Picasso does not call onBitmapLoaded for the first time

Question

Picasso does not call onBitmapLoaded for the first time ,if you know, please tell me

        txtView = (TextView) centerRelative.getChildAt(i);
                Picasso.with(getBaseContext()).load(file[i-4]).into(new Target() {
                    @Override
                    public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from) {
                        txtView.setBackground(new BitmapDrawable(getResources(),bitmap));
//                      Not executing for the first time

                    }

                    @Override
                    public void onBitmapFailed(Drawable errorDrawable) {

                    }

                    @Override
                    public void onPrepareLoad(Drawable placeHolderDrawable) {
//                      executing for the first time
                    }
                });

Target target = new Target() {
                    @Override
                    public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from) {
                        txtView.setBackground(new BitmapDrawable(getResources(),bitmap));
                        logd("onBitmapLoaded");
                    }

                    @Override
                    public void onBitmapFailed(Drawable errorDrawable) {

                    }

                    @Override
                    public void onPrepareLoad(Drawable placeHolderDrawable) {

                    }
                };
                Picasso.with(getBaseContext()).load(file[i-4]).into(target);

Did you try adding a Log inside it, or your TextView? – Ümañg ßürmån Nov 02 '18 at 08:46 — Ümañg ßürmån, Nov 02 '18 at 08:46

Solution: You have to make some changes here:

Instead of writing:

new Target() {...}

inside your into(..), you must create a global object of Target class. Do not make it local object as it may be garbage collected. So,

Step1:

Make a Global object:

Target target = new Target() {
    @Override
    public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from) {
        ....
    }
    @Override
    public void onBitmapFailed(Drawable errorDrawable) {
        ....
    }
    @Override
    public void onPrepareLoad(Drawable placeHolderDrawable) {
        ....
    }
};

Finally, Use that Target In your into(...):

Picasso.with(getBaseContext()).load(file[i-4]).into(target);

Try it, Hope it helps.

Do you you have any error, or just nothing happens? Put up a log now and check please. – Ümañg ßürmån Nov 02 '18 at 09:10
first time call onPrepareLoad,go to anthoner activity,then go back call onBitmapLoaded – initialise Nov 02 '18 at 09:14
You mean to say that `onBitmapLoaded` is not called at all? untill I come back? – Ümañg ßürmån Nov 02 '18 at 09:19
Okay, Can you show the code where you have tried my solution? Pls edit in the question – Ümañg ßürmån Nov 02 '18 at 09:25
@initialise Please comment your older code from your program. – Ümañg ßürmån Nov 02 '18 at 09:33
This is not correct: `logd("onBitmapLoaded");` You must write like `Log.d("Log","onBitmapLoaded");` Try this and check. – Ümañg ßürmån Nov 02 '18 at 09:34
private void logd(String msg) { Log.d(TAG, msg); } it is my log – initialise Nov 02 '18 at 09:37
Alright my bad.. @initialise add a tag to your textview like this: `textview.setTag(target)` after the target object. and try. – Ümañg ßürmån Nov 02 '18 at 09:45
You can finally try this: [GitHub Link](https://gist.github.com/dominicthomas/d9123f0f18fa05422e52755c30d9e2ba) @initialise I have upvoted your question for others to focus on it.. – Ümañg ßürmån Nov 02 '18 at 10:01
