         android:layout_width="400dip"
         android:layout_height="50dip"
         android:layout_alignLeft="@+id/lpassword"
         android:layout_below="@+id/lpassword"
         android:layout_marginTop="32dip"            
         android:background="@drawable/location" 
         android:paddingLeft="10dip"               
         android:dropDownWidth="@style/dropDown"  
         android:minHeight="40dip"

如何改变任何想法下降的高度..

Answer 1

只需将其添加到适配器即可.

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

Answer 2

在loginrowspinner.xml中,添加android:minHeight="48dp"到TextView元素.

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

Answer 3

也许它可以帮助..

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;
        }
    };

您是否尝试过类似的方法android:layout_height="30dp"来fill_parent替代loginrowspinner.xml 中的任何一个元素？
