custom - set style dynamically android

How to programmatically set style attribute in a view (8)

At runtime, you know what style you want your button to have. So beforehand, in xml in the layout folder, you can have all ready to go buttons with the styles you need. So in the layout folder, you might have a file named: button_style_1.xml. The contents of that file might look like:

<?xml version="1.0" encoding="utf-8"?>
    style="@style/FirstStyle" />

If you are working with fragments, then in onCreateView you inflate that button, like:

Button firstStyleBtn = (Button) inflater.inflate(R.layout.button_style_1, container, false);

where container is the ViewGroup container associated with the onCreateView method you override when creating your fragment.

Need two more such buttons? You create them like this:

Button secondFirstStyleBtn = (Button) inflater.inflate(R.layout.button_style_1, container, false);
Button thirdFirstStyleBtn = (Button) inflater.inflate(R.layout.button_style_1, container, false);

You can customize those buttons:

secondFirstStyleBtn.setText("My Second");
thirdFirstStyleBtn.setText("My Third");

Then you add your customized, stylized buttons to the layout container you also inflated in the onCreateView method:

_stylizedButtonsContainer = (LinearLayout) rootView.findViewById(;


And that's how you can dynamically work with stylized buttons.

I'm getting a view from the XML with the code below:

Button view = (Button) LayoutInflater.from(this).inflate(R.layout.section_button, null);

I would like to set a "style" for the button how can I do that in java since a want to use several style for each button I will use.

Depending on what style attributes you'd like to change you may be able to use the Paris library:

Button view = (Button) LayoutInflater.from(this).inflate(R.layout.section_button, null);;

Many attributes like background, padding, textSize, textColor, etc. are supported.

Disclaimer: I authored the library.

For anyone looking for a Material answer see this SO post: Coloring Buttons in Android with Material Design and AppCompat

I used a combination of this answer to set the default text color of the button to white for my button: https://.com/a/32238489/3075340

Then this answer https://.com/a/34355919/3075340 to programmatically set the background color. The code for that is:


your_colored_button can be just a regular Button or a AppCompat button if you wish - I tested the above code with both types of buttons and it works.

EDIT: I found that pre-lollipop devices do not work with the above code. See this post on how to add support for pre-lollipop devices: https://.com/a/30277424/3075340

Basically do this:

Button b = (Button) findViewById(;
ColorStateList c = ContextCompat.getColorStateList(mContext, R.color.your_custom_color;
Drawable d = b.getBackground();
if (b instanceof AppCompatButton) {
    // appcompat button replaces tint of its drawable background
    // Lollipop button replaces tint of its drawable background
    // however it is not equal to d.setTintList(c)
} else {
    // this should only happen if 
    // * manually creating a Button instead of AppCompatButton
    // * LayoutInflater did not translate a Button to AppCompatButton
    d = DrawableCompat.wrap(d);
    DrawableCompat.setTintList(d, c);

Generally you can't change styles programmatically; you can set the look of a screen, or part of a layout, or individual button in your XML layout using themes or styles. Themes can, however, be applied programmatically.

There is also such a thing as a StateListDrawable which lets you define different drawables for each state the your Button can be in, whether focused, selected, pressed, disabled and so on.

For example, to get your button to change colour when it's pressed, you could define an XML file called res/drawable/my_button.xml directory like this:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="">
    android:drawable="@drawable/btn_pressed" />
    android:drawable="@drawable/btn_normal" />

You can then apply this selector to a Button by setting the property android:background="@drawable/my_button".

I made a helper interface for this using the holder pattern.

public interface StyleHolder<V extends View> {
    void applyStyle(V view);

Now for every style you want to use pragmatically just implement the interface, for example:

public class ButtonStyleHolder implements StyleHolder<Button> {

    private final Drawable background;
    private final ColorStateList textColor;
    private final int textSize;

    public ButtonStyleHolder(Context context) {
        TypedArray ta = context.obtainStyledAttributes(, R.styleable.ButtonStyleHolder);

        Resources resources = context.getResources();

        background = ta.getDrawable(ta.getIndex(R.styleable.ButtonStyleHolder_android_background));

        textColor = ta.getColorStateList(ta.getIndex(R.styleable.ButtonStyleHolder_android_textColor));

        textSize = ta.getDimensionPixelSize(

        // Don't forget to recycle!

    public void applyStyle(Button btn) {
        btn.setTextSize(TypedValue.COMPLEX_UNIT_PX, textSize);

Declare a stylable in your attrs.xml, the styleable for this example is:

<declare-styleable name="ButtonStyleHolder">
    <attr name="android:background" />
    <attr name="android:textSize" />
    <attr name="android:textColor" />

Here is the style declared in styles.xml:

<style name="button">
    <item name="android:background">@drawable/button</item>
    <item name="android:textColor">@color/light_text_color</item>
    <item name="android:textSize">@dimen/standard_text_size</item>

And finally the implementation of the style holder:

Button btn = new Button(context);    
StyleHolder<Button> styleHolder = new ButtonStyleHolder(context);

I found this very helpful as it can be easily reused and keeps the code clean and verbose, i would recommend using this only as a local variable so we can allow the garbage collector to do its job once we're done with setting all the styles.

If you are using the Support library, you could simply use


for TextViews and Buttons. There are similar classes for the rest of Views :-)

Yes, you can use for example in a button

Button b = new Button(this);

You can do style attributes like so:

Button myButton = new Button(this, null,android.R.attr.buttonBarButtonStyle);
