I am attempting to use Picasso to get three Bitmap
images from a URL
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.tab2);
Drawable d1 = new BitmapDrawable(Picasso.with(Tab2.this).load(zestimateImg1).get());
}
I am getting FATAL EXCEPTION
with this code. I suspect it has to do with the fact that this should be done within AsyncTask
, but I can't get it to work. If using that is avoidable, I would like to do this without using AsyncTask
.
How can I get this code to run without crashing?
If the best way to do this is with AsyncTask
, then that solution is ok.
You cannot make synchronous requests in the main thread. If you dont want to use an AsyncThread then just use Picasso together with a Target.
Picasso.with(Tab2.this).load(zestimateImg1).into(new Target(...);
I recommend you save a reference to your target like so:
Target mTarget =new Target (...);
This is because Picasso uses weak references to them and they might be garbage collected before the process is finished.
None of above worked for me instead this
Handler uiHandler = new Handler(Looper.getMainLooper());
uiHandler.post(new Runnable(){
@Override
public void run() {
Picasso.with(Context)
.load(imageUrl)
.into(imageView);
}
});
Hope it may be useful for someone
Just for the record:
Picasso.with(context).load(url).into(new Target() {
@Override
public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from) {
Log.i(TAG, "The image was obtained correctly");
}
@Override
public void onBitmapFailed(Drawable errorDrawable) {
Log.e(TAG, "The image was not obtained");
}
@Override
public void onPrepareLoad(Drawable placeHolderDrawable) {
Log.(TAG, "Getting ready to get the image");
//Here you should place a loading gif in the ImageView
//while image is being obtained.
}
});
Source: http://square.github.io/picasso/
onPrepareLoad()
is called always after starting the request.
from
can be "DISK", "MEMORY" or "NETWORK" to indicate where was the image obtained from.
