Android: AutoCompleteTextView show suggestions when no text entered -
 I'm using  AutoCompleteTextView , when the user clicks on it, I suggest I want to give it even though it is not a text - but  setThreshold (0)  works exactly like  setThreshold (1)  - so the user is less Must enter less than 1 character. 
This is: "Threshold for 0, 1 is applied when the threshold is less or equal."
 You can show the drop down manually via  showDropDown () , so perhaps you can arrange to show it when you want , < Code> true  returning
