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.

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"

  • Hello Antonis. Thank you for your reply. I have tried the following: 1. I have renamed values-sw600dp-mdpi to values-sw600dp. 2. I have removed the values-sw360dp-xxhdpi resource directory. But it has not made a difference. I have updated my original question to include some code. – Jehanzeib Sep 03 '17 at 17:34
  • @Jehanzeib You can use this line `textView.setTextSize(12,getResources().getDimension(R.dimen.randrom_text_font_size));` and adjust the 12 in it according to your need. – Lalit Fauzdar Sep 03 '17 at 18:29
  • textView.setTextSize(0,getResources().getDimension(R.dimen.randrom_text_font_size)); always use 0 here if you have decrare your font size in sp in your dimens file – Antonis Lat Sep 03 '17 at 18:39
  • if the above solution does not work for you, create values-large/dimens.xml and put tablet's font size there with the same format and the java code i proposed above. – Antonis Lat Sep 03 '17 at 18:42
  • @AntonisLat Thank you so much! That now works. Just one question; why do I not need to define a separate values directory for the mobile? How does it know to pick up the dimens from the default values directory? – Jehanzeib Sep 03 '17 at 19:42
