I have a picture in res/drawable directory: res/drawable/picture.jpeg.
Can I dynamically update this picture.jpeg from code? i.e. I want to use another picture to replace this picture in the drawable directory dynamically. If I can, what path should I use to access the picture? Should I use "res/drawable/picture.jpeg"?

Is it possible to have subfolders in the /res/drawable directory. I would like my resources to be organized in a tree view and not in a flat dir. If it is possible so how do I reference the resource from the code?
I have no trouble using mutate() in my Java code to modify a drawable but I was wondering if there was a way designate a drawable in XML code as mutable ( in the src tag for example ).

A number of images are "built in" to my app. They are stored in the drawable folder. I'd like to give the option of sending one of these images via mms (or even email) to someone in the user's address book. All the examples I've seen are sending images that are stored somewhere other then the default Eclipse drawable folders.
View 1 Replies View RelatedI have an app that I started in 1.6. It used images that were specific to portrait and landscape layouts. I put these in the corresponding drawable folders, for example:
drawable/image01,png
drawable-land/image01.png
when I created a new project with 2.0 it gave me the following folders. drawable drawable-hdpi drawable-mdpi drawable-lpdi. when I look at the documentation around these folders it all seems very straight forward. I assumed that you were able to create the following folders. drawable-hdpi-land drawable-mdpi-land drawable-lpdi-land
and everything would work as before. The image directory would swap automagically pulling the appropriately laid out image depending on your screen orientation. Unfortunately it does not. The SDK seems to get confused, and if I clean the project, the folders come up as poorly named.
I want to show image from drawable folder using path (res/drawable/icon.png). I do not want to use R.drawable.icon. Please anybody know how to view the image using res/drawable/icon.png.
View 6 Replies View RelatedI am trying to create a drawable in code and change the color based on some criteria. When I try and set the Drawable as the background of the ImageView it displays but won't let me set any padding. I realized I need to set the ImageView image via the setImageDrawable() function in order to be able to set the padding. The problem I am running into is that when I set it via the setImageDrawable() function nothing is displayed.
Here is what I have written:
<?xml version="1.0" encoding="utf-8"?>
ImageView icon = (ImageView) row.findViewById(R.id.icon);
ShapeDrawable mDrawable; int x = 0; int y = 0;
int width = 50; int height = 50;
float[] outerR = new float[] { 12, 12, 12, 12, 12, 12, 12, 12 };
mDrawable = new ShapeDrawable(new RoundRectShape(outerR, null, null));
mDrawable.setBounds(x, y+height, x + width, y);
switch(position){ case 0: mDrawable.getPaint().setColor(0xffff0000); //Red break;
case 1: mDrawable.getPaint().setColor(0xffff0000); //Red break;
case 2: mDrawable.getPaint().setColor(0xff00c000); //Green break;
case 3: mDrawable.getPaint().setColor(0xff00c000); //Green break;
case 4: mDrawable.getPaint().setColor(0xff0000ff); //Blue break;
case 5: mDrawable.getPaint().setColor(0xff0000ff); //Blue break;
case 6: mDrawable.getPaint().setColor(0xff696969); //Gray break;
case 7: mDrawable.getPaint().setColor(0xff696969); //Gray break;
case 8: mDrawable.getPaint().setColor(0xffffff00); //Yellow break;
case 9: mDrawable.getPaint().setColor(0xff8b4513); //Brown break;
case 10: mDrawable.getPaint().setColor(0xff8b4513); //Brown break;
case 11: mDrawable.getPaint().setColor(0xff8b4513); //Brown break;
case 12: mDrawable.getPaint().setColor(0xffa020f0); //Purple break;
case 13: mDrawable.getPaint().setColor(0xffff0000); //Red break;
case 14: mDrawable.getPaint().setColor(0xffffd700); //Gold break;
case 15: mDrawable.getPaint().setColor(0xffff6600); //Orange break;
} icon.setImageDrawable(mDrawable); icon.setPadding(5, 5, 5, 5);
This results in a space for the ImageView but no image.
I have to make a dedicated image viewer app for Android 2.x.
There are too many jpeg image files: about 2000~ jpegs, over 100MB.
I want access the image files with their file names,
but I couldn't find such an example.
By the way, is it okay to put many image files in /res/drawable folder?
I heard that the android application cannot be installed on sdcard and
the program repository is very small so 100MB app cannot be installed generally.
I found some examples which download the large data files on sdcard online,
but I cannot run a web server to host the data files,
and I must upload the fully packaged program on Android Market. (Should I build one apk file?)
What are the best practices for managing too many resource images (or something) in Android?
How can i convert a Bitmap to Drawable.
View 2 Replies View RelatedI've got an app that is heavily based on remote images. They are usually displayed alongside some data in a ListView. A lot of these images are new, and a lot of the old ones will never be seen again.
I'm currently storing all of these images on the SD card in a custom cache directory (ala evancharlton's magnatune app).
I noticed that after about 10 days, the directory totals ~30MB. This is quite a bit more than I expected, and it leads me to believe that I need to come up with a good solution for cleaning out old files... and I just can't think of a great one. Maybe you can help. These are the ideas that I've had:
Delete old files. When the app starts, start a background thread, and delete all files older than X days. This seems to pose a problem, though, in that, if the user actively uses the app, this could make the device sluggish if there are hundreds of files to delete. After creating the files on the SD card, call new
File("/path/to/file").deleteOnExit(); This will cause all files to be deleted when the VM exits (I don't even know if this method works on Android). This is acceptable, because, even though the files need to be cached for the session, they don't need to be cached for the next session. It seems like this will also slow the device down if there are a lot of files to be deleted when the VM exits. Delete old files, up to a max number of files. Same as #1, but only delete N number of files at a time. I don't really like this idea, and if the user was very active, it may never be able to catch up and keep the cache directory clean.
I read about in the google documents that the 3 folders corresponds to different screen types and that android would select the image from different folders automatically according to the screen type. I read that WVGA will load from drawable-hdpi and HVGA will load from drawable-mdpi. When I tested with 2 emulators both running 2.1, each with HVGA and WVGA. It turns out that they are both reading the image in mdpi. If I deleted the image in mdpi then they read from hdpi. Can someone answer why emulator with WVGA is reading from drawable- mdpi?
View 4 Replies View RelatedHow we can store image files(*.png) to the folder R.drawable at runtime?
View 2 Replies View RelatedIm making an app in which the user selects an image and then gets redirected to a new screen in which the drawable name is displayed.
This is the code triggered when the user click an image:
Code:
public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
Intent tabsIntent = new Intent();
tabsIntent.setClassName("com.budisha.app", "com.budisha.app.TabClassActivity");
tabsIntent.putExtra("pic_name", position); //sends picture position
startActivity(tabsIntent);
}
This sends the new activity the drawable position. But i need to get the drawable name.
If I want to get an image from drawable folder I do this:
getResources().getDrawable(R.drawable.myimage)
But if I want to get an image in a folder like this:
drawable/pngs/myimage.png
How I can get that image?
I have an image on a private file.
I read the file, create the drawable, and assign it to an ImageView.
The ImageView has WRAP_CONTENT so the size is automatic.
On 320x480 screens, the image looks good
But on screens with more resolution and high density 480x800 or 480x854 (N1, droid) , when the image is for example 150x150, I see the image as 100x100.
Of course it has something to do with the density but not sure how should I resolve this.
This is my code...
if I then inspect the size of the icon, android thinks the size is 100x100, when really is 150x150.
Looks like its reducing the image by the density.
Can anybody explain this and how to avoid this.
I need to know how he takes drawable object. I'm collecting some ImageView objects in array, they have background images that are rather big in resolution so they take lot of memory...
I have read somewhere that it will automatically create image with resolution that my imageView have, so i think it will take less memory than first one. Please tell me, if i set scaleType property, will it scale that image? Will that help me to save memory?
I have a custom drawable, where I draw a base bitmap image, then part of an image over the top of that that is clipped to a certain rectangle. For the overlayed image, I am trying to blur the edges, and I thought I could accomplish that using a BlurMaskFilter, however, I'm not seeing any blurring occurring.
Here is the content of the draw method from my Drawable class.The result is almost correct, except the overlay image is not being blurred.
m_paint = new Paint();
m_blurPaint = new Paint();
m_blurPaint.SetMaskFilter(new BlurMaskFilter(blurRadius, BlurMaskFilter.Blur.Outer));
[code]...
This code is written in C# using Xamarin, so I realize that some things are slightly different, but the overall methods will be the same.
I'd like to delete a image from the drawable folder in the decompiled apk, is there a easy way to remove all references to the image so I'll be able to recompile it with apktool without error?

View 4 Replies View RelatedAt some points while running my android application, I need to create a directory on the sd card, for a small number of users this fails and I can't figure out the reason for it... (I've found similar problems caused by the WRITE_EXTERNAL_STORAGE permission missing, it's there and it works for almost all users so I don't think this is reason) When mkdirs returns false I crash the program and log the following java.io.File properties, starting at the directory I want to create, then recursive printing properties of the parent directory and so on...
/sdcard/MyDirectory/Dir1/Dir2 (exists: false, canWrite: false, isDirectory: false, isFile: false);
/sdcard/MyDirectory/Dir1 (exists: true, canWrite: true, isDirectory: true, isFile: false);
/sdcard/MyDirectory (exists: true, canWrite: true, isDirectory: true, isFile: false);
/sdcard (exists: true, canWrite: true, isDirectory: true, isFile: false);
/ (exists: true, canWrite: false, isDirectory: true, isFile: false);
The strange thing is that the parent directory is writable (canWrite=true), I can't print the execute file permission but from what I've read, write is what you need when creating directories... What I've looked at so far is the WRITE_EXTERNAL_STORAGE permission, if the sd card is full and if the sdcard is mounted read only:...........................
I have an app that instructed me to copy some data from my computer to the SDCard. So I plugged the Droid into the computer, mounted my Droid SDCard, looked at the directory, and copied the file. There are a bunch of files and folders listed (e.g. backups for apps, album artwork, etc.) as being on the SDCard. But when I go into Astro on the Droid and select "SDCARD" it shows "directory is empty." I don't get it. Why can't I see the folders and files on the SDCard that I can see on the computer screen?
