android 中resources管理
主要存在于res/value文件夹中 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="white">#FFFFFFFF</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> 或 <?xml version="1.0" encoding="UTF-8"?> <resources> <color name="contents_text">#ff000000</color> <color name="encode_view">#ffffffff</color> <color name="possible_result_points">#c0ffff00</color> <color name="result_points">#c000ff00</color> <color name="result_text">#ffffffff</color> <color name="result_view">#b0000000</color> <color name="share_text">#ff000000</color> <color name="status_view">#50000000</color> <color name="status_text">#ffffffff</color> <color name="transparent">#00000000</color> <color name="viewfinder_frame">#ff000000</color> <color name="viewfinder_laser">#ffff0000</color> <color name="viewfinder_mask">#60000000</color> <color name="red">#ffff0000</color> <color name="blue">#ff3590c4</color> <color name="green">#7700ff00</color> <color name="yellow">#ffff7000</color> <color name="screen_background_white">#00ffffff</color> <color name="translucent_background">#00000000</color> <color name="white_background">#00ffffff</color> <color name="gray_background">#fff7f7f7</color> <color name="solid_red">#ffff0000</color> <color name="solid_while">#ff888888</color> <color name="solid_saffron">#ffff6414</color> <color name="solid_blue">#ff0000ff</color> <color name="solid_green">#ff00ff00</color> <color name="solid_yellow">#ffffff00</color> <color name="saffron">#ffffa649</color> <color name="titlebackgroundcolor">#fffe8625</color> <color name="listitem_divide">#ffd4d3d3</color> <color name="gray">#ff666664</color> <color name="deep_gray">#ff555555</color> <color name="light_gray">#ff757575</color> <color name="btn_focused_color_yellow">#fffdfdfd</color> <color name="btn_pressed_color_light">#fffdfdfd</color> <color name="btn_default_color_light">#ffff5f11</color> <color name="rounded_container_border">#ffb7babb</color> <color name="base_start_color_default">#ffffffff</color> <color name="base_end_color_default">#ffffffff</color> <color name="base_start_color_pressed">#ffff7a13</color> <color name="base_center_color_pressed">#ffff8c2f</color> <color name="base_end_color_pressed">#ffffa254</color> <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(255,255,255)); 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);
