I have 2 ways of displaying ListView data. I have a class for each type of row. I do not create the rows in an xml layout. (Each row is derived from View and does custom drawing). When I switch from 1 type of row to another how do I get the ListView to layout properly with the correct row heights, and refresh? Is View.forceLayout() on the right track?

I'm having trouble changing the data held within a TextView inside of a listView. I can access the data and send a toast of the text, but the list isn't updated when I change it.
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setListAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, presidents));
ListView lv = getListView();
lv.setTextFilterEnabled(true);
ListAdapter list_adapter = lv.getAdapter();
TextView var_x = (TextView) list_adapter.getView(0,null,null);
ListView list = getListView();
int count = list.getChildCount();
Toast.makeText(getApplicationContext(),(var_x).getText(),Toast.LENGTH_SHORT).show();
var_x.setText("not a president");}
How can I change the text/styling of a row once I've already created it?

i want to implement listview with uses different xml layouts for rows depending on underlying item. A non optimal solution will be int getView method just to inflate every time a new view depending on the item from the adapter. Is there a better way to do this?
View 2 Replies View Relatedis it possible to let my ListView show 2 different rows? On the picture you can see at the top something like a "teaser", the other rows are normal ListView. The screenshot is from the iPod. With their framework it is possible to show 2 different row styles. I badly need this on Android... Otherwise I would use a tabel design. But adding rows dynamically would be such an overhead instead of using ListView SimpleAdapter addItem...

View 5 Replies View Relatedi am quite new to android and i was wondering how i could go about adding a listview with different images and text. What i am trying to achieve is a listview with four rows which have a different Icon? I don't know how to set that up using the xml layout provided. should i build this using different multiple linear layout or is there a better way to go about it?.. All the examples i have seen all seem to be using one particular Icon and no much detail of the xml layout.

View 1 Replies View RelatedI have a Cursor that returns rows I use with a SimpleCursorAdapter to populate a ListView. I would like to filter some of the rows so they don't get displayed in my ListView. I use the data from the rows elsewhere in my Activity so I don't want to change my SQL to filter them with a WHERE clause. What is the best way to keep a row from being displaying in my ListView? Ideally I would check a column in my row and then only add rows to the ListView that satisfy a condition.

v = vi.inflate(R.layout.listrow, null);

Order o = items.get(position);
if (o != null) {
TextView tt = (TextView) v.findViewById(R.id.toptext);

if(o.getOrderDrawable()!=null){
thumb.setImageDrawable(o.getOrderDrawable());
}
else{
tt.setText(o.getOrderTitle());

return v;}
The problem is when scrolling; sometimes the correct image shows, but sometimes when scrolling back/forward, the images shows randomly and that is not associated with the row. The images are downloaded from the web.
Is there a way for setting a number of maximum visible rows for a listview?
View 1 Replies View RelatedSo, basically I have a custom View that contains a ListView with a custom Adapter that has the ability to read in information from the network (dumbed down HTML) and display it on a row by row basis. All of this works, but I need the text that is read in to be parsed as HTML which contains links that can be tapped on and launched in browser. I managed to do this by:
text.setText(Html.fromHtml(textBuffer), TextView.BufferType.SPANNABLE);
text.setMovementMethod(LinkMovementMethod.getInstance());
Works great, any <a href=""></a> links in the text are displayed as links and can be tapped. This is a side effect of now making it so the rest of the rows in the ListView cannot be tapped (or tapped and held). Basically, all the rows are non-selectable now. Is there any way to achieve both of what I need?
The row of my listview has 3 texts. What I want to do is to align all the rows texts vertically. I tried that using the TableLayout view for the row, and I've set the width for the first and third cell's as a constant. I'm not very happy using constants because of the porting issues. Is it possible to align these texts without in another way? Here is the layout...

I want to create a listview with rows that have an image and two textviews. This must be a very common activity but I can't find a class/or source code that does this.
View 9 Replies View RelatedI have a ListView in my app that has a background image. All of the rows are a semi transparent white (#35FFFFFF). Whenever I scroll the list, the rows turn a light green that obscures the background image until I stop scrolling (usually--sort of unpredictable). Sometimes it flickers between the background image/color and the green. And yes, I have set the cache color hint to #00000000. Any advice about this would be appreciated.

How can I color code individual rows in a ListView exactly like it is done in the native MESSAGING app? I do NOT want to simply do alternating rows, but I want to copy the format used in the MESSAGING app, where message rows have a different background color based on the username of the message. FYI: I am currently extending SimpleAdapter and overriding getView(int position, View convertView, ViewGroup parent) . In this method I am trying to calculate setting the background color based on the position as compared to a list of 'positions to highlight' that I am maintaining each time I update the list, but so far this is only working the first time the list is updated. In class that overrides SimpleAdapter:
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = super.getView(position, convertView, parent);
if(highlightPositions.contains(new Integer(position))){
view.setBackgroundColor(highlightColor);
}
else{
view.setBackgroundColor(normalColor);
}
return view;}
Does anyone know if there is an app that will change your settings to allow for 5 rows of icons on your homescreen other than a home replacement app. I'm running LauncherPro, but my phone (Droid X) has been a lot more glitchy since I installed it.
View 1 Replies View RelatedI've been trawling the internet looking for an answer for several hours, but I can't seem to find anyone who has been able to solve this. I've got a listview which uses enter code herea custom adapter. A row looks like this. The list is filled by an array. Everything works great. Now, I want the ImageView and the ToggleButton to react to clicks, so I implement the OnClickListener in my adapter, put the items position in each view's tag, and then I set their onclicklistener to this. Works great, except now I can't use the onListItemClick for starting an activity for the item! OK, I say, I just make the relativelayout holding the text in the middle there use the same onclicklistener. Works great. Everything is clickable, and life is good.
EXCEPT! Now, when I scroll the list, I cannot "continue" the scroll by just flinging again. This causes the scrolling to stop, and I have to fling once more to get it going again. It seems the onclick-thingy causes the fling-motion to be interpreted as a tap or something (it does not trigger the logic within onClick).
I know that this is possible by just going to the phone list on my HTC Hero, which has exactly the kind of layout and behaviour I want from my app. This app even seems to have the onItemClickListener working. So how can I make sure the list keeps scrolling, and still be able to click the togglebutton, listitem and the imageview? I've been stuck on this all day, and it's giving me a headache
I have the following, very simple test program for using a ListView. I create a ListView and set it as the content view. I set a ListAdapter which supplies the rows. There are 30 rows, and each row consists of a LinearLayout ViewGroup. Into that ViewGroup, I place a TextView and a Button. When I run the program, I find that I cannot select rows of the list. I can, however, scroll the list and click the button. If I remove the button from the LinearLayout (so that it contains only the TextView), then I am able to select rows of the list. I would like to be able to have buttons on my individual row views, and still be able to select rows of the list. On another forum, someone said that this was possible, but I am at a loss as to how to accomplish it.,.........................
View 1 Replies View RelatedI have android application with ListView, where each row has own "refresh" button. Refreshing content is based on asynchronous http call, so until it completes (or timeout) I'd like to display some kind of graphical "busy" marker in each affected (clicked) row. What is best practice to do it? I see animated gifs - i.e. ones with rotating circle - does not animate on Android. So far I tried RotateAnimation on static image, it looks OK but it's not what people are accustomed to. Is there any better way to mark individual row in ListView as being updated?
