Checking screenSize is not working

This is my code for checking screen sizes and changing the FrameLayout size. 

    FrameLayout topLayout = (FrameLayout) findViewById(R.id.topLayout);

    DisplayMetrics dm = new DisplayMetrics();
    getWindowManager().getDefaultDisplay().getMetrics(dm);
    double x = Math.pow(dm.widthPixels/dm.xdpi,2);
    double y = Math.pow(dm.heightPixels / dm.ydpi, 2);
    double screenInches = Math.sqrt(x + y);

    if (screenInches < 5) topLayout.setLayoutParams(new LinearLayout
    .LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,170));
    if (screenInches >= 5 && screenInches < 7) topLayout
    .setLayoutParams(new LinearLayout 
    .LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, 200));
    else topLayout.setLayoutParams(new LinearLayout
    .LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, 230));

I don't know why its not working.

You can use DisplayMetrics .

A structure describing general information about a display, such as its size, density, and font scaling.

   DisplayMetrics metrics = getResources().getDisplayMetrics();

   int DeviceTotalWidth = metrics.widthPixels;
   int DeviceTotalHeight = metrics.heightPixels;
   FrameLayout topLayout = (FrameLayout) findViewById(R.id.topLayout);

   topLayout.getLayoutParams().height= (DeviceTotalHeight/4); // Use Your Logic

Now you can use your screenInches logic simply .

in order to change layout parameter you have to do this:

topLayout.getLayoutParams().width = 100;
topLayout.getLayoutParams().height = 100;

DisplayMetrics displaymetrics = new DisplayMetrics();
((Activity)mContext)getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
int height = displaymetrics.heightPixels;
int width = displaymetrics.widthPixels;
