Scale imageview on tablet with original aspect

I have the code below and I face a problem with the image view "#+id/logo_skilfull" because it does not keep the aspect.. I think is because of the scaleType or the adjustViewBounds..
image in tablet
image in a phone (I want this)

You should read about the ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
This is a problem changing the size of the View. You need to set scaleType.
Try fitStart.
<ImageView
android:id="#+id/logo_skilfull"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:layout_gravity="center"
android:layout_marginLeft="10dp"
android:layout_marginTop="10dp"
android:background="#drawable/logos"
android:scaleType="fitStart"
android:layout_alignParentBottom="true" />

Why don't you try to hide it?
You can try to detect the keyboard state with this :
final View activityRootView = findViewById(R.id.activityRoot);
activityRootView.getViewTreeObserver().addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
#Override
public void onGlobalLayout() {
int heightDiff = activityRootView.getRootView().getHeight() - activityRootView.getHeight();
if (heightDiff > 100) { // if more than 100 pixels, its probably a keyboard...
... do something here
}
}
});
Note : Taken from here
And then you just hide the view that you want to hide.

Try with
android:windowSoftInputMode="adjustPan"
in the Activity declaration in the manifest

LinearLayout on android

I was trying to create a sign up form for my Android application
This is my XML code
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center_horizontal"
android:orientation="horizontal" >
<TextView
android:id="#+id/mynumber"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Number +961"
android:textSize="20sp"
android:color="#android:color/white" />
<EditText
android:id="#+id/editTextNumber"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:hint="Number"
android:textColor="#FFFFFF" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center_vertical"
android:orientation="vertical" >
<Button
android:id="#+id/buttonCreateAccount"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_marginBottom="60dp"
android:background="#drawable/ic_create" />
</LinearLayout>
</LinearLayout>
If you notice the first LinearLayout has a horizontal orientation and gravity (I want both the textview and edit text to be next to each others)
After the first linear layout i want the create account button to come out
However it is showing up on the same line with the previous edit text and text view
Any idea if i should change in the settings of the second linear layout

Change it like this
<LinearLayout
android:gravity="center_horizontal"
android:layout_height="match_parent"
android:layout_width="match_parent"
android:orientation="vertical">
<LinearLayout
android:gravity="center_vertical"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:orientation="horizontal">
<TextView
android:color="#android:color/white"
android:id="#+id/mynumber"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:text="Number +961"
android:textSize="20sp" />
<EditText
android:hint="Number"
android:id="#+id/editTextNumber"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:textColor="#FFFFFF" />
</LinearLayout>
<Button
android:background="#drawable/ic_create"
android:id="#+id/buttonCreateAccount"
android:layout_height="wrap_content"
android:layout_marginBottom="60dp"
android:layout_width="fill_parent" />
</LinearLayout>

Try Below Xml File
Use Relative layout Or One MAin LinearLayout with Vertical Orientation and in sub take Horizontal as you required.
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center_vertical"

Change your layout type;
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center_horizontal"
android:orientation="vertical" >

Definitely. What your are doing is encapsulating the second LinearLayout inside the first LinearLayout, that dictates a horizontal layout, ultimately resulting in horizontal positioning of all three components. Your hierarchy is as follows:
LinearLayout-Horizontal[TextView + EditText + LinearLayout-Vertical[Button]]
When supplying a LinearLayout with an orientation parameter, you're telling it to arrange all its children in that manner.
What I would recommend to you, to achieve the desired look is either:
Use a RelativeLayout (http://developer.android.com/guide/topics/ui/layout/relative.html) and position the elements in relation to each other and their parent.
Nest several LinearLayouts(not a recommended practice; here it wouldn't prove an issue but in larger and more complex layouts nesting too many such components may ultimately result in long rendering time for your view). This solution is pretty similar to what you have now and would work as follows:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center_horizontal"
android:orientation="vertical" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center_vertical"
android:orientation="horizontal" >
<TextView
android:id="#+id/mynumber"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Number +961"
android:textSize="20sp"
android:color="#android:color/white" />
<EditText
android:id="#+id/editTextNumber"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:hint="Number"
android:textColor="#FFFFFF" />
</LinearLayout>
<Button
android:id="#+id/buttonCreateAccount"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_marginBottom="60dp"
android:background="#drawable/ic_create" />
</LinearLayout>
Here you tell your outer layout to position its children vertically, where one of its children is a LinearLayout that positions its children horizontally, resulting in:
[[TEXT][EDIT]]
[ BUTTON ]
Hope this helps.

Scaling issue in a RadioButton with text

Basically, this gives the following UI
Now the problem is, the RadioButtons with text in the first column of the table takes only 40% of the available width. But, I need them to take 75% of the available width, and the things in second column can get the rest.
How can I do this?

Try this..
