I'm currently making an app where I want an imageview on top of the screen (with a gap of 10% of the screen from top) and a table under the imageview with 4 buttons in it.
What I have right now is:
<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"
android:background="@drawable/testhback"
android:gravity="bottom" >
<ImageView
android:id="@+id/imageView1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginBottom="@dimen/f1"
android:adjustViewBounds="true"
android:src="@drawable/img1" />
<TableLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="@dimen/top2"
android:stretchColumns="*" >
<TableRow
android:id="@+id/tableRow1"
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<Button
android:id="@+id/button5"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_below="@+id/button4"
android:onClick="changepic2"
android:text="Breaking Dawn" />
<Button
android:id="@+id/button4"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBaseline="@+id/button1"
android:layout_alignBottom="@+id/button1"
android:layout_alignLeft="@+id/button5"
android:layout_alignParentRight="true"
android:onClick="changepic3"
android:text="New Moon (2)" />
</TableRow>
<TableRow
android:id="@+id/tableRow3"
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<Button
android:id="@+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_above="@+id/button3"
android:layout_alignParentLeft="true"
android:onClick="changepic"
android:text="Twilight (1)" />
<Button
android:id="@+id/button3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:onClick="changepic1"
android:text="Eclipse (3)" />
</TableRow>
</TableLayout>
The problem is that I've tried to set margins from the top for the table. But on each screen it looks different, and I didn't figure out how to tell it to automatically take, let's say, 10% for top line under it, 70% for the imageview, and 20% for the table with 4 button in it at the bottom.
