Android :: Display Image From URL - Sizing And Screen Orientation?
Aug 30, 2010
I am trying to display an image from a URL, which may be larger than the screen dimensions. I have it kind of working, but I would like it to scale to fit the screen, and I also have problems when the screen orientation changes. The image is tiny, and I would like it to scale its width to the screen as well. (In both cases, I would like the image to fill the screen width with scrollbars (if necessary for height).
Here is my ImageView:
CODE:..............
Here is the java code which loads the image: (some error handling code removed for simplicity)
CODE:.........
I have tried different settings for android:scaleType. I'm sorry if this question has been asked before. I've gone through a number of tutorials on the subject, but they don't seem to work for me. Not sure if it has anything to do with the way the image is loaded. (from the web instead of a local resource)
Another issue is that sometimes the image doesn't even load. There are no runtime errors, I just get nothing in the ImageView.

Just wondering if its possible to use the built in image viewer to display an image sourced from a database. I'm hoping I can pass the byte[] as an extra to the ACTION_VIEW intent, but can't find any docs on it so far. Alternatively I'll have to roll my own viewer or first write the image out to a file and pass that to the intent.

I have an application that works fine with smaller images (say 1024x768 or so) but when you rotate the phone into a different orientation (say landscape to portrait) mode with a larger image on the screen, and then call ImageView.setImageUri() it goes into the BitmapFactory.class and never returns.So the app eventually times out. Never throws an exception, just never returns. Has anyone else seen this? Sounds like a bug in the Android code more than something I am doing since it works fine for smaller images.

I have a TableLayout with three columns that represents a form with
requiredSymbol | label | inputfield.
I want the input field to fill the remaining width of the screen right to the label. So far the only solution I found is this
CODE:....................
The maxWidth needs to be there are some value, which is actually ignored. Then the stretchColumns value does its thing nicely. Note that this also works if the content of the EditText would otherwise make the table span beyond the screen border (imho a bug..).
This works nicely now but seems a little bit of a hack to me. Is there a better way?

I'm trying to accomplish something fairly simple but struggling to get the right combination of layoutWidth/weight to make this work.
I have a horizontally oriented LinearLayout with width fill_parent containing two TextViews. The TextView on the right has variable width text, and I want the TextView on the left to adjust its size accordingly to as much width as possible. Essentially, the right TextView must always show all of its contents and the left TextView should extend as far as possible to the edge of the TextView on the right.

To use as an example: lets say that I have 2 EditTexts and one Button that I'm using as a login form. I want the EditTexts to be the same size, one after the other, with the login Button half their widths. Something like this:
The only way that I've been able to find to make the button 1/2 the width (but still maintain it's dynamic sizing) is to use a TableLayout with an empty view as the first field. Something like this:
CODE:.............
That feels like a god-awful hack and there has GOT to be a better way. Do you know of one?

I want to display an image from a url, for this I defined the ImageView first as,
<ImageView android:id="@+id/imagename" android:layout_width="wrap_content" android:layout_height="wrap_content" />
then in the activity,
super.onCreate(savedInstanceState); setContentView(R.layout.main); ImageView imgV = (ImageView)findViewById(R.id.imagename);
Now how should I supply the url of the image from where it should fetch the image ever time. I have seen the function setImageURI but it is not clear how to give the url.Any clues?

I'm having trouble displaying SOME images on my android app. Just normal display image from certain URL. Some images works, some just doesn't work. For instance try displaying this image from URL:
http://img191.imageshack.us/img191/7379/tronlegacys7i7wsjf.jpg
It doesn't work. Doesn't even work in emulator.Could it be the EXIF info for the image is problematic? Can anyone try to see they are able to display that image on android app, and share the code/method to display that image on screen?

is it possible to manually rotate the screen or fix the current screen orientation (with a key/button)? because it really annoys me having taken portrait pictures that cannot be viewed (with the media gallery application) in a portrait fashion on the milestone. this is because it always rotates the portrait picture back to landscape when rotating the milestone from landscape to portrait. right now there is no way of properly viewing portrait pictures on the milestone other than tilting your head (holding the milestone landscape and tilting your head along).this cannot be the way it was intended to be, right? or do I have to get a different viewing software which allows you to choose screen orientation? is there such an app?

When I started to display an image from the SDCARD in WebView, I got errors like:
" Not allowed to load local resource: file://".
I�ve found a solution for this, and you don�t even have to care about ContentProviders�
Here�s an example:
/* Using WebView to display the full-screen image */
WebView full = (WebView)findViewById(R.id.webview);
/* Set up the Zoom controls */
FrameLayout mContentView = (FrameLayout) get Window().
getDecorView().findViewById(android.R.id.content);
final View zoom = this.full.getZoomControls();
mContentView.addView(zoom, ZOOM_PARAMS);
zoom.setVisibility(View.VISIBLE);
/* Create a new Html that contains the full-screen image */
String html = new String();
html = ("<html><center><img src=""+fileName+""></html>" );
/* Finally, display the content using WebView */
full.loadDataWithBaseURL("file:///sdcard/data/data/com.youproject.example "utf-8",
""); Hope you found it useful, let me know how it works for you!

I'm trying to get the real size of an image displayed in an image view. Actually my image is larger than the screen and the imageview is resizing the image to diplay it. I'm looking for this new size.I've tried to override the onDraw method of the ImageView in a custom view but I'm not getting the correct height and width.

I am writing an Android app that includes an ImageView.The image to be included in the view resides on the local app directory of the emulator.The image is not being displayed in the view.The relavent XML and method used to display the image are given below.The image file is a "png" format file and is able to be opened from the local app directory. The path returned by getFilesDir() includes the full path, "/data/data/net.vitalrecord.android/files." This path designation does not exist on the development system but does exists when DDMS File Explorer is used.

<ImageView
id=*"@+id/batteryLevelview"*
android:layout_width=*"wrap_content"*
android:layout_height=*"wrap_content"*
android:layout_gravity=*"center"*/>
</FrameLayout>
</LinearLayout>

I have the url of an image. What i need to do is launch the default image viewer for images using an intent. But it doesn't work. If I do not specify the type of data, the intent launches the browser since the data is a url. It works basically (since you can see the image on the browser) but what I would like is to have the gallery display the image for me.I can also download the image into a Bitmap but I would still not know how to display the Bitmap using the gallery (if that's even possible).I tried saving the bitmap to the cache and then launch the viewer on that file but it doesn't work. Can you spot any mistakes on my code? (The Utilities class is a class i wrote.
