i have 2 AutoCompleteTextview how to populate both

Question

I made 3 AutoCompleteTextview but when I populate it, only first one is populated and the other one is not working.

Note: I am using custom AutoCompleteTextview to resolve the threshold with 1 issue.

my layout file:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"

    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context=".activities.ActivityProjectInfo2Preference">

    <!--toolbar-->
    <include layout="@layout/toolbar" />

        <LinearLayout

                    android:layout_height="wrap_content"/>

            </com.google.android.material.textfield.TextInputLayout>

</LinearLayout>

my java code :

String[] styleArray = getResources().getStringArray(R.array.entries_style_preference);
        ArrayAdapter styleAdapter = new ArrayAdapter(this,
                R.layout.dropdown_menu_popup_item,
                styleArray);
        styleAdapter.getFilter();
        mStylePrefSpinner.setAdapter(styleAdapter);

        String[] colorArray = getResources().getStringArray(R.array.entries_colors_preference);
        ArrayAdapter colorAdapter = new ArrayAdapter(this,
                R.layout.dropdown_menu_popup_item,
                colorArray);
        colorAdapter.getFilter();
        mStylePrefSpinner.setAdapter(colorAdapter);

        String[] finishArray = getResources().getStringArray(R.array.entries_finish_preference);
        ArrayAdapter finishAdapter = new ArrayAdapter(this,
                R.layout.dropdown_menu_popup_item,
                finishArray);
        finishAdapter.getFilter();
        mStylePrefSpinner.setAdapter(finishAdapter);

I tried it one by one then it started to work, but when i write code for all of the three, then only one of them is working.

Answer 1

You are assigning the adapter to the same binded property mStylePrefSpinner all the times:

...
mStylePrefSpinner.setAdapter(styleAdapter);
...
mStylePrefSpinner.setAdapter(colorAdapter);
...
mStylePrefSpinner.setAdapter(finishAdapter);

You should set it to each binded property. Assuming they are mStylePrefSpinner, mStyleColorSpinner & mStyleFinishSpinner:

...
mStylePrefSpinner.setAdapter(styleAdapter);
...
mStyleColorSpinner.setAdapter(colorAdapter);
...
mStyleFinishSpinner.setAdapter(finishAdapter);
