I have discovered what I think is a bug in FragmentTabHost.java which always generates a new layout for the tabhost even if a layout is specified. See the google discussion here.
I want to override this file in my project, but I encountered errors when I imported it into my project.
Does anyone know the right way to use my own copy of FragmentTabHost.java?
you can use this class, then extend your new class with this

I'm having some troubles getting my custom listView adapter to work. I am having issue in getting the message values dynamically into the custom adapter. I have got the values dynamically but when I used that in my code, the app crashes or it displays nothing.

this.context = context;
this.values = values;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View rowView = inflater.inflate(R.layout.view, parent, false);
TextView textView = (TextView) rowView.findViewById(R.id.text);
textView.setText(values.get(position));
Linkify.addLinks(textView,Linkify.WEB_URLS);
return rowView;
}
}
In my app, I am relying on onUserLeaveHint() method when the user presses the home button, but this method is also being called when you are starting multi window mode in android 7.0 by long pressing "recents button" (which I don't want to perform same thing that I do when home button been pressed). So I want to know if there is a way to detect which is which. Cheers!
Note: onMultiWindowModeChanged() being called after onUserLeaveHint()
I think this is what you're looking for.

the FolderActivity runs on top of the MainActivty but the voice recognition in MainActivity is still active and I want the voice itself do some manipulation in the FolderActivity
Here's a few suggestions:
Have FolderActivity register a BroadcastReceiver as a listener for a certain Intent. When MainActivity wants to do something in FolderActivity, it can send a broadcast Intent which will be seen by the BroadcastReceiver in FolderActivity, which can then call the appropriate method in the `Activity.
When MainActivity wants to do something in FolderActivity, it can launch FolderActivity again using an Intent with flag Intent.FLAG_ACTIVITY_SINGLE_TOP and some "extra" that describes what FolderActivity should do. In FolderActivity override onNewIntent(), read the passed Intent parameter and use it to determine what method to call in FolderActivity. Because the Activity was launched withIntent.FLAG_ACTIVITY_SINGLE_TOP, Android won't create a new instance of the Activity, it will just callonNewIntent()` on the existing instance.
Have FolderActivity set a public static variable of type Activity to a reference to itself in onCreate(). MainActivity can then call a method on FolderActivity by doing something like FolderActivity.activityReference.doSomething()
Method 3 is not the preferred method, since you need to make sure that you set the public static variable to null in FolderActivity.onDestroy() and there are other concerns (timing issues, memory leaks, etc.) that need to be dealt with properly.
NOTE: You probably don't want to call onOptionsItemSelected() directly. This method is called by the Android framework when an options item is selected by the user. You should call directly the method that actually does something, not this framework callback method.

In this way, there are a list of videos in the playlist, each video will start automatically when the first is finished. I need to click each video in the wall for start it
You can add an onClickListener to the ImageViews in the ImageWallView.java class, something like this:
for (int col = 0; col < numberOfColumns; col++) {
for (int row = 0; row < numberOfRows; row++) {
int elementIdx = getElementIdx(col, row);
if (images[elementIdx] == null) {
ImageView thumbnail = new ImageView(context);
thumbnail.setLayoutParams(new LayoutParams(imageWidth, imageHeight));
images[elementIdx] = thumbnail;
unInitializedImages.add(elementIdx);
thumbnail.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
ImageWallView.this.context.startActivity(YouTubeIntents.createPlayVideoIntentWithOptions(
ImageWallView.this.context, (String)v.getTag(), true, false));
}
});
}
addView(images[elementIdx]);
}
}
Then you will need to add the video id as the tag in YouTubeThumbnailView in VideoWallActivity.java
Hope that helps
You can use ImageView OnClickListener as suggested in previous answer: (onSizeChanged in ImageWallView.java)
for (int col = 0; col < numberOfColumns; col++) {
for (int row = 0; row < numberOfRows; row++) {
int elementIdx = getElementIdx(col, row);
if (images[elementIdx] == null) {
ImageView thumbnail = new ImageView(context);
thumbnail.setLayoutParams(new LayoutParams(imageWidth, imageHeight));
images[elementIdx] = thumbnail;
unInitializedImages.add(elementIdx);
thumbnail.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
ImageWallView.this.context.startActivity(YouTubeIntents.createPlayVideoIntentWithOptions(
ImageWallView.this.context, (String)v.getTag(), true, false));
}
});
}
addView(images[elementIdx]);
}
}
Then you need to store video id to the calling view of ImageWallView . (set and get tag is also used to store objects between views).
To get the child view of ImageWallView, use imageWallView.getChildAt(index). index is the position of ImageView which is clicked on ImageWallView. to get this index, use getElementIdx(col,row). You need to make this method public in ImageWallView.java.
EDITED
To use the Video ID of current thumbnail, Store the VideoID in onFlipped event. This is because onThumbnailLoaded the VideoID of next thumbnail available which immediately get Flipped and available on IamgeWallView. As VideoID is not available in onFlipped event, use it from onThumbnailLoaded event
Here it is:
Declare below string in class
private String strThumbnailVideoId;
set VideoID in onThumbnailLoaded event (in VideoWallActivity.java) into strThumbnailVideoId. This video ID will be of next thumbnail which will be flipped.
#Override
public void onThumbnailLoaded(YouTubeThumbnailView thumbnail, String videoId) {
nextThumbnailLoaded = true;
strThumbnailVideoId = videoId;
if (activityResumed) {
if (state.equals(State.LOADING_THUMBNAILS)) {
flipNext();
} else if (state.equals(State.VIDEO_FLIPPED_OUT)) {
// load player with the video of the next thumbnail being flipped in
state = State.VIDEO_LOADING;
player.cueVideo(videoId);
}
}
}
Now set the strThumbnailVideoId in onFlipped as a ImageWallView tag.
#Override
public void onFlipped(FlippingView view) {
imageWallView.showImage(flippingCol, flippingRow);
flippingView.setVisibility(View.INVISIBLE);
imageWallView.getChildAt(imageWallView.getElementIdx(flippingCol, flippingRow)).setTag(strThumbnailVideoId);
......

What's wrong? How can I fix it? I'm using IntelliJ IDEA 12 CE. Thanks a lot for any help!
This can be resolved by recreating the R.java file.
1. Re-build OR
2. Change the 'android:id' in XML file to a new id and re-build. Make sure you manually change all references to this id.
Sometimes this does´t work even recreating the R.java file, cleaning and rebuilding the project.
for me it works until i delete \gen and \bin folders, then automatically were recreated with the new relationship between resources and their id´s.
I think the problem is just that the inflater cast your item to RelativeLayout and you can't cast a relativeLayout in your item (Maybe this post is more precise : ClassCastException). Perhaps you have to give up and retrieve your object using your id with findViewById.
