Android-View-生命周期

onFinishInflate            View布局解析完成（Activity.onCreate执行时调用）
onAttachedToWindow         View添加到Window中
onWindowVisibilityChanged  Window可见性
onVisibilityChanged        View可见性
onMeasure                  测量View尺寸（Activity.onResume执行后才开始View绘制）
onSizeChanged              View大小改变
onLayout                   布局View位置
onDraw                     绘制View内容
onWindowFocusChanged       Window焦点
onWindowVisibilityChanged  Window可见性
onVisibilityChanged        View可见性
onDetachedFromWindow       Window中移除View
