Android 自定义 spinner (背景、字体颜色)

1、准备两张图片，并做好9.png

2、在drawable中定义spinner_selector.xml

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

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

    <item android:state_pressed="true"   

        android:drawable="@drawable/spinner_press" /><!--按下时效果-->  

    <item android:state_pressed="false"  

        android:drawable="@drawable/spinner" /><!--默认效果-->   

</selector>

3、style中定义

    <!-- spinner -->

    <style name="spinner_style">

    <item name="android:background">@drawable/spinner_selector</item>

    <item name="android:paddingLeft">5dip</item>

    </style>

4、调用

<Spinner

    android:id="@+id/field_item_spinner_content"

    style="@style/spinner_style"

    android:layout_width="fill_parent"

    android:layout_height="wrap_content"

    android:animationCache="true"

    android:drawSelectorOnTop="true" />

5、在layout中定义simple_spinner_item.xml

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

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

    android:id="@android:id/text1"

    android:paddingLeft="5dip"

    android:paddingRight="5dip"

    android:gravity="center_vertical"

    android:textColor="#808080"

    android:singleLine="true"

    android:layout_width="fill_parent"

    android:layout_height="wrap_content"

    />

6、java代码

ArrayAdapter<String> adapter = new ArrayAdapter<String>(mContext, R.layout.simple_spinner_item);

String level[] = getResources().getStringArray(R.array.affair_level);//资源文件

for (int i = 0; i < level.length; i++) {

adapter.add(level[i]);

}

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

spinner.setAdapter(adapter);
