android工程中资源模块划分

android app中的资源管理：所有的资源都位于res目录下。

1，图片资源（drawable-hdpi和drawable-mdpi）

不像游戏，所有图片都是在assets下面的，app中为了屏幕适配，图片资源是在drawable-hdpi和drawable-mdpi下面的。

2，按钮按下各种状态。（drawable）

实例

news_collect_btn_selector.xml

<?xml version="1.0" encoding="UTF-8"?><selectorxmlns:android="http://schemas.android.com/apk/res/android"><itemandroid:state_focused="true"android:drawable="@drawable/news_collect_btn_press" /><itemandroid:state_pressed="true"android:drawable="@drawable/news_collect_btn_press" /><itemandroid:drawable="@drawable/news_collect_btn" /></selector>

news_reply_post_btn_selector.xml

<?xml version="1.0" encoding="UTF-8"?><selectorxmlns:android="http://schemas.android.com/apk/res/android"><itemandroid:state_enabled="false"android:drawable="@drawable/news_reply_post_btn_up" /><itemandroid:state_pressed="true"android:drawable="@drawable/news_reply_post_btn_down" /><itemandroid:state_focused="true"android:drawable="@drawable/news_reply_post_btn_down" /></selector>

其中@drabable下面的引用是drawable-hdpi和drawable-mdpi下面的图片资源。

3，颜色（color）

category_item_title_selector.xml

<?xml version="1.0" encoding="utf-8"?><selectorxmlns:android="http://schemas.android.com/apk/res/android"><itemandroid:state_pressed="true"android:color="#ffffffff" /><itemandroid:state_focused="true"android:color="#ffffffff" /><itemandroid:state_selected="true"android:color="#ffffffff" /><itemandroid:color="#ffadb2ad" /></selector>

newslist_item_source_selector.xml

<?xml version="1.0" encoding="utf-8"?><selectorxmlns:android="http://schemas.android.com/apk/res/android"><itemandroid:state_pressed="false"android:color="#ff878787" /><itemandroid:state_pressed="true"android:color="#ffbcbcbc" /><itemandroid:state_focused="true"android:color="#ffbcbcbc" /><itemandroid:color="#ff878787" /></selector>

4，动画（anim）
