[AutoCompleteTextView] Exposed Dropdown Menu not showing items

[philipbrito]

Description:

Exposed Dropdown Menu doesn't show items after user selection and fragment transition.

Following is the basic xml declaration:

<com.google.android.material.textfield.TextInputLayout
    ...
    style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox.ExposedDropdownMenu"
 
         <AutoCompleteTextView
            .... 
            android:id="@+id/dropdown"
            android:dropDownHeight="300dp"
            android:inputType="none" />
</com.google.android.material.textfield.TextInputLayout>

And, the declared code on the fragment (inside onViewCreated()):

    val items = listOf("Material", "Design", "Components", "Android")
    val adapter = ArrayAdapter(requireContext(), R.layout.item_menu, items)
    dropdown.setAdapter(adapter)
    dropdown.setText(items[0], false)

As mentioned here, it was set on AutoCompleteTextView's setText method (dropdown.setText("", false)) the filter parameter as false. However, after navigating to a next fragment and coming back to it, only the pre-selected text is shown on the dropdown.

Fragments are changed using navigation component (v. 2.3.2).

Expected behavior: Dropdown should show all items.

Android API version: Android API 30

Material Library version: 1.3.0-rc01

Device: Emulator - Pixel 4 XL

You can implement this extention on onClickListener to make all list keep showing after it clicked.

fun AutoCompleteTextView.showDropdown(adapter: ArrayAdapter<String>?) {
    if(!TextUtils.isEmpty(this.text.toString())){
        adapter?.filter?.filter(null)
    }
}

And also add focusable="false" to AutoCompleteTextView in xml.

This does seem to work as a temp workaround 🤔 🙏

Currently experiencing the same problem here, does any one have a fix for this?

Temp solution working for me is to move part of the code to onResume():

override fun onResume() {
        super.onResume()

        val arrayAdapter =
            ArrayAdapter(requireContext(), R.layout.menu_list_item, floorEntries)
        binding.tvFloor.setAdapter(arrayAdapter)

        setSelectedFloor()
    }

Same problem on material version 1.4.0 had to implement custom array adapter with custom/no filter

If it is in fragment you better put this extension in onResume, this way filters are canceled automatically.

It's a duplicate of #1464. Unfortunately it's an Android framework issue and I'm trying to push for a workaround on the Material side or AppCompat.

[Leshachok]

Faced the same problem.
Downgrading 'androidx.navigation:navigation-ui-ktx' library from 2.4.2 to version 2.3.5 helped me

Faced the same damn problem, here it solves putting all in onResume, as already written by someone else:

This works perfectly, thank you !

This is still a problem at 2022.12.01 using material:1.7.0
None of the workarounds appear to work in my case

[RasulOs]

Same problem (material:1.4). The problem was solved by putting an ArrayAdapter in the onResume() method.

[Sweeneyliu114514]

As of now (Sept 2023) this bug still exists in material 1.9

[EnriekNP]

this issue still happening for me... in material 1.10.0
