FragmentTransaction commit multiple tasks is not work

I have two fragments in my activity. When I switch fragment use the code:
private void switchCourseFragment() {
if (mCourseFragment == null || getActivity().isFinishing()) return;
FragmentTransaction mTransaction = mFragmentManager.beginTransaction();
if (mFragmentLogin != null && mFragmentLogin.isAdded()) {
mTransaction.remove(mFragmentLogin);
}
if (!mCourseFragment.isAdded()) {
mTransaction.add(R.id.learncenter_contain, mCourseFragment).commitAllowingStateLoss();
}
}
But this is not what I expected. The mFragmentLogin is not been removed, but the mCourseFragment is been added.

You have to commit for it to take effect.
private void switchCourseFragment() {
if (mCourseFragment == null || getActivity().isFinishing()) return;
if (mFragmentLogin != null && mFragmentLogin.isAdded()) {
mFragmentManager.beginTransaction().remove(mFragmentLogin).commit();
}
if (!mCourseFragment.isAdded()) {
mFragmentManager.beginTransaction().add(R.id.learncenter_contain, mCourseFragment).commitAllowingStateLoss();
}
}
but why don't you use replace instead?
private void switchCourseFragment() {
if (mCourseFragment == null || getActivity().isFinishing()) return;
if (!mCourseFragment.isAdded()) {
mFragmentManager.beginTransaction().replace(R.id.learncenter_contain, mCourseFragment).commitAllowingStateLoss();
}
}
This assume that both your fragments are in the same container.

Difference between getWindow().setBackgroundDrawable and getWindow().getDecorView().setBackgroundDrawable

What is the difference between them? As far as I can see they both do the same thing.

If you go to sources, you will find PhoneWindow.class that have implementation of Window.setBackgroundDrawable method:
#Override
public final void setBackgroundDrawable(Drawable drawable) {
if (drawable != mBackgroundDrawable || mBackgroundResource != 0) {
mBackgroundResource = 0;
mBackgroundDrawable = drawable;
if (mDecor != null) {
mDecor.setWindowBackground(drawable);
}
if (mBackgroundFallbackResource != 0) {
mDecor.setBackgroundFallback(drawable != null ? 0 : mBackgroundFallbackResource);
}
}
}
As you can see, it calls different method of DecorView setWindowBackground:
public void setWindowBackground(Drawable drawable) {
if (getBackground() != drawable) {
setBackgroundDrawable(drawable);
if (drawable != null) {
drawable.getPadding(mBackgroundPadding);
} else {
mBackgroundPadding.setEmpty();
}
drawableChanged();
}
}
Which is actually use method DecorView.setBackgroundDrawable but also provides additional logic for Window. So I would suggest you to use getWindow().setBackgroundDrawable().

Android - Why the click event isn't trigged

I'm facing a problem with the focus on my application. I'm trying to catch the click event to animate my edittext, but for a reason I don't understand, sometimes my edittext is focused but the click event is not trigged.
The user has to click a 2nd time to start the animation.
I've got 2 AutocompleteTextView in my SherlockFragment.
Is it possible that come from the animation I'm doing ?
Edit:
mEtWhere.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Log.d(TAG, "mEtWhere've been clicked");
if (!mllWhereHasBeenClicked) {
mllWhereHasBeenClicked = true;
if (mAlphaFrameLayout != null) {
animate(mAlphaFrameLayout).setDuration(ANIM_DURATION / 2).alpha(0.9f);
}
if (mllWhere != null) {
oldllWhereYpos = ViewHelper.getY(mllWhere);
Log.v(TAG, "OldYWhereLLpos: " + oldllWhereYpos);
animate(mllWhere).setDuration(ANIM_DURATION).y(25.0f);
mBringToFrontView(mllWhere);
}
}
}
});
This is the code to reset the position of all my edittexts
private void resetPositionViews() {
closeKeyBoard();
if (mAlphaFrameLayout != null && ViewHelper.getAlpha(mAlphaFrameLayout) > 0.0f) {
animate(mAlphaFrameLayout).setDuration((7 / 4) * ANIM_DURATION).alpha(0.0f);
mBringToFrontView(mAlphaFrameLayout);
}
if (ViewHelper.getY(mllWho) == 25.0f && mEtWho.isFocused() && mllWhoHasBeenClicked) {
Log.i(TAG, "mEtWho has the focus");
Log.i(TAG, "Back to oldllWhoYpos: " + oldllWhoYpos);
animate(mllWho).setDuration(ANIM_DURATION).y(oldllWhoYpos);
mllWhoHasBeenClicked = false;
}
if (ViewHelper.getY(mllWhere) == 25.0f && mEtWhere.isFocused() && mllWhereHasBeenClicked) {
Log.i(TAG, "mEtWho has the focus");
Log.i(TAG, "Back to oldllWhoYpos: " + oldllWhereYpos);
animate(mllWhere).setDuration(ANIM_DURATION).y(oldllWhereYpos);
mllWhereHasBeenClicked = false;
}
}

Ideas to refactor code with many Lists

I need a little help to get an idea of how to refactor my code, but I can't see options besides what's done, I would like to add the objects but not using so many lists (and if's conditions).
Here is my code, if anyone could help, I appreciate. Thanks
#ViewById
BannerHomeViewPager place1, place2, place3, place4, place5, place6, place7,
place8, place9;
The lists:
private List<HomeItem> allHomeItems = new ArrayList<HomeItem>(),
placeItems1 = new ArrayList<HomeItem>(),
placeItems2 = new ArrayList<HomeItem>(),
placeItems3 = new ArrayList<HomeItem>(),
placeItems4 = new ArrayList<HomeItem>(),
placeItems5 = new ArrayList<HomeItem>(),
placeItems6 = new ArrayList<HomeItem>(),
placeItems7 = new ArrayList<HomeItem>(),
placeItems8 = new ArrayList<HomeItem>(),
placeItems9 = new ArrayList<HomeItem>();
1) Items mocked, ok.
2)
#UiThread
void updateUI() {
if (allHomeItems != null && allHomeItems.size() > 0) {
for (HomeItem item : allHomeItems) {
if (item.getPlacement().contains("1")) {
placeItems1.add(item);
} else if (item.getPlacement().contains("2")) {
placeItems2.add(item);
} else if (item.getPlacement().contains("3")) {
placeItems3.add(item);
} else if (item.getPlacement().contains("4")) {
placeItems4.add(item);
} else if (item.getPlacement().contains("5")) {
placeItems5.add(item);
} else if (item.getPlacement().contains("6")) {
placeItems6.add(item);
} else if (item.getPlacement().contains("7")) {
placeItems7.add(item);
} else if (item.getPlacement().contains("8")) {
placeItems8.add(item);
} else {
placeItems9.add(item);
}
}
}
setupAdapters();
}
3) setupAdapters()
private void setupAdapters() {
if (place1 != null)
place1.update(placeItems1);
if (place2 != null)
place2.update(placeItems2);
if (place3 != null)
place3.update(placeItems3);
if (place4 != null)
place4.update(placeItems4);
if (place5 != null)
place5.update(placeItems5);
if (place6 != null)
place6.update(placeItems6);
if (place7 != null)
place7.update(placeItems7);
if (place8 != null)
place8.update(placeItems8);
if (place9 != null)
place9.update(placeItems9);
}

As #DanielBo answer:
private Map<String, ArrayList<HomeItem>> placeItems = new HashMap<String,ArrayList<HomeItem>>();
void updateUI() {
if (allHomeItems != null && allHomeItems.size() > 0) {
for (HomeItem item : allHomeItems) {
if(!placeItems.containsKey(item.getPlacement())){
placeItems.put(item.getPlacement(), new ArrayList<HomeItem>());
}
placeItems.get(item.getPlacement()).add(item);
}
}
setupAdapters();
}
But why are you using so many views? I really can't say if this is correct bcs i don't know the purpose of this, but I can't figure a good use to so many list views in the same layout...

Chromecast SDK (Android) - is there a way to check whether the media playing on the cast device has finished playing?

Is there an onFinished listener of some sort? Or do we have to compare the current stream position against the duration of the track?

It's not pretty but you can make this call:
if (mRemoteMediaPlayer.getMediaStatus().getPlayerState() == MediaStatus.PLAYER_STATE_IDLE
&& mRemoteMediaPlayer.getMediaStatus().getIdleReason() == MediaStatus.IDLE_REASON_FINISHED) {
...
}

Prem,
There is currently no callback to register for such event. One alternative (and-not-so-pretty) approach is the following: on the receiver, listen for "ended" event of the media element and send an event back to the sender through a private channel. Another approach is what you suggested: check position against duration. When SDK graduates to general availability, better and cleaner approaches will be available to accomplish what you want.

Here is solution:
You just need to take one more variable mIdleReason.
1) Initialize mIdleReason as
public int mIdleReason=MediaStatus.IDLE_REASON_NONE;
2) Update value at method loadMedia
public void loadMedia(String url, MediaMetadata movieMetadata, CastSession castSession, boolean autoPlay, long position) {
if (castSession == null || !castSession.isConnected()) {
return;
}
MediaInfo mediaInfo = new MediaInfo.Builder(url)
.setStreamType(MediaInfo.STREAM_TYPE_BUFFERED)
.setContentType("videos/m3u8")
.setMetadata(movieMetadata)
.build();
mRemoteMediaClient = castSession.getRemoteMediaClient();
mRemoteMediaClient.addListener(mRemoteMediaClientListener);
mRemoteMediaClient.load(mediaInfo, autoPlay, position);
mIdleReason = MediaStatus.IDLE_REASON_NONE;
}
3) Update value at onStatusUpdate:
private RemoteMediaClient.Listener mRemoteMediaClientListener = new RemoteMediaClient.Listener() {
#Override
public void onStatusUpdated() {
if (mRemoteMediaClient == null || mediaPlayerListener == null) {
return;
}
MediaStatus mediaStatus = mRemoteMediaClient.getMediaStatus();
if (mediaStatus != null) {
int playerStatus = mediaStatus.getPlayerState();
Log.d("PlayerState", "onStatusUpdated() called, progress= "+mSeekBar.getProgress() +", stream duration= "+ mRemoteMediaClient.getStreamDuration()+" mSeekBar.getProgress() == mRemoteMediaClient.getStreamDuration()="+(mSeekBar.getProgress() == mRemoteMediaClient.getStreamDuration()));
Log.d("PlayerState", "onStatusUpdated() called playerStatus="+playerStatus+", idleReason="+mediaStatus.getIdleReason());
if (playerStatus == MediaStatus.PLAYER_STATE_PLAYING) {
mediaPlayerListener.playing();
mIdleReason = MediaStatus.IDLE_REASON_FINISHED;
} else if (playerStatus == MediaStatus.PLAYER_STATE_BUFFERING) {
mediaPlayerListener.buffering();
mIdleReason = MediaStatus.IDLE_REASON_FINISHED;
} else if (playerStatus == MediaStatus.PLAYER_STATE_PAUSED) {
mediaPlayerListener.paused();
} else if (playerStatus == MediaStatus.IDLE_REASON_INTERRUPTED) {
mediaPlayerListener.error();
} else if (playerStatus == MediaStatus.IDLE_REASON_ERROR) {
mediaPlayerListener.error();
}else if(playerStatus == MediaStatus.PLAYER_STATE_IDLE && mediaStatus.getIdleReason() == MediaStatus.IDLE_REASON_FINISHED&& mIdleReason == MediaStatus.IDLE_REASON_FINISHED){
mediaPlayerListener.played();
}
}
}
#Override
public void onMetadataUpdated() {
Log.d("", "onMetadataUpdated: ");
}

public void onQueueStatusUpdated() {
