Set two buttons to same width regardless of screen size?

Question

Ok, i have two buttons in linear layout:

Answer 1

Display display=getWindowManager().getDefaultDisplay();
    int width=display.getWidth();
    btn1.setWidth(width/2);
    btn2.seTwidth(width/2);

Set anything in xml file then first find width of device then set width half to both button Now On every device they will look exactly same

Answer 2

Set android:layout_weight="1" in the containing layout The linear layout should have android:orientation set as horizontal. And then the inside buttons should have the following:

android:layout_width="0dp"

android:layout_weight="0.5"

Answer 3

You can set them in linear layout nested in relative layout like this

<LinearLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:layout_centerHorizontal="true"
    android:gravity="center"
    android:orientation="vertical">



        <Button
            android:id="@+id/bestBtn"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:textStyle="bold"
            android:layout_marginBottom="5dp"
            android:textAllCaps="false"
            android:textSize="16sp"
            android:textColor="@color/grey_light2"
            android:background="@drawable/sharefb_btn"
            android:text="@string/sharefb" />
        <Button
            android:id="@+id/playBtn"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:textColor="@color/grey_light2"
            android:textAllCaps="false"
            android:textSize="16sp"
            android:layout_marginBottom="50dp"
            android:textStyle="bold"
            android:background="@drawable/puzzle_opening_btn_ncvtelen_3"
            android:text="@string/playagain" />

</LinearLayout>
