Hi, since the menu uses an So you'd do something like: |

changed the title
note that this won't survive configuration changes. after a configuration change the item is selected again, but with filtering. items not matching the filter aren't visible anymore. |
|
@wondering639 Anyway to the make filter visible on configuration change ? I am facing similar issue when I go back to the fragments with navigation components, the filter options are not visible anymore. |
|
@blacpythoz I solved (workaround) it by creating a non filtering adapter as described in this article: https://medium.com/@rmirabelle/there-is-no-material-design-spinner-for-android-3261b7c77da8 |
|
@wondering639 is right. setting filtering to false doesn't survive configuration change. I doubt that this is intended behavior. |

@wondering639 I try to explain better. To select a default value you have to use: After a rotation or a configuration change the value is still visible but with filtering. Items not matching the filter aren't visible anymore. It happens because the

I have a same bug when i back via navigation component on my fragment where i allready select some item in dropdown |

FIX: All the values will be visible after the device rotation and also the selected value will be displayed. public class TextInputDropDownMenu extends AppCompatAutoCompleteTextView {
public TextInputDropDownMenu(@NonNull Context context) {
super(context);
}
public TextInputDropDownMenu(@NonNull Context context, @Nullable AttributeSet attrs) {
super(context, attrs);
}
public TextInputDropDownMenu(@NonNull Context context, @Nullable AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
}
{
setInputType(InputType.TYPE_NULL);
}
@Override
public boolean getFreezesText() {
return false;
}
@Override
public Parcelable onSaveInstanceState() {
Parcelable parcelable = super.onSaveInstanceState();
if (TextUtils.isEmpty(getText())) {
return parcelable;
}
CustomSavedState customSavedState = new CustomSavedState(parcelable);
customSavedState.text = getText().toString();
return customSavedState;
}
@Override
public void onRestoreInstanceState(Parcelable state) {
if (!(state instanceof CustomSavedState)) {
super.onRestoreInstanceState(state);
return;
}
CustomSavedState customSavedState = (CustomSavedState) state;
setText(customSavedState.text, false);
super.onRestoreInstanceState(customSavedState.getSuperState());
}
private static final class CustomSavedState extends BaseSavedState {
private String text;
public CustomSavedState(Parcelable superState) {
super(superState);
}
public CustomSavedState(Parcel source) {
super(source);
text = source.readString();
}
@Override
public void writeToParcel(Parcel out, int flags) {
super.writeToParcel(out, flags);
out.writeString(text);
}
private static final Creator<CustomSavedState> CREATOR = new Creator<CustomSavedState>() {
@Override
public CustomSavedState createFromParcel(Parcel source) {
return new CustomSavedState(source);
}
@Override
public CustomSavedState[] newArray(int size) {
return new CustomSavedState[size];
}
};
}

Did anyone manage to get a fix for this? |
|
We are working with the Framework and Androidx team to figure out a good solution of this. (List gets filtered after configuration change.) The tracking issue is here: #1464 |
|
Has there been a fix for this?
I appreciate the fast response. My problem was that the filtering got triggered even if I set it to false. In other words, the text was there on application startup, but there was no way to change it again (I didn't have similar values). Using |
|
Can you provide more details? Is your issue different from the one after configuration change? |
|
I'm not sure what you mean by "configuration change" but I was trying to set a default value for my AutoCompleteTextView. The following was not working:
The behavior I got: The text is set properly, but if I click again on the DropDownMenu, it doesn't open. I'm guessing because the filter was ON although I'm explicitly setting it to false as you can see. Doing this: Fixed the problem. |
|
I meant after the view is recreated by the framework. Are you setting a default value right after the view is created/inflated? |
|
I haven't tried that actually. And to answer your question, yes, that's what I'm doing. Is that the wrong way to go by it? |
|
I think that might be a bug on our end. I need to check. : ) |
|
Hi @Imadlekal - I cannot reproduce what you said. Can you provide a minimal repro app so we can debug? Or at least more detailed code snippet regarding how you inflate and set up your AutoCompleteTextView. |
|
I'll close this issue for now due to no further info available. Please feel free to reopen it with a repro. |
