Problem with app layout for phones with different screen densities

I have problem with layout of my app for below phones . in first one layout looking good but in the second phone the layout not exactly like first one . though i put the xml files in (Layout-w480dp) folder and i do not use constraint layout

huawei G8 : Photo Resolution : 1920 x 1080 px Screen Density : 403 ppi Screen Density (DPI) : 480 ppi (xxhdpi) (640dp) x (360dp)

Solution

  • add this attribute to your textView in xml app:autoSizeTextType="uniform" this will resize the text size to fit the textview area 

      <TextView
    android:layout_width="50sp"
    android:layout_height="50sp"
    android:text="Hello World!"
    app:autoSizeTextType="uniform"    
    tools:ignore="MissingPrefix" />

    for further customizing you can set 

        app:autoSizeMaxTextSize="100sp"
    app:autoSizeMinTextSize="20sp"
    app:autoSizePresetSizes="@array/autosize_text_sizes"

    where autosize_text_sizes is an array in arrays.xml values res file create it by right click on values -> new -> values resource file -> name it arrays.xml, which choose dynamically the text size based on text area availability 

    <?xml version="1.0" encoding="utf-8"?>
<resources>

<array name="autosize_text_sizes">
    <item>10sp</item>
    <item>50sp</item>
    <item>150sp</item>
</array>
