Spinner的簡單應用

1、

private List<String> list;
private ArrayAdapter<String> arrayAdapter;
private void initview() {
    List<String> listsex = new ArrayList<>();
    listsex.add("男");
    listsex.add("女");
    ArrayAdapter<String> arrysex = new ArrayAdapter<String>(this, R.layout.myspinner, listsex);
    arrysex.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    main_myuser_new_et_sex.setAdapter(arrysex);
}

2、自定義字體顏色、大小等，新建一個xml、myspinner.xml：

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/text1"
    android:gravity="left"
    android:textStyle="bold"
    android:textColor="#FFF"
    android:singleLine="true"
    android:textSize="18sp"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:ellipsize="marquee" /> 

3、獲取spinner值：

sex = (String) main_myuser_new_et_sex.getSelectedItem();
