How to set the image from drawable dynamically in android?

Question

I am storing my project related images in drawable folder. Also I am storing the image names in string variable and dynamically I am trying to set those images to the imageview. But the image is not displaying. Please help me in this regard.

My Code:

int res = getResources().getIdentifier(imagename, "drawable", this.getPackageName());
imageview= (ImageView)findViewById(R.id.imageView);
imageview.setImageResource(res);

In the above code "imagename" is the string variable which contains the image name.

Try this:

String uri = "@drawable/myresource";  // where myresource (without the extension) is the file

int imageResource = getResources().getIdentifier(uri, null, getPackageName());

imageview= (ImageView)findViewById(R.id.imageView);
Drawable res = getResources().getDrawable(imageResource);
imageView.setImageDrawable(res);

hi i tried your code it is showing the error as android.content.res.Resources$NotFoundException: Resource ID #0x0 at line Drawable res = getResources().getDrawable(imageResource); plz help me – hemanth kumar Jul 31 '12 at 11:35
You need to change the uri for your image name. Like "@drawable/MYIMAGENAME.extension" – rfsbraz Jul 31 '12 at 11:37
image_url contains the image name as "image.png" – hemanth kumar Jul 31 '12 at 11:39
image_url should contain "@drawable/image.png" – rfsbraz Jul 31 '12 at 13:13

It worked for me without png extension, with extension it was giving me error. So you can try without extension – Sharjeel Ahmed May 23 '14 at 12:03

Without image extension its working good.Please remove the image extension from your code. Happy Coding :) – Priyanka Sep 24 '14 at 07:45

Why the extension is still in the comments? I lost time 'till I got it to work by removing the extension. Even though I upvoted your answer, please edit it. Happy Pi-day :) – dephinera Mar 14 '15 at 17:00

I was too getting #0x0 problem. when I initialized imageResource before "int imageResource = getResources().getIdentifier(uri, null, getPackageName());" it was solved. – Prashant Jan 27 '18 at 20:05

getDrawable(int) is deprecated. You should use getDrawable(int, Theme) instead. – Juan Saravia Dec 30 '15 at 18:48

Try this Dynamic code

String fnm = "cat"; //  this is image file name
String PACKAGE_NAME = getApplicationContext().getPackageName();
int imgId = getResources().getIdentifier(PACKAGE_NAME+":drawable/"+fnm , null, null);
System.out.println("IMG ID :: "+imgId);
System.out.println("PACKAGE_NAME :: "+PACKAGE_NAME);
//    Bitmap bitmap = BitmapFactory.decodeResource(getResources(),imgId);
your_image_view.setImageBitmap(BitmapFactory.decodeResource(getResources(),imgId));

In above code you will need Image-file-Name and Image-View object which both you are having.

This works for me (dont use the extension of the image, just the name):

String imagename = "myImage";
int res = getResources().getIdentifier(imagename, "drawable", this.getPackageName());
imageview= (ImageView)findViewById(R.id.imageView);
imageview.setImageResource(res);

Here is the best way that works in every phone at today. Most of those answer are deprecated or need an API >= 19 or 22. You can use the fragment code or the activity code depends what you need.

Fragment

//setting the bitmap from the drawable folder
Bitmap bitmap= BitmapFactory.decodeResource(getActivity().getResources(), R.drawable.my_image);

//set the image to the imageView
imageView.setImageBitmap(bitmap);

Activity

//setting the bitmap from the drawable folder
Bitmap bitmap= BitmapFactory.decodeResource(MyActivity.this.getResources(), R.drawable.my_image);

//set the image to the imageView
imageView.setImageBitmap(bitmap);

Cheers!

ImageView imageView=findViewById(R.id.imageView)

if you have image in drawable folder then use

imageView.setImageResource(R.drawable.imageView)

if you have uri and want to display it in imageView then use

imageView.setImageUri("uri")

if you have bitmap and want to display it in imageView then use

imageView.setImageBitmap(bitmap)

note:- 1. imageView.setImageDrawable() is now deprecated in java 2. If image uri is from firebase or from any other online link then use

    Picasso.get()
    .load("uri")
    .into(imageView)

(https://github.com/square/picasso)

or use

Glide.with(context)
            .load("uri")
            .into(imageView)

(https://github.com/bumptech/glide)

This solution worked for me. To add, if you need to clear the ImageView, just do: `imageView.setImageResource(android.R.color.transparent)` https://stackoverflow.com/a/8243184/1657502 – Antônio Medeiros Oct 12 '17 at 03:46

First of let's your image name is myimage. So what you have to do is that go to Drawable and save the image name myimage.

Now assume you know only image name and you need to access it. Use below snippet to access it,

what you did is correct , ensure you saved image name you are going to use inside coding.

public static int getResourceId(Context context, String name, String resourceType) {
    return context.getResources().getIdentifier(toResourceString(name), resourceType, context.getPackageName());
}

private static String toResourceString(String name) {
    return name.replace("(", "")
               .replace(")", "")
               .replace(" ", "_")
               .replace("-", "_")
               .replace("'", "")
               .replace("&", "")
               .toLowerCase();
}

In addition to it you should ensure that there is no empty spaces and case sensitives

As of API 22, getResources().getDrawable() is deprecated (see also Android getResources().getDrawable() deprecated API 22). Here is a new way to set the image resource dynamically:

String resourceId = "@drawable/myResourceName"; // where myResourceName is the name of your resource file, minus the file extension
int imageResource = getResources().getIdentifier(resourceId, null, getPackageName());
Drawable drawable = ContextCompat.getDrawable(this, imageResource); // For API 21+, gets a drawable styled for theme of passed Context
imageview = (ImageView) findViewById(R.id.imageView);
imageview.setImageDrawable(drawable);

and getIdentifier is also not recommended to use nowadays – Darksymphony Jan 28 '23 at 20:04 — Darksymphony, Jan 28 '23 at 20:04

This works fine for me.

final R.drawable drawableResources = new R.drawable(); 
final Class<R.drawable> c = R.drawable.class;
final Field[] fields = c.getDeclaredFields();
for (int i=0; i < fields.length;i++) 
{
     resourceId[i] = fields[i].getInt(drawableResources);  
    /* till here you get all the images into the int array resourceId.*/
}
imageview= (ImageView)findViewById(R.id.imageView);
if(your condition)
{
   imageview.setImageResource(resourceId[any]);
}
