Spinner with fragment and MySQL database

Spinner with fragment and MySQL database - android

This is the output image:
Currently I am working with a project of registration form. In that I used four Spinner and three edit text, but when I run the project the app is not getting in a correct order and when varying screen size the form is also changing. I want the app in a correct order and supported for all screen size. I used Fragment but that also is not working.

Please remove the fixed size of text views and edit texts and use weight to get responsive design.
I make sure you will get layout or design according to your expectations.
if you need code then I can code also but you need to go through first because you will learn it.

How to change a lot of textview to scrolled list layout

I'm begginer in programming and i need your help. I have to write application which will be display sensor results as text, and i did it in wrong way (code is working, but when screen is not scrolling).
Below i copy XML file:

I tried use ArrayString, listAdapter but i had always a lot of errors.. please help

you need to use a scrollview , just insert your XML contents inside this before the and it should work:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<ScrollView
android:id="#+id/scrollView1"
android:layout_width="match_parent"
android:layout_height="match_parent" >
</ScrollView>
</LinearLayout>

i guess it's because i'm loading a lot of views...
I'm also wanna to add a progress bar that works while the layout is loading until its done.
how can i fix that?
thanks :)

Multiplechoice in AlertDialog

I use "lv_del_transl.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE)" to set this options.
code to create AlertDialog:
