Example 71 with TypedValue

use of android.util.TypedValue in project platform_frameworks_base by android.

the class TypedArray method getDimensionPixelSize.

     * rounding the base value, and ensuring that a non-zero base value
     * is at least one pixel in size.
     * <p>
     * This method will throw an exception if the attribute is defined but is
     * not a dimension.
