I am using this to display a Spinner type of view for TextInputLayout but I am not getting how can I set any default value to it.

<com.google.android.material.textfield.TextInputLayout
    style="@style/Widget.MaterialComponents.TextInputLayout.FilledBox.ExposedDropdownMenu"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:hintTextColor="@color/primary_color_3">

    <AutoCompleteTextView
        android:id="@+id/accType_dropdown"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:backgroundTint="@android:color/transparent"
        android:inputType="none"
        android:text="@={viewModel.mytext}"
        android:lineSpacingExtra="5sp"
        android:textColor="@color/name_primary_color"
        android:textSize="14sp" />

</com.google.android.material.textfield.TextInputLayout>

The placeholder only works when it is in focus mode so please suggest a workaround.

Edit:

I am using two way data binding in this textview and it seems due to this no solution is working in my case. Even i try to set default value for binded object then it automatically pop ups the spinner on application launch which i don't need so please suggest me something.

The AutoCompleteTextView can work with an Adapter.

Just for example:

<com.google.android.material.textfield.TextInputLayout
        android:id="@+id/til"
        ..>
               
    <com.google.android.material.textfield.MaterialAutoCompleteTextView
       .../>


</com.google.android.material.textfield.TextInputLayout>

Create the adapter:

    ArrayList<String> items = new ArrayList<>();
    items.add("Material");
    items.add("Design");
    items.add("Components");

    ArrayAdapter<String> adapter = new ArrayAdapter<>(this,R.layout.item, items);
    TextInputLayout textInputLayout = findViewById(R.id.til);

Set the default value and the adapter:

    ((MaterialAutoCompleteTextView) textInputLayout.getEditText()).setAdapter(adapter);
    ((MaterialAutoCompleteTextView) textInputLayout.getEditText()).setText(adapter.getItem(1),false);

It is important to set the filter false in setText(...,false) to display the entire list in dropdown and not only the single value.

Use android:text attribute on AutoCompleteTextView like this

<com.google.android.material.textfield.TextInputLayout
                  
                    style="@style/Widget.MaterialComponents.TextInputLayout.FilledBox.ExposedDropdownMenu"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                
                    app:hintTextColor="@color/primary_color_3">

                    <AutoCompleteTextView
                        android:id="@+id/accType_dropdown"
                        android:layout_width="match_parent"
                        android:layout_height="wrap_content"
                        android:text="Select Something"
                        android:backgroundTint="@android:color/transparent"
                        android:inputType="none"
                        android:lineSpacingExtra="5sp"
                        android:textColor="@color/name_primary_color"
                        android:textSize="14sp" />

                </com.google.android.material.textfield.TextInputLayout>
