这是我的xml文件,我想在其中看到列表视图“水平”这是我试图在应用程序的资源屏幕上看到的布局

<!--this is the serving layout for the adapter by which i am trying to add items in the list view -->

<TextView

这是我用来将视图或项添加到列表视图的xml
适配器的Myresourcesadapter.class文件:
public class Myresourcesadapter extends ArrayAdapter<String> {
private final Activity context;
private final String[] itemName;
private final Integer[] imageResources;
// created constructor
public Myresourcesadapter(Activity context, String[] itemName, Integer[] imageResources) {
super(context, R.layout.list_single_row,itemName);
this.context = context;
this.itemName = itemName;
this.imageResources = imageResources;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
if(convertView != null){
} else {
LayoutInflater inflater = context.getLayoutInflater();
convertView = inflater.inflate(R.layout.list_single_row,null);
TextView textView_resource = (TextView) convertView.findViewById(R.id.text_view_resources);
ImageView imageView_resources = (ImageView) convertView.findViewById(R.id.imageview_resources);
String data = itemName[position];
textView_resource.setText(data);
imageView_resources.setImageResource(imageResources[position]);
}
return convertView;
}
}
ResourcesActivity.java:
public class ResourcesActivity extends AppCompatActivity {
private static String TAG = ResourcesActivity.class.getSimpleName();
ListView listView_resources;
Context context_resources;
ArrayList proglist;
Integer[] imageResources={
R.drawable.video,
R.drawable.manual,
R.drawable.faqs,
R.drawable.multimedia,
R.drawable.map
};
String [] itemName = {
"Video" , "Manual" , "faqs" , "Multimedia" , "maps"
};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.resources_activity);
Myresourcesadapter myresourcesadapter = new Myresourcesadapter(this,itemName,imageResources);
listView_resources = (ListView) findViewById(R.id.List_view_resources);
listView_resources.setAdapter(myresourcesadapter);
}
}
这些都是我的文件,我试图实现listview水平,但不能。我已经尝试了一切,请帮助。

考虑使用
RecyclerView
,它的功能更强大,并且支持本机水平滚动。您可以通过设置水平
LinearLayoutManager
来使用RecyclerView
,如下所示:oxcyiej72#
考虑使用回收器视图。这是解决这个问题的现代方法。这是我如何做一个水平回收器视图。
