Just add this to your adapter.

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

simple_spinner_dropdown_item is the default android layout and should not be edited. Btw. changing anything inside has no effect for my spinners. Better to add android:minHeight="80dp" to your Spinner section in layout xml – Darksymphony Nov 25 '18 at 19:26
if you use this, you cant edit your layout... and if you give your layout id it also not work... this not solve error – Ucdemir Aug 31 '21 at 18:25

Maybe it can help..

ArrayAdapter<String> yourSpinnerAdapter = new ArrayAdapter<String>(this,
                R.layout.spinner_item, yourItem) {

        @Override
        public View getDropDownView(int position, View convertView,
                ViewGroup parent) {
            convertView = super.getDropDownView(position, convertView,
                    parent);

            convertView.setVisibility(View.VISIBLE);
            ViewGroup.LayoutParams p = convertView.getLayoutParams();
            p.height = 100; // set the height
            convertView.setLayoutParams(p);

            return convertView;
        }
    };

A perfect solution, effects only the drop down elements and not the text view of the selected item. — Benjamin James Drury, Nov 23 '18 at 23:47

In loginrowspinner.xml, add android:minHeight="48dp" to TextView element.

 <TextView 
     ...
     android:id="@+id/textViewRowFacility"
     android:minHeight="48dp" />

Create your own textview in layout folder like this which will be populated in dropdown popup

<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/text1"
style="?android:attr/spinnerItemStyle"
android:layout_width="match_parent"
android:layout_height="60dp"
android:gravity="center_vertical"
android:paddingLeft="20dp"
android:ellipsize="marquee"
android:singleLine="true"
android:textSize="18sp"
android:textAlignment="inherit" />

Note I have provided

android:layout_height="60dp"

and

android:paddingLeft="20dp"

and use this for your spinner, like this

Spinner dropdown = (Spinner)findViewById(R.id.sosMode);
String[] items = new String[]{"Date", "Travelling alone"};
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, R.layout.custom_dropdown_list, items);
dropdown.setAdapter(adapter);

this works for me :)

`layout_height` was what I was looking for to change the height of the spinner.. thanks! — Renier, Jan 31 '19 at 08:52

You can try using dps.

@Override   
public View getDropDownView(int position, View convertView, ViewGroup parent) {

    LayoutInflater inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

    TextView textview = (TextView)inflater.inflate(android.R.layout.simple_spinner_item, null);

    textview.setText(alOpcion.get(position).getOpcionName());

    DisplayMetrics metrics = parent.getResources().getDisplayMetrics();
    float dp = 40f;
    float fpixels = metrics.density * dp;
    int pixels = (int) (fpixels + 0.5f);

    textview.setHeight(pixels);

    return textview;
}

Have you tried something like android:layout_height="30dp" instead of fill_parent for either of those elements in loginrowspinner.xml?

add this in your adapter : convertView.setMinimumHeight(60); which works for me.

//This might also help:

    adapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, dataForAdapter) {


        @Override
        public View getDropDownView(int position, View convertView, ViewGroup parent) {
            View v = super.getView(position, convertView, parent);
            v.setMinimumHeight((int) (40*cx.getResources().getDisplayMetrics().density));
            v.setBackgroundColor(Color.rgb(222, 222, 222));

Could you please explain '`40*cx.getResources().getDisplayMetrics().density`' ? – backslashN Sep 19 '17 at 07:30
@backslashN, when writing Java code for Android, you can't use dp units and have to specify in pixels instead (unlike XML, which accepts dp also). If you set 40px for all cases, the height will still look small on screens with a lot of pixels. That's why we use this code to take the current device density into account – kit Feb 15 '18 at 10:41

Override method in ArrayAdapter class

@Override
public View getDropDownView(int position, @Nullable View convertView, @NonNull ViewGroup parent) {
    View view = super.getDropDownView(position, convertView, parent);
    view.getLayoutParams().height = 50;
    return view;
}

Got stuck in same problem.Found following solution to be working for me:

 if (Build.VERSION.SDK_INT > Build.VERSION_CODES.LOLLIPOP_MR1) {
        setSpinnerDropDownHeight()
    } else {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
            mBinding?.included?.spinn?.getViewTreeObserver()?.addOnGlobalLayoutListener(object : ViewTreeObserver.OnGlobalLayoutListener {
                @RequiresApi(Build.VERSION_CODES.JELLY_BEAN)
                override fun onGlobalLayout() {
                    mBinding?.included?.spinn?.dropDownVerticalOffset = mBinding?.included?.spinn?.getDropDownVerticalOffset()!! + mBinding?.included?.spinn?.getHeight()!!
                    mBinding?.included?.spinn?.viewTreeObserver!!.removeOnGlobalLayoutListener(this)
                }
            })

            mBinding?.included?.spinn?.dropDownVerticalOffset = 10
        }
    }

Hope it helps someone!!!!

Thanks

As people say, best way is to add

    android:minHeight="48dp"

to .xml. But if you want to do it programatically use:

    mspinner.setMinimumHeight(48);

being mspinner the name of your spinner and 48 the new height of the option.
