篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了使用HorizontalListView仿车来了公交时刻表相关的知识，希望对你有一定的参考价值。
最近公司的项目中的一个模块做了一个和车来了app的公交时刻表相似的功能，里面使用了一个水平的ListView 来显示在不同车站上车辆的运行情况，公司采用网页做的，今天周六，我使用Listview来实现下，下面上图，给大家看下效果，最近也不知道咋的了，我写博客上传图片一直不能成功，我会尽快找到办法，成功上传图片。
开始吧，做这个我们会使用到水平的ListView，这个我直接上GitHub,在上面找了一个评价最好的，下载下来看了下，发现效果还行就直接用了。我们在水平的Listview中设置的item 就是每站的车辆情况和车站的信息，为了做成和车来了很相似，我给Item设置了3种样式，其实也可是直接使用一种，然后根据情况来决定其中一些View 的显示和不显示来完成。在下面我会贴出关键的代码，对其中的重要代码进行解释，文章的最后我会上传这个Demo的代码，是AS的。
activity_main 主页面布局文件：
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:widget="http://schemas.android.com/apk/res-auto"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:padding="5dp"
android:text="公交路线"
android:textSize="18sp" />
<com.meetme.android.horizontallistview.HorizontalListView
android:id="@+id/hlvSimpleList"
android:layout_width="match_parent"
android:layout_height="300dp" />
</LinearLayout>
</ScrollView>
MainActivity 的代码：
package com.example.dell.myhlistview;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import com.meetme.android.horizontallistview.HorizontalListView;
import java.util.ArrayList;
public class MainActivity extends AppCompatActivity
private HorizontalListView hlvSimpleList; // 水平的ListView
private ArrayList<String> arrayList;
private BusAdapter busAdapter; // 水平的Listview的adapter
protected void onCreate(Bundle savedInstanceState)
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
hlvSimpleList = (HorizontalListView)findViewById(R.id.hlvSimpleList);
// 在List中添加车站的名称信息
arrayList = new ArrayList<String>();
arrayList.add("三森美居广场");
arrayList.add("三森家具广场");
arrayList.add("雁塔交警大队");
arrayList.add("书刊批发市场");
arrayList.add("日杂市场");
arrayList.add("雁滩路西口");
arrayList.add("滩尖子");
arrayList.add("宁卧庄宾馆");
arrayList.add("南昌路十字");
arrayList.add("盘旋路西口");
busAdapter = new BusAdapter(this,arrayList);
hlvSimpleList.setAdapter(busAdapter);
适配器的代码，BusAdapter：
package com.example.dell.myhlistview;
import android.content.Context;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageView;
import android.widget.TextView;
import java.util.ArrayList;
