Android Spinner 文字居中、其下拉窗口文字居中，自定义Spinn

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="fill_parent"
android:layout_width="fill_parent"
android:textColor="@color/colorBlue"
android:textSize="16sp"
android:gravity="center"/>

2.item_dialogspinselect(下拉窗口样式)

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="40dp"
android:layout_width="fill_parent"
android:textColor="@color/colorBlue"
android:textSize="18sp"
android:background="@drawable/border"
android:gravity="center"/>

二、代码引用资源文件

List<SpinnerData> liststates = new ArrayList<SpinnerData>();

ArrayAdapter adap = new ArrayAdapter<SpinnerData>(context, R.layout.item_spinselect, liststates);
adap.setDropDownViewResource(R.layout.item_dialogspinselect);
spinner.setAdapter(adap);

另一种方法：重写Adapter;
