Please help me in this.
Thanks in advance!

Try this it will working...
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<LinearLayout

View like this

You need a relative layout. Set image alignt to right-top and set margin top appropriately.

<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<ImageView
android:id="#+id/first"
android:layout_width="fill_parent"
android:layout_height="70dp"
android:src="#drawable/firstImage" />
<ImageView
android:layout_width="20dp"
android:layout_height="20dp"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:layout_marginRight="5dp"
android:src="#drawable/middleImage" >
</ImageView>
<RelativeLayout
android:id="#+id/second"
android:layout_width="fill_parent"
android:layout_height="70dp"
android:layout_below="#id/first"
android:src="#drawable/share_over" >
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_marginBottom="20dp"
android:orientation="horizontal" >
<ImageView
android:id="#+id/YES"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/YES" />
<ImageView
android:id="#+id/NO"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/NO" />
</LinearLayout>
</RelativeLayout>
</RelativeLayout>
Divide your image TOP-MIDDLE-BOTTOM(layout). Your size looking like above but
you can change width/height size.

Android linear layout difficulties

I have a portrait xml layout file which contains a text-box which rests onto of an ImageView. This was done using a vertical linear layout. The trouble is, I have created a landscape xml layout file, but I don't know how to insert a text box above the ImageView in this particular layout file. For some reason i'm having trouble.
To summarize, I want to replicate the style I had in my portrait xml (with regards to the text-box and ImageView relationship). Pictures below should clarify exactly what I mean. Icons are covered in gray on purpose, but you get the general idea.
My Landscape xml:
<?xml version="1.0" encoding="utf-8"?>
<!-- This relative layout will center EVERYTHING within it. Do not touch this functionality. -->
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/relative_layout"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<ProgressBar
android:id="#+id/progressBar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"

Just wrap your CropImageView inside a layout, for example, a LinearLayout
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/relative_layout"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<ProgressBar
android:id="#+id/progressBar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal" >
<LinearLayout
android:layout_width="0dip"
android:layout_height="match_parent"
android:layout_weight="1"
android:orientation="vertical" >
<TextView
android:id="#+id/test"
android:layout_width="fill_parent"
android:layout_height="0dip"
android:layout_weight=".12"
android:text="Test" />
<com.edmodo.cropper.CropImageView

android:id="#+id/CropImageView"
android:layout_height="0dip"

android:layout_weight=".88"
android:gravity="center" >
</com.edmodo.cropper.CropImageView>
</LinearLayout>
<LinearLayout
android:layout_width="0dp"
android:layout_height="fill_parent"
android:layout_weight=".12"
android:gravity="center" >
<LinearLayout
android:id="#+id/linearLayout1"
android:layout_width="match_parent"
android:layout_height="match_parent"

android:src="#drawable/ic_action_rotate"
android:visibility="invisible"
tools:ignore="Suspicious0dp" />
<ImageView

android:layout_width="wrap_content"
android:layout_height="0dp"

The android layout lacks proportion when I set the background of Imagebutton.

The android layout lacks proportion when I set the background of Imagebutton.
And the code of xml is like the following:

How to setup can make the top of LinearLayout no deformation like the LinearLayout of bottom ?

Have you tried changing all the android:layout_height values from match_parent to wrap_content?

i think you should use scaleType to get your image look nice
prefer fitXY
like that
android:scaleType="fitXY"
put inside your xml to be whole code like that
<ImageButton
android:id="#+id/photo_record_mode"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="4"
android:background="#drawable/turn_to_photomode"
android:scaleType="fitXY"/>

3 layouts - middle is flexible

I need the following thing:
3 layouts:
Header
Content
Footer
Header must be on the top footer must be sticked to the bottom (android:layout_alignParentBottom="true").
But how to make middle to occupy the whole other screen? Thanks.

Here is my solution (with android:layout_weight and ScrollView):
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:background="#DDDDDD"
android:gravity="center"
android:orientation="vertical" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Header"
tools:ignore="HardcodedText" />
</LinearLayout>
<ScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="3" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="Content"
tools:ignore="HardcodedText" />
</ScrollView>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:background="#DDDDDD"
android:gravity="center"
android:orientation="vertical" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Footer"
tools:ignore="HardcodedText" />
</LinearLayout></LinearLayout>
And the result picture :

Hi Use the following lines
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<LinearLayout
android:id="#+id/button1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:text="Button" >
<Button
android:id="#+id/button2"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Header" />
</LinearLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_above="#+id/linearfooter"
android:layout_below="#+id/button1"
android:background="#android:color/darker_gray"
>
</LinearLayout>
<LinearLayout
android:id="#+id/linearfooter"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:text="Button" >
<Button
android:id="#+id/button2"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="footer" />
</LinearLayout>
</RelativeLayout>
hope this helps you.

Use a height of 0dp and
android:layout_weight
set to 1

Finally I've got the next solution:
To the middle layout I added:
<LinearLayout
android:id="#+id/linearLayout1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="#id/footer"
android:layout_below="#id/header"
android:layout_weight="1">
And it works!

Aligning Buttons Dynamically - Android

I am trying to make my button centered horizontally and 2/3 down from the top vertically. I want it to remain 2/3 from the top no matter what the screen size/density. Here is the button I am trying to move:
<Button
android:id="#+id/btnResume"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_marginTop="250dp" />
Thanks!
Working Code:
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<FrameLayout
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight="1" >
</FrameLayout>
<Button
android:id="#+id/btnResume"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center" />
<FrameLayout
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight="1" >
</FrameLayout>
<TextView
android:id="#+id/tvCounter2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center" />
<FrameLayout
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight="1" >
</FrameLayout>
</LinearLayout>

To archive this you need to use LineareLayout and explore weight feature. To get it work it must be something like this:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<FrameLayout
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight="1" >
</FrameLayout>
<FrameLayout
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight="1" >
</FrameLayout>
<Button
android:id="#+id/btnResume"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true" />
<FrameLayout
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight="1" >
</FrameLayout>
</LinearLayout>
Hope it helps!

You can use the attribute "layout_weight"
