When the icon gravity is textTop, we are using the smaller one of the calculated height from text paint and the text layout height to decide the icon position. This is wrong when there are multiple lines of text since the text paint is always single line and always shorter than the actual height. Fixes this by returning the actual layout height whenever there are multiple lines of text to fix the issue.

/**
|
|
* A convenience class for creating a new Material button.
|
|
*
|
|
* <p>This class supplies updated Material styles for the button in the constructor. The widget will
|
|
* display the correct default Material styles without the use of the style flag.
|
|
*
|
|
* <p>All attributes from {@code com.google.android.material.R.styleable#MaterialButton} are
|
|
* supported. Do not use the {@code android:background} attribute. MaterialButton manages its own
|
|
* background drawable, and setting a new background means {@link MaterialButton} can no longer
|
|
* guarantee that the new attributes it introduces will function properly. If the default background
|
|
* is changed, {@link MaterialButton} cannot guarantee well-defined behavior.
|
|
*
|
|
* <p>For filled buttons, this class uses your theme's {@code ?attr/colorPrimary} for the background
|
|
* tint color and {@code ?attr/colorOnPrimary} for the text color. For unfilled buttons, this class
|
|
* uses {@code ?attr/colorPrimary} for the text color and transparent for the background tint.
|
|
*
|
|
* <p>Add icons to the start, center, or end of this button using the {@code app:icon}, {@code
|
|
* app:iconPadding}, {@code app:iconTint}, {@code app:iconTintMode} and {@code app:iconGravity}
|
|
* attributes.
|
|
*
|
|
* <p>If a start-aligned icon is added to this button, please use a style like one of the ".Icon"
|
|
* styles specified in the default MaterialButton styles. The ".Icon" styles adjust padding slightly
|
|
* to achieve a better visual balance. This style should only be used with a start-aligned icon
|
|
* button. If your icon is end-aligned, you cannot use a ".Icon" style and must instead manually
|
|
* adjust your padding such that the visual adjustment is mirrored.
|
|
*
|
|
* <p>Specify background tint using the {@code app:backgroundTint} and {@code
|
|
* app:backgroundTintMode} attributes, which accepts either a color or a color state list.
|
|
*
|
|
* <p>Ripple color / press state color can be specified using the {@code app:rippleColor} attribute.
|
|
* Ripple opacity will be determined by the Android framework when available. Otherwise, this color
|
|
* will be overlaid on the button at a 50% opacity when button is pressed.
|
|
*
|
|
* <p>Set the stroke color using the {@code app:strokeColor} attribute, which accepts either a color
|
|
* or a color state list. Stroke width can be set using the {@code app:strokeWidth} attribute.
|
|
*
|
|
* <p>Specify the radius of all four corners of the button using the {@code app:cornerRadius}
|
|
* attribute.
