Load Images From Phone in Android
Sample Code
private Bitmap getBitmap(String imageFilePath)
{
// Load up the image's dimensions not the image itself
BitmapFactory.Options bmpFactoryOptions = new BitmapFactory.Options();
bmpFactoryOptions.inJustDecodeBounds = true;
Bitmap bmp = BitmapFactory.decodeFile(imageFilePath, bmpFactoryOptions);
int heightRatio = (int) Math.ceil(bmpFactoryOptions.outHeight/ (float) DISPLAYHEIGHT);
int widthRatio = (int) Math.ceil(bmpFactoryOptions.outWidth/ (float) DISPLAYWIDTH);
Log.v("HEIGHTRATIO", "" + heightRatio);
Log.v("WIDTHRATIO", "" + widthRatio);
// If both of the ratios are greater than 1, one of the sides of
// the image is greater than the screen
if (heightRatio > 1 && widthRatio > 1) {
if (heightRatio > widthRatio) {
// Height ratio is larger, scale according to it
bmpFactoryOptions.inSampleSize = heightRatio;
} else {
// Width ratio is larger, scale according to it
bmpFactoryOptions.inSampleSize = widthRatio;
}
}
// Decode it for real
bmpFactoryOptions.inJustDecodeBounds = false;
bmp = BitmapFactory.decodeFile(imageFilePath, bmpFactoryOptions);
return bmp;
}
