Android :: ListView Rounded Corner Hidden By List Item

Nov 8, 2010

I have this Listview element:

<ListView
android:id="@+id/category_list"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1"
android:background="@drawable/list_background"
android:layout_marginTop="10sp"
android:layout_marginLeft="10sp"
android:layout_marginRight="10sp"
android:drawSelectorOnTop="false"
android:listSelector="@drawable/list_item_background"
android:cacheColorHint="#FFFFFF"
android:clipToPadding="true"
android:focusable="true"
android:focusableInTouchMode="true"
android:clickable="true"a
ndroid:longClickable="true"
android:footerDividersEnabled="true"
android:headerDividersEnabled="true"
android:dividerHeight="1px" />

where list_background is:
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<corners android:radius="10dp" /> <solid android:color="#FFFFFF"/>
</shape>
The list view loads itself with the rounded corners, but then, the items of the list hide the round corners.

Android :: How To Expand ListView As List Item Populate?

Aug 23, 2010

Basically I am trying to recreate the default contact screen when you click on "+" button another row of Phone number added to the list. Right now I have an ImageView as the "+" button and a ListView to contain the list of phone numbers. The problem is that the ListView doesn't expand when I add more item into the list. I could build the same look with LinearLayout but how can I save all those numbers that way? Below is the layout of the item that will be inflate with custom Adapter:

<?xml version="1.0" encoding="utf-8"?> <TableLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content" android:layout_height="60px"
android:stretchColumns="1" android:background="#FFFFFFFF"
android:gravity="center_vertical"> <TableRow>
<Button android:id="@+id/type" android:layout_width="wrap_content"
android:layout_height="wrap_content" android:paddingLeft="10dp"
android:text="Home" /> <RelativeLayout android:layout_width="fill_parent"
android:layout_height="wrap_content" android:paddingLeft="10dp"
android:paddingRight="10dp" >
<EditText android:id="@+id/value" android:layout_width="fill_parent"
android:layout_height="wrap_content" android:layout_alignParentTop="true"
android:layout_alignParentLeft="true" android:text="" android:hint="Name"
android:lines="1" android:textSize="10pt" android:typeface="sans"
android:textColor="#FF000000" android:gravity="left" /
</RelativeLayout> <ImageView android:id="@+id/del"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:layout_alignParentRight="true" android:layout_alignParentTop="true"
android:paddingRight="14dp" android:src="@android:drawable/ic_delete" />
</TableRow> </TableLayout>

This is the ListView portion.
<ListView android:id="@+id/phoneList" android:layout_width="fill_parent"
android:layout_height="wrap_content" android:background="#FFFFFFFF"
android:scrollbars="none" />

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 :: 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 :: 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 :: 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 :: Way To Present List To User Where Each Item On List Starts An Activity When Selected

I am on my first Android application and I am on a timeline so details and examples will be useful since my knowledge is still minimal. I want my first screen to present the user with a list of activities to choose from. In my situation it is a recipe app where the user first chooses the type of food, such as, Beef, Chicken, or Pork. I want the application to launch an activity depending on the list item that the user clicked on. I am not sure if I should use a list view, a text view, a scroll view, a list activity, an activity group...

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 :: Focus In List When First List Item Should Be Disabled

Aug 23, 2010

I use tabs in my Android application and one of my tabs contains a listview. I'm noticing some weird behavior when I override isEnabled in my list's adapter and then try to use the D-pad to move up and down through the list and to my tabs.If the 0th item of the list is enabled, then everything works as expected - I can move down through the list, and then up again and once I reach the top of the list, pressing up moves focus to my tab.However, if the 0th item is DISABLED (isEnabled in my adapter returns false), then when I press up while position 1 is focused, the focus gets stuck. It doesn't move up to the tab as I would have expected and instead stays on position 1 of the list.
