Answer 1

Try below code to do so. Change style attribute in your spinner list item layout to textViewStyle as below

<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/text1"
    style="?android:attr/textViewStyle"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:singleLine="false"
    android:textAlignment="inherit"
    android:textAppearance="?android:attr/textAppearanceMedium" />

Answer 2

You can also remove the padding of spinner in xml

Only need to set padding to 0dp.

    <Spinner
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="left"
        android:padding="0dp"     
        android:id="@+id/my_spinner">

Answer 3

Try this,

1. Create custom layout(as you need) for spinner row.

2. inflate the layout when you set the data adapter to the spinner.

Answer 4

This array adapter removes left padding in Android Spinner.

Kotlin version:

open class NoPaddingArrayAdapter<T>(context: Context, layoutId: Int, items: List<T>?) : ArrayAdapter<T>(context, layoutId, items) {

    override fun getView(position: Int, convertView: View?, parent: ViewGroup?): View? {
        val view = super.getView(position, convertView, parent)
        view.setPadding(0,view.paddingTop,view.paddingRight,view.paddingBottom)
        return view
    }
}

Answer 5

If you are using custom adapter, then try setting padding in getView() :

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    View view = super.getView(position, convertView, parent);
    view.setPadding(0, view.getPaddingTop(), view.getPaddingRight(), view.getPaddingBottom());
    return view;
}

Answer 6

You can customize your own Spinner via Nine patch and specify padding
