先看效果图：
Step1:定义StepBean
定义五个状态，分别为：为完成、正在进行、已完成、终点完成、终点未完成。
public class StepBean{ public static final int STEP_UNDO = -1;//未完成 public static final int STEP_CURRENT = 0;//正在进行 public static final int STEP_COMPLETED = 1;//已完成 public static final int STEP_LAST_COMPLETED = 2;//终点完成 public static final int STEP_LAST_UNCOMPLETED = 3;//终点未完成 private String name; private int state; public String getName(){ return name; } public void setName(String name){ this.name = name; } public int getState(){ return state; } public void setState(int state){ this.state = state; } public StepBean(){ } public StepBean(String name, int state){ this.name = name; this.state = state; } }
Step2:自定义HorizontalStepsViewIndicator

Step3:自定义HorizontalStepView
public class HorizontalStepView extends LinearLayout implements HorizontalStepsViewIndicator.OnDrawIndicatorListener{ private RelativeLayout mTextContainer; private HorizontalStepsViewIndicator mStepsViewIndicator; private List<StepBean> mStepBeanList; private int mComplectingPosition; private int mUnComplectedTextColor = ContextCompat.getColor(getContext(), R.color.uncompleted_text_color);//定义默认未完成文字的颜色; private int mComplectedTextColor = ContextCompat.getColor(getContext(), R.color.completed_color);//定义默认完成文字的颜色; private int mTextSize = 14;//default textSize private TextView mTextView; public HorizontalStepView(Context context){ this(context, null); } public HorizontalStepView(Context context, AttributeSet attrs){ this(context, attrs, 0); } public HorizontalStepView(Context context, AttributeSet attrs, int defStyleAttr){ super(context, attrs, defStyleAttr); init(); } private void init(){ View rootView = LayoutInflater.from(getContext()).inflate(R.layout.widget_horizontal_stepsview, this); mStepsViewIndicator = (HorizontalStepsViewIndicator) rootView.findViewById(R.id.steps_indicator); mStepsViewIndicator.setOnDrawListener(this); mTextContainer = (RelativeLayout) rootView.findViewById(R.id.rl_text_container); } /** * 设置显示的文字 * @param stepsBeanList * @return */ public HorizontalStepView setStepViewTexts(List<StepBean> stepsBeanList) { mStepBeanList = stepsBeanList; mStepsViewIndicator.setStepNum(mStepBeanList); return this; } /** * 设置未完成文字的颜色 * @param unComplectedTextColor * @return */ public HorizontalStepView setStepViewUnComplectedTextColor(int unComplectedTextColor) { mUnComplectedTextColor = unComplectedTextColor; return this; } /** * 设置完成文字的颜色 * @param complectedTextColor * @return */ public HorizontalStepView setStepViewComplectedTextColor(int complectedTextColor) { this.mComplectedTextColor = complectedTextColor; return this; } /** * 设置StepsViewIndicator未完成线的颜色 * @param unCompletedLineColor * @return */ public HorizontalStepView setStepsViewIndicatorUnCompletedLineColor(int unCompletedLineColor) { mStepsViewIndicator.setUnCompletedLineColor(unCompletedLineColor); return this; } /** * 设置StepsViewIndicator完成线的颜色 * @param completedLineColor * @return */ public HorizontalStepView setStepsViewIndicatorCompletedLineColor(int completedLineColor) { mStepsViewIndicator.setCompletedLineColor(completedLineColor); return this; } /** * 设置StepsViewIndicator默认图片 * @param defaultIcon */ public HorizontalStepView setStepsViewIndicatorDefaultIcon(Drawable defaultIcon) { mStepsViewIndicator.setDefaultIcon(defaultIcon); return this; } /** * 设置StepsViewIndicator已完成图片 * @param completeIcon */ public HorizontalStepView setStepsViewIndicatorCompleteIcon(Drawable completeIcon) { mStepsViewIndicator.setCompleteIcon(completeIcon); return this; } /** * 设置StepsViewIndicator正在进行中的图片 * @param attentionIcon */ public HorizontalStepView setStepsViewIndicatorAttentionIcon(Drawable attentionIcon) { mStepsViewIndicator.setAttentionIcon(attentionIcon); return this; } public HorizontalStepView setStepsViewIndicatorLastCompleteIcon(Drawable lastCompleteIcon) { mStepsViewIndicator.setLastCompleteIcon(lastCompleteIcon); return this; } public HorizontalStepView setStepsViewIndicatorLastUnCompleteIcon(Drawable lastUnCompleteIcon) { mStepsViewIndicator.setLastUnCompleteIcon(lastUnCompleteIcon); return this; } /** * set textSize * @param textSize * @return */ public HorizontalStepView setTextSize(int textSize) { if(textSize > 0) { mTextSize = textSize; } return this; } @Override public void ondrawIndicator() { if(mTextContainer != null) { mTextContainer.removeAllViews(); List<Float> complectedXPosition = mStepsViewIndicator.getCircleCenterPointPositionList(); if(mStepBeanList != null && complectedXPosition != null && complectedXPosition.size() > 0) { for(int i = 0; i < mStepBeanList.size(); i++) { mTextView = new TextView(getContext()); mTextView.setTextSize(TypedValue.COMPLEX_UNIT_SP, mTextSize); mTextView.setText(mStepBeanList.get(i).getName()); int spec = MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED); mTextView.measure(spec, spec); // getMeasuredWidth int measuredWidth = mTextView.getMeasuredWidth(); mTextView.setX(complectedXPosition.get(i) - measuredWidth / 2); mTextView.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT)); if(i <= mComplectingPosition) { mTextView.setTypeface(null); mTextView.setTextColor(mComplectedTextColor); } else{ mTextView.setTextColor(mUnComplectedTextColor); } mTextContainer.addView(mTextView); } } } } }
Step4:如何使用?
在布局文件xml中：
<cn.comnav.utrain.ui.widget.HorizontalStepView android:id="@+id/hsv_step_view" android:layout_width="match_parent" android:layout_height="80dp" android:layout_below="@+id/ll_role" android:layout_marginBottom="40dp" />
在Activity中的使用，部分代码截取：
private List<StepBean> stepsBeanList; private HorizontalStepView mHorizontalStepView; mHorizontalStepView=(HorizontalStepView)findViewById(R.id.hsv_step_view); stepsBeanList = new ArrayList<>(); StepBean stepBean0=null; StepBean stepBean1=null; StepBean stepBean2=null; StepBean stepBean3=null; switch (stepIndex){ case 1: stepBean0 = new StepBean("手机绑定",1); stepBean1 = new StepBean("实名认证",0); stepBean2 = new StepBean("学时充值",-1); stepBean3 = new StepBean("开始用车",3); break; case 2: stepBean0 = new StepBean("手机绑定",1); stepBean1 = new StepBean("实名认证",1); stepBean2 = new StepBean("学时充值",0); stepBean3 = new StepBean("开始用车",3); break; case 3: stepBean0 = new StepBean("手机绑定",1); stepBean1 = new StepBean("实名认证",1); stepBean2 = new StepBean("学时充值",1); stepBean3 = new StepBean("开始用车",2); break; } stepsBeanList.add(stepBean0); stepsBeanList.add(stepBean1); stepsBeanList.add(stepBean2); stepsBeanList.add(stepBean3); mHorizontalStepView.setStepViewTexts(stepsBeanList);
