Variant from android-autofittextview library : sca

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.
