Android Checkbox Tint Color - Java

Android Checkbox is a UI element that allows users to select one or more options from a set of choices. By default, the checkbox uses the device's default accent color. However, this default color may not always match your app's theme. If you want to change the color of the checkbox, you can use the tinting feature.

The tinting feature allows you to change the color of the checkbox without changing its shape or size. You can apply different tint colors to the checkbox in various states, such as checked and unchecked states. In this article, we will discuss how to change the tint color of the checkbox in Java.

Setting Tint Color

To set the tint color of the checkbox, you need to use the setButtonTintList method of the CheckBox class. This method takes a ColorStateList object as its parameter. Here's how you can set the tint color of the checkbox in Java:

// get the checkbox
CheckBox cb = findViewById(R.id.checkbox);

// create a color state list
ColorStateList colorStateList = ColorStateList.valueOf(ContextCompat.getColor(this, R.color.checkbox_tint_color));

// set the tint color of the checkbox
cb.setButtonTintList(colorStateList);

In the above example, we first get the checkbox using its ID. Then, we create a ColorStateList object by getting the color from the resources using the ContextCompat.getColor method. Finally, we set the tint color of the checkbox using the setButtonTintList method.

Setting Tint Color for Different States

You can also set different tint colors for different states of the checkbox, such as checked and unchecked states. To do this, you need to create a ColorStateList object with different colors for each state. Here's an example:

// get the checkbox
CheckBox cb = findViewById(R.id.checkbox);

// create a color state list with different colors for different states
int[][] states = new int[][]{
    new int[]{-android.R.attr.state_checked}, // unchecked state
    new int[]{android.R.attr.state_checked}   // checked state
};

int[] colors = new int[]{
    ContextCompat.getColor(this, R.color.checkbox_unchecked_tint_color),
    ContextCompat.getColor(this, R.color.checkbox_checked_tint_color)
};

ColorStateList colorStateList = new ColorStateList(states, colors);

// set the tint color of the checkbox
cb.setButtonTintList(colorStateList);

In the above example, we create a two-dimensional array of states, one for the unchecked state and one for the checked state. We also create an array of colors corresponding to the states. Then, we create a ColorStateList object with these arrays and set it as the tint color of the checkbox.

Conclusion

In this article, we discussed how to change the tint color of the Android Checkbox in Java. You can use the setButtonTintList method of the CheckBox class to set the tint color of the checkbox. You can also set different tint colors for different states of the checkbox using the ColorStateList object. By using these techniques, you can customize the look and feel of your Checkbox to match your app's theme.
