Android dimens file for multiple screens

Question

I am new to working with multiple screens and need help with the following:

I have 2 devices:

1. Samsung S4

   • display class: normal
   • smallest width: 360dp
   • resolution: 1080 * 1920
   • Density class: XXHDPI
   • Density: 442dpi

2. Samsung Tablet:

   • display class: large
   • smallest width: 600dp
   • resolution: 600 * 1024
   • Density class: MDPI
   • Density: 168dpi

My problem is that the values for both devices are getting pulled from the same dimens file.

• If I have small text, it looks OK on phone, but too small on tablet
• If I have large text, it looks OK on tablet, but too small on phone

Can you please tell me what the name of the values directory should be for each?

I have tried:

values-sw360dp-xxhdpi values-sw600dp-mdpi

However, this has not made a difference.

I have a method:

public void setTextSize(Context context, TextView view, int textSizeInSp)
{
  float spToPixel= TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_SP, textSizeInSp, context.getResources().getDisplayMetrics());

  view.setTextSize(convertSpToPixels(spToPixel, getApplicationContext()));
}

I have 2 dimens file entries:

values-sw360dp-xxhdpi\dimens

<dimen name="font_english_large">20sp</dimen>

values-sw600dp-mdpi\dimens

<dimen name="font_english_large">32sp</dimen>

I programmatically attempt to change the text size by calling:

setTextSize(this, textView, (int)getResources().getDimension(R.dimen.font_english_large);

Thank you.

Answer 1

you will need only values and values-large, then add your font sizes in the corresponding files using sp metrics. For example in values/dimens.xml add

<dimen name="randrom_text_font_size">18sp</dimen>

and in values-sw600dp/dimens.xml add something like

<dimen name="randrom_text_font_size">28sp</dimen>

Then in your java code:

textView.setTextSize(0,getResources().getDimension(R.dimen.randrom_text_font_size));

Or in XML

 android:textSize="@dimen/randrom_text_font_size"
