Setting Android images from string value

Question

Currently I\'m drawing a PNG image in my Android application like so:

ImageView image = new ImageView(context);
image.setImageDrawable(context.getResources(         


        

Answer 1

I'm using:

int resId = getResources().getIdentifier("testimage", "drawable", getPackageName());
image.setImageResource(resId);

"testimage" - corresponds to for instance testimage.jpg, i.e. dont include ".jpg"

"drawable" - is the resource type, like in: @drawable/testimage

Check Resources.getIdentifier(...)

Answer 2

There is a method for doing that, you can retreive resource IDs by string using Resources.getIdentifier() http://developer.android.com/reference/android/content/res/Resources.html

Something like:

int resourceId = Activity.getResources().getIdentifier("testimage", "drawable", "your.package.name");

Answer 3

String path = "sdcard/camera_app/name.jpg"; img.setImageDrawable(Drawable.createFromPath(path));

Answer 4

Put you images in the assets/ folder and open

image.setImageURI("file:///android_asset/" + nameFromDB);
