【移動應(yīng)用開發(fā)技術(shù)】怎么在Kotlin中實現(xiàn)一個StepView方法

本篇文章為大家展示了怎么在Kotlin中實現(xiàn)一個StepView方法，內(nèi)容簡明扼要并且容易理解，絕對能使你眼前一亮，通過這篇文章的詳細介紹希望你能有所收獲。TimeLineStepView支持時間軸和StepView，三種布局，支持水平布局，垂直布局和自定義布局

添加依賴implementation

'com.joketng:TimeLineStepView:1.0.1'使用方法在布局文件中添加TimeLineStepView<com.joketng.timelinestepview.view.TimeLineStepView

android:id="@+id/rvVertical"

android:layout_width="match_parent"

android:layout_height="wrap_content"

app:lineWidth="3dp"

app:markSize="10dp"

android:paddingStart="20dp"

app:markStart="@drawable/shape_circle_orange"

app:layoutType="right"

/>在代碼中調(diào)用//OrientationShowType對應(yīng)三種布局方式

//OrientationShowType.TIMELINE(時間軸方式)

//OrientationShowType.CENTER_VERTICAL(垂直方式)

//OrientationShowType.CENTER_HORIZONTAL(水平方式，支持左右滑動)

rvVertical.initData(listContent,

OrientationShowType.CENTER_VERTICAL,

object

:

TimeLineStepView.OnInitDataCallBack{

override

fun

onBindDataViewHolder(holder:

TimeLineStepAdapter.CustomViewHolder,

position:

Int)

{

}

override

fun

createCustomView(leftLayout:

ViewGroup,

rightLayout:

ViewGroup,

holder:

TimeLineStepAdapter.CustomViewHolder)

{

//LayoutInflater.from(context).inflate(R.layout.item_add_left_view,

leftLayout,

true)

//LayoutInflater.from(context).inflate(R.layout.item_add_right_view,

rightLayout,

true)

}

})

.setLayoutType(type)//設(shè)置布局顯示的樣式左邊：LayoutType.LEFT,右邊：LayoutType.RIGHT,左右：LayoutType.ALL

//設(shè)置stepview進度激活的mark圖標(biāo)

.setMarkActive(ContextCompat.getDrawable(context,R.drawable.shape_dot_orange)!!)

//設(shè)置stepview進度沒激活的mark圖標(biāo)

.setMarkInActive(ContextCompat.getDrawable(context,R.drawable.shape_dot_gray)!!)

//設(shè)置stepview當(dāng)前進度點的mark圖標(biāo)

.setMarkCurrent(ContextCompat.getDrawable(context,R.drawable.shape_current)!!)

//設(shè)置stepview第一個mark的圖標(biāo)

.setMarkStart(ContextCompat.getDrawable(context,R.drawable.shape_circle_orange)!!)

//設(shè)置stepview最后一個mark的圖標(biāo)

.setMarkEnd(ContextCompat.getDrawable(context,R.drawable.shape_circle_orange)!!)

//設(shè)置stepview線的寬度

.setLineWidth(context.dipc(2))

//設(shè)置stepview進度激活時線的顏色

.setLineActiveColor(ContextCompat.getColor(context,R.color.c_main_orange))

//設(shè)置stepview進度沒有激活時線的顏色

.setLineInActiveColor(ContextCompat.getColor(context,R.color.c_main_gray))

//設(shè)置是否需要自定義布局(此時將createCustomView中的注釋打開將自定義布局傳入)

.setIsCustom(true)listContent的取值為mutableListOf()，當(dāng)存在自定義布局的時候，listContent中添加的實體需要繼承BaseBean這個實體，如果不需要自定義布局，可以直接添加實體BaseBeanlistContent.add(BaseBean(leftTitle

=

"11-11",

leftTime

=

"08:30",

rightTitle

=

"訂單提交成功",

rightTime

=

"訂單提交成功描述",

timeLineState

=

TimeLineState.ACTIVE))

listContent.add(BaseBean(leftTitle

=

"11-11",

leftTime

=

"08:31",

rightTitle

=

"訂單付款成功",

rightTime

=

"訂單付款成功描述",

timeLineState

=

TimeLineState.ACTIVE))

listContent.add(BaseBean(leftTitle

=

"11-11",

leftTime

=

"10:00",

rightTitle

=

"倉庫已經(jīng)接單",

rightTime

=

"倉庫已經(jīng)接單描述",

timeLineState

=

TimeLineState.ACTIVE))

listContent.add(BaseBean(leftTitle

=

"11-11",

leftTime

=

"10:30",

rightTitle

=

"倉庫處理中",

rightTime

=

"倉庫處理中描述",

timeLineState

listContent.add(BaseBean(leftTitle

"11-11",

leftTime

=

"11:00",

rightTitle

=

"已出庫",

rightTime

=

"已出庫描述",

timeLineState

TimeLineState.ACTIVE))

listContent.add(BaseBean(leftTitle

=

"11-11",

leftTime

=

"11:30",

rightTitle

=

"已發(fā)貨",

rightTime

=

"已發(fā)貨描述",

timeLineState

TimeLineState.CURRENT))

listContent.add(BaseBean(leftTitle

leftTime

"16:00",

rightTitle

"已攬件",

rightTime

TimeLineState.INACTIVE))

listContent.add(BaseBean(leftTitle

leftTime

=

"16:30",

rightTitle

=

"運輸中",

rightTime

=

"運輸中描述",

timeLineState

=

TimeLineState.INACTIVE))BaseBean的五個參數(shù)前四個為控件的文本,前四個參數(shù)不傳的話該控件就不會顯示,最后一個TimeLineState對應(yīng)進度的三種狀態(tài)TimeLineState.ACTIVE，TimeLineState.INACTIVE，TimeLineState.CURRENT，根據(jù)狀態(tài)在onBindDataViewHolder方法中設(shè)置markdrawable，linecolor等,在設(shè)置markSize的時候，如果大小超過30dp,需要在createCustomView方法或者onBindDataViewHolder方法中調(diào)用holder.llLine.layoutParams.width設(shè)置為大于等于markSize的大小或者設(shè)置為WrapContent，如下holder.llLine.layoutParams.width

=

context.dip(35)

holder.llLine.layoutParams.width

=

LinearLayout.LayoutParams.WRAP_CONTENT對于布局的顯示位置有要求的話可以在createCustomView方法中通過layoutParams來控制val

rightLayoutParams

=

rightLayout.layoutParams

as

LinearLayout.LayoutParams

rightLayoutParams.rightMargin

=

context.dip(30)如果不喜歡在代碼中設(shè)置控件屬性的話可以選擇布局文件中增加屬性<com.joketng.timelinestepview.view.TimeLineStepView

android:id="@+id/rvVertical"

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:paddingStart="20dp"

app:markSize="10dp"

app:markStart="@drawable/shape_circle_orange"

app:markEnd="@drawable/shape_circle_orange"

app:markActive="@drawable/shape_dot_orange"

app:markInActive="@drawable/shape_dot_gray"

app:markCurrent="@drawable/shape_circle_orange"

app:lineWidth="3dp"

app:lineActiveColor="@color/c_main_orange"

app:lineInActiveColor="@color/c_main_gray"

app:isCustom="false"

app:layoutType="right"

/>如果需要可以在onBindDataViewHolder方法中通過holder獲取控件改變控件的樣式，如果想要添加自定義的UI，可以在createCustomView方法中添加自己定義的布局文件，此時調(diào)用setIsCustom(true)即可rvVertical.initData(listContent,

OrientationShowType.CENTER_VERTICAL,

onBindDataViewHolder(holder:
