I spent hours on an issue that doesn't seem complicated, but despite all the existing messages on this topic, I still don't find a solution...
I'm using a viewpager and in the adapter I have a button and a imageview. I want to set the picture from the imageview as wallpaper when the button is clicked by using myWallpaperManager.setBitmap(image). Before that I resize the picture to fit in screen size. The wallpaper is changed but the picture stays zoomed and cropped. I would like to set the wallpaper with the whole picture. I have the same values for width and height of getDefaultDisplay() and width and height of myWallpaperManager.getDesiredMinimumHeight/Width().
I tried many different ways that didn't work. I don't know what else to do ! Thanks for a lot for your answer.
Here is the code :
Button ButWallpaper = (Button) viewLayout.findViewById(R.id.ButWallpaper);
ButWallpaper.setOnClickListener(new Button.OnClickListener(){
@Override
public void onClick(View arg0) {
Bitmap image;
Bitmap imagelarge = ((BitmapDrawable)imageView2.getDrawable()).getBitmap();
int Measuredwidth = 0;
int Measuredheight = 0;
Point size = new Point();
WindowManager w = _activity.getWindowManager();
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
w.getDefaultDisplay().getSize(size);
Measuredwidth = size.x;
Measuredheight = size.y;
}else{
Display d = w.getDefaultDisplay();
Measuredwidth = d.getWidth();
Measuredheight = d.getHeight();
}
Log.i("TAG", String.valueOf(Measuredwidth));
Log.i("TAG", String.valueOf(Measuredheight));
image = Bitmap.createScaledBitmap(imagelarge, Measuredwidth, Measuredheight,true);
// TODO Auto-generated method stub
WallpaperManager myWallpaperManager
= WallpaperManager.getInstance(_activity.getApplicationContext());
try {
myWallpaperManager.setBitmap(image);
myWallpaperManager.suggestDesiredDimensions(Measuredwidth, Measuredheight);
Log.i("TAG", String.valueOf(myWallpaperManager.getDesiredMinimumHeight()));
Log.i("TAG", String.valueOf(myWallpaperManager.getDesiredMinimumWidth()));
Toast.makeText(_activity.getApplicationContext(), "Wallpaper changed", toast.LENGTH_LONG).show();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}});
See if this helps:
DisplayMetrics metrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(metrics);
int height = metrics.heightPixels;
int width = metrics.widthPixels;
Bitmap bitmap = Bitmap.createScaledBitmap(yourimagebitmap, width, height, true);
WallpaperManager.getInstance(MyActivity.this).setBitmap(bitmap);
