android 自定义 styleable 属性
1.定义
attr.xml中定义
<resources> <declare-styleable name="ViewFlow"> <attr name="sidebuffer" format="integer" /> </declare-styleable> <declare-styleable name="CircleFlowIndicator"> <attr name="activeColor" format="color" /> <attr name="inactiveColor" format="color" /> <attr name="radius" format="dimension" /> <attr name="spacing" format="dimension" /> <attr name="centered" format="boolean" /> <attr name="fadeOut" format="integer" /> <attr name="inactiveType"> <flag name="stroke" value="0" /> <flag name="fill" value="1" /> </attr> <attr name="activeType"> <flag name="stroke" value="0" /> <flag name="fill" value="1" /> </attr> <attr name="snap" format="boolean" /> </declare-styleable> <declare-styleable name="TitleFlowIndicator"> <attr name="titlePadding" format="dimension" /> <!-- Left/right padding of not active view titles. --> <attr name="clipPadding" format="dimension" /> <attr name="selectedColor" format="color" /> <attr name="selectedBold" format="boolean" /> <attr name="selectedSize" format="dimension" /> <attr name="textColor" format="color" /> <attr name="textSize" format="dimension" /> <attr name="footerLineHeight" format="dimension" /> <attr name="footerColor" format="color" /> <attr name="footerTriangleHeight" format="dimension" /> <attr name="customTypeface" format="string" /> </declare-styleable> </resources>
相关字段
resources -> declare-styleable ->attr( name ,format (color,dimension,boolean,string,integer,)) or -> flag(name,value)
2.layout中的使用
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res/org.taptwo.android.widget.viewflow.example" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <org.taptwo.android.widget.CircleFlowIndicator android:padding="10dip" android:layout_height="wrap_content" android:layout_width="wrap_content" android:id="@+id/viewflowindic" android:layout_gravity="center_horizontal" app:inactiveType="fill" app:fadeOut="1000" /> <org.taptwo.android.widget.ViewFlow android:id="@+id/viewflow" android:layout_width="fill_parent" android:layout_height="fill_parent" app:sidebuffer="3"></org.taptwo.android.widget.ViewFlow> </FrameLayout>
1.xmlns:app="http://schemas.android.com/apk/res/org.taptwo.android.widget.viewflow.example"
app为自定义标签前缀 路径为 http://schemas.android.com/apk/res + 资源路径(包名)
2.app:inactiveType="fill" app:fadeOut="1000" app:textColor="#FFFFFFFF" app:footerTriangleHeight="10dp" app:customTypeface="fonts/Antic.ttf"
如上定义 inactivieType是自定义类型 fadeOut是integer类型 textColor是color类型 footerTriangleHeight是dimension类型 customTypeface是string类型
3.view中读取
TypedArray a = context.obtainStyledAttributes(attrs,
R.styleable.CircleFlowIndicator);
// Gets the active circle type, defaulting to "fill"
int activeType = a.getInt(R.styleable.CircleFlowIndicator_activeType,
STYLE_FILL);
int activeDefaultColor = 0xFFFFFFFF;
// Get a custom active color if there is one
int activeColor = a
.getColor(R.styleable.CircleFlowIndicator_activeColor,
activeDefaultColor);
如上 1.obtion TypedArray 2.getInt getColor 等
