android AutoCompleteTextView white on white Dropdown list

Question

breaking my head here, i have searched online for quite a bit and it seems this was a bug on android before but have not found a solution yet.

I have a AutoCompleteTextView:

autodesignations = (AutoCompleteTextView) findViewById(R.id.main_autocomp);

adapterShapesAuto = new ArrayAdapter<String>(this,android.R.layout.simple_dropdown_item_1line, shapes);

autodesignations.setAdapter(adapterShapes);

the widget works, but the dropdown text is always white text on white background.

I have tried setting the resource for the adapter to several combinations of android's built-in layouts & also my own.

Even pointing it to a TextView resource being also use for a Spinner (which works as expected, black text on white background), but have found no way of making this work, keep getting the same results

Any help?

Answer 1

I had this issue . Fixed it using android.R.layout.select_dialog_item for layout.

Answer 2

So here is the answer for my issue.

As often, this and a context reference are not exactly the same. Maybe because the context reference might be passed down across some activities, whatever.

So I changed that line (which is included inside a onClickListener) where 'context' is retrieved during onCreate() by getApplicationContext();

adapterListModele = new ArrayAdapter<String>(context, android.R.layout.select_dialog_item, listModeleNom);

into the following line where I used a this from my class :

adapterListModele = new ArrayAdapter<String>(AncestorVehicule.this, android.R.layout.select_dialog_item, listModeleNom);

And it works ! No more white font.

I tested it outside the onclicklistener callback and noticed 2 things :

• using same 'context' variable did make the drop down to be displayed in white
• sticking to 'this' avoids the issue.

Hope it helps someone else.
