Question

I want to create TextInputLayout with Widget.MaterialComponents.TextInputLayout.OutlinedBox style. I tried many ways but couldn\'t get the required result. Here is my code.

Answer 1

UPDATE

Thanks to @Mike M.

You need to use TextInputLayout.setBoxBackgroundMode() method to use OutlineBox style

setBoxBackgroundMode (int boxBackgroundMode)

• Set the mode for the box's background (filled, outline, or none).

Then you need to use TextInputLayout.BOX_BACKGROUND_OUTLINE) Constants

NOTE: To get the corner in your OutlineBox of TextInputLayout you need to use setBoxCornerRadii() method

SAMPLE CODE

public class MainActivity extends AppCompatActivity {

    LinearLayout parentView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        parentView = findViewById(R.id.parentView);

        TextInputLayout emailTextInputLayout = new TextInputLayout(this, null, R.style.Widget_MaterialComponents_TextInputLayout_OutlinedBox);

        emailTextInputLayout.setHint("Please Enter Email Address");
        emailTextInputLayout.setBoxBackgroundMode(TextInputLayout.BOX_BACKGROUND_OUTLINE);
        emailTextInputLayout.setBoxCornerRadii(5, 5, 5, 5);
        TextInputEditText edtEmail = new TextInputEditText(emailTextInputLayout.getContext());
        emailTextInputLayout.addView(edtEmail);

        parentView.addView(emailTextInputLayout);


        TextInputLayout passTextInputLayout = new TextInputLayout(this, null, R.style.Widget_MaterialComponents_TextInputLayout_OutlinedBox);

        passTextInputLayout.setHint("Please Enter Password");
        passTextInputLayout.setBoxBackgroundMode(TextInputLayout.BOX_BACKGROUND_OUTLINE);
        passTextInputLayout.setBoxCornerRadii(5, 5, 5, 5);
        TextInputEditText edtPass = new TextInputEditText(passTextInputLayout.getContext());
        passTextInputLayout.addView(edtPass);

        parentView.addView(passTextInputLayout);


    }

}

Based on this answer: https://stackoverflow.com/questions/3246447/how-to-set-the-style-attribute-programmatically-in-android

• Dynamic style change is not currently supported. You must set the style before the view is created (in XML).

That's the reason that TextInputLayout does not programmatically accept setting the outline boxed style.

Here is the simple solution:

You can use LayoutInflater

• Instantiates a layout XML file into its corresponding View objects.

DEMO

Create a new layout

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.TextInputLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/userIDTextInputLayout"
    style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_margin="10dp">

    <android.support.design.widget.TextInputEditText
        android:id="@+id/userIDTextInputEditText"
        android:layout_width="match_parent"
        android:hint="Enter User Name"
        android:layout_height="wrap_content" />
</android.support.design.widget.TextInputLayout>

AndroidX (+Material Components for Android):

<?xml version="1.0" encoding="utf-8"?>
<com.google.android.material.textfield.TextInputLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/userIDTextInputLayout"
    style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_margin="10dp">

    <com.google.android.material.textfield.TextInputEditText 
        android:id="@+id/userIDTextInputEditText"
        android:layout_width="match_parent"
        android:hint="Enter User Name"
        android:layout_height="wrap_content" />
</com.google.android.material.textfield.TextInputLayout>

Now using LayoutInflater add that TextInputLayout in your required layout

public class MainActivity extends AppCompatActivity {

    LinearLayout rootView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        rootView = findViewById(R.id.rootView);

        View view = LayoutInflater.from(this).inflate(R.layout.temp_layout, null);
        TextInputLayout userNameIDTextInputLayout=view.findViewById(R.id.userIDTextInputLayout);
        TextInputEditText userNameInputEditText = view.findViewById(R.id.userIDTextInputEditText);
        userNameIDTextInputLayout.setHint("Please Enter User Name");
        rootView.addView(view);
    }
}

You can use the method applyStyle defined on the Theme class. In Kotlin, you can access it with the theme property on a Context (or subclass) instance.

The applyStyle function allows you to add a style to the current theme, that defines theme attributes referencing styles. After calling this method, you can pass the attribute as the third parameter of a View, like TextInputLayout, which will apply the desired styles while respecting the theme.

I used this technique in Splitties (a library which I authored), and there's some documentation plus examples that should help you: https://github.com/LouisCAD/Splitties/blob/v3.0.0-alpha02/views-dsl/README.md#using-styles-defined-in-xml

I did not yet add first class support for themes from Material Components in Splitties Views DSL, but you can do it yourself, and you can even open an issue to discuss it, or contribute so it gets integrated sooner.
