Glide-4.0.0 Missing placeholder, error, GlideApp and does not resolve its method placeholder,error

问题:

I want to use Glide Android library to download image and show in ImageView.

in previous version we used:

Glide.with(mContext).load(imgUrl)                 .thumbnail(0.5f)                 .placeholder(R.drawable.PLACEHOLDER_IMAGE_NAME)                 .error(R.drawable.ERROR_IMAGE_NAME)                 .crossFade()                 .diskCacheStrategy(DiskCacheStrategy.ALL)                 .into(imageView); 

But I have seen Glide documentation:

it says use GlideApp.with() instead Glide.with()

my concern is missing placeholder, error, GlideApp and other options.

I am using

 compile 'com.github.bumptech.glide:glide:4.0.0' 

Where am I doing wrong? with reference here

how GlideApp.with() has been used??

The API is generated in the same package as the AppGlideModule and is named GlideApp by default. Applications can use the API by starting all loads with GlideApp.with() instead of Glide.with():

GlideApp.with(fragment)    .load(myUrl)    .placeholder(placeholder)    .fitCenter()    .into(imageView);

Try using RequestOptions:

RequestOptions requestOptions = new RequestOptions(); requestOptions.placeholder(R.drawable.ic_placeholder); requestOptions.error(R.drawable.ic_error);  Glide.with(context)      .setDefaultRequestOptions(requestOptions)      .load(url).into(holder.imageView); 

EDIT

If .setDefaultRequestOptions(requestOptions) does not work, use .apply(requestOptions):

Glide.with(MainActivity.this)             .load(url)             .apply(requestOptions)             .into(imageview);  // or this  Glide.with(MainActivity.this)             .load(url)             .apply(new RequestOptions().placeholder(R.drawable.booked_circle).error(R.drawable.booked_circle))             .into(imageview);

If you use Glide package dependences compile 'com.github.bumptech.glide:glide:3.7.0' than use should to use below code

GlideApp     .with(your context)     .load(url)     .centerCrop()     .placeholder(R.drawable.loading_image)     .error(R.drawable.error_image)     .into(myImageView); 

Note: As in doc

Round Pictures: CircleImageView/CircularImageView/RoundedImageView are known to have issues with TransitionDrawable (.crossFade() with .thumbnail() or .placeholder()) and animated GIFs, use a BitmapTransformation (.circleCrop() will be available in v4) or .dontAnimate() to fix the issue.

Latest update version compile com.github.bumptech.glide:glide:4.1.1 than use should to use below code

Glide.with(this)      .load(url)      .apply(new RequestOptions()                 .placeholder(R.mipmap.ic_loading_image)                 .centerCrop()                 .dontAnimate()                 .dontTransform())      .into(imageView);

If you wanna use GlideApp you have to add to dependencies annotation processor like on the screenshot

then include an AppGlideModule implementation in your application:

@GlideModule public final class MyAppGlideModule extends AppGlideModule {} 

Do not forget about the @GlideModule annotation. Then you need to Build project. And GlideApp will be automatically generated. Hope this is still helpful.

dependencies

compile 'com.github.bumptech.glide:glide:4.1.1' annotationProcessor 'com.github.bumptech.glide:compiler:4.1.1' 

add an appropriately annotated AppGlideModule implementation

import com.bumptech.glide.annotation.GlideModule; import com.bumptech.glide.module.AppGlideModule;   @GlideModule public final class MyAppGlideModule extends AppGlideModule{} 

In addition, if you have used the jack option, in order to avoid the following similar errors, you need use Android Studio 3.0.0 preview.

Error:Execution failed for task ':app:transformJackWithJackForDebug'. com.android.jack.ir.JNodeInternalError: java.lang.Exception: java.lang.AssertionError: No yet implemented

We have no need to use RequestOptions also.

The generated API adds a GlideApp class, that provides access to RequestBuilder and RequestOptions subclasses. The RequestOptions subclass contains all methods in RequestOptions and any methods defined in GlideExtensions. The RequestBuilder subclass provides access to all methods in the generated RequestOptions subclass without having to use apply:

Using Glide :-

A request without the generated API might look like this:

Glide.with(fragment)     .load(url)     .apply(centerCropTransform()         .placeholder(R.drawable.placeholder)         .error(R.drawable.error)         .priority(Priority.HIGH))     .into(imageView); 

Using GlideApp :-

With the generated API, the RequestOptions calls can be inlined:

GlideApp.with(fragment)     .load(url)     .centerCrop()     .placeholder(R.drawable.placeholder)     .error(R.drawable.error)     .priority(Priority.HIGH)     .into(imageView); 

You can still use the generated RequestOptions subclass to apply the same set of options to multiple loads, but generated RequestBuilder subclass may be more convenient in most cases.
