我正在尝试在ListView中创建一个水平滚动视图。我已经让ListView工作了,但是将数据放入HorizontalScrollView(HSV)对我来说并不起作用。请给予建议!(我编写了ListView,进行了测试,现在正在尝试添加HorizontalScrollView)
HSV将用于每个列表项。
因此,基本上我的逻辑是这样的:我有我的ListView适配器,我决定将HSV放在适配器内部,以便它循环遍历每个listItem,并将HSV放置在其中。
我的Xml如下所示:

我的Xml如下所示:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:baselineAligned="false"
android:layout_width="fill_parent" android:layout_height="fill_parent">
<LinearLayout
android:orientation="vertical"
android:layout_width="0dip" android:layout_weight="1"
android:layout_height="fill_parent">
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="@+id/txtProjectName" />
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="@+id/txtProjectDescription" />
<HorizontalScrollView
android:layout_width="wrap_content"
android:layout_height="match_parent" >
<LinearLayout
android:id="@+id/projectTasks"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal">
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="@+id/txtProjectTasks" />
</LinearLayout>
</HorizontalScrollView>
</LinearLayout>
</LinearLayout>
然后我创建了一个自定义适配器来遍历所有的项目。
public class ProjectListAdapter extends ArrayAdapter<Projects> {
int resource;
String response;
Context context;
ArrayList<Tasks> taskArray = null;
// Initialize adapter
public ProjectListAdapter(Context context, int resource,
List<Projects> items) {
super(context, resource, items);
this.resource = resource;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
LinearLayout projectView;
// Get the current project object
Projects project = getItem(position);
//
// Inflate the view
if (convertView == null) {
projectView = new LinearLayout(getContext());
String inflater = Context.LAYOUT_INFLATER_SERVICE;
LayoutInflater vi;
vi = (LayoutInflater) getContext().getSystemService(inflater);
vi.inflate(resource, projectView, true);
} else {
projectView = (LinearLayout) convertView;
}
TextView PROJECT_NAME = (TextView) projectView
.findViewById(R.id.txtProjectName);
TextView PROJECT_DESCRIPTION = (TextView) projectView
.findViewById(R.id.txtProjectDescription);
PROJECT_NAME.setText(project.getNAME());
PROJECT_DESCRIPTION.setText(project.getDESCRIPTION());
taskArray = new ArrayList<Tasks>();
taskArray = (ArrayList<Tasks>) project.getTasks();
for (Tasks tasks : taskArray) {
HorizontalScrollView TASKS = (HorizontalScrollView) projectView
.findViewById(R.id.projectTasks);
LinearLayout taskLayout = (LinearLayout) projectView
.findViewById(R.id.projectTasks);
TextView taskTxt = (TextView) projectView
.findViewById(R.id.txtProjectTasks);
taskTxt.setText(tasks.getTASK_ID());
taskLayout.addView(taskTxt);
}
return projectView;
}
最后一段代码是适配器将循环遍历以制作HSV,但某些地方不像我想的那样工作,请务必帮助!
