Answer 1

you can adjust it using linear layout using weight i have pasted a sample code below hope this helps.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:background="@color/transparent"
 >

 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1"
android:orientation="horizontal"
>
 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="5"
 />
 <TextView
    android:id="@+id/desiredbox"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:text="TextView"
    android:layout_gravity="center"
    android:background="@color/skyblueBackground" 
    android:layout_weight="1"
    />
 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="5"
 />
 </LinearLayout>
 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1"
/>

Answer 2

Yeah. This is possible using a Relative layout parent and another layout(your box) inside that positioned as center. and the width and height of your box can be mentioned in java, rather than in xml.
