从 AutoCompleteTextView 中删除下拉箭头

Question

I want to remove dropdown arrow which is created by AutoCompleteTextView when I use TextInputLayout and use Style: ExposedDropdownMenu

Below is my code:

<com.google.android.material.textfield.TextInputLayout
        android:layout_marginTop="10dp"
        style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox.ExposedDropdownMenu"
        android:hint="Marital Status"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:boxStrokeColor="@color/colorPrimaryDark">

        <AutoCompleteTextView
            android:background="@null"
            android:focusable="false"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:id="@+id/edt_marital" />
    </com.google.android.material.textfield.TextInputLayout>

If you would like to avoid the dropdown icon just use the app:endIconMode attribute.

<com.google.android.material.textfield.TextInputLayout
      style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox.ExposedDropdownMenu"
      app:endIconMode="none"
      ...>

Hello guys, after having searched a lot and found little. I was trying to achieve how I wanted and I wanted to share the experience and result with you. As the same Material Design documentation says.

A result Image Dropdown Menu similar to a Spinner, following the documentation. Next code:

<com.google.android.material.textfield.TextInputLayout
                android:id="@+id/txtAnswer"
                style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox.ExposedDropdownMenu"
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:layout_marginTop="@dimen/margin_top_15dp"
                android:layout_marginEnd="10dp"
                app:endIconDrawable="@drawable/ic_arrow_down"
                app:hintTextAppearance="@style/styleFilterLabelLatoRegular"
                app:layout_constraintEnd_toStartOf="@+id/txtAssignedTo"
                app:layout_constraintStart_toStartOf="@+id/guideLineBegin"
                app:layout_constraintTop_toBottomOf="@+id/txtSearchQuestionnaire">

                <AutoCompleteTextView
                    android:id="@+id/actvTypesAnswer"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:inputType="none"
                    android:hint="@string/text_answer" />

Now a result as expected from an AutoCompleteTextView Image AutoCompleteTextView . Code xml.

<com.google.android.material.textfield.TextInputLayout
                android:id="@+id/txtSearchQuestionnaire"
                style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox.ExposedDropdownMenu"
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:layout_marginTop="@dimen/margin_top_15dp"
                app:endIconMode="none"
                app:hintTextAppearance="@style/styleFilterLabelLatoRegular"
                app:layout_constraintEnd_toEndOf="@id/guideLineEnd"
                app:layout_constraintStart_toStartOf="@+id/guideLineBegin"
                app:layout_constraintTop_toBottomOf="@+id/txtPeriodActivation">

                <AutoCompleteTextView
                    android:id="@+id/actvNameQuestionnaire"
                    style="@style/textAppearanceSettingInputEdittextFilter.Enabled"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:drawableEnd="@drawable/ic_search"
                    android:hint="@string/text_search_name_questionnaire" />

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

The only changes were to add the attribute app: endIconMode = "none" in TextInputLayout and in the AutoCompleteTextView the attribute android: drawableEnd = "@ drawable / ic_search"

Excuse my level of English!!
