Problems changing layout when clicking the Android button

Like the picture above I hope the keyboard disappears when you click the button and the layout changes like in the picture.

Version is api19 and

for the activity in the manifest By writing android:windowSoftInputMode="justResize", the layout can be changed depending on the presence or absence of the keyboard (i.e., button bars can be on the button as shown in the picture above).

And Inside the onClick

InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);

imm.hideSoftInputFromWindow(writeEt.getWindowToken(), 0);```

I wrote it like this so that the keyboard can hide.


But I don't know how to fill the layout crying
