I'm using Picasso library in my current project http://square.github.io/picasso/ . Everything is working fine but I just can't figure out how to implement Pinch Zoom for all images that are being loaded from URL. To be honest I don't even know where to place the onClickListener
.
My application have several fragments and each of them have 2 Tabs
, first Tab
has a ListView
and the second tab
has some pictures displayed in a GridView
:
Bmw.java
public class Bmw2 extends Fragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(com.zenyt.R.layout.bmw2, container, false);
GridView gv = (GridView) rootView.findViewById(R.id.grid_view);
gv.setAdapter(new com.zenyt.SampleGridViewAdapter(getActivity()));
gv.setOnScrollListener(new SampleScrollListener(getActivity()));
return rootView;
}
SampleGridViewAdapter
public final class SampleGridViewAdapter extends BaseAdapter {
private final Context context;
private final List<String> urls = new ArrayList<String>();
public SampleGridViewAdapter(Context context) {
this.context = context;
// Ensure we get a different ordering of images on each run.
Collections.addAll(urls, Data.URLS);
Collections.shuffle(urls);
}
@Override public View getView(int position, View convertView, ViewGroup parent) {
SquaredImageView view = (SquaredImageView) convertView;
if (view == null) {
view = new SquaredImageView(context);
view.setScaleType(CENTER_CROP);
}
// Get the image URL for the current position.
String url = getItem(position);
// Trigger the download of the URL asynchronously into the image view.
Picasso.with(context) //
.load(url) //
.placeholder(R.drawable.placeholder) //
.error(R.drawable.error) //
.fit() //
.tag(context) //
.into(view);
return view;
}
@Override public int getCount() {
return urls.size();
}
@Override public String getItem(int position) {
return urls.get(position);
}
@Override public long getItemId(int position) {
return position;
}
}
Data.java
final class Data {
static final String BASE = "http://www.hdcarwallpapers.com/walls/";
static final String BASE2 = "http://www3.cellsea.com//content/wallpaper/";
static final String EXT = ".jpg";
static final String[] URLS = {
BASE + "prior_design_audi_r8_gt850-wide" + EXT,
BASE + "2015_audi_rs6_avant_exclusive-wide" + EXT,
BASE + "2015_audi_tt_coupe_quattro-wide" + EXT,
BASE + "2015_audi_tt_coupe_quattro-wide" + EXT,
BASE + "2014_audi_prologue_concept_4-wide" + EXT,
BASE2 + "2010/WP4ce483c6efa9d" + EXT,
};
private Data() {
// No instances.
}
}
Sorry for my english.
Picasso library is used only to load the images from network.
You need to address your request with other library such as PhotoView or any other that support actions on images.
PhotoViewAttacher photoViewAttacher;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ImageView imageView = (ImageView) findViewById(R.id.imageView);
Picasso.with(this)
.load("http://easyway-ev.xyz/images/1.png")
.into(imageView);//Regular
photoViewAttacher = new PhotoViewAttacher(imageView);}
this is my answer, I take Picasso, and after i used photoView, also this video how sync photoView enter link description here I hope this help you!
