How Can I set style to TextInputLayout by dynamically in android?

Question

I want to create TexInputLayout by dynamically. I can create TextInputLayout using following code block :

TextInputLayout til = new TextInputLayout(this);
EditText et = new EditText(this);
til.addView(et);
et.setHint("Enter");
information.addView(til);

information is name of my linear layout which I use in the project.

But I want to change style of the TextInputLaout which I created by dynamically, I want to use @style/Widget.MaterialComponents.TextInputLayout.OutlinedBox.

I tried the following code block to change style :

TextInputLayout till= new TextInputLayout(new ContextThemeWrapper(this, 
 R.style.Widget_MaterialComponents_TextInputLayout_OutlinedBox));
 EditText et = new EditText(this);
 til.addView(et);
 et.setHint("Enter");
 information.addView(til);

but these code is not working. How can add style to TextInputLayout which I created dynamically ?

Answer 1

The 2nd parameter of the ContextThemeWrapper is a theme overlay, not a style.

You can define in attrs.xml a custom attribute:

<attr name="customTextInputStyle" format="reference" />

then in your app theme:

<style name="AppTheme" parent="Theme.MaterialComponents.*">
    <!-- ..... -->
    <item name="customTextInputStyle">@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox</item>
</style>

and finally:

    TextInputLayout til = new TextInputLayout(this,null,R.attr.customTextInputStyle);
    til.setHint("Label");
    TextInputEditText et = new TextInputEditText(til.getContext());  //important: get the themed context from the TextInputLayout
    til.addView(et);
    buttonsLayout.addView(til);
