I have four images in the Gallery View. When we do swipe from left to right or right to left the Gallery View moves all the images i.e if I swipe from left to right from the first image then it will move to all the four images. What I want is that when I swipe it should only move to the next image. Can someone let me know how is this possible in galleryview?

I think you have to work with gesture for change the images with finger swipe.For that below code may helpful for u.

import java.util.ArrayList;
import android.app.Activity;
import android.gesture.Gesture;
import android.gesture.GestureLibraries;
import android.gesture.GestureLibrary;
import android.gesture.GestureOverlayView;
import android.gesture.Prediction;
import android.gesture.GestureOverlayView.OnGesturePerformedListener;
import android.os.Bundle;
import android.widget.Toast;


public class GesturesActivity extends Activity implements OnGesturePerformedListener {
    private GestureLibrary mLibrary;



@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    mLibrary = GestureLibraries.fromRawResource(this, R.raw.spells);
    if (!mLibrary.load()) {
        finish();
    }

    GestureOverlayView gestures = (GestureOverlayView) findViewById(R.id.gestures);
    gestures.addOnGesturePerformedListener(this);
}

public void onGesturePerformed(GestureOverlayView overlay, Gesture gesture) {
    ArrayList<Prediction> predictions = mLibrary.recognize(gesture);

    // We want at least one prediction
    if (predictions.size() > 0) {
        Prediction prediction = predictions.get(0);
        // We want at least some confidence in the result
        if (prediction.score > 1.0) {
            // Show the spell
            Toast.makeText(this, prediction.name, Toast.LENGTH_SHORT).show();
        }
    }
}




}

You can consider using a ViewFlipper with Gestures on it, look at this example:

EDIT:

Oh, obviously you should implement the gesture detection, take at look at this question/answer

  • cant we control that in (XML File) – bamini May 18 '11 at 11:17
  • it's easier to use this approach imo, overriding the standard gallery behaviour could be tedious – BFil May 18 '11 at 11:53
  • i added back and next button in this activity if i press the left button and right corresponding image i need to show.i can get image name how to pass that in gallery adapter – bamini May 19 '11 at 06:06
  • are you using the gallery or the viewflipper? first case: just do -> pos = gallery.getSelectedItemPosition(); gallery.setSelection(pos+1); - second case -> viewFlipper.showNext(); – BFil May 19 '11 at 07:15
