Set an item long click listener in GridView

Question

I want to add an item long click listener, which will set the image selected as wallpaper. I am getting images from web and displaying them in a grid view. My grid activity is shown below. I already have an on click listener to show a full screen image.

public class ImageGridActivity extends BaseActivity {

String[] imageUrls;

DisplayImageOptions options;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    requestWindowFeature(Window.FEATURE_NO_TITLE);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN);

    setContentView(R.layout.ac_image_grid);

    Bundle bundle = getIntent().getExtras();
    imageUrls = bundle.getStringArray(Extra.IMAGES);

    options = new DisplayImageOptions.Builder()
            .showStubImage(R.drawable.stub_image)
            .showImageForEmptyUri(R.drawable.image_for_empty_url)
            .cacheInMemory().cacheOnDisc()
            .bitmapConfig(Bitmap.Config.RGB_565).build();

    GridView gridView = (GridView) findViewById(R.id.gridview);
    gridView.setAdapter(new ImageAdapter());

    // Set Long-Clickable
    gridView.setLongClickable(true);
    gridView.setOnItemLongClickListener(new OnItemLongClickListener() {

        @SuppressLint("NewApi")
        public boolean onItemLongClick(AdapterView<?> parent, View arg1,
                int position, long arg3) {
            // TODO Auto-generated method stub
            ImageAdapter i = (ImageAdapter) parent.getAdapter();
            Bitmap mBitmap = BitmapFactory.decodeResource(getResources(),
                    (int) i.getItemId(position));

            // Get the WallpaperManager
            WallpaperManager myWallpaperManager = WallpaperManager
                    .getInstance(getApplicationContext());

            try {
                // Set the clicked bitmap
                myWallpaperManager.setBitmap(mBitmap);
                Toast.makeText(ImageGridActivity.this, "Wallpaper set",
                        Toast.LENGTH_SHORT).show();
            } catch (IOException e) {
                Toast.makeText(ImageGridActivity.this, "Error setting wallpaper",
                        Toast.LENGTH_SHORT).show();
            }

            return false;
        }
    });

    gridView.setOnItemClickListener(new OnItemClickListener() {

        @SuppressLint("NewApi")
        @Override
        public void onItemClick(AdapterView<?> parent, View view,
                int position, long id) {
            startImageGalleryActivity(position);
        }
    });

    gridView.setOnScrollListener(new PauseOnScrollListener(true, true));

}

private void startImageGalleryActivity(int position) {
    Intent intent = new Intent(this, ImagePagerActivity.class);
    intent.putExtra(Extra.IMAGES, imageUrls);
    intent.putExtra(Extra.IMAGE_POSITION, position);
    startActivity(intent);
}

public class ImageAdapter extends BaseAdapter {
    @Override
    public int getCount() {
        return imageUrls.length;
    }

    @Override
    public Object getItem(int position) {
        return null;
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        final ImageView imageView;
        if (convertView == null) {
            imageView = (ImageView) getLayoutInflater().inflate(
                    R.layout.item_grid_image, parent, false);
        } else {
            imageView = (ImageView) convertView;
        }

        imageLoader.displayImage(imageUrls[position], imageView, options);
        return imageView;
    }
}

Use OnItemLong listener instead OnItemClick Listener.

Instead of:

gridView.setOnItemClickListener(new OnItemClickListener() {
        @SuppressLint("NewApi")
        @Override
        public void onItemClick(AdapterView<?> parent, View view,
                int position, long id) {

            startImageGalleryActivity(position);
        }
    });

Use

 gridView.setOnItemLongClickListener(new OnItemLongClickListener() {

    @Override
    public boolean onItemLongClick(AdapterView<?> arg0, View arg1,
            int position, long arg3) {
       startImageGalleryActivity(position);
        return false;
    }
});

Updated

OnItemClickListener

 gridview.setOnItemClickListener(new OnItemClickListener() {
              public void onItemClick(AdapterView<?> parent, View v, int position, long id) { 
                  Toast.makeText(test2.this, "Click Listener", Toast.LENGTH_SHORT).show(); 
                   // open the pager activity
                  }    });

OnItemLongClickListener

gridview.setOnItemLongClickListener(new OnItemLongClickListener() {

                    public boolean onItemLongClick(AdapterView<?> arg0, View arg1,
                            int position, long arg3) {
                        Toast.makeText(test2.this, "LONG PRESS", Toast.LENGTH_SHORT).show();
                        //set the image as wallpaper 
                        return true;
                    }
                });

i want both item click listner which will open the pager activity..and also the onItemLongClickListner which will set the image as wallpaper — Abhay Sood, Jan 21 '13 at 17:48

Use this instead :

    gridView.setOnItemLongClickListener(new OnItemLongClickListener() {

        @Override
        public boolean onItemLongClick(AdapterView<?> arg0, View arg1,
                int arg2, long arg3) {
            // TODO Auto-generated method stub
            return false;
        }
    });

Write This part in your code to set long Click on gridview

    GridView  gridView =  (GridView) findViewById(R.id.gridview);
    //Set Long-Clickable
    gridView.setLongClickable(true);
    gridView.setOnItemLongClickListener(new OnItemLongClickListener() {

        @Override
        public boolean onItemLongClick(AdapterView<?> arg0, View view,
                int position , long id) {
            // TODO Auto-generated method stub
                       Toast.makeText(getApplicationContext(), "Long Click", Toast.LENGTH_SHORT).show();
                            /*
                             *You Can use parameters like position,view or id to
                             *Customize your action
                             */   
            return false;
        }
    });

Click Listener

gridView.setOnItemClickListener(new OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View v,
                int position, long id) {
    Toast.makeText(getApplicationContext(), "Click", Toast.LENGTH_SHORT).show();
        }
    });

To Set Wall Paper i think it need to set permission

   <uses-permission android:name="android.permission.SET_WALLPAPER"></uses-permission>

Note : look at log cat its saying Resources$NotFoundException check you had added resources correctly. may be on wrong folder or something check this

i want both item click listner which will open the pager activity..and also the onItemLongClickListner which will set the image as wallpaper...it does not perform long click method...but only the on click method — Abhay Sood, Jan 21 '13 at 17:53

First of all,change this line.

public class ImageGridActivity extends BaseActivity implements OnItemLongClickListener

Then add this code in your activity ...

 GridView gridView = (GridView) findViewById(R.id.gridview);
 gridView.setOnItemLongClickListener(this);

    @Override
    public boolean onItemLongClick(AdapterView<?> parent, View v, int pos,long id) 
    {
        System.out.println("~~~~~~Long Item Clicked");
        return false;
    }

Hope this helps :)

Try this. Return true in onItemLongClick and your onItemClickListener is not called :)

public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) { 
.
.
.
return true;
}

You can use

gridView.setOnLongClickListener(new OnLongClickListener() {

                @Override
                public boolean onLongClick(View v) {
                    // TODO Auto-generated method stub
                    return false;
                }
            });
