Is there any way that I can get the image path from drawable folder in android as String. I need this because I implement my own viewflow where I'm showing the images by using their path on sd card, but I want to show a default image when there is no image to show.
Any ideas how to do that?
These all are ways:
String imageUri = "drawable://" + R.drawable.image;
Other ways I tested
Uri path = Uri.parse("android.resource://com.segf4ult.test/" + R.drawable.icon);
Uri otherPath = Uri.parse("android.resource://com.segf4ult.test/drawable/icon");
String path = path.toString();
String path = otherPath .toString();
I think you cannot get it as String
but you can get it as int
by get resource id
:
int resId = this.getResources().getIdentifier("imageNameHere", "drawable", this.getPackageName());
based on the some of above replies i improvised it a bit
create this method and call it by passing your resource
Reusable Method
public String getURLForResource (int resourceId) {
//use BuildConfig.APPLICATION_ID instead of R.class.getPackage().getName() if both are not same
return Uri.parse("android.resource://"+R.class.getPackage().getName()+"/" +resourceId).toString();
}
Sample call
getURLForResource(R.drawable.personIcon)
complete example of loading image
String imageUrl = getURLForResource(R.drawable.personIcon);
// Load image
Glide.with(patientProfileImageView.getContext())
.load(imageUrl)
.into(patientProfileImageView);
you can move the function getURLForResource to a Util file and make it static so it can be reused
If you are planning to get the image from its path, it's better to use Assets instead of trying to figure out the path of the drawable folder.
InputStream stream = getAssets().open("image.png");
Drawable d = Drawable.createFromStream(stream, null);
First check whether the file exists in SDCard. If the file doesnot exists in SDcard then you can set image using setImageResource() methodand passing default image from drawable folder
Sample Code
File imageFile = new File(absolutepathOfImage);//absolutepathOfImage is absolute path of image including its name
if(!imageFile.exists()){//file doesnot exist in SDCard
imageview.setImageResource(R.drawable.defaultImage);//set default image from drawable folder
}
