Custom Android View for QCARPlayer Activity - problem

March 21, 2013 - 3:28am #1

 

Am trying to inflate my Custom UI through the below code which I found out in the forum. I Am able to successfuly inflate a android widget through the code that you had given.  But when I inflate an Layout file (Which is having just one Hello World text view and an image) the app is getting closed. Below is the LOGCAT of the app. Can you help me on this ?
 
Thank you. 
 
CODE SNIPPET:
class QCARViewFinderTask extends TimerTask {
   
  public void run() {
      Test.this.runOnUiThread(new Runnable() {
       public void run() {
          if (!QCAR.isInitialized()) return; //wait for QCAR init
                       
          if (mQCARView != null) return;//already found, no need to search
                              
          //else search
          View rootView = Test.this.findViewById(android.R.id.content);
          QCARUnityPlayer qcarView = findQCARView(rootView);
                        
          //if QCAR view has been found, add some android view/widget on top
          if (qcarView != null) {
              ViewGroup qcarParentView = (ViewGroup)(qcarView.getParent());
              /*                 
              Button button = new Button(Test.this);
              button.setText("Press me");
              button.setOnClickListener(new Button.OnClickListener() {
                @Override
                public void onClick(View v) {
                    Toast.makeText(Test.this, "Button was pressed!", Toast.LENGTH_SHORT).show();    
                }
              });
               */
              View myView = getLayoutInflater().inflate(R.layout.activity_test, null);
              qcarParentView.addView(myView, new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
              
              //qcarParentView.addView(button, new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
                        
              mQCARView = qcarView;
            }
          }
     });

If the button is visible but not "clickable", you probably need to simply set the ForwardNativeEventsToDalvik to true in your AndroidManifest.xml; see also:

have you tried using the bringToFront() method ?

i.e. myView.bringToFront() ?

If that does not work yet, then it is likely to be an issue with the Layout.

Custom Android View for QCARPlayer Activity - problem

March 22, 2013 - 3:41am #9

I meant Unity Android Plugin Approach. Through the plugin I was able to populate the Android Widget on GUI.button Click in Unity Project. 

 

//if QCAR view has been found, add some android view/widget on top
          if (qcarView != null) {
              ViewGroup qcarParentView = (ViewGroup)(qcarView.getParent());
              /*                 
              Button button = new Button(Test.this);
              button.setText("Press me");
              button.setOnClickListener(new Button.OnClickListener() {
                @Override
                public void onClick(View v) {
                    Toast.makeText(Test.this, "Button was pressed!", Toast.LENGTH_SHORT).show();    
                }
              });
               */
              View myView = getLayoutInflater().inflate(R.layout.activity_test, null);
              qcarParentView.addView(myView, new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
               
              //qcarParentView.addView(button, new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
                         
              mQCARView = qcarView;

If you note the Commented part, I used your way of inflating the Android widget. This gets triggered when I click on GUI Button in Unity. I tried to inflate my custom layout similar to the way you gave the code for android widget

Hey, when you say:

But I am able to inflate the android widgets that you had posted on the forum

Do you mean you can inlfate them using the "work from Eclipse" approach, or using the "Unity Android Plugin" approach ?

Custom Android View for QCARPlayer Activity - problem

March 22, 2013 - 2:56am #7

I tried the tutorial that you had sent me. I sucessfully integrated the Java Project and the Unity project. I was able to overlay some Image Views and Image Buttons on top of the AR view of unity.

So, what is the issue in making as an android plugin through which I inflate my XML layout objects ? But I am able to inflate the android widgets that you had posted on the forum. Please help me on this.

Thank you.

Hi, the tutorial I'm referring to shows how to do things from Eclipse (not using the "plugin" approach, which is slightly different).

I would try maybe that first (read the link that I have pasted below).

So, then you should just add those layouts (and layout directories) in your Eclipse project directory and build/run from there.

 

Yeah. I have used the above tutorial and exported the jar file from Java Project and Have put it in Assets/Plugins/Android folder of the Unity Project and updated the Androidmanifest file and working in the unity platform. 

For me everything is working in UNITY. I played a toast message on GUI.button click. But when I try to inflate an XML file from the Android plugin. It is shooting the earlier error that I had quoted. 

 

My requirement is:

1. I have an android layout XML file and a corresponding activity. 

2.  On GUI.button click from the unity screen, i should populate the activity with the UI (I dont want to programatically add layouts. Planning to use XML file)

Hey,

I created the three folders with all the available layouts as mentioned by you.  (I created these folders in my java project from which I exported the jar. Should I create some layout file in the Unity Project too ? I suppose, that should be included in the JAR file itself. )

layout-large
layout-small
layout-xlarge
 
Am getting the same error.

Custom Android View for QCARPlayer Activity - problem

Hi, this is a typical resource issue where Android cannot find your layout;

normally you should put your layout XML in the res/layout folder of your project, but you may also need to add the same layout in these three additional subdirectories:

  • res/layout-small/
  • res/layout-large/
  • res/layout-xlarge/

Have you tried that ?
