ListView Not Scrollable

meirrotfleisch · May 2020

I have a layout with a listview and below it a "toolbar" I want the list to be scrollable i Used verticaloptions="fillandExpand" but doesn't help

The following is my layout

<?xml version="1.0" encoding="utf-8"?>

    <Toolbar
        android:id="@+id/toolbar_bottom"
        android:minHeight="?android:attr/actionBarSize"
        android:background="?android:attr/colorAccent"
        android:theme="@android:style/ThemeOverlay.Material.Dark.ActionBar"
        android:popupTheme="@android:style/ThemeOverlay.Material.Light"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
     android:layout_alignParentBottom="true"/>

Looking foward to your kind help

1.In activity EventListActivity, the SimpleCursorAdapter use layout EventListItem as the item layout.

var adapter = new SimpleCursorAdapter(this, Resource.Layout.EventListItem,
             cursor, sourceColumns, targetResources)
        {
            ViewBinder = new ViewBinder()
        };

2.In activity EventListItemActivity, you use layout EventListItem as the page layout.

  protected override void OnCreate(Bundle savedInstanceState)
        {
            base.OnCreate(savedInstanceState);

            SetContentView(Resource.Layout.EventListItem);

          // other code
   }

So, you used the same layout EventListItem.

@meirrotfleisch Can you post the complete content including the ListView implementation? The current XML only shows the Toolbar.

@meirrotfleisch Thanks for sharing the ListView implementation. I also need to see the XML file. Since the data is getting displayed for you except the scroll is not working as you mentioned initially, need to see the XML.

Hi @meirrotfleisch, from the code you posted , I found that you didn't post the full code.
What's the code of MyUtils and MyReceiver?

If it is convenient for you, could you please post a basic demo so that we can test on our side?

meirrotfleisch · May 2020

Thanks for your response. I dont see why myutils and myreceiver should effect the listview. They deal with calendar 📅 events and setting alarms. How ever when I get to the office 🏢 I'll send the full project

Hi

I'm pretty sure i'v narrowed the problem down to the combination of Bottom_toolbar and listview.
Ill try to create a demo of the situation later on.

in the mean time Any suggestions?

Regards

meirrotfleisch · May 2020

HI

My app is based on this original demo. I added the "bottom_toolbar" to the EventList.axml and the EventListActivity.cs

Here the scroll will work but if the list is long the toolbar doesn't show.

Rather confusing.. Why its reacting differently

Thanks .. Looking forward to your helpful responses

You just need to add the following property for your listview:

android:layout_weight="1"

@jezh
Thanks..

This seems to have helped a bit . but I still seem to be getting a "toolbar" between each item of the listview

See attached screen shot (from the real app not the demo)

I have modified some codes and added the runtime permission in your code , and I also tesed on my device, it works properly.

I have uploaded the demo in the attachment, you can check it here.

meirrotfleisch · May 2020

@jezh : Thanks again for your time.

When I try to install your demo on a Samsung Galaxy s5 after the request for calendar permissions i get a message saying "screen Overlay detected" and that i need to turn off screen overlay from Settings >apps. Tried to but still it wont load

When I install on my other device Samsung Galaxy S5 it runs correctly.

However on my full app (added many features) I still haven't been able to get rid of the "blank toolbar" between each Listed Event.

I'm attaching my full code here

However on my full app (added many features) I still haven't been able to get rid of the "blank toolbar" between each Listed Event.

In the EventListItem.axml, you have defined a Toolbar in the layout.You can just remove the Toolbar.

  <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
    <TextView
        android:id="@+id/eventTitle"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textSize="16dip" />
    <TextView
        android:id="@+id/eventStartDate"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textSize="12dip" />
    <TextView
        android:id="@+id/eventId"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textSize="12dip" />
    <TextView
        android:id="@+id/EventDescription"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textSize="12dip" />
    <Toolbar
        android:id="@+id/toolbar_bottom2"
        android:minHeight="?android:attr/actionBarSize"
        android:background="?android:attr/colorAccent"
        android:theme="@android:style/ThemeOverlay.Material.Dark.ActionBar"
        android:popupTheme="@android:style/ThemeOverlay.Material.Light"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom"
    />
</LinearLayout >

After I removed the toolbar, the result is:

@jezh That solves it for the Alarms List but then when I want to go to the Details (click item in EventList) the EventListItem no longer has its toolbar ...

You can create a new layout for this activity(the Details (click item in EventList)).

Or just hide the toolbar in EventListActivity and display it in EventListItemActivity .

android:visibility="gone"

and

android:visibility="visible"

@jezh

I guess my challenge here is how/where are the two layouts being "combined"?

1.In activity EventListActivity, the SimpleCursorAdapter use layout EventListItem as the item layout.

var adapter = new SimpleCursorAdapter(this, Resource.Layout.EventListItem,
             cursor, sourceColumns, targetResources)
        {
            ViewBinder = new ViewBinder()
        };

2.In activity EventListItemActivity, you use layout EventListItem as the page layout.

  protected override void OnCreate(Bundle savedInstanceState)
        {
            base.OnCreate(savedInstanceState);

            SetContentView(Resource.Layout.EventListItem);

          // other code
   }

So, you used the same layout EventListItem.
