Answer 1

Just add this to your adapter.

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

Solingen

...so clever solution :) – Dubbin

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 – Keyek

if you use this, you cant edit your layout... and if you give your layout id it also not work... this not solve error – Trophoplasm

Answer 2

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. – Exurbanite

Answer 3

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

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

Distrain

Where that TextView comes from in Spinner? – Auberta

this is not work when there two kind layout type – Trophoplasm

Answer 4

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 :)

Answer 5

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;
}

Answer 6

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

Answer 8

//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));


            return v;
        }

    };

Diclinous

Could you please explain '40*cx.getResources().getDisplayMetrics().density' ? – Liebermann

@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 – Cranny

Answer 9

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;
}

It crash java.lang.IllegalStateException: ArrayAdapter requires the resource ID to be a TextView" – Trophoplasm

Answer 10

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

Answer 11

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.
