Adapter has no effect on spinner

Question

Making spinner with custom dropdown list

I want to make a Spinner in android which will have the following dropdown list style:

My onCreate method does

 ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(
                this, R.array.day, android.R.layout.simple_spinner_item);

and

setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item)

to make the previous image's spinner dropdown list.

  protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

       Spinner spinner = (Spinner) findViewById(R.id.spinner);

        ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(
                this, R.array.day, android.R.layout.simple_spinner_item);

        adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        spinner.setAdapter(adapter);

    }

I followed the instructions from this site . But I don't get the same dropdown list. The setDropDownViewResource and the adapter have no effect.

The only difference i find with the instructions is that the example's style is "android:Theme.Light", while my theme style is Theme.AppCompat.Light . So, i wonder if the AppCompat is the problem.

try this to solve your issue

xml:

<Spinner
        android:id="@+id/spinner1"
        android:layout_width="275dp"
        android:layout_height="50dp"
        android:layout_gravity="center"
        android:spinnerMode="dropdown"
        style="@android:style/Widget.Spinner"
        android:layout_marginTop="20dp" />

code:

ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this, R.array.day, android.R.layout.simple_spinner_item);


adapter.setDropDownViewResource(android.R.layout.select_dialog_singlechoie);
spinner.setAdapter(adapter);
