自定义Spinner

java逻辑代码：

        /* parity */
        paritySpinner = (Spinner) findViewById(R.id.parityValue);
        ArrayAdapter<CharSequence> parityAdapter = ArrayAdapter.createFromResource(this, R.array.parity,
                        R.layout.my_spinner_textview);
        parityAdapter.setDropDownViewResource(R.layout.my_spinner_textview);
        paritySpinner.setAdapter(parityAdapter);
        paritySpinner.setGravity(0x11);
        /* default is none */
        parity = 0;

监听：

    /* set the adapter listeners for parity */
    paritySpinner.setOnItemSelectedListener(new MyOnParitySelectedListener());

    public class MyOnParitySelectedListener implements OnItemSelectedListener {
        public void onItemSelected(AdapterView<?> parent, View view, int pos,
                long id) {

            String parityString = new String(parent.getItemAtPosition(pos).toString());
            if (parityString.compareTo("None") == 0) {
                parity = 0;
            }

            if (parityString.compareTo("Odd") == 0) {
                parity = 1;
            }

            if (parityString.compareTo("Even") == 0) {
                parity = 2;
            }

            if (parityString.compareTo("Mark") == 0) {
                parity = 3;
            }

            if (parityString.compareTo("Space") == 0) {
                parity = 4;
            }
        }

        public void onNothingSelected(AdapterView<?> parent) { // Do nothing. }}
        }
    }

布局文件Spinner：R.id.parityValue

<Spinner
                android:id="@+id/parityValue"
                android:layout_width="fill_parent"
                android:layout_height="fill_parent"
                android:layout_marginBottom="5dp"
                android:layout_marginLeft="5dp"
                android:layout_marginRight="5dp"
                android:layout_marginTop="5dp"
                android:layout_weight="1"
                android:background="#708070"
                android:gravity="center_horizontal|center"
                android:inputType="none" />

下拉布局：R.layout.my_spinner_textview

<?xml version="1.0" encoding="utf-8"?>
<TextView
    xmlns:android="http://schemas.android.com/apk/res/android"
    style="?android:attr/spinnerItemStyle"
    android:layout_width="fill_parent"
    android:layout_height="35dp"
    android:gravity="center" />

数据源:R.array.parity

    <string-array name="parity">        
        <item>None</item>        
        <item>Odd</item>
        <item>Even</item>
        <item >Mark</item>
        <item >Space</item>
    </string-array>

效果图：

这种样式需要设置：

       android:spinnerMode="dropdown"

默认：

android:spinnerMode="dialog"
