问题描述

我为Android应用程序制作QT.当我单击按钮时，在平板电脑中看到的栏.但是，如果单击通知，我的应用程序会打开/焦点(不知道)用黑色窗口.如何做到这一点.我的代码是:

package org.ays.operation;

import android.app.Notification;
import android.app.NotificationManager;
import android.content.Context;
import android.app.PendingIntent;
import android.content.Intent;


public class NotificationClient extends org.qtproject.qt5.android.bindings.QtActivity
{
     private static NotificationManager m_notificationManager;
     private static Notification.Builder m_builder;
     private static NotificationClient m_instance;
     private static PendingIntent contentIntent;
     private static Intent intent;


     public NotificationClient()
     {
         m_instance = this;
     }

     public static  void notify2()
     {
         intent = new Intent(m_instance, NotificationClient.class);         contentIntent = PendingIntent.getActivity(m_instance, 0, intent,
                                         PendingIntent.FLAG_UPDATE_CURRENT);

         if (m_notificationManager == null) {
             m_notificationManager = (NotificationManager)m_instance.getSystemService(Context.NOTIFICATION_SERVICE);
             m_builder = new Notification.Builder(m_instance);
             m_builder.setSmallIcon(R.drawable.icon);
             m_builder.setContentTitle("A message from Qt!");
             m_builder.setDefaults(Notification.DEFAULT_SOUND);
             m_builder.setContentIntent(contentIntent);
             m_builder.setAutoCancel(true);
         }

         m_builder.setContentText("Bla Bla");
         m_notificationManager.notify(1, m_builder.build());
     }
 }

我的客人，重要的代码正在悬而未决，可以打开/焦点主应用程序.另一种情况是，我不想将Notify2用作静态.我可以从qt/jni

中使用它的动态吗

推荐答案

第一条方法:

您必须更改此行

intent = new Intent(m_instance, NotificationClient.class);

to

Intent intent = new Intent(mActivityInstance, mActivityInstance.getClass());

和

contentIntent = PendingIntent.getActivity(m_instance, 0, intent,
                                     PendingIntent.FLAG_UPDATE_CURRENT);

to

contentIntent = PendingIntent.getActivity(mActivityInstance, 0, intent,
                                     PendingIntent.FLAG_UPDATE_CURRENT);

注意力持续性是您的主要目的.

我从C ++和JNI设置我的mactivitySinstance，如下所示:

const QAndroidJniObject m_JavaNotification("com/falsinsoft/qtandroidtools/AndroidNotification",
                   "(Landroid/app/Activity)V",
                   QtAndroid::androidActivity().object<jobject>());

和我的androidnotification.java:

public class AndroidNotification {
private final Activity mActivityInstance;

public AndroidNotification(Activity ActivityInstance)
{
    mActivityInstance = ActivityInstance;
}
}

第二种方法(我不确定这能解决您的问题！):
在您的士cipiset.xml中更改此行:

<application android:hardwareAccelerated="true" android:name="org.qtproject.qt5.android.bindings.QtApplication" android:label="YourProjectName" android:icon="@drawable/icon">

to:

<application android:hardwareAccelerated="true" android:name="your java class extend from QtActivity" android:label="YourProjectName" android:icon="@drawable/icon">
