Android :: Images Don't Display But TextView Contents Is Correct
Oct 29, 2010
I am working on an Android application that displays a list of items when a tab is selected, then displays detail information about an item that was selected from the list :
CODE:............
The details are to be displayed using ImageViews, ImageButtons, and TextViews. The data comes from a database query, so the TextView text and ImageView drawables have to be assigned dynamically.
The correct text from the database query gets assigned to each of the Views. I can see everything being added when I step through the code in the onCreate method of Activity3 in the debugger.
BUT, the drawables are only displayed when I select the first item in the ListActivity. If I select another item, all TextViews display the correct information but the drawables are not displayed for the ImageViews or ImageButtons. It looks like only the backgrounds are being displayed.
The ImageButton drawables are not being dynamically assigned, only the ImageView drawables are. The ImageButton drawables are set in the TableLayout XML that is associated with the activity. Here is one entry :
CODE:..............
Originally, I had android_drawable="@drawable/ic_phone", then tried adding android:background="@drawable/ic_phone", and finally created the following selector (phoneselector.xml) :
If I select the first item again, its proper ImageView drawables are displayed along with the proper text in the TextViews. The ImageView drawables that belong to the other items have no problems being displayed in Activity2's ListView.
The code successfully sets an onClickListener for the button (also in Activity3.onCreate). If I click on what is displayed on the spot where the drawable should be, the phone number is dialed.
The code successfully sets an onClickListener for the button (also in DetailActivity.onCreate).
Has anyone seen anything like this before? I would appreciate any help figuring out what is wrong.
Here are more details because I wonder if the problem has to do with the use of the Views :
The Activity1 extends TabActivity and sets a TabHost view that contains a FrameLayout along with the TabWidget. Activity1 creates the tabs dynamically.
Activity2 extends ListActivity and sets the content to its ListView (via setContentView(getListView()).
When ListActivity.onListItemClick is invoked (item in list is selected), a new Intent is created that contains an identifier in a Bundle and Activity3 is started.
The started activity (in Activity3.onCreate...) sets the content to a TableLayout view defined in a .xml file (via setContentView(R.layout.details.xml).
Here is the code from Activity3.onCreate :
CODE:.................

I am trying to display images dynamically on a home screen widget. As RemoveViews offer a very limited set of methods to interact with the layout, I'm trying to use HTML to get the same effect.

Given the following HTML: <p>This is text and this is an image <img src="http://www.example.com/image.jpg" />.</p> Is it possible to make the image render? When using this snippet: mContentText.setText(Html.fromHtml(text));, I get a cyan box with black borders, leading me to believe that a TextView has some idea of what an img tag is.

I want to set a TextView with SpannableString which is from the method below: Html.fromHtml(String source, Html.ImageGetter imageGetter, Html.TagHandler tagHandler) But the ImageGetter here need to override the method below: public abstract Drawable getDrawable (String source) Because I need to get the drawable from the internet, I have to do it asynchronously and seems it is not.

It was my understanding that even though TextView is not a ScrollView, it has scrolling functionality built-in.
However, I'm not able to scroll the contents of a TextView (that's on 1.6). I've reduced my code to the most trivial example:
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/ android" android:layout_height="fill_parent" android:layout_width="fill_parent" android:orientation="vertical"> Code...
I then defined a really long string for testing, which I set on this text view using setText(). The text is too long for the TextView, but there is no way to scroll it. So do I need to wrap it in a ScrollView after all?

I want to display search result on the screen, I have implemented in such a way that. From the search form user fill the 'search field' and 'search location' I set values into bean and that bean is static so that I can access it from every where. Then I start search result screen intent using:
Intent mainIntent = new Intent(SearchVenueResults.this, SearchResults.class);
startActivity(mainIntent);
On the 'SearchResults' activity 'oncreate' method I load data on the behalf of static bean which values filled from search form and then display data.
@Override
public void onCreate(Bundle savedInstanceState) { loadDataAndSetupUI();
super.onCreate(savedInstanceState);
}
My question is is it the correct approach to use it or in Android there is another preferable approach?

I apologize if this code looks a bit like a mess (considering the length); I figured I'd just include everything that goes on in my program at the moment.
I'm attempting to create a fairly simple Tic Tac Toe app for Android. I've set up my UI nicely so far so that there are a "grid" of TextViews. As a sort of "debug" right now, I have it so that when one clicks on a TextView, it should display the value of buttonId in a message box. Right now, it displays the correct assigned value for the first element I click, but no matter what I click afterwards, it always just displays the first value buttonID had. I attempted to debug it but couldn't exactly find a point where it would pull the old value (to the best of my knowledge, it reassigned the value).
There's a good possibility I'm missing something small, because this is my first Android project (of any note). Can someone help get different values of buttonId to appear or point out the error in my logic? The code...

For some of the albums/songs it says Unknown Artist but when I look at the files they are all in the proper folders with correct names. I added music using DoubleTwist if that helps.

Android: How to display images from the web in a ListView? I have the following code to display image from a URL in an ImageView:
import java.io.IOException;
import java.io.InputStream;
import java.net.HttpURLConnection;
import java.net.URL;
import java.net.URLConnection;
import android.app.ListActivity;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.os.Bundle;
import android.widget.ImageView;
public class HttpImgDownload extends ListActivity {
/** Called when the activity is first created. */
@Override public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState); setContentView(R.layout.main);
Bitmap bitmap = // DownloadImage(
// "http://www.streetcar.org/mim/cable/images/cable-01.jpg");
DownloadImage( "http://s.twimg.com/a/1258674567/images/default_profile_3_normal.png");
ImageView img = (ImageView) findViewById(R.id.img); img.setImageBitmap(bitmap);
} private InputStream OpenHttpConnection(String urlString) throws IOException
{ InputStream in = null; int response = -1;
URL url = new URL(urlString); URLConnection conn = url.openConnection();
if (!(conn instanceof HttpURLConnection)) throw new IOException("Not an HTTP connection");
try{ HttpURLConnection httpConn = (HttpURLConnection) conn;
httpConn.setAllowUserInteraction(false); httpConn.setInstanceFollowRedirects(true);
httpConn.setRequestMethod("GET"); httpConn.connect();
response = httpConn.getResponseCode();
if (response == HttpURLConnection.HTTP_OK) { in = httpConn.getInputStream();
} } catch (Exception ex) { throw new IOException("Error connecting");
} return in; } private Bitmap DownloadImage(String URL) {
Bitmap bitmap = null; InputStream in = null;
try { in = OpenHttpConnection(URL);
bitmap = BitmapFactory.decodeStream(in);
in.close(); } catch (IOException e1) {
// TODO Auto-generated catch block e1.printStackTrace();
} return bitmap; } }
Now how can I display images in an array in a listview? Here's how I want to display the images:

I need to determine the screen density at runtime in an Android App Widget. I've set up an HDPI emulator device (avd). If set up a regular executable project, and insert this code into the on Create method: Similarly, if I get a resource at runtime using the Resources object obtained from context.get Resources() in the App Widget, it returns the wrong resource based on screen density. For instance, I have a 60x60px drawable for mdpi, and an 80x80 drawable for hdpi. If I get this Drawable object using context.get Resources().getDrawable(...), it returns the 60x60 version. Is there any way to correctly deal with resources at runtime from the context of an App Widget?

i have a spinner with an arrayadapter that is dynamically managed. when it gets displayed, the spinner text also displays the radio button. how do i get rid of this radio button?
NOTE: i'm not talking about the radio buttons that appear in the list that is displayed when i select the drop down on the spinner.
here is a pic of what it looks like: SIGH cannot upload image as i don't have 10 pts. so i've found a link: http://www.slashresources.com/android-gui-examples/ scroll down about 1/2 way and find the spinner example on that page. and my spinner looks like the spinner thats grayed out by the list. notice how the drop down arrow is all strecthed and yucky... thats my problem.
Here are the appropriate code snippet... couple of points:
This code is in the constructor of widget which is a subclass of Spinner value is an array of Object instances (passed when the widget gets created) there are no XML resources; all widgets are dynamically created thinking i need to "manipulate" the prompt, i added setPrompt(...) in the constructor and also in the onitemclicked event listener... this had no effect.
Q: what am i missing? seems to me i'm missing some attribute of the Spinner which is causing the radio button to also display in the text part of the spinner.

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