I have a listActivity which I use ArrayAdapter insider it. When user scrolls the scroll ball, one listitem would be focused. How can I know itemlist is highlighted?
It looks simple to me at first, however, it takes several days and still can't find answer.

I want to remove the listitem from listview in android.i don't know that how to do it.

View 1 Replies View RelatedI have a View that extends Activity. A ListView will display a number of listitems. When the user long clicks I would like to present them with a contextmenu allowing them to select edit, delete etc. and then identify the listitem that was selected as the item to perform the action on.
In onCreate I have:
listView.setAdapter(adapter);
listView.setOnItemClickListener(onListClick);
listView.setOnItemLongClickListener(onListLongClick);
registerForContextMenu(listView);
I have a method onCreateContextMenu
@Override
public void onCreateContextMenu(ContextMenu menu, View v,
ContextMenuInfo menuInfo) {
super.onCreateContextMenu(menu, v, menuInfo);
menu.setHeaderTitle("Context Menu");
menu.add(0, v.getId(), 0, "Edit");
menu.add(0, v.getId(), 0, "Delete");
and also onContextItemSelected
@Override
public boolean onContextItemSelected(MenuItem item) {
if (item.getTitle() == "Edit") {
// edit action
} else if (item.getTitle() == "Delete") {
// delete action
} else {
return false;
return true;
}I am not sure where to go from here to get the correct row/listitem.
I am showing a RSS feed in my application using Webview as ListItem and it works great except that it is very sluggish at times. Since I don't know the size of the content then I can't set the height of each Webview and therefore I have the following code (this is the code for a single ListItem)...
But the "wrap_content" causes the Webview to readjust size when scrolling. The scrollbar-indicator of the listview also has problems knowing the size of the complete list so it changes size when scrolling. All this causes a very "jerky" experience when scrolling.
Is there any better way of doing this?

View 1 Replies View RelatedI have this custom layout:
- LinearLayout
- FrameLayout
- ImageView
- TextView
This layout reacts to click events (using LinearLayout.setOnClickListener()) and is made focusable using android:focusable="true" in the layout XML file. This all works fine if you're using the touchscreen, but I'm thinking about users who don't use the touchscreen that much and prefer navigation keys or maybe even don't have a touchscreen. These users won't be able to see when that ViewGroup is focused (although it can be focused using the keyboard).
My question is: how can I make a change in that layout when it is focused (I need to change the android:background of the ImageView)? I suppose I could use LinearLayout.setOnFocusChangeListener(), but I'm thinking maybe there's a better way, using just XML files.
If I set my ImageView to be both clickable and focusable, it works, but I have no way to tell which image is focused. What's the best way to get it to draw an orange border around the view so the user knows it's currently in focus? I tried dropping it in a LinearLayout and setting that to be focusable and clickable instead, but didn't have any luck. Even when I put a margin on it, there's nothing to indicate that it was selected.
View 1 Replies View RelatedI created a small Tab-Layout. Now how can i specify the color of the TabWidget depending on its state (focused,pressed..) I built a new .xml, but i dont know how to set it to my Tabs:
<?xml version="1.0" encoding="UTF-8"?> <selector
android:id="@+id/tabSelector"
xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:state_focused="false"
android:state_selected="false"
android:state_pressed="true"
android:background="#32CD32"/> <br />
<item
android:state_focused="false"
android:state_selected="true"
android:state_pressed="false"/>
<item
android:state_focused="true"
android:state_selected="false"
android:state_pressed="false"/>
<item
android:state_focused="true"
android:state_selected="true"
android:state_pressed="false"/>
A good example of this is either on the Twitter launch screen (the screen with the large icons that is seen when the application is first launch) or even just look at the application tray when you focus an application icon.
Basically I need to highlight an ImageView where the highlight contours to the image within the ImageView and looks like it's a border to that image. I would also like to customize the highlight to have it be a certain color and for it to fade out.
My application opens in Activity A1. None of the views in A1 are focused at startup, until I use the arrow keys to navigate through the views. A button press in A1 launches activity A2. When A2 opens, the first Button in A2 is focused by default. I do not want this happen. What I want is when A2 opens, none of the buttons are focused until arrow keys are used to naviagte through them(just like it is in A1).
View 1 Replies View RelatedIf I have a layout with lots of EditText views in a LinearLayout and the user focuses the third one down and flips out the keyboard to start typing, the entire layout is destroyed and recreated through the activity lifecycle. When everything is done, however, the third EditText is given focus again and the user never knows that anything happened and types away.
I am creating a similar layout, but due to the nature of my data, I have to dynamically create the list of EditTexts, mixed with some other views. The default layout has one EditText at the top, a ScrollView with a LinearLayout child (which will be filled with EditTexts later), and some action buttons at the bottom. I fill the LinearLayout with all the EditText fields I need (based on extras passed via intent).
This part works quite well, but the way the activty handles Runtime Configuration changes is broken now (from a UI perspective). Now if the user focuses the third EditText (which was dynamically created via new EditText()) and flips out the keyboard, the layout is destroyed and recreated, but focus is always given to the permanent EditText at the top of the screen.
Is there something I need to do when adding my dynamic views to make sure they can keep focus through orientation changes? is there a way I can work around the issue and force focus to be given to the last view that had it before the change?
I'm porting an application from iPhone to Android. The iPhone app has artwork for some dozen or more buttons in their normal and pressed state. That translated over just fine to Android. However, we of course currently don't have any images for the "focused" state.
Besides the work involved in creating all these focused button images, we're not sure exactly what color to set the focus too. Selection color varies from phone to phone, etc. We'd have to come up with some neutral "white glow" of some sort I suppose. Then the idea struck -- could we programmatically render a focus images for the buttons based on the current selection color? Have folks been doing anything like this in the Android dev community? Can you point me to some examples. A net search didn't turn up anything too useful, though perhaps I searched on the wrong keywords.
I have a TextView inside a LinearLayout. The LinearLayout is able to receive focus, and I want the textColor of the TextView to change when it does. I thought using a ColorStateList would work, but it would seem that the TextView does not receive focus when the LinearLayout does. I know that, because I have tried this code...
And nothing gets logged. I don't want to use an OnFocusChangeListener on the LinearLayout to change the textColor of the TextView, I think this has to be done from XML. The reason for that is because in another activity I have an ExpandableListView with a custom adapter and custom views and Android changes the textColors of the TextViews (from light to dark) inside my custom views when items are focused.
I have a textview, I set it as clickable and focusable - how do I get it to highlight to orange (like a button) when the user focuses it with the trackwheel etc? code...
View 2 Replies View RelatedI have encountered a problem with focused text fields in a WebView not showing entered text values.As long as a WebView text field has focus it will not show text or even the blinking cursor.You can select and highlight the text or unfocus the field to see it, but when it gains focus it will not show the text as if the foreground color of the text is white.The simplest code to demonstrate this is below.With the setTheme using a Light background, try typing values into the Email text field to notice that the text is not visible when the field is focused.
View 4 Replies View RelatedI'm using ExpandableListView in my app and one of the complains is that when expanded it's hard to visually distinguish where the child item ends and next group item begins. So I would like to change background of the child list item to the different shade. Brutal attempts that I've made so far were based on directly changing background color and text of the elements inside the child view item but that leads to loss of hovers and highlights. So my question is - what is a good strategy to achieve the above? I tried styles and selectors but what really bums me out - that if I change one thing then I need to add selectors for all combinations of focus/enabled etc. when all I'm trying to do it to overwrite a single thing. Is there a way to inherit parent style and set just a background for non- focused, enabled child item?

View 1 Replies View RelatedI have an activity with an EditText on top and a ScrollView with a LinearLayout inside it. The LinearLayout is populated in the onCreate method with a set of dynamic views based on an object passed with the initiating Intent. This is typically a set of EditTexts. The result is a list of EditTexts each corresponding to a different piece of data (and the dataset being edited is quite variable, so the list needs to be created dynamically like this).
The problem is, when one of these views has focus, and the orientation changes (say the user flips out the keyboard to type), the focus snaps to the EditText at the very top of the Activity. This is certainly undesired behavior as the user didn't intend to type in the top EditText when he/she flipped out the keyboard.
How can I dynamically create my list of views like this and not have this undesirable focus changing behavior?

Is there something missing from this?

I'm writing an application which connects to a back office site. The backoffice site contains a whole slew of JavaScript functions, at least 100 times the average site. Unfortunately it does not load them, and causes much of the functionality to not work properly. So I am running a test. I put a page out on my server which loads the FireBugLite javascript text. Its a lot of javascript and perfect to test and see if the Android WebView will load it. The WebView loads nothing, but the browser loads the Firebug Icon. What on earth would make the difference, why can it run in the browser and not in my WebView? Any suggestions.
More background information, in order to get the stinking backoffice application available on a Droid (or any other platform except windows) I needed to trick the bakcoffice application to believe what's accessing the website is Internet Explorer. I do this by modifying the WebView User Agent.Also for this application I've slimmed my landing page, so I could give you the source to offer me aid. package ksc.myKMB;
