Android transition from Textview to Edittext

Question

Android transition from Textview to Edittext

I have this strange error in my android app. I have one activity with a recycler view and some elements in it (in my case, there are school subjects, four textViews and one framelayout). When you click on an element, it will navigate to the shared elements and you will enter EditActivity

where you can edit the theme. After the completion of the transistor, the text in editText

moved up. The text only becomes normal when you click editText

, I don't know why. Sometimes the text looks fine. Perhaps this is because I am doing a transition from textView

(in item) to editText

(in EditActitvty). Please advise. This is my code.

SubjectActivity.java

with RecyclerView:

@Override
protected void onCreate(Bundle savedInstanceState) {
    if (Learn.sdk21()) {
        //To enable window content transitions in your code instead, call the Window.requestFeature() method:
        getWindow().requestFeature(android.view.Window.FEATURE_CONTENT_TRANSITIONS);
        Transition ts_enter = new Explode();   //Slide(); //Explode();
        Transition ts_exit = new ChangeBounds();

        ts_enter.setDuration(Learn.animationTime);
        ts_exit.setDuration(Learn.animationTime);
    /*
    If you have set an enter transition for the second activity,
    the transition is also activated when the activity starts.
    */
        getWindow().setEnterTransition(ts_enter);
        getWindow().setExitTransition(ts_exit);
    }
    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_subject);
