EditText loses focus when typing in it

Question

I added a bunch of EditTexts programatically to a scrollview. When the keyboard shows up it resize the views, including the scrollview, and some of the edittexts get covered by it, no problem , I just scroll to find them. The problem comes when I type in any of the edittexts, the focus is lost, to be clear the view is still focused but out of the visible range. It's like typing in it would resize again the scrollview before the keyboard showed up and therefore, the view is realocated. I already look for solutions in the web, but nobody seems to have this issue.

Note: android:windowSoftInputMode="adjustPan" won't do the trick

Any idea of what is happening ? or what can I do?

Here is some of the code:

 for (int i = 1; i <= number_of_edittexts; ++i) {
  editText = new EditText(this);
        editText.setInputType(1);
        editText.setImeOptions(6);
        editText.setHint("Example: aeiou");
        editText.setY(heightET);
        editText.setX(widthET);
        editText.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
        layout.addView(editText);
        heightTV = heightTV + 100;
        heightET = heightET + 100;
   }

Here is the XML:

因此，而不是设置与所述视图的高度setY(int)我用setMaxHeight(int)
