}
}
ImageAdapter
public class ImageAdapter extends BaseAdapter implements SpinnerAdapter {

public ImageAdapter(Context context) {
// TODO Auto-generated constructor stub
this.context = context;

imageView.setImageResource(ThumbsIds[position]);
return imageView;
}
public static Integer[] ThumbsIds={
R.drawable.abs_icla,
R.drawable.abs_dog,
R.drawable.abs_flow,
R.drawable.abs_neb,

};
}
FullScreenImage
public class FullScreenImage extends Activity {
protected void onCreate(Bundle savedInstanceState) {
setContentView(R.layout.full_image);
Intent intent = getIntent();
long imageId = (Long) intent.getExtras().get(FullScreenImage.class.getName());
ImageView imageView = (ImageView) findViewById(R.id.fullImage);
imageView.setLayoutParams( new ViewGroup.LayoutParams(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.MATCH_PARENT));
imageView.setImageResource((int) imageId);
imageView.setScaleType(ImageView.ScaleType.FIT_XY);
}
}

clean you project if it does not work
imageView.setLayoutParams( new ViewGroup.LayoutParams(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.MATCH_PARENT));
change it to
imageView.setLayoutParams( new LinearLayout.LayoutParams(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.MATCH_PARENT));

Android Gallery option for setting wallpaper

This is the project code which is gallery including 4 pictures. I set an option menu which will set picture as a wallpaper. I try to run it works but when i select the "Set as Wallpaper"(menuSet) it is forced to close.
private ImageView foto;
private Gallery gallery;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_naruto_hd_wallpapers);
gallery = (Gallery) findViewById(R.id.gallery);
foto = (ImageView) findViewById(R.id.imageView1);
gallery.setAdapter(new ImageAdapter(this));
gallery.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView parent, View v, int position, long id) {
switch(position) {
case 0: foto.setImageResource(R.drawable.ornek1); break;
case 1: foto.setImageResource(R.drawable.ornek2); break;
case 2: foto.setImageResource(R.drawable.ornek3); break;
case 3: foto.setImageResource(R.drawable.ornek4); break;
}
}
});
}
public class ImageAdapter extends BaseAdapter {
int mGalleryItemBackground;
private Context mContext;
private Integer[] mImageIds = {
R.drawable.ornek1,
R.drawable.ornek2,
R.drawable.ornek3,
R.drawable.ornek4,
};
public ImageAdapter(Context c) {
mContext = c;
TypedArray attr = mContext.obtainStyledAttributes(R.styleable.GaleriOlusturma);
mGalleryItemBackground = attr.getResourceId(
R.styleable.GaleriOlusturma_android_galleryItemBackground, 0);
attr.recycle();
}
public int getCount() {
return mImageIds.length;
}
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
ImageView imageView = new ImageView(mContext);
imageView.setImageResource(mImageIds[position]);
imageView.setLayoutParams(new Gallery.LayoutParams(150, 100));
imageView.setScaleType(ImageView.ScaleType.FIT_XY);
imageView.setBackgroundResource(mGalleryItemBackground);
return imageView;
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// TODO Auto-generated method stub
switch (item.getItemId()) {
case R.id.menuSet:
Bitmap mBitmap = BitmapFactory.decodeResource(getResources(),R.drawable.ornek1);
WallpaperManager myWallpaperManager = WallpaperManager.getInstance(getApplicationContext());
try {
myWallpaperManager.setBitmap(mBitmap);
Toast.makeText(NarutoHdWallpapers.this, "Wallpaper set", Toast.LENGTH_SHORT).show();
} catch (IOException e) {
Toast.makeText(NarutoHdWallpapers.this, "Error setting wallpaper", Toast.LENGTH_SHORT).show();
}
return true;
default:
return super.onOptionsItemSelected(item);
}
}
}
If i change these blocks into a simple toast message it works fine.
Bitmap mBitmap = BitmapFactory.decodeResource(getResources(),R.drawable.ornek1);
WallpaperManager myWallpaperManager = WallpaperManager.getInstance(getApplicationContext());
try {
myWallpaperManager.setBitmap(mBitmap);
Toast.makeText(NarutoHdWallpapers.this, "Wallpaper set", Toast.LENGTH_SHORT).show();
} catch (IOException e) {
Toast.makeText(NarutoHdWallpapers.this, "Error setting wallpaper", Toast.LENGTH_SHORT).show();
}
**Note : I put the permission into a manifest

Creating Image Gallery using Drawable images in res folder

I am new to android. I have a requirement now. I need to add around 10 images in the res/drawable folder and on running the app i should display this images on a listView.and on selecting any of the image i should display this image in the new activity should be able to zoom in and zoom out. Please help me out to figure out this with the sample code.
Thanks in advance.

this example for create Gallery, select one and set to selectedImageView.
so after that you can do everything with selectedImageView.
public class MyActivity extends Activity{
private int selectedImagePosition = 0;
private ImageView selectedImageView;
private List<Drawable> drawables;
private Gallery gallery;
#Override
public void onCreate(Bundle savedInstanceState) {
selectedImageView = (ImageView) view.findViewById(R.id.selected_imageview);
getDrawablesList();
gallery = (Gallery) view.findViewById(R.id.Gallery);
gallery.setAdapter(new ImageAdapter(getActivity().getApplicationContext()));
gallery.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View v, final int position, long id) {
setSelectedImage(selectedImagePosition);
}
});
private void getDrawablesList() {
drawables = new ArrayList<Drawable>();
drawables.add(getResources().getDrawable(R.drawable.res1));
drawables.add(getResources().getDrawable(R.drawable.res2));
drawables.add(getResources().getDrawable(R.drawable.res3));
drawables.add(getResources().getDrawable(R.drawable.res4));
}
private void setSelectedImage(int selectedImagePosition) {
BitmapDrawable bd = (BitmapDrawable) drawables.get(selectedImagePosition);
Bitmap b = Bitmap.createScaledBitmap(bd.getBitmap(), (int) (bd.getIntrinsicHeight() * 0.9), (int) (bd.getIntrinsicWidth() * 0.7), false);
selectedImageView.setImageBitmap(b);
selectedImageView.setScaleType(ScaleType.FIT_XY);
}

You can use a GalleryView
Refer to the link below for more help:

private ImageView selectedImageView;
private TextView _nameTextView;
private Gallery gallery;
Integer[] imageIDs = { R.drawable.hbath, R.drawable.hfood,
R.drawable.hmedicine, R.drawable.htherapy, R.drawable.htoilet,
R.drawable.hother };
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
selectedImageView = (ImageView) findViewById(R.id.imageSwitcher1);
_nameTextView = (TextView) findViewById(R.id.NameTextView);
gallery = (Gallery) findViewById(R.id.gallery1);
gallery.setAdapter(new ImageAdapter(this));
gallery.setOnItemClickListener(new OnItemClickListener() {
gallery.setOnItemSelectedListener(new OnItemSelectedListener() {
public void onItemSelected(AdapterView<?> arg0, View arg1,
int position, long arg3) {
// TODO Auto-generated method stub
if (position == 0) {
selectedImageView
.setImageResource(R.drawable.hbathbackground);
_nameTextView.setText("Toilet");
} else if (position == 1) {
selectedImageView
.setImageResource(R.drawable.hfoodbackground);
_nameTextView.setText("Food");
} else if (position == 2) {
selectedImageView
.setImageResource(R.drawable.hmedicinebackground);
_nameTextView.setText("Medicine");
} else if (position == 3) {
selectedImageView
.setImageResource(R.drawable.htherapybackground);
_nameTextView.setText("Therapy");
} else if (position == 4) {
selectedImageView
.setImageResource(R.drawable.htoiletbackground);
_nameTextView.setText("Bath");
} else if (position == 5) {
selectedImageView
.setImageResource(R.drawable.hotherbackground);
_nameTextView.setText("Other");
}
}
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});
}
and ImageAdapter
public class ImageAdapter extends BaseAdapter {
private Context context;
private int itemBackground;
public ImageAdapter(Context c) {
context = c;
// ---setting the style---
TypedArray a = obtainStyledAttributes(R.styleable.Gallery1);
itemBackground = a.getResourceId(
R.styleable.Gallery1_android_galleryItemBackground, 0);
a.recycle();
}
// ---returns the number of images---
public int getCount() {
return imageIDs.length;
}
// ---returns the ID of an item---
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
// ---returns an ImageView view---
public View getView(int position, View convertView, ViewGroup parent) {
ImageView imageView = new ImageView(context);
imageView.setImageResource(imageIDs[position]);
imageView.setBackgroundColor(0xFF000000);
// imgView.setImageBitmap(bitmap);
imageView.setScaleType(ImageView.ScaleType.FIT_XY);
imageView.setLayoutParams(new Gallery.LayoutParams(155, 235));
imageView.setBackgroundResource(R.drawable.customborder2);
return imageView;
}
}

I have the above code for a wallpaper app. The activity xml layout file contains a gallery view and a imageswitcher below it in which the user can browse and navigate through the gallery and the corresponding image opens up below in the imageswitcher. User can then set the image as a wallpaper or save to sd card. The above code works perfectly for small images, but fails miserably for large images like the one I intend to have in the app. The app crashes when it runs out of memory(openglrenderer is out of memory). How do I fix this? Pls help me, Ive spent many a hour on this problem.
Thanks

The error is that i cant use imageView.setImageResource(imageIDs[position]); for strings...ant hepl please?

You need to decode the image from the link for example,
URL url = new URL("load your URL");
Bitmap bmp = BitmapFactory.decodeStream(url.openConnection().getInputStream());
img_downloaded.setImageBitmap(bmp);
Update:
I modified your code, you may try with this,
public class MainActivity extends Activity {
private String[] imageIDs = {
"http://lh5.ggpht.com/_mrb7w4gF8Ds/TCpetKSqM1I/AAAAAAAAD2c/Qef6Gsqf12Y/s144-c/_DSC4374%20copy.jpg",
