Question

I have a Linear Layout with 2 buttons of equal weights. So they occupy the whole screen(width wise).

In another Linear Layout below the 1st, i only have 1 button, whose width i want to be same as any 1 of the previous 2 buttons.

Is there a simple way to do, other than using gridview or tableview etc..,

I tried this:

Button one = (Button) findViewById(R.id.one);
Button two = (Button) findViewById(R.id.two);
Button three = (Button) findViewById(R.id.three);

three.setLayoutParams(new LinearLayout.LayoutParams(
        one.getLayoutParams()));

Layout:

<LinearLayout
            xmlns:android="http://schemas.android.com/apk/res/android"
            xmlns:tools="http://schemas.android.com/tools"
            android:id="@+id/first"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:orientation="horizontal" >

        <Button
            android:id="@+id/one"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1" />

        <Button
            android:id="@+id/two"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1" />
    </LinearLayout>

    <LinearLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        android:id="@+id/second"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_below="@id/first"
        android:orientation="horizontal" >

        <Button
            android:id="@+id/three"
            android:layout_width="150dp"
            android:layout_height="wrap_content" />
    </LinearLayout>

But the 3rd Button is invisible now.

Thank You

try this for second row

<LinearLayout
    android:id="@+id/second"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_below="@id/first1"
    android:weightSum="2"
    android:orientation="horizontal" >

    <Button
        android:layout_weight="1"
        android:id="@+id/three"
        android:layout_width="0dp"
        android:layout_height="wrap_content" />
</LinearLayout>
