Android :: Click In List View Item Changes Status Of Elements Inside Item?

Apr 9, 2010

I don't know exactly how to explain this problem, but I'll try. I have a ListView with several items. Each item has inside a TextView and two ImageView. I want the ImageView change when I click on them, and I want to open a context menu when I press for a long time into the ListView item.For the ImageView, everything works properly. For the whole item, I can show the context menu after a long press, but my problem is that the ImageView changes as well when I am pressing the TextView, for example.I hope you understand my problem. I think that all the children of a view are affected by an event in the parent, but I am not sure.

Android :: Graphically Represent Multiple List Selections / Dynamically Change List Item View

Apr 23, 2010

I'm trying to create a multiple selection list where the selection is represented graphically rather than with checkboxes.My list has checkboxes, but I want them to serve a different purpose. I'm using a cursor to hold my data and created a custom view binder for the SimpleCursorAdapter. I did this for the checkboxes and general flexibility.So far I haven't even been able to show one line as being selected. I've enabled multiple selection on the list and denied the children of the list item focusability. I've tried manually changing background color with the position fed in through the list item click listener. But the wrong items get changed and they don't even change to the right color. I've enabled touch focusability with no improvement either.Ideally, I'd like the trackball highlight focus bar to appear in multiple places. But I don't think this is possible unless you use the drawable directly. But I don't know how to find or apply it. My next idea was to have a slim view bar that changes color. But I had the same problem with the wrong item being selected so I never finished trying to guess the index position to see if this would work. My most recent idea is to completely swap out the view for another one if it's selected. But I have no idea how to do this either. I'm thinking of using an array list to store the _id s of the items that need a different view to get around the wierd selection problem. I'm also thinking of passing in the ID field as my from and the selection view as the to for my adapter. Then I'd intercept it with my binder and change the view accordingly. But once again, I'm not sure how to do this successfuly.

Android :: List Item View With Text And Image

Dec 10, 2009

I'm developing an application which has an listview. I'm currently creating the list item view dynamically from code (linearlayout, which includes 2 textviews and 1 imageview), but i'd like to use an XML resource for this. I read it is resource intensive when getting this view using findViewById within a loop. I thought of using a custom adapter for this, but am not sure on how to include lazy loading of the image then.

Android :: Best Way To Create A Custom View For Every List Item?

Nov 4, 2010

As I am reviewing and prototyping my android project, I noticed that there is a view that has a list of items that are very customized. I have figured out most of my tools that I plan to use but I need some advice.

I have a list of items which can contain photos, some text to the right, an image to the bottom and more text below that. Very confusing I know. Each of these might be present for an item. The only thing that will always be there is the title.

So my question - what is the best way to create each custom list item view? I am thinking I have to use this getView to create each view. But when creating each view, is it best to 1) create a view dynamically and adding an image, for example, if it exists, or 2) create an xml file with all possible elements and hide them depending on the item?

Android : How To Add OnClick Handler To View In List Item

Aug 12, 2010

I have a ListActivity where the list items are defined in another XML layout. The list item layout contains an ImageView, a CheckBox, a TextView and such.

What I want is to set an onClick listener to the CheckBox in each list item. That is easy enough. The trouble is I need that onClick handler to know which position in the list it is.

I'm attaching the listener to the CheckBox in getView after that convertView has been inflated. The getView method has a position parameter, but I cannot reference it in the onClick handler for my CheckBox. I understand why, but I don't know how to get around it. How do I accomplish this?

Android :: Display Images On Demand Inside A Listview / Find Out List Item Is On Screen?

Oct 31, 2010

I am building a android aplication which will be consuming a json file from the internet. This json file contains a list of news from a particular website. Each json object contains information such like title, summary, descripition and web links for the news thumbnail and the original image.

I will be displaying in a listview three information: the news thumbnail, the title and the summary. Here resides my problem. I dont want to load all thumbnails from the internet if they wont be displayed. What I am trying to say is that why download a thumbnail from the 30th news if the user wont scroll down the image. So, i will, initially only download the thumnails from those news that are being displayed in the screen and when the user scrolls down to see more news, as soon as the list item appers to the screen i want to download the image and then display.

Is there a way to achieve this? Is it possible to find out if the list item is on the screen? I have been searching all over the internet for a solution for this but i am running out of ideas.

Android :: List View On Item Click Listener Not Working

Sep 6, 2010

What Iīm trying to do is to create a list (using a list view) of items (which are views inflated from the same layout) what must be clickable. At first I thought that all I had to do was to add an onItemClickListener to the ListView so if the used clicked on any of the views that composed this Item the listener would react. Well, I was wrong. Iīve tried a lot of things, including setting focus and focusontouchmode off for each of the views that compose the itemīs view but it still doesnīt work. Any tips here? Can I archive this result? Oh, also ... this list view is in a dialog and the listener is in the activity that builds the dialog.

Android :: Custom List View / Set On Item Selected Listener Not Working

Sep 2, 2010

I'm just beginning Android development, and I'm working to get a Custom list view with a checkbox working. I've created a base class that extends Activity, Created an Adapter and overrode the getView() method to add the checkbox to the list view. I'm assuming I need to do this because I need something equivalent to didSelectRowIndexAtPath from Obj C to update my model. Please let me know if there's an alternate way of doing this too Code...

Android :: Changing Background Color On Selected List View Item

Apr 17, 2009

Im trying to change background color when an item is selected. Something like using a color selector, but actually it crashes. I've created a list_selector.xml inside /res/color/.<?xml version="1.0" encoding="UTF-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android"><item android:state_focused="true" android:color ="@ color/ plain_yellow"/><item android:state_pressed="true" android:state_enabled="false" android:color ="@color /plain _yellow" /><item android:state_enabled="false" android:color="@color/ plain_yellow" /><item android: state_active="true" android:color="@color/ plain_yellow" /><item android:color="@android: color/ transparent" /></selector> plain_yellow is a color i've defined in /res/values. I've tried to assign that selector programatically and using the xml, but the app crashes. Am i doing something wrong?

Android :: List Item View Order Changes When Scrolling Fast In ListView

Sep 2, 2010

I am new to android, and ended up (have to) ask a question here. Let's make it simple, I simply want to make my own TextView-like (MyView extends View), This is my code:

public class MyView extends View { private Paint mPaint;
private String mText; private Bitmap mBitmap1; private Bitmap mBitmap2;
public MyView(Context context) { super(context); initView(); }
public MyView(Context context, AttributeSet attrs) { super(context, attrs);
initView(); } private final void initView() { mPaint = new Paint(); }
public void setText(String text) { mText = text; }
@Override protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
int measuredWidth = measureWidth(widthMeasureSpec);
if (mBitmap1 == null) initBitmap1(measuredWidth);
int measuredHeight = measureHeight(heightMeasureSpec);
setMeasuredDimension(measuredWidth, measuredHeight);
}

private void initBitmap1(int measuredWidth) {
mBitmap1 = Bitmap.createBitmap(measuredWidth, Fonts.getHeight(), Bitmap.Config.ARGB_4444);
Canvas canvas = new Canvas(mBitmap1 ); canvas.drawText(mText, 0, 0, mPaint);
} private void initBitmap2() {
mBitmap2 = Bitmap.createBitmap(30, Fonts.getHeight(), Bitmap.Config.ARGB_4444);
Canvas canvas = new Canvas(mBitmap2); canvas.drawText(mText, 0, 0, mPaint);
} private int measureWidth(int widthMeasureSpec) {
int measuredWidth = 0; int specWidthMode = MeasureSpec.getMode(widthMeasureSpec);
int specWidthSize = MeasureSpec.getSize(widthMeasureSpec);

if (specWidthMode == MeasureSpec.EXACTLY) { measuredWidth = specWidthSize;
} else { measuredWidth = getWidth(); if (specWidthMode == MeasureSpec.AT_MOST) {
measuredWidth = Math.min(measuredWidth, specWidthSize);
} } return measuredWidth; }
private int measureHeight(int heightMeasureSpec) {
int measuredHeight = 0; int specHeightMode = MeasureSpec.getMode(heightMeasureSpec);
int specHeightSize = MeasureSpec.getSize(heightMeasureSpec);
if (specHeightMode == MeasureSpec.EXACTLY) { measuredHeight = specHeightSize;
} else { measuredHeight = 80; if (specHeightMode == MeasureSpec.AT_MOST) {
measuredHeight = Math.min(measuredHeight, specHeightSize);
} } return measuredHeight;
} @Override protected void onDraw(Canvas canvas) {
super.onDraw(canvas); canvas.drawBitmap(mBitmap1, getLeft(), 0, mPaint);
initBitmap2(); canvas.drawBitmap(mBitmap2, getLeft(), 30, mPaint);
} }
In my code, I populate some numbers of MyView (let's say 20) in a ListActivity. My question is why mBitmap1's order changes randomly while i scroll (up-down) fastly (if I scroll slowly, this problem not occur)? mBitmap2 stays where those should be.

Android :: Check A Particular Item In A Checked ListView?

Oct 11, 2010

I am using a ListView in which only one item can be checked at a time.

This is my custom list_row.xml :

CODE:..........

I populate the list in onCreate() using a normal array adapter :

CODE:............

When the list is displayed, I want to have, say the 5th item, in the list as Checked. How can I go about doing this? I know CheckedTextView has a function called setChecked(), but how can I get my 5th item from the list to apply this function on it?

Android :: Find Item In List Without Filtering List But Just Scrolling To That Item

Oct 17, 2010

Trying to implement simple dictionary. I want to make it so while the user is typing in the EditText box the list to scroll automatically to the best match. I don't want it to filter the list. For example if the user types "s" in the EditText I want the first word that s/he sees under the EditText box to be the first word in the dictionary that starts with "s." But the user should still be able to slide up and down and to be able to see the entire list of words. It is basically like a go to functionality. I used ArrayList to store my list of words. The data is in res/raw/data.xml file. Here is my onCreate method
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
wordListView = (ListView)findViewById(R.id.wordList);
myEditText = (EditText)findViewById(R.id.myEditText);
words = new ArrayList<Word>();
arrAdap = new ArrayAdapter<Word>(this, android.R.layout.simple_list_item_1, words);
wordListView.setAdapter(arrAdap); try {
InputStream inSource = getResources().openRawResource(R.raw.data);
DocumentBuilder builder = DocumentBuilderFactory.newInstance().newDocumentBuilder();
Document doc = builder.parse(inSource, null);
NodeList wordsList = doc.getElementsByTagName("eng-bg");
int length = wordsList.getLength();
for(int i = 0; i<length; i++) {
Element entry = (Element)wordsList.item(i);
Element eng = (Element)entry.getElementsByTagName("english").item(0);
Element bul = (Element)entry.getElementsByTagName("bulgarian").item(0);
Element id = (Element)entry.getElementsByTagName("ID").item(0);
String english = eng.getFirstChild().getNodeValue();
String bulgarian = bul.getFirstChild().getNodeValue();
int wordId = Integer.parseInt(id.getFirstChild().getNodeValue());
Word word = new Word(bulgarian, english, wordId);
addNewWord(word);
} catch (ParserConfigurationException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SAXException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}wordListView.setOnItemClickListener(new OnItemClickListener(){
public void onItemClick(AdapterView<?> parent, View view, int pos, long id) {
selectedWord = words.get(pos);
showDialog(TRANS_DIALOG);
myEditText.setText(selectedWord.getEnglish());
myEditText.addTextChangedListener(new TextWatcher(){
public void onTextChanged(CharSequence s, int start, int before, int count) {
@Override
public void afterTextChanged(Editable s) {
// TODO Auto-generated method stub
@Override
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
// TODO Auto-generated method stub

Android :: Wrong Item Checked When Filtering ListView

Mar 21, 2010

The problem is that when I filter the list the entries switch position in the list view. Take for example three entries: 'A', 'B' and 'C' where 'C' is checked beforehand (i.e. the entry at position 3 in the list). When I type a 'C' on the keyboard, only the 'C' entry is displayed (as intended). Now 'C' is not checked anymore, since the entry has moved from the checked position 3 to the unchecked position 1 in the list.This behavior leads to some not very welcome effects in the app. Is there a way to "move the selection with the filtering", i.e. bind the checked state to the entry and not to its initial position in the list? Or do I need to find a new approach?

Android :: Designing Screens / Icons Display For List View

Sep 29, 2010

I never do graphics type programming. I'm designing a screen that will need to look good on all phones, and all resolutions. It's for displaying in a list view, and there will be a small graphic for the summary view, and a larger graphic for the detail view. Normally I use a 32x32 (res 72x72ppi).png for the summary view which looks good on my G1. The second image is for the detail view and it basically should fill the entire width of the screen (roughly, it's ok if it doesn't use the entire width as long as none of it is chopped off). The size I use for my G1 is 468x60.

So, the question for the guys that really know this stuff is: What sizes do I need to make these images to support all screens and densities with the fewest number of images? I know that the answer is a little subjective, but I remember seeing a post with a link to a page that recommended 3 different images for the different screens (and it seemed to make sense when I read it), and I think but don't remember for sure that then you would need 6 layouts to support those with both landscape and portrait orientations.
