PieRotateView

PieRotateView:这是一个可旋转,自动回弹,可惯性旋转的饼状图,多属性控制,使用简单,具备一个自定义View应有的基本素质

  • 原理 :自定义坐标象限,Move事件中不断叠加划过的角度,重绘arcPath,判断滑动或者点击到某个区块使用Region。
  • 功能
    • 1、可跟随手势旋转、旋转完自动回弹到区块中心。
    • 2、惯性旋转+旋转完后回弹到区块中心。
    • 3、点击某个区块自动旋转至该区块中心。
    • 4、指针箭头指到某个区块内发送区块select事件。
    • 5、提供了刷新入口(设置属性刷新、Data改变刷新)
  • 基本素质
    • 1、旋转屏幕状态不丢失,转之前啥样,回来还是啥样(处理好onSaveInstanceState和onRestoreInstanceState)
    • 2、暴露事件冲突接口,允许外界操作父控件的事件及该view自己的事件(因为这只是个View,没办法直接处理所有的滑动冲突场景)
    • 3、内存抖动要小,防止内存溢出。

示例(真机流畅丝滑,压缩的GIF丢帧严重)

Demo演示了普通用法和涉及到SwipeRefreshLayout+AppBarLayout等类似的滑动冲突的用法(细节请看代码)。

  • 1、普通使用 :没啥可说的,只有Down的点在圆的范围内才可以响应事件,否则通知父控件拦截
  • 2、下拉刷新及其他滑动冲突
    • 1、Down的点在圆内,通过onPromiseParentTouchListener方法中使用SwipeRefreshLayout.setEnabled(promise)通知外界设置SwipeRefreshLayout不可以滑动。
    • 2、在SwipeRefreshLayout的OnRefreshListener中设置PierotateView的setEnableTouch(false)方法通知刷新期间,PierotateView不响应任何事件。
    • 3、同理,监听AppBarLayout的滚动高度来控制只有完全展开才允许SwipeRefreshLayout下拉刷新和PierotateView旋转,否则都禁止
常规使用 下拉刷新及其他滑动冲突

开始使用

基本API

Data实例类 PieRotateViewModel,以下为使用期间会接触到的属性,前三个属性用于构造PieRotateViewModel,别的属性都是为绘制准备的,不用关心,也不用去设置。

属性 类型 作用
name String 表示该扇形区块的名字
num float 表示该扇形区块的数字(决定它的百分比占比,总数为所有的PieRotateViewModel num叠加)
color int 表示该扇形区块的颜色
percent String 表示该扇形区块所占的百分比

PieRotateView

方法 参数 作用
setEnableTouch boolean 设置是否可以消费事件(默认为true)
setPieRotateViewModelList List 设置Data
setFling boolean 设置是否可以惯性滑动
setRecoverTime int 设置回弹动画的时长
setCircleColor int 设置中间遮罩圆的颜色
setTextColor int 设置中间Text文本的颜色
setArrawColor int 设置下方指针箭头的颜色
setOnSelectionListener PieRotateView.onSelectionListener 指针指向某个区块以及点击事件指向的区块事件回调
setOnPromiseParentTouchListener PieRotateView.onPromiseParentTouchListener 通知外界是否允许pierotateview之上的view拦截事件
notifyDataChanged void 通知pierotateview数据源发生了改变,重置相关初始属性,刷新View
notifySettingChanged void 通知pierotateview某些设置发生了改变,刷新View

使用

引入

Step 1. Add it in your root build.gradle at the end of repositories:

allprojects {
	repositories {
		...
		maven { url 'https://jitpack.io' }
	}
}

Step 2. Add the dependency

dependencies {
        implementation 'com.github.NoEndToLF:PieRotateView:1.0.3'
}

布局XML中添加

布局XML中添加,与系统View使用方式一样,如果宽高只确定其一,另一个取其相同值,且圆的圆心由padding后的View中心,圆的半径为宽高中的较小值和对应的padding决定

<com.wxy.pierotateview.view.PieRotateView
               android:layout_width="match_parent"
               android:padding="20dp"
               android:id="@+id/pie"
               android:layout_height="wrap_content"></com.wxy.pierotateview.view.PieRotateView>

代码中设置Data和View属性

Demo中的SwipRefreshAppbarActivity和NormalActivity中有详细使用代码

设置Data

        List<PieRotateViewModel> list = new ArrayList<>();
        list.add(new PieRotateViewModel("红扇", 20, getResources().getColor(R.color.colorAccent)));
        list.add(new PieRotateViewModel("绿扇", 10, getResources().getColor(R.color.colorPrimaryDark)));
        list.add(new PieRotateViewModel("蓝扇", 10, Color.BLUE));
        list.add(new PieRotateViewModel("黄扇", 60, Color.parseColor("#FF7F00")));
        list.add(new PieRotateViewModel("粉扇", 50, Color.parseColor("#EE7AE9")));
        pie.setPieRotateViewModelList(list);

刷新Data,可以重新使用setPieRotateViewModelList,或者重置list后调用pie.notifyDataChangeChanged(),刷新期间禁止PieRotateView消费事件。

swipe.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
            @Override
            public void onRefresh() {
                pie.setEnableTouch(false);

                new Handler().postDelayed(new Runnable() {
                    @Override
                    public void run() {
                        list.clear();
                        list.add(new PieRotateViewModel("红扇", 20, getResources().getColor(R.color.colorAccent)));
                        list.add(new PieRotateViewModel("绿扇", 10, getResources().getColor(R.color.colorPrimaryDark)));
                        pie.notifyDataChanged();
                        swipe.setRefreshing(false);
                        pie.setEnableTouch(true);
                    }
                },2000);
            }
        });	

添加区块选中回调;

pie.setOnSelectionListener(new PieRotateView.onSelectionListener() {
            @Override
            public void onSelect(int position, String percent) {
                tvName.setText(list.get(position).getName() + "数额:" + list.get(position).getNum() + " 占比:" + percent);
                tvName.setTextColor(list.get(position).getColor());
            }
        });

添加事件处理回调,即通知外界是否要拦截事件;

pie.setOnPromiseParentTouchListener(new PieRotateView.onPromiseParentTouchListener() {
            @Override
            public void onPromiseTouch(boolean promise) {
                swipe.setEnabled(promise);
            }
        });

修改pieratateview的其他属性,如果设置属性在setPieRotateViewModelList之前则不需要调用notifySettingChanged(),因为setPieRotateViewModelList会让View重绘,属性自然会生效,反之设置下方的属性后,需要再调用notifySettingChanged()通知View刷新,

方法 参数 作用
setFling boolean 设置是否可以惯性滑动
setRecoverTime int 设置回弹动画的时长
setCircleColor int 设置中间遮罩圆的颜色
setTextColor int 设置中间Text文本的颜色
setArrawColor int 设置下方指针箭头的颜色
