AutoCompleteTextView doesn't work when I enter first character

Question

My AutoCompleteTextView doesn't work when I enter first character in textbox but starts showing dropdown when I enter second character. What could be the reason?

<AutoCompleteTextView
    android:id="@+id/autocomplete_name"
    android:layout_width="wrap_content"
    android:layout_height="fill_parent"
    android:layout_weight="7"
    android:background="@drawable/edittextback"
    android:ems="10"
    android:textSize="15sp"
    android:hint="@string/codehint"
    android:textColorHint="@color/hintgrey"
    android:dropDownWidth="fill_parent"
    android:paddingRight="30dp"
    android:paddingLeft="10dp"
    android:singleLine="true"
    android:ellipsize="end"
/>

You will need to set the completionThreshold property of your autoCompleteView to 1.

<AutoCompleteTextView 
    android:id="@+id/someID" 
    android:layout_width="200dp"
    android:layout_height="wrap_content"
    android:completionThreshold="1" />

Or for doing it dynamically through code use

mAutoCompleteTextView.setThreshold(1)

Happy Coding :)

If you want after clicking on MaterialAutoCompleteTextView Open the dialog

you must set the completionThreshold value to 0 And inputType value to none.

you can also increase the same field for the minimum number of characters.

don't forget set inputType to text or number

 <com.google.android.material.textfield.MaterialAutoCompleteTextView
                android:layout_width="match_parent"
                android:layout_height="45dp"
                android:completionThreshold="0" <-- This line
                android:ems="10"
                android:inputType="none" />

I hope hep
