Android app not showing complete Samsung S3 mini

I'm new to android and working on my first app which is from a online course project. The fact is that on Android Studio the app is working fine, but I built the apk file to test it on my phone (Samsung galaxy s3 mini). On device, the app is not showing complete as it is missing an edit text and a button at the bottom of the layout. I'm attaching two screenshots, the first one of the app running on the emulator, and the one running on my smartphone.
App running in the emulator:
App running on the smartphone:

put your xml code within of a ScrolView:
<ScrollView
android:layout_height="match_parent"
android:fillViewport="true"
android:layout_width="match_parent"
xmlns:android="http://schemas.android.com/apk/res/android" >
your xml
</ScrollView>
or add weight at your layouts:
<LinearLayout
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1">

As you see I used ScrollView, but scrolling a view would be enabled ONLY if a device would not have enough space to take everything on its screen.
In the other case it would be like any other static layout.
It doesn't mean that you would scroll it on every device or your game would be less attractive ;-)
Also you can change height of your picture to wrap_content, bu I suppose that author if this tutorial make this height by value, because the picture in the reality is much bigger than that with height of 350dp.

Layout doesn't fill frame layout in android 2.3

I have a FrameLayout with two LinearLayouts inside. For Android version 4.x it works fine but for version 2.3 second LinearLayout doesn't fill FrameLayout vertically. Can anyone tell me why? Btw I know I set second LinearLayout as invisible but I show it up later in code :)

How to design a xml file to display in more screen

I'm new android programmer, I designed a page screen of 4". I've initialized with "dp" unit of measurement.
but when I run my project in screen of 10" or 7" or 3"2 components go wrong.
I learned dp is for all of screen, but I don't know why my page not be set to all of screens.

If you could include any code of your XML file, that would be very helpful.
Aside from that, I believe you haven't set android:layout_width and android:layout_height so you are getting odd looking sizes for the other display sizes of you XML.
Add
android:layout_width="match_parent"
android:layout_height="match_parent"
to your <RelativeLayout>
e.g.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
...

If you do in fact have this or it does not help with your issue
, then please respond with an example of your code.

my xml file is here, but I set visibility of one linearlayout to gone
and when user touch button the linearlayout will be visible and another linearlayout will be gone

Kindly advise what's wrong with this layout because I have set all width to match parent but still not working in all device.
Really appreciate for any kind help.

Hmm, I cant see anything wrong right now.
One time I had a problem that anything on my code was wrong, but on devices running API 18+ the android:gravity="center_vertical" simple did not work, but I fix it just changing the value of android:target="18" to android:target="16". I choose "16" because it was the version of my Android that was running without any problems.
I don't know if this is your case, but change the android target property at Android Manifest.xml, just give it a try (y)

TextView contents not centering correctly on android 4.2.2

The image on the right (2.3.3) presents my view as i would like it to, however i can't get it to look right on 4.2.2. Notice how the text in the textview is not vertically centered. I've tried both in the emulator and on Galaxy S4. Also, the eclipse ADT preview of XML files shows it centered correctly.
The view is used in a listview.
How do i center the text in my textview so it looks the same on all android versions?

You should to remove android:layout_alignBottom and android:layout_alignTop attributes.

Well, i solved my issue by wrapping the textview in a linearlayout which centers the textview via gravity.
There seems to be a bug where you can't match_parent on textview within a listview on 4.2.2 (i've not tested any other versions than 4.2.2 and 2.3.3)
