我有一个 Android 应用程序,我正在从图库中导入图像。它适用于所有图像,但对于某些大小超过 1.5 mb 的图像已更改其方向。我附上了该应用程序的图像。我正在使用此代码。
newImage=(ImageView)findViewById(R.id.newImage);
imagePath = getIntent().getStringExtra("ImagePath");
try {
ExifInterface exif = new ExifInterface(imagePath);
orientation = exif.getAttributeInt(ExifInterface.TAG_ORIENTATION, 1);
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
try{
BitmapFactory.Options options=new BitmapFactory.Options();
options.inJustDecodeBounds=true;
InputStream is=new FileInputStream(new File(imagePath) );
Display display = getWindowManager().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();
}
int scrWidth = point.x;
int scrHeight = point.y;
originalBitmap=BitmapFactory.decodeStream(is,null,options);
int imageWidth = options.outWidth;
int imageHeight = options.outHeight;
if(imageHeight>imageWidth){
int newWidth=(scrWidth/2);
int newHeight=(int)((float)imageHeight*((float)newWidth/(float)imageWidth));
originalBitmap=BitmapLoader.loadBitmap(imagePath, newWidth, newHeight);
}else{
int newWidth=(scrWidth/2);
//int newHeight=imageHeight*(imageWidth/newWidth);
int newHeight=(int)((float)imageHeight*((float)imageWidth/(float)newWidth));
originalBitmap=BitmapLoader.loadBitmap(imagePath, newWidth, newHeight);
}
is.close();
//originalBitmap= Bitmap.createBitmap(originalBitmap, 0, 0, originalBitmap.getWidth(), originalBitmap.getHeight(), matrix, true);
newBitmap=originalBitmap;
options.inJustDecodeBounds=true;
temp=BitmapLoader.loadBitmap(imagePath, 1200, 1200);
}
catch (Exception e) {
// TODO: handle exception
}
if(originalBitmap!=null)
//originalImage.setImageBitmap(originalBitmap);
if(newBitmap!=null)
newImage.setImageBitmap(newBitmap);
}
