I Bild mit picasa api geladen hatte, aber Problem ist, ich nicht in der Lage bin volles Bild zu setzen, wie Bild Scroll Lage ist, hier ist der Code, den ich verwende, soSets Tapeten passen zu screenen
public class Utils {
private String TAG = Utils.class.getSimpleName();
private Context _context;
private PrefManager pref;
// constructor
public Utils(Context context) {
this._context = context;
pref = new PrefManager(_context);
}
/*
* getting screen width
*/
@SuppressWarnings("deprecation")
public int getScreenWidth() {
int columnWidth;
WindowManager wm = (WindowManager) _context
.getSystemService(Context.WINDOW_SERVICE);
Display display = wm.getDefaultDisplay();
final Point point = new Point();
try {
display.getSize(point);
} catch (java.lang.NoSuchMethodError ignore) {
// Older device
point.x = display.getWidth();
point.y = display.getHeight();
}
columnWidth = point.x;
return columnWidth;
}
public void saveImageToSDCard(Bitmap bitmap) {
File myDir = new File(
Environment
.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES),
pref.getGalleryName());
myDir.mkdirs();
Random generator = new Random();
int n = 10000;
n = generator.nextInt(n);
String fname = "Wallpaper-" + n + ".jpg";
File file = new File(myDir, fname);
if (file.exists())
file.delete();
try {
FileOutputStream out = new FileOutputStream(file);
bitmap.compress(Bitmap.CompressFormat.JPEG, 90, out);
out.flush();
out.close();
Toast.makeText(
_context,
_context.getString(R.string.toast_saved).replace("#",
"\"" + pref.getGalleryName() + "\""),
Toast.LENGTH_SHORT).show();
Log.d(TAG, "Wallpaper saved to: " + file.getAbsolutePath());
} catch (Exception e) {
e.printStackTrace();
Toast.makeText(_context,
_context.getString(R.string.toast_saved_failed),
Toast.LENGTH_SHORT).show();
}
}
public void setAsWallpaper(Bitmap bitmap) {
WallpaperManager wallpaperManager = WallpaperManager.getInstance(_context);
try {
int widht=Resources.getSystem().getDisplayMetrics().widthPixels;
int height=Resources.getSystem().getDisplayMetrics().heightPixels;
wallpaperManager.suggestDesiredDimensions(widht, height);
wallpaperManager.setBitmap(bitmap);
} catch (IOException e) {
e.printStackTrace();
}}
}
Wo ich gehe falsch ............................................... ...
