Test the size of a text on a button with getTextSize()

I need to check if the text size on a button have the size 37sp. I found a method to get the size with: .getTextSize(), but the size with I receive is: 126.0, and not 48sp. The code off button:

<Button
    android:id="@+id/buttoneql"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="="
    android:textColor="@android:color/black"
    android:textSize="48sp" />

The test:

buttoneql = (Button) currentActivity.findViewById(R.id.buttoneql);
assertEquals( 48.0f, buttoneql.getTextSize() );

How I should do to recive the ral value of the text size?

Solution

  • I solved the problem by multiplying the value I need (128.0) by 2.625 and rounding it up correctly to make it an integer.

    int size = (int) Math.round (48.0 * 2.625);

    And after, comparing to the receive value:

    assertEquals(size, (int) buttoneql.getTextSize());
