自定义spinner

java代码：

arrayadapter = ArrayAdapter.createFromResource(this, R.array.grade_list, R.layout.spinner_text)":

arrayadapter.setDropDownViewResource(R.layout.spinner_item);

xml:

在res 的layout中建spinner_text.xml和spinner_item.xml文件，注意id 都要设为"@android:id/text1

spinner_text.xml:

<?xml version="1.0" encoding="utf-8"?>

<TextView xmlns:android="http://schemas.android.com/apk/res/android"

android:id="@android:id/text1"

style="?android:attr/spinnerItemStyle"

android:singleLine="true"

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:ellipsize="marquee"

android:textColor="@color/bottombar_textcolor"

android:textAlignment="inherit"/>

spinner_item.xml:

<?xml version="1.0" encoding="utf-8"?>

<TextView xmlns:android="http://schemas.android.com/apk/res/android"

android:id="@android:id/text1"

android:layout_width="match_parent"

android:layout_height="42dp"

android:gravity="center_vertical|center_horizontal"

android:textSize="16sp"

android:textColor="@color/bottombar_textcolor"

android:background="@drawable/spinner_item_bgchange">

</TextView>
