问题
So to tell you exactly what's going on, let me explain the context first.
I followed this tutorial : https://viksaaskool.wordpress.com/2014/11/16/using-auto-resize-to-fit-edittext-in-android/
which is basically a simple autoresizeEditText, based on the autoFitTextView library ( https://github.com/grantland/android-autofittextview ).
What I want to achieve : When I click on a button, the entire layout is zoomed in, and I simulate a click on the editText to let the user enter some text.
What I have been achieving so far : well, pretty much everything, excepts that it only works on some devices, and not on others.
FYI, here are two animated gifs that'll illustrate what I'm talking about :
GOOD BEHAVIOUR(Nexus 5 API 21) : http://giphy.com/gifs/xTiTnH1hyuJzjnDl6w
BAD BEHAVIOUR(Nexus 6 API 22) : http://giphy.com/gifs/3-1-2-3o85xDB4Wyve1jh0XK
As you can see, zooming is fine, then entering text is fine until, in some cases, the text won't appear after what seems to be the right-hand-side of the unzoomed editText. But as soon as the text size has to be changed (or I zoom out the views), everything goes back to normal.
So my question : anyone would have an idea of what could make this strange behaviour? Anyone encountered this problem, either on the autoFitTextView or an extension of it?
Thanks in advance!
PS : I could post some code, but as both libraries + links are provided and are pretty long, I prefer not posting them here, as they're basically the same. What I can provide though is the calls made to animate the views and show the keyboard (even if I'm not sure it's related) :
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
mView = inflater.inflate(R.layout.add_message_layout, null);
mMessageEditText = (AutoResizeEditText) mView.findViewById(R.id.messageEditText);
mMessageEditText.setEnabled(false);
mMessageEditText.setEnableSizeCache(false);
mMessageEditText.setMovementMethod(null);
mMessageEditText.setInterface(this);
mMessageEditText.setMinTextSize(TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_SP, MIN_SP_TEXT_SIZE, getResources().getDisplayMetrics()));
mMessageEditText.setMaxHeight((int) DisplayUtils.convertDpToPixel(getActivity().getApplicationContext(), mMessageEditText.getMeasuredHeight()));
mMessageEditText.setLines(MAX_LINES_COUNT);
mMessageEditText.addTextChangedListener(new TextWatcher() {
@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
mLastMessage = mMessageEditText.getText().toString();
}
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
if (mMessageEditText.getLineCount() > MAX_LINES_COUNT) {
//If user tries to type more text than expected !
mMessageEditText.setText(mLastMessage);
mMessageEditText.setSelection(mLastMessage.length());
Toast.makeText(getActivity().getApplicationContext(), "Limit Reached", Toast.LENGTH_SHORT).show();
}
}
@Override
public void afterTextChanged(Editable s) {
mLastMessage = mMessageEditText.getText().toString();
mMessageEditText.invalidate();
}
});
mAddMessageButton = (RelativeLayout) mView.findViewById(R.id.rlAddMessage);
mAddMessageButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
setupAnimations();
animZoomIn();
}
});
mCardLayout = (LinearLayout) mView.findViewById(R.id.rearMainCardLayout);
return (mView);
}
private void setupAnimations() {
mPivotX = mMessageEditText.getPivotX() / mCardLayout.getMeasuredHeight();
mPivotY = mMessageEditText.getPivotY() / mCardLayout.getMeasuredWidth();
mZoomIn = new ScaleAnimation(1.0f, 1.3f, 1.0f, 1.3f, mPivotX, mPivotY);
mZoomIn.setDuration(1000);
mZoomIn.setFillAfter(true);
mSlideUp = new TranslateAnimation(0.0f, 100.0f, 0.0f, -100.0f);
mSlideUp.setDuration(1000);
mSlideUp.setFillAfter(true);
mEnterAnimation = new AnimationSet(true);
mEnterAnimation.setInterpolator(new LinearInterpolator());
mEnterAnimation.addAnimation(mZoomIn);
mEnterAnimation.addAnimation(mSlideUp);
mEnterAnimation.setFillAfter(true);
mEnterAnimation.setAnimationListener(new Animation.AnimationListener() {
@Override
public void onAnimationStart(Animation animation) {
mBeginX = mMessageEditText.getLeft();
mBeginY = mMessageEditText.getTop();
}
@Override
public void onAnimationEnd(Animation animation) {
mMessageEditText.setPressed(true); //EditText will get highlighted
mMessageEditText.setFocusable(true);
mMessageEditText.setFocusableInTouchMode(true);
mMessageEditText.setTextIsSelectable(true);
mMessageEditText.requestFocus();
mMessageEditText.invalidate();
mMessageEditText.setEnabled(true);
showKeyboard(getActivity().getApplicationContext(), mMessageEditText);
}
@Override
public void onAnimationRepeat(Animation animation) {}
});
mZoomOut = new ScaleAnimation(1.3f, 1.0f, 1.3f, 1.0f, mPivotX, mPivotY);
mZoomOut.setDuration(1000);
mZoomOut.setFillAfter(true);
mSlideDown = new TranslateAnimation(100.0f, 0.0f, -100.0f, 0.0f);
mSlideDown.setDuration(1000);
mSlideDown.setFillAfter(true);
mExitAnimation = new AnimationSet(true);
mExitAnimation.setInterpolator(new LinearInterpolator());
mExitAnimation.addAnimation(mZoomOut);
mExitAnimation.addAnimation(mSlideDown);
mExitAnimation.setFillAfter(true);
mExitAnimation.setAnimationListener(new Animation.AnimationListener() {
@Override
public void onAnimationStart(Animation animation) {}
@Override
public void onAnimationEnd(Animation animation) {
mMessageEditText.invalidate();
}
@Override
public void onAnimationRepeat(Animation animation) {}
});
}
private void animZoomIn() {
mCardLayout.startAnimation(mEnterAnimation);
}
private void animZoomOut() {
mCardLayout.startAnimation(mExitAnimation);
}
private static void closeKeyboard(Context c, IBinder windowToken) {
InputMethodManager manager = (InputMethodManager)c.getSystemService(Context.INPUT_METHOD_SERVICE);
manager.hideSoftInputFromWindow(windowToken, 0);
}
private static void showKeyboard(Context c, EditText text) {
InputMethodManager manager = (InputMethodManager) c.getSystemService(Context.INPUT_METHOD_SERVICE);
manager.showSoftInput(text, InputMethodManager.SHOW_IMPLICIT);
}

Okay, so thanks to @android developer who pointed out the problem, this was caused by the old version of the animations I was using.
So by replacing
mZoomOut = new ScaleAnimation(1.3f, 1.0f, 1.3f, 1.0f, mPivotX, mPivotY);
mZoomOut.setDuration(1000);
mZoomOut.setFillAfter(true);
mSlideDown = new TranslateAnimation(100.0f, 0.0f, -100.0f, 0.0f);
mSlideDown.setDuration(1000);
mSlideDown.setFillAfter(true);
mExitAnimation = new AnimationSet(true);
mExitAnimation.setInterpolator(new LinearInterpolator());
mExitAnimation.addAnimation(mZoomOut);
mExitAnimation.addAnimation(mSlideDown);
mExitAnimation.setFillAfter(true);
mExitAnimation.setAnimationListener(new Animation.AnimationListener() {
@Override
public void onAnimationStart(Animation animation) {}
@Override
public void onAnimationEnd(Animation animation) {
mMessageEditText.invalidate();
}
@Override
public void onAnimationRepeat(Animation animation) {}
});
mCardLayout.startAnimation(mEnterAnimation);
by the new ones :
mCardLayout.animate().translationX(0.0f).translationY(0.0f).scaleX(1.0f).scaleY(1.0f).setDuration(1000).withEndAction(new Runnable() {
@Override
public void run() {
mMessageEditText.invalidate();
mIsViewZoomed = false;
}
});
resolved everything.
