一、实际项目效果图

二、效果分析
效果分析.png
  1. 条目有三种样式:第一条、中间部分、最后一条
  2. 一个条目分成三个部分,二条线加一个图标
  3. 图标大小有二种样式
  4. 二条线均可以设置显示或者隐藏
三、自定义属性
<declare-styleable name="StepProgressLayout">
        <!--第一个条目的图片、大小-->
        <attr name="step_first_image" format="reference" />
        <attr name="step_first_image_size" format="dimension" />
        <!--第一条Top线的高度-->
        <attr name="step_first_line_height" format="dimension" />
        <!--正常条目的图片、大小-->
        <attr name="step_normal_image" format="reference" />
        <attr name="step_normal_image_size" format="dimension" />
        <!--正常条目Top线的高度-->
        <attr name="step_normal_line_height" format="dimension" />
        <!--线的大小、线的颜色-->
        <attr name="step_line_size" format="dimension" />
        <attr name="step_line_color" format="color|reference" />
       <!--条目样式-->
        <attr name="step_style" format="enum">
            <enum name="first" value="0" />
            <enum name="normal" value="1" />
            <enum name="end" value="2" />
        </attr>
    </declare-styleable>
四、自定义(R.layout.layout_view_step)布局样式
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:layout_constraintLeft_toLeftOf="parent"
    app:layout_constraintTop_toTopOf="parent">

    <View
        android:id="@+id/step_top_line"
        android:layout_width="1px"
        android:layout_height="22dp"
        android:background="#e6e6e6"
        app:layout_constraintBottom_toTopOf="@id/step_icon"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

    <ImageView
        android:id="@+id/step_icon"
        android:layout_width="20dp"
        android:layout_height="20dp"
        android:src="@drawable/ic_supplier_on"
        app:layout_constraintBottom_toTopOf="@id/step_bottom_line"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toBottomOf="@id/step_top_line" />

    <View
        android:id="@+id/step_bottom_line"
        android:layout_width="1px"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:background="#e6e6e6"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toBottomOf="@id/step_icon" />
</androidx.constraintlayout.widget.ConstraintLayout>
五、自定义StepProgressLayout布局
package cn.carhouse.yctone.view;

        }
    }


    /**

    private int dip2px(int dip) {
        return (int) (TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, dip, getResources().getDisplayMetrics()) + 0.5);
    }
}

提供了一些常用方法,每个公司的UI布局不一样,自己稍作调整就好。

六、列表条目(R.layout.supplier_item_express_track_item)布局技巧
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <!--换成你的View的位置-->
    <your view packet .StepProgressLayout
        android:id="@+id/step_view"
        android:layout_width="50dp"
        android:layout_height="0dp"
        app:layout_constraintBottom_toTopOf="@id/v_item_bottom_line"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        app:step_first_image="@drawable/ic_supplier_express_first"
        app:step_normal_image="@drawable/ic_supplier_express_normal"
        app:step_style="normal" />

    <TextView
        android:id="@+id/tv_name"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_marginTop="17dp"
        android:layout_marginRight="24dp"
        android:lineSpacingMultiplier="1.2"
        android:text="[深圳市] 快件已签收,感谢您!,期[深圳市] 快件已签收快件已签收快件已签收快件已签收快件已签收"
        android:textColor="@color/c_aa"
        android:textSize="14dp"
        app:layout_constraintLeft_toRightOf="@id/step_view"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="@id/step_view" />

    <TextView
        android:id="@+id/tv_time"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_marginTop="4dp"
        android:layout_marginRight="24dp"
        android:lineSpacingMultiplier="1.2"
        android:text="2016-07-12  12 : 30"
        android:textColor="@color/c_aa"
        android:textSize="14dp"
        app:layout_constraintLeft_toLeftOf="@id/tv_name"
        app:layout_constraintLeft_toRightOf="@id/step_view"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toBottomOf="@id/tv_name" />

    <View
        android:id="@+id/v_item_bottom_line"
        android:layout_width="0dp"
        android:layout_height="2px"
        android:layout_marginTop="14dp"
        android:background="@color/line_bg"
        app:layout_constraintLeft_toLeftOf="@id/tv_name"
        app:layout_constraintLeft_toRightOf="@id/step_view"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toBottomOf="@id/tv_time" />
</androidx.constraintlayout.widget.ConstraintLayout>

用底部的线来约束限制左边自己定义View的高度

七、列表Adapter测试代码
mRecyclerView.setAdapter(new XQuickAdapter<String>(getAppActivity(), items, R.layout.supplier_item_express_track_item) {
            @Override
            public void convert(XQuickViewHolder holder, String item, int position) {
                StepProgressLayout step = holder.getView(R.id.step_view);
                TextView tvName = holder.getView(R.id.tv_name);
                TextView tvTime = holder.getView(R.id.tv_time);
                // 第一个位置
                if (position == 0) {
                    step.changeFirstStyle();
                    holder.setBold(tvName, true);
                    holder.setBold(tvTime, true);
                    tvName.setTextColor(Color.parseColor("#FFDD2828"));
                    tvTime.setTextColor(Color.parseColor("#FFDD2828"));
                } else {
                    // 最后一个位置
                    if (position == getCount() - 1) {
                        step.changeEndStyle();
                    } else {
                        step.changeNormalStyle();
                    }
                    holder.setBold(tvName, false);
                    holder.setBold(tvTime, false);
                    tvName.setTextColor(Color.parseColor("#FFAAAAAA"));
                    tvTime.setTextColor(Color.parseColor("#FFAAAAAA"));
                }
            }
        });
  1. 看convert方法里面的逻辑就好,实际开发用自己的Adapter
