How To Arrange Width And Height Of Relative Layout To Be Half Of The Screen

I am developing an android application and I want to set my relative layout's width and height as half of my screen width and height. Thanks

Solution 1:

Use Parent as the LinearLayout and use weightSum and weight attributes

Sample

<LinearLayoutxmlns:android="http://schemas.android.com/apk/res/android"xmlns:tools="http://schemas.android.com/tools"android:layout_width="match_parent"android:layout_height="match_parent"android:orientation="vertical"android:weightSum="100" ><RelativeLayoutandroid:id="@+id/button1"android:layout_width="match_parent"android:layout_height="0dp"android:layout_weight="50" ><!-- Your RelativeLayout Items --></RelativeLayout></LinearLayout>

Solution 2:

To Divide a Relative layout into two equal relative layouts

<RelativeLayoutandroid:layout_width="match_parent"android:layout_height="match_parent"android:baselineAligned="false"><RelativeLayoutandroid:layout_width="0dp"android:layout_height="wrap_content"android:layout_weight="1"></RelativeLayout><RelativeLayoutandroid:layout_width="0dp"android:layout_height="wrap_content"android:layout_weight="1"></RelativeLayout></RelativeLayout>

and to Divide a linear layout into two equal relative layouts

<LinearLayoutandroid:layout_width="match_parent"android:layout_height="match_parent"android:orientation="horizontal"android:baselineAligned="false"><RelativeLayoutandroid:layout_width="0dp"android:layout_height="wrap_content"android:layout_weight="1"></RelativeLayout><RelativeLayoutandroid:layout_width="0dp"android:layout_height="wrap_content"android:layout_weight="1"></RelativeLayout></LinearLayout>

Solution 3:

*@SuppressLint("NewApi")publicstaticintgetDeviceWidth(Activity activity) {
    intdeviceWidth=0;

    Pointsize=newPoint();
    WindowManagerwindowManager= activity.getWindowManager();

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
        windowManager.getDefaultDisplay().getSize(size);
        deviceWidth = size.x;
    } else {
        Displaydisplay= windowManager.getDefaultDisplay();
        deviceWidth = display.getWidth();
    }
    return deviceWidth;
}

@SuppressLint("NewApi")publicstaticintgetDeviceHeight(Activity activity) {
    intdeviceHeight=0;

    Pointsize=newPoint();
    WindowManagerwindowManager= activity.getWindowManager();

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
        windowManager.getDefaultDisplay().getSize(size);
        deviceHeight = size.y;
    } else {
        Displaydisplay= windowManager.getDefaultDisplay();
        deviceHeight = display.getHeight();
    }
    return deviceHeight;
}*

above two function is get device height and width.

Use on this function, you can get half of the size of screen. I hope its useful to you.

Solution 4:

You need to put the RelativeLayout inside a LinearLayout and use android:weightsum=2 and android:layout_weight=1 to get the desired proportion

<?xml version="1.0" encoding="utf-8"?><LinearLayoutxmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="match_parent"android:layout_height="match_parent"android:orientation="horizontal"android:weightSum="2" ><RelativeLayout....android:layout_weight=1....></RelativeLAyout></LinearLayout>
