Define layout size in JAVA depending of the screen size (android)

I want to display a dialog when I click on a button. I've done a custom dialog like that :

final Dialog dialog = new Dialog(context);
dialog.setContentView(R.layout.dialog);
Button dialogButton = (Button) dialog.findViewById(R.id.dialogButtonOK);

dialogButton.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        dialog.dismiss();
    }
});

dialog.setCanceledOnTouchOutside(false);
Window window = dialog.getWindow();
window.setLayout(300, 450);
dialog.show();

As you can see, I define the size of the layout with window.setLayout in java, because it doesn't work on xml for the dialog (and I can't put the dialog theme on the activity). I would like to set a layout size in java depending of the screen size as for xml with layout-large and xlarge (as I explained, I can't use the xml to define the layout depending on the screen size).

Thanks,

You can configure it on the dimens.xml file on the values folder. You can specify a values folder for different screen sizes like this:

values-w820dp

and the dimens.xml file example:

<resources>
    <dimen name="dialog_height">64dp</dimen>
    <dimen name="dialog_width">64dp</dimen>
</resources>

Here you have more info about it.

Then on your code you can access it like this 

int dialogHeight = (int) getResources().getDimension(R.dimen.dialog_height)
int dialogWidth = (int) getResources().getDimension(R.dimen.dialog_width)

getResources().getDimension() will resolve the right dimension from the right folder based on the device automatically.

Here you have some common configurations:

  • 320dp: a typical phone screen (240x320 ldpi, 320x480 mdpi, 480x800 hdpi, etc).
  • 480dp: a tweener tablet like the Streak (480x800 mdpi).
  • 600dp: a 7” tablet (600x1024 mdpi).
  • 720dp: a 10” tablet (720x1280 mdpi, 800x1280 mdpi, etc).

Hope it helps.

  1. get screen size (width and height)
  2. set it to the dialog .

Here is the Code

            final Dialog dialog = new Dialog(context);
            dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
            dialog.setCancelable(false);
            dialog.setContentView(R.layout.dialog_customer);
            try {
                LinearLayout lytdialog = (LinearLayout) dialog.findViewById(R.id.dialog);
                Display display = getWindowManager().getDefaultDisplay();
                Point size = new Point();
                display.getSize(size);
                int height = size.y;
                int width = size.x;
                android.view.ViewGroup.LayoutParams layoutParams = lytdialog.getLayoutParams();
                layoutParams.width = width;
                layoutParams.height = WindowManager.LayoutParams.WRAP_CONTENT;
                lytdialog.setLayoutParams(layoutParams);
            } catch (Exception e) {
                e.printStackTrace();
            }

            dialog.show();
        }

Happy Coding

Display display = getWindowManager().getDefaultDisplay();
Point size = new Point();
display.getSize(size);
int width = size.x;
int height = size.y;
