1.定義屬性attrs.xml
<!-- MyToolBarView -->
<declare-styleable name="MyToolBarView">
<!-- 是否使用沉浸式 默認false-->
<attr name="useSink" format="boolean" />
<!-- 是否顯示返回鍵 默認true -->
<attr name="showBackIcon" format="boolean" />
<!-- 是否顯示標題 默認true -->
<attr name="showTitleView" format="boolean" />
<!-- 是否顯示功能1圖標 默認false -->
<attr name="showFunIconOne" format="boolean" />
<!-- 是否顯示功能2圖標 默認false -->
<attr name="showFunIconTwo" format="boolean" />
<!-- 是否顯示功能1文字 默認false -->
<attr name="showFunTextOne" format="boolean" />
<!-- 是否顯示功能2文字 默認false -->
<attr name="showFunTextTwo" format="boolean" />
<!-- 設置標題內容 -->
<attr name="title" format="string" />
<!-- 設置功能1文字內容 -->
<attr name="funOneText" format="string" />
<!-- 設置功能2文字內容 -->
<attr name="funTwoText" format="string" />
<!-- 設置返回Icon -->
<attr name="backIcon" format="reference" />
<!-- 設置功能1Icon -->
<attr name="funOneIcon" format="reference" />
<!-- 設置功能2Icon -->
<attr name="funTwoIcon" format="reference" />
</declare-styleable>

3.測量ActionBar高度方法

4.測量狀態欄高度的方法
try {
int resourceId = getResources().getIdentifier("status_bar_height", "dimen", "android");
if (resourceId > 0) {
statusBarHeight = getResources().getDimensionPixelSize(resourceId);
}
} catch (Exception e) {
e.printStackTrace();
