Gradient effect

SuperTextView supports gradient effects by configuring simple properties.

# You must be set to true to enable gradients. This means you have the flexibility to control this feature.
app:stv_shaderEnable="true"

# Set the starting color
app:stv_shaderStartColor="@color/main_blue"

# Set the ending color.
app:stv_shaderEndColor="@color/pink"

# Set the gradient mode. As can be seen from the above figure, a total of 4 modes are supported:
# topTopBottom, bottomToTop, leftToRight, rightToLeft
app:stv_shaderMode="rightToLeft"

These properties are also supported in Java.

// Turn on the gradient function
stv.setShaderEnable(true);
// Set the starting color
stv.setShaderStartColor(Color.BLUE);
// Set the ending color.
stv.setShaderEndColor(Color.RED);
// Set the gradient mode.
stv.setShaderMode(SuperTextView.ShaderMode.LEFT_TO_RIGHT);

There are 4 types of gradient modes:

public static enum ShaderMode {
/**
* From top to bottom
*/
TOP_TO_BOTTOM(0),
/**
* From bottom to top
*/
BOTTOM_TO_TOP(1),
/**
* From left to right
*/
LEFT_TO_RIGHT(2),
/**
* From right to left
*/
RIGHT_TO_LEFT(3);
}
