Android custom drop down view with dynamic list
I have a problem with filling android:entries with String from my ViewModel. Code looks like that:
attrs.xml
<declare-styleable name="AutoCompleteDropDown">
<attr name="android:entries" />
</declare-styleable>
My custom dropdown, AutoCompleteDropDown
public class AutoCompleteDropDown extends AppCompatAutoCompleteTextView {
public AutoCompleteDropDown(Context context, AttributeSet attributes) {
super(context, attributes);
TypedArray a = context.getTheme().obtainStyledAttributes(attributes, R.styleable.AutoCompleteDropDown, 0, 0);
CharSequence entries = a.getTextArray(R.styleable.AutoCompleteDropDown_android_entries);
ArrayAdapter<CharSequence> adapter = new ArrayAdapter<>(context, android.R.layout.simple_dropdown_item_1line, entries);
setAdapter(adapter);
}
...
ViewModel
...
private String genders;
public String getGenders() {
return genders;
}
public void setGenders(String genders) {
this.genders = genders;
}
...
genders are filled in ViewModel constructor:
genders = dataRepository.getGenders();
xml file
<AutoCompleteDropDown
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="@={vm.title}"
android:entries="@{vm.genders}"
bind:addTextChangedListener="@{vm.titleValidationChangeListener}"/>
ViewModel is binded correctly, i'm using it many times in that xml file. When i try to run the app i'm getting:
Cannot find the setter for attribute 'android:entries' with parameter
type java.lang.String on AutoCompleteDropDown
It works when i use android:entries="@array/genders" but i need this list to be dynamic. Project is in MVVM pattern. Appreciate any help :)

You can use BindingAdapter for this. Like :
@BindingAdapter("entries")
public static void entries(AutoCompleteDropDown view, String array) {
view.updateData(array);
}
updateData it's method which you must create in your AutoCompleteDropDown.
And in xml it's using same
app:entries="@{vm.genders}"
