I made an application where I create part of the interface in xml and part via java code, the part in xml works in any application adapting the screen size correctly. The part via code on a 7.8-inch device looks good, however on a 4-inch screen it's all unconfigured (source of the giant views). I've done a lot of research on the internet and nothing works. Anyone know what I can do? Thank you in advance.

I tried to use this code but it did not work:

tv2.setTextSize(20 * getResources().getDisplayMetrics().scaledDensity);

java android

If the problem is only the size of the fonts, you can use the following to solve your problem.

You must first determine which device is running your application.

    DisplayMetrics metrics = new DisplayMetrics();
    getWindowManager().getDefaultDisplay().getMetrics(metrics);

    int widthPixels = metrics.widthPixels;
    int heightPixels = metrics.heightPixels;

    float scaleFactor = metrics.density;

    float widthDp = widthPixels / scaleFactor;
    float heightDp = heightPixels / scaleFactor;

    float smallestWidth = Math.min(widthDp, heightDp);

After discovering the value of smallestWidth you can determine whether you are running the application on a 7, 10-inch tablet or a smartphone and adjust the text size accordingly.

// tamanho para smartphone
int size = 10

if (smallestWidth > 720) {
    //tablet de 10"
    size = 20

} else if (smallestWidth > 600) {
    //tablet de 7"
    size = 15
}

After determining the size you can configure your view.

tv2.setTextSize(size)

I hope I have helped.
