I always read about this funny weight value in the Android documentations. Now I want to try it for the first time but it isn\'t working at all.
As I understand it
Try setting the layout_width
of both buttons to "0dip" and the weight
of both buttons to 0.5
This is perfect answer of your problem
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<Button
android:text="Register" android:id="@+id/register"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:padding="10dip" weight="1" />
<Button
android:text="Not this time" android:id="@+id/cancel"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:padding="10dip" weight="1" />
</LinearLayout>
LinearLayout supports assigning a weight to individual children. This attribute assigns an "importance" value to a view, and allows it to expand to fill any remaining space in the parent view. Default weight is zero
calculation to assign any Remaining/Extra space between child. (not the total space)
space assign to child = (child individual weight) / (sum of weight of every child in Linear Layout)
Example (1): if there are three text boxes and two of them declare a weight of 1, while the third one is given no weight (0), then Remaining/Extra space assign to
1st text box = 1/(1+1+0)
2nd text box = 1/(1+1+0)
3rd text box = 0/(1+1+0)
Example (2) : let's say we have a text label and two text edit elements in a horizontal row. The label has no layout_weight specified, so it takes up the minimum space required to render. If the layout_weight of each of the two text edit elements is set to 1, the remaining width in the parent layout will be split equally between them (because we claim they are equally important).
calculation :
1st label = 0/(0+1+1)
2nd text box = 1/(0+1+1)
3rd text box = 1/(0+1+1)
If the first one text box has a layout_weight of 1 and the second text box has a layout_weight of 2, then one third of the remaining space will be given to the first, and two thirds to the second (because we claim the second one is more important).
calculation :
1st label = 0/(0+1+2)
2nd text box = 1/(0+1+2)
3rd text box = 2/(0+1+2)
<LinearLayout

android:layout_height="wrap_content"
android:baselineAligned="true"

<Button

You have to write like this its Working for me
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:weightSum="2">
<Button
android:text="Register"
android:id="@+id/register"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="10dip"
android:layout_weight="1" />
<Button
android:text="Not this time"
android:id="@+id/cancel"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="10dip"
android:layout_weight="1" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center"
android:background="#008">
<RelativeLayout
android:id="@+id/paneltamrin"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center"
>
<Button
android:id="@+id/BtnT1"
android:layout_width="wrap_content"
android:layout_height="150dp"
android:drawableTop="@android:drawable/ic_menu_edit"
android:drawablePadding="6dp"
android:padding="15dp"
android:text="AndroidDhina"
android:textColor="#000"
android:textStyle="bold" />
</RelativeLayout>
<RelativeLayout
android:id="@+id/paneltamrin2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center"
>
<Button
android:layout_width="wrap_content"
android:layout_height="150dp"
android:drawableTop="@android:drawable/ic_menu_edit"
android:drawablePadding="6dp"
android:padding="15dp"
