    PendingIntent pendingSwitchIntent = PendingIntent.getBroadcast(
                                        MainActivity.this, 0, cmdIntent, 0);

    //notification mgr
    int notifyID = 001;
    String ns = Context.NOTIFICATION_SERVICE;
    NotificationManager mNotifyMgr = (NotificationManager)getSystemService(ns);

    //new notification
    int icon = R.drawable.icon3;
    long when = System.currentTimeMillis();
    @SuppressWarnings({ "deprecation" })
    Notification notify = new Notification(icon,getString(R.string.text),when);

    //remote views
    RemoteViews contentView = new RemoteViews(getPackageName(),R.layout.custom_notification);
    contentView.setImageViewResource(R.id.notification_image, R.drawable.icon4);
    contentView.setTextViewText(R.id.notification_title, "APP TITLE");
    contentView.setTextViewText(R.id.notification_text, "hello");
    contentView.setOnClickPendingIntent(R.id.notification_image, pendingSwitchIntent);
    notify.contentView = contentView; //set

    //notification intent
    Intent nIntent = new Intent(MainActivity.this,MainActivity.class);
    PendingIntent contentIntent = PendingIntent.getActivity(this, 0, nIntent, 0);

    notify.contentIntent = contentIntent;

    mNotifyMgr.notify(notifyID,notify);

}

公共类cmdButtonListener扩展BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent){
        System.out.println("Here, I am here");
        Intent newAct = new Intent(MainActivity.this, TaskActivity.class);
        startActivity(newAct);

    }

}

Android清单

  <receiver android:name=".MainActivity$cmdButtonListener" />

我不知道，我在哪里做错了，因为我完全按照大多数在线教程中的说法进行操作。：（

最后，我找到了解决方案......

声明以下变量

private static Context mContext;

在 public void onCreate（Bundle savedInstanceState）{

中添加以下代码

mContext = this;

最后，更改公共类中的以下代码片段cmdButtonListener extends BroadcastReceiver {

Intent newAct = new Intent(MainActivity.this, TaskActivity.class);
startActivity(newAct);

要

Intent Act = new Intent(mContext,TaskActivity.class);
mContext.startActivity(Act);

ImageButton不支持自定义通知 - Android
