Glide Callback After Success In Kotlin

private SimpleTarget target = new SimpleTarget() { @Override public void onResourceReady(Bitmap bitmap, GlideAnimation glideAnimation) { // do s

Solution 1:

 Glide.with(context)
        .load(url)
        .listener(object : RequestListener<Drawable> {
            overridefunonLoadFailed(p0: GlideException?, p1: Any?, p2: Target<Drawable>?, p3: Boolean): Boolean {
                TODO("not implemented") //To change body of created functions use File | Settings | File Templates.
            }
            overridefunonResourceReady(p0: Drawable?, p1: Any?, p2: Target<Drawable>?, p3: DataSource?, p4: Boolean): Boolean {
                Log.d(TAG, "OnResourceReady")
                //do something when picture already loadedreturnfalse
            }
        })
        .into(imgView)

With Glide you can add Listener to your chain, which monitor state of your image loading. You have to override two methods, in onResourceReady method you have callback that your image is already loaded and you can do something , for example hide loader or let finish animation from another view. In onLoadFailed you get information about some error while loading and also you can react somehow. This way you can avoid those errors.

Solution 2:

Android Studio 3.5 - Kotlin 1.3.41 - Glide 4.9.0

• add this dependency to your build.gradle under dependencies:

  implementation 'com.github.bumptech.glide:glide:4.9.0'

Go to the top of your class and add these imports (pay attention expecially to target class which is different from the kotlin target class annotation):

import com.bumptech.glide.Glide
import com.bumptech.glide.load.DataSource
import com.bumptech.glide.load.engine.DiskCacheStrategy
import com.bumptech.glide.load.engine.GlideException
import com.bumptech.glide.load.resource.gif.GifDrawable
import com.bumptech.glide.request.RequestListener
import com.bumptech.glide.request.target.Target
import android.graphics.drawable.Drawable
import android.support.graphics.drawable.Animatable2Compat

I've put some extra parameter as override(600, 600), if you don't need remove it..

// Start animation
        Glide
            .with(this)
            .load(R.drawable.tossina_pose1)
            .centerCrop()
            .override(600, 600)
            .placeholder(R.drawable.tossina_idle_0)
            .diskCacheStrategy(DiskCacheStrategy.ALL)
            .listener(object : RequestListener<Drawable> {
                overridefunonLoadFailed(p0: GlideException?, p1: Any?, p2: Target<Drawable>?, p3: Boolean): Boolean {
                    TODO("not implemented") //To change body of created functions use File | Settings | File Templates.
                }
                overridefunonResourceReady(p0: Drawable?, p1: Any?, p2: Target<Drawable>?, p3: DataSource?, p4: Boolean): Boolean {
                    (p0 as GifDrawable).setLoopCount(1)
                    p0.registerAnimationCallback(object : Animatable2Compat.AnimationCallback() {
                        overridefunonAnimationEnd(drawable: Drawable) {
                            println("animation ends")
                        }
                    })
                    returnfalse
                }
            })
            .into(img)

Some indications: R.drawable.tossina_pose1 is my GIF, you can put also gif local image like this example. The final line .into(img) have img that is my imageView

Solution 3:

The problem is that in the Java code, you used the type SimpleTarget as the type of target. This is a raw type (missing generic parameters), and is one of the big legacy problems in Java generics. Kotlin doesn't allow raw types, and this is why you got problems while converting.

To fix this, you should do the following in Java:

privateSimpleTarget<Bitmap> target = new SimpleTarget<Bitmap>() { ... }

Which will force you to add asBitmap() to your Glide call:

Glide.with(context)
        .load(uri)
        .asBitmap()
        .override(600, 600)
        .fitCenter()
        .into(target);

Now that your code is using generics safely, it can be translated to Kotlin without a problem:

Glide.with(context)
        .load(uri)
        .asBitmap()
        .override(600, 600)
        .fitCenter()
        .into<SimpleTarget<Bitmap>>(target)

For those who are using Glide 3.8:

 Glide.with(this)
      .load(imgUrl)
      .listener(object : RequestListener<String, GlideDrawable> {
                        overridefunonException(e: Exception?, model: String?, target: Target<GlideDrawable>?, isFirstResource: Boolean): Boolean {
                            returnfalse
                        }
                        overridefunonResourceReady(resource: GlideDrawable?, model: String?, target: Target<GlideDrawable>?, isFromMemoryCache: Boolean, isFirstResource: Boolean): Boolean {
                            returnfalse
                        }
                    })
       .into(image)

Solution 5:

If you only want to set the Bitmap into the ImageView using Glide then you can try out for a Extension Function in Kotlin with which you will only need to pass the parameters like uri/url or size.

For Example:

classKotlinActivity : AppCompatActivity() {

    var sampleImageView : ImageView? = nulloverridefunonCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_kotlin)
        sampleImageView = findViewById(R.id.imageView) as ImageView?
        sampleImageView?.setImage("https://kbob.github.io/images/sample-3.jpg")
    }

//Extension function for ImageViewfun ImageView.setImage(url:String, context:Context){
        Glide.with(context).load(url).into(this)
    }
}
