android 中resources管理(主要存在于res/value文件夹中)

http://www.cnblogs.com/zhangs1986/p/3624482.html#top


定义:

dimen.xml:主要用于设置像素默认值

<resources>

 res/values/dimens.xml

<dimen name="sp_12">12sp</dimen>
<dimen name="sp_13">13sp</dimen>

 <dimen name="dip_40">40dip</dimen>
 <dimen name="dip_45">45dip</dimen>

</resources>

代码使用:

int width=getContext().getResources().getDimension(R.dimen.tab_width);

xml文件使用:

android:layout_width="@dimen/tab_width"

color.xml设置颜色

<?xml version="1.0" encoding="utf-8"?>
<resources>
<item type="drawable" name="main_background">#FFE7E7E7</item>
<item type="drawable" name="newslist_item_background">#FFE7E7E7</item>

<item type="color" name="category_title_normal_background">#FFADB2AD</item>
<item type="color" name="gold">#b89766</item>
<item type="color" name="transparent">#000000</item>
<item type="color" name="textcolor">#FFFFFF</item>
<item type="color" name="bgcolor">#000000</item>
</resources>

<color name="text_color_default">#ff000000</color>
<color name="text_color_pressed">#ffffffff</color>
</resources>

调用color标签:android:background="@color/red" @color/是调用res/下的匹配的color标签 

也可以将color标签嵌入到selector的item标签中使用  

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true"
android:color="@color/red"/>
<item android:color="@color/green" />
</selector>

 

代码设置color方法:

testview.setTextColor(Color.parseColor("FFFFFF")); 

testview.setTextColor(Color.GRAY);

tv.setTextColor(Color.rgb(255255255)); 

testview.setTextColor(getContext().getResources().getColor(R.color.my_color));

 

 

array.xml

<resources>
    <declare-styleable name="DragSort">
        <attr name="collapsed_height" format="dimension" />
        <attr name="drag_scroll_start" format="float" />
        <attr name="max_drag_scroll_speed" format="float" />
        <attr name="float_background_color" format="color" />
        <attr name="remove_mode">
            <enum name="clickRemove" value="0" />
            <enum name="flingRemove" value="1" />
        </attr>
        <attr name="track_drag_sort" format="boolean" />
        <attr name="float_alpha" format="float" />
        <attr name="slide_shuffle_speed" format="float" />
        <attr name="remove_animation_duration" format="integer" />
        <attr name="drop_animation_duration" format="integer" />
        <attr name="drag_enabled" format="boolean" />
        <attr name="sort_enabled" format="boolean" />
        <attr name="remove_enabled" format="boolean" />
        <attr name="drag_start_mode">
            <enum name="onDown" value="0" />
            <enum name="onMove" value="1" />
            <enum name="onLongPress" value="2" />
        </attr>
        <attr name="drag_handle_id" format="integer" />
        <attr name="fling_handle_id" format="integer" />
        <attr name="click_remove_id" format="integer" />
        <attr name="use_default_controller" format="boolean" />
    </declare-styleable>

</resources>

代码使用:

 TypedArray array = getContext().obtainStyledAttributes(attrs, R.styleable.DragSort, 0, 0);

         mItemHeight = Math.max(1, array.getDimensionPixelSize(R.styleable.DragSortListView_collapsed_height, 1));

         mTrackDragSort = array.getBoolean( R.styleable.DragSortListView_track_drag_sort, false);

xml使用:

    <ListPreference
     android:title="@string/page_animation"
     android:defaultValue="@string/default_page_animation"
     android:entries="@array/page_animation_labels"
     android:entryValues="@array/page_animations"
     android:key="pageAnimation"
     />

 

strings.xml:主要设置文本

<resources>

 <string name="button_confirm">确定</string>     
 <string name="button_cancel">取消</string>   

 <string-array name="page_animations">
  <item>100</item>
  <item>0</item>
  <item>1</item>
  <item>2</item>
  <item>3</item>
 </string-array>

</resources>

代码使用:

testview.setText(getString(R.string.button_confirm));

xml使用:

android:text="@string/button_confirm"

 

风格style与主题theme区别:

1:style主要用于View,theme主要用于Activity以及Application

2、style主要用于设置View的属性,theme主要用设置Activity的样式如是:否全屏

3、style与theme都是以<style><item>文本</item></style>创建,只是item的内容不一样

style定义:

style.xml文件

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

 <style name="TitleStyle"> 

  <item name="android:textSize">18sp</item>

  <item name="android:textColor">#ec9237</item>

</style>

<style name="Title" parent="@style/TitleStyle"> (继承TitleStyle属性)

  <item name="android:textSize">5sp</item> 

</style> 

 </resources>

代码使用:

 

xml使用:

<EditText android:layout_height="wrap_content"

android:text="EditText"

style="@style/Title" 

android:layout_width="fill_parent" 

android:id="@+id/editText1" />

-----------------------------------------------

theme:

style.xml

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

<resources>

  <style name="theme1">

    <item name="android:windowNoTitle">true</item> 

    <item name="android:windowFullscreen">?android:windowNoTitle</item> 

  </style> 

  <style name="theme2.a">

    <item name="android:windowNoTitle">true</item> 

    <item name="android:windowFullscreen">?android:windowNoTitle</item> 

  </style> 

</resources> 

代码使用:

注意:setTheme应该在setContentView之前调用。

setTeme(R.theme.theme1);/setTeme(R.style.theme1)

setContentView(R.layout.main);

 

xml使用主题:

<application

  android:icon="@drawable/icon" android:label="@string/app_name" 

  android:theme="@style/theme1">

  <activity

    android:name=".MessageShowActivity" android:label="@string/app_name" 

    android:windowSoftInputMode="adjustPan" android:screenOrientation="portrait"

    android:theme="@style/theme2">

  </activity>

</application> 

---------------------------------

android的selector是在drawable/xxx.xml中创建的:

selector:主要用设置view点击选中显示效果

<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item
  android:color="hex_color"
  android:state_pressed=["true" | "false"]
  android:state_focused=["true" | "false"]
  android:state_selected=["true" | "false"]
  android:state_checkable=["true" | "false"]
  android:state_checked=["true" | "false"]
  android:state_enabled=["true" | "false"]
  android:state_window_focused=["true" | "false"] />
</selector>

android:drawable 放一个drawable资源
android:state_pressed 是否按下,如一个按钮触摸或者点击。
android:state_focused 是否取得焦点,比如用户选择了一个文本框。
android:state_hovered 光标是否悬停,通常与focused state相同,它是4.0的新特性
android:state_selected 被选中,它与focus state并不完全一样,如一个list view 被选中的时候,它里面的各个子组件可能通过方向键,被选中了。
android:state_checkable 组件是否能被check。如:RadioButton是可以被check的。
android:state_checked 被checked了,如:一个RadioButton可以被check了。
android:state_enabled 能够接受触摸或者点击事件
android:state_activated 被激活(这个麻烦举个例子,不是特明白)
android:state_window_focused 应用程序是否在前台,当有通知栏被拉下来或者一个对话框弹出的时候应用程序就不在前台了

-------

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

  <item android:state_window_focused="false" android:drawable="@drawable/pic1" /><!-- 没有焦点时的背景图片-->
  <item android:state_focused="true" android:state_pressed="true" android:drawable="@drawable/pic2" /><!-- 非触摸模式下获得焦点并单击时的背景图片-->
  <item android:state_focused="false" android:state_pressed="true" android:drawable="@drawable/pic3" /><!-- 触摸模式下单击时的背景图片-->
  <item android:state_selected="true" android:drawable="@drawable/pic4" /><!--选中时的图片背景-->
  <item android:state_focused="true" android:drawable="@drawable/pic5" /><!--获得焦点时的图片背景-->
 </selector>

 

在xml中使用示例:

res/color/button_text.xml

<?xml version="1.0" encoding="utf-8"?>
<selectorxmlns:android="http://schemas.android.com/apk/res/android">
   
<item
      
android:state_pressed="true"
        android:color="#ffff0000"/><!-- pressed -->
   <item
      android:state_focused
="true"
        android:color="#ff0000ff"/><!-- focused -->
   <itemandroid:color="#ff000000"/><!-- default -->
</selector>
<Button
  android:layout_width="fill_parent"
  android:layout_height="wrap_content"
  
android:text="@string/button_text"
  
android:textColor="@color/button_text"/>
