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。

复制代码
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;
}

}

Step4:如何使用?

在布局文件xml中:

复制代码
<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"
/>
复制代码
在Activity中的使用,部分代码截取:
