Set two buttons to same width regardless of screen size?

Question

Ok, i have two buttons in linear layout:

Answer 1

android:layout_weight="0.5"
android:layout_width="0dp

it's working

Answer 2

<LinearLayout
    android:id="@+id/layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal" >

    <Button
        android:id="@+id/button1"
        android:layout_width="match_parent"
        android:layout_height="40dp"
        android:layout_weight="1"
        android:text="One" />

    <Button
        android:id="@+id/button2"
        android:layout_width="match_parent"
        android:layout_height="40dp"
        android:layout_weight="1"
        android:text="Two" />
</LinearLayout>

These is the example for equal size buttons for side by side can be done from above code

android:layout_weight 

is used to assign space for buttons or whatever of equal amount for every child of LinearLayout.

Note: It works only on linear layout.

Answer 3

This is working:

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal">
    <Button
        android:layout_width="0dp"
        android:layout_weight="0.5"
        android:layout_height="wrap_content"
        android:text="my btn 1"/>
    <Button
        android:layout_width="0dp"
        android:layout_weight="0.5"
        android:layout_height="wrap_content"
        android:text="my btn 2"/>
    </LinearLayout>

Answer 4

Use android:layout_weight="1" on both Buttons. Set android:layout_width="0dp" on both. Since both buttons now have equal weighting, they will now each have half the parent's width.

Answer 5

If what you're looking to do is to make all the buttons the width of the widest button, setting weights isn't going to do that. Rather, you can put all the buttons in a TableLayout:

   <TableLayout 
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" >

        <TableRow
            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:text="@string/short_text" />
        </TableRow>

        <TableRow
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" >

            <Button
                android:id="@+id/button2"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="@string/enter_manually" />
        </TableRow>
    </TableLayout>

This layout will show 2 buttons, one on top of the other, the same width.

Answer 6

set to each button:

android:layout_weight="0.5"
android:layout_width="0dp"
