HorizontalScrollView inside ListView

Question

I am trying to make a horizontal scroll view inside a ListView. I have a ListView working, but inputting data into horizontalscrollview (HSV) does not work for me. Please advise! (I have encoded the list, tested it and am now trying to add horizontalscrollview)

HSV will be for each list.

So, basically for my logic on how I approach this: I have my own listview adapter, I decided to put the HSV inside the adapter so that it goes through each listItem and puts the HSV in it.

My Xml looks like this:

<?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> 

Then I created a custom adapter to run all projects.

 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; } 

}

This last bit of code is where the adapter will go through the HSV, but something is not working, as I would like, please help!

Please follow the following link to HSV in ListView: http://www.dev-smart.com/archives/34

OR

 @Override public boolean onTouchEvent(MotionEvent event) { boolean handled = mGesture.onTouchEvent(event); return handled; } Then, add the following code which will decide to steal the event from the item children and give it to our onTouchEvent, or let it be handled by them. @Override public boolean onInterceptTouchEvent(MotionEvent ev) { switch( ev.getActionMasked() ){ case MotionEvent.ACTION_DOWN: mInitialX = ev.getX(); mInitialY = ev.getY(); return false; case MotionEvent.ACTION_MOVE: float deltaX = Math.abs(ev.getX() - mInitialX); float deltaY = Math.abs(ev.getY() - mInitialY); return ( deltaX > 5 || deltaY > 5 ); default: return super.onInterceptTouchEvent(ev); } } Finally, don't forget to declare the variables in your class: private float mInitialX; private float mInitialY;

This line does not work in your code, you create a new linearLayout file, but not from your user view:

 projectView = new LinearLayout(getContext()); 

So try the following:

 View projectView = convertView; // Inflate the view if (projectView == null) { String inflater = Context.LAYOUT_INFLATER_SERVICE; LayoutInflater vi; vi = (LayoutInflater) getContext().getSystemService(inflater); projectView = vi.inflate(resource, false); } 

And define your projectView as a view, not a LinearLayout.
