i have used this code for my Linearlayout, As soon as i touch radioButton or edittext or i scrolldown, It start lagging alot. Im not able to understand the problem, the images i have used are small size below 100kb

I edited your code and took out about 4 LinearLayouts which were unnecessary. Please test it for performance. If it still is slow try substituting some of the remaining vertical LinearLayouts with RelativeLayouts as #IshitaShinha suggested.

As much as possible i want to stick with the listview because i'm not familiar with the recyclerview. if theres any way to fix this, i would be glad.
Check the image for the reference of my problem.
There's actually 4 items in the list and i can only view 2 items.

Firstly there is problem with your XML as when you use weightsum and layout_weight then you need not give dimensions in height or width.
This must be your XML.
Also I checked your XML there is some problem in you XML attributes too. Like you used "android:layout_below="#+id/id"" but in your xml there is no "id"

Add your java code if you are not getting 4 values into your ListView

Change you xml to :
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent"
android:weightSum="1">
<RelativeLayout
android:orientation="vertical"
android:id="#+id/border"
android:layout_width="match_parent"
android:layout_height="280dp"
android:layout_weight="0.07"--> Delete this
>
....
</RelativeLayout>
<LinearLayout
android:layout_width="match_parent"
android:orientation="horizontal"
android:layout_weight="1" -> Add this
android:layout_height="0dp" >
<ListView
android:id="#+id/listView"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
</LinearLayout>

when keyboard is open layout should move above in android

I want to move my layout above when keyboard is on. I have tried with android:windowSoftInputMode="adjustPan|adjustResize". But this is not working.
When I click on EditText it should move above so that the TextView should be visible.

Add the line below to the activity this layout is inflated in. (AndroidManifest.xml) android:windowSoftInputMode="stateUnchanged|adjustPan"

EditText disapear if layout_width="wrap_content" and not layout_weight="1"

The next code is OK for Eclipse Layout Editor and Android Studio. I tested it in several mobiles and works fine but, in a Samsung GT-S6310N (Android 4.1.2), this EditText dissapears. It goes at the end of a LinearLayout that defines the Layout width. The Layout is showed in a Dialog using android:Theme.Dialog.
<EditText
android:id="#+id/et_clino"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:ems="4"
android:inputType="numberDecimal"
android:text="89.9" />
I've solved this changing the code to:
<EditText
android:id="#+id/et_clino"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:ems="4"
android:inputType="numberDecimal"
android:text="89.9" />
The question is: is wrong mi code or is a bug?

The reason for disappearing of the EditText is that you want to display items, which has total width greater than the width of the screen, so I've applied same layout_weight:"1" to all the elements inside the LinearLayout. May be this helps you for solving your issue.

view the two buttons side by side

I have two buttons Login and Scan. I want these buttons to be in a horizontal way just like in a single row. I tied making the layout horizontal. However it does not work. They should appear side by side. My code is as follows.

Just put both button in LinearLayout whose orientation must be horizontal

Simple use this..
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<Button
android:id="#+id/textView"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_gravity="left|center"
android:layout_weight="1"
android:text="Login"
android:textColor="#000000" />
<Button
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_gravity="right"
android:layout_weight="1"
android:text="Scan"
android:textColor="#000000" />
</LinearLayout>
</LinearLayout>

Use this code:
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_marginTop="5dp"
/>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/imagesand"
android:gravity="center"
android:orientation="vertical" >
<LinearLayout
android:layout_width="207dp"
android:layout_height="wrap_content"
android:layout_marginLeft="40dp"
android:layout_marginRight="40dp"
android:background="#drawable/loginbg"
android:gravity="center"
android:orientation="vertical"
android:layout_alignParentBottom="true"
android:paddingLeft="20dp"
android:paddingRight="20dp" >
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:text="User Name"
android:textAppearance="#android:style/TextAppearance.Medium" />
<EditText
android:id="#+id/emailid"
android:layout_width="156dp"
android:layout_height="45dp"
android:layout_marginTop="5dp"
android:background="#drawable/button"
android:hint="User Name"
android:inputType="text"
android:paddingLeft="10dp"
android:textAppearance="#android:style/TextAppearance.Medium" />
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="15dp"
android:text="Password"
android:textAppearance="#android:style/TextAppearance.Medium" />
<EditText
android:id="#+id/password"
android:layout_width="156dp"
android:layout_height="45dp"
android:layout_marginTop="5dp"
android:background="#drawable/button"
android:hint="Password"
android:inputType="textPassword"
android:paddingLeft="10dp"
android:textAppearance="#android:style/TextAppearance.Medium" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:orientation="horizontal"
<Button
android:id="#+id/login"
android:layout_width="71dp"
android:layout_height="wrap_content"
android:layout_marginBottom="10dp"
android:layout_marginTop="15dp"
android:layout_weight="1"
android:background="#drawable/login"
android:text="Login"
android:textAppearance="#android:style/TextAppearance.Medium"
android:textColor="#000000"
android:typeface="serif" />
<Button android:id="#+id/scan"
and
android:layout_width="71dp"
android:layout_height="wrap_content"
android:layout_marginBottom="10dp"
android:layout_marginTop="15dp"
android:layout_weight="1"
android:background="#drawable/login"
android:text="scan"/>
</LinearLayout>
</LinearLayout>
</LinearLayout>
</LinearLayout>

You can either wrap the buttons within a horizontal LinearLayout like this:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal" >
<Button
android:id="#+id/login"
android:layout_width="71dp"
android:layout_height="wrap_content"
android:layout_marginBottom="10dp"
android:layout_marginTop="15dp"
android:layout_weight="1"
android:background="#drawable/login"
android:text="Login"
android:textAppearance="#android:style/TextAppearance.Medium"
android:textColor="#000000"
android:typeface="serif" />
<Button android:id="#+id/scan"
android:layout_width="71dp"
android:layout_height="wrap_content"
android:layout_marginBottom="10dp"
android:layout_marginTop="15dp"
android:layout_weight="1"
android:background="#drawable/login"
android:text="scan"/>
</LinearLayout>
or use a RelativeLayout.

RealtiveLayout is the best choice:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<Button
android:id="#+id/button01"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/entry"
android:layout_alignParentLeft="true"
android:layout_toLeftOf="#+id/space"
/>
<TextView
android:id="#id/space"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"/>
<Button
android:id="#+id/button02"
android:layout_toRightOf="#id/button01"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="#id/entry"
android:layout_alignParentRight="true"
/>
</RelativeLayout>
Seems like you want two equal buttons, not wrapped content. I created a centered spacer using TextView, and relatively aligned to that. Left button to parent left and spacer, Right button to Left Button and parent right.

This should works:
Change these,
<Button
android:id="#+id/login"
android:layout_width="71dp"
android:layout_height="wrap_content"
android:layout_marginBottom="10dp"
android:layout_marginTop="15dp"
android:layout_weight="1"
android:background="#drawable/login"
android:text="Login"
android:textAppearance="#android:style/TextAppearance.Medium"
android:textColor="#000000"
android:typeface="serif" />
<Button android:id="#+id/scan"
and
android:layout_width="71dp"
android:layout_height="wrap_content"
android:layout_marginBottom="10dp"
android:layout_marginTop="15dp"
android:layout_weight="1"
android:background="#drawable/login"
android:text="scan"/>
with this,
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center"
android:orientation="horizontal" >
<Button
android:id="#+id/login"
android:layout_width="71dp"
android:layout_height="wrap_content"
android:layout_marginBottom="10dp"
android:layout_marginTop="15dp"
android:layout_weight="1"
android:background="#drawable/login"
android:text="Login"
android:textAppearance="#android:style/TextAppearance.Medium"
android:textColor="#000000"
android:typeface="serif" />
<Button
android:id="#+id/scan"
android:layout_width="71dp"
android:layout_height="wrap_content"
android:layout_marginBottom="10dp"
android:layout_marginTop="15dp"
android:layout_weight="1"
android:background="#drawable/login"
android:text="scan" />
</LinearLayout>
