How to add an image to the drawable folder in Android Studio?

For Android Studio 1.5:

1. Right click on res -> new -> Image Asset
2. On Asset type choose Action Bar and Tab Icons
3. Choose the image path
4. Give your image a name in Resource name
5. Next->Finish

Update for Android Studio 2.2:

1. Right click on res -> new -> Image Asset

2. On Icon Type choose Action Bar and Tab Icons

3. On Asset type choose Image

4. On Path choose your image path

5. Next->Finish

The image will be saved in the /res/drawable folder.

Warning!
If you choose to use images other than icons in SVG or PNG be aware that it could turn grey if the image is not transparent. You can find an answer in comments for this problem but none of these are verified by me because I never encountered this problem. I suggest you to use icons from here: Material icons

Android : Share drawable resource with other apps

You can't pass a bitmap to an intent.

From what I see you want to share a drawable from your resources. So first you have to convert the drawable to a bitmap. And then You have to save the bitmap to the external memory as a file and then get a uri for that file using Uri.fromFile(new File(pathToTheSavedPicture)) and pass that uri to the intent like this.

shareDrawable(this, R.drawable.dish, "myfilename");

public void shareDrawable(Context context,int resourceId,String fileName) {
    try {
        //convert drawable resource to bitmap
        Bitmap bitmap = BitmapFactory.decodeResource(context.getResources(), resourceId);

        //save bitmap to app cache folder
        File outputFile = new File(context.getCacheDir(), fileName + ".png");
        FileOutputStream outPutStream = new FileOutputStream(outputFile);
        bitmap.compress(CompressFormat.PNG, 100, outPutStream);
        outPutStream.flush();
        outPutStream.close();
        outputFile.setReadable(true, false);

        //share file
        Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND);
        shareIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(outputFile));
        shareIntent.setType("image/png");
        context.startActivity(shareIntent);
    } 
    catch (Exception e) { Toast.makeText(context, "error", Toast.LENGTH_LONG).show();
    }
}

Share drawable image to other apps properly (sharing PNG to Whatsapp fails without FileProvider)

I solved this by properly implementing a FileProvider! This guide helped me so much, but I'll give a brief summary here.

Within the application tag of your Manifest, start declaring your new FileProvider like so:

<provider
android:name="android.support.v4.content.FileProvider"
android:grantUriPermissions="true"
android:exported="false"
android:authorities="${applicationId}">

    <meta-data
        android:name="android.support.FILE_PROVIDER_PATHS"
        android:resource="@xml/file_provider_paths"/>

</provider>

Then, create a new directory called xml (control-click on your res in Android Studio and go to New > Directory). Then, create a new file within xml called file_provider_paths (control-click on the new xml directory, and go to New > File, and name it file_provider_paths.xml). Add this code to that new xml file:

<paths>
    <cache-path name="cache" path="/" />
    <files-path name="files" path="/" />
</paths>

Finally, use it in your MainActivity or wherever like so:

// create new Intent
Intent intent = new Intent();
intent.setAction(Intent.ACTION_SEND);

// set flag to give temporary permission to external app to use your FileProvider
intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);

// generate URI, I defined authority as the application ID in the Manifest, the last param is file I want to open
Uri uri = FileProvider.getUriForFile(this, BuildConfig.APPLICATION_ID, imageFile);
intent.putExtra(Intent.EXTRA_STREAM, uri);

// Set type to only show apps that can open your PNG file
intent.setType("image/png");

// start activity!
startActivity(Intent.createChooser(intent, "send"));

To get that imageFile from an image in my drawable directory, I first converted it to a Bitmap, and then onto a File object, like so:

// create file from drawable image
Bitmap bm = BitmapFactory.decodeResource(this.getResources(), R.drawable.yourbeautifulimage);

File filesDir = getApplicationContext().getFilesDir();
File imageFile = new File(filesDir, "ABeautifulFilename.png");

OutputStream os;
try {
    os = new FileOutputStream(imageFile);
    bm.compress(Bitmap.CompressFormat.PNG, 100, os); // 100% quality
    os.flush();
    os.close();
} catch (Exception e) {
    Log.e(getClass().getSimpleName(), "Error writing bitmap", e);
}

And you're done, every app can see your shared image now!

How do I add an image in the drawable folder to an ImageView in Android Studio 1.2?

try with this way of code there are three ways to set image on ImageView

imageView.setImageResource(R.drawable.play);

or

            <ImageView
            android:id="@+id/ivProfileBg"
            android:src="@drawable/image_name"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" />

or

              <ImageView
              android:id="@+id/ivProfileBg"
              android:background="@drawable/image_name"
              android:layout_width="wrap_content"
              android:layout_height="wrap_content" />

I can't add images in my android studio project

a easy way to import images is the Batch Drawable import. For this you need to install a plugin. Check this source. Hope it helps

How to access images from drawable folder in android studio according to my choice?

In your List Array processing class, define a Int array containing references to the images:

int imageRes[] = {R.drawable.image1, R.drawable.image2,...};

Now considering that only three indices are returned after processing:
ex:
indices[] ={1,5,6};
int imageArray[] - (Size can be three)

for(int i =0; i<3;i++){
imageArray[i] = imageRes[indices[i]];
}

Your ListView can contain one Image View. Create a custom adapter for the list view and pass imageArray as parameter.

Then you can set the Image for ImageView something like this:

imageView.setImageResource[imageArray[i]]
