I am attempting to create a very graphically intensive android application. Almost all of the UI is based on bitmaps and I would like to support as many different devices as possible and to have the app look great in all of them.Is it possible to embed different resolutions for each image and have a different image displayed on each device. I am aware of stuff like hdpi folders etc. as well has units like dip etc., but that still leaves too many variables as to how the image is displayed. I would like to not have the images scaled at all to avoid losing image quality.For instance on my high resolution device I would like an image to be exactly 100px and then on a medium resolution device I would like a lower resolution image to display and be exactly 80px. If I use display independent units, I cannot ensure that the images will be of a particular size.

tt.setText(o.getOrderTitle());

The problem is when scrolling; sometimes the correct image shows, but sometimes when scrolling back/forward, the images shows randomly and that is not associated with the row. The images are downloaded from the web.
I have a png and a jpg image on disk. I'd like to use any built-in intent (if any are available) to view the image (just a single one at a time). Something like this:
Intent intent = new Intent();
intent.setImagePath("/blah/myimage.jpg");
startActivity(intent);
is there a built-in intent in android to do this, or do I have to write my own image viewing-activity? It would be cool if there was one that had panning/zooming as found in WebView.
I want to show a button at the end of an android list view

I am developing an app in android, which basically visits a given url and downloads an image. Now i want to populate this downloaded image and show it in thumbnail view. I have tried out displaying the same from SD Card, but when i am doing the same for downloaded files, it doesn't seems to work.
public View getView(int position,View convertView,ViewGroup parent)
{
System.gc();
ImageView i = new ImageView(mContext.getApplicationContext());
if (convertView == null)
{
//imagecursor.moveToPosition(position);
//int id = imagecursor.getInt(image_column_index);
//i.setImageURI(Uri.withAppendedPath(MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI, ""+ id));
i.setImageBitmap(bitmap);
i.setScaleType(ImageView.ScaleType.FIT_CENTER);
i.setLayoutParams(new GridView.LayoutParams(100, 100));
}
else
{
i = (ImageView) convertView;
}
return i;
}
I am going to create a gallery view where the user shall switch between different pictures of products. On some of them is going to be a label like "sale" and a short discription. On startup I want to display a loading animation at that place until the product photo is downloaded.
Use layer list or state list for one product photo?
Could you please show me, how to set that up?
How to make that spinner spin?
How to turn it on or off (how to access the layer list through code)?
By the way, is "spinner" the best word for this? It seems to stand for several things. Feel free to edit this question, if I didn't hit the right words.

View 1 Replies View RelatedI want to scale and display images which are dynamically loaded to a certain maximum size. The way I'm doing this is to set the layout_width and layout_height of my ImageView to the maximum dimensions and setting the scaleType to "fitCenter".
But here's the problem. This is inside a RelativeLayout and I want to show text directly under the image. In portrait mode, the text is way at the bottom (because of the height I have set). So I want the ImageView to scale down to the actual visible image size which is what it would seem like adjustViewBounds="true" should do.
Am I wrong in this assumption? Or is there a better way to do what I'm trying to do? Because I've been unsuccessful to this point!
Can anyone show me documentation or give me a quick web sample of how to display an image from the web. I read up on the drawables section in the android reference, but I either missed it, or its covered in another section.

I'm experiencing kind of strange behavior of my application after hard Home button is pressed. When you press Home, everything is OK - my app goes to the background, showing Home screen. But if you try to choose my app in the main menu or in the list of last tasks it behaves like it was not started before and does not show the last activity you were on - it just starts from scratch, namely, shows the splash screen and starts next corresponding activities. Moreover, old activities of this app remain on the activities stack, and previous instance of the app is not terminated - so if you press Back for a few times you'll just run into those activities which were undoubtedly started during the previous session of work with my app. Splash screen activity is filtered by "android.intent.action.MAIN" filter and "android.intent.category.LAUNCHER" category. The strange thing is that all of that happens despite the fact that I do not intercept any Back key hits, or override any onPause or onResume methods. What's happening contradicts with my understanding of Android app lifecycle - I was sure that when you hit Home an app just goes to the background, and when you choose it in the menu later - it just unwinds and does not start anew. (Of course, unless stuff like that is stated in the app manifest or corresponding methods are overridden or something else). I also checked it for some other lifecycle events - such as changing orientation or flipping hard keyboard out - and none of those led to such strange results. It appears that the problem occurs when you try to start the app from main menu or menu of last applications.
