我试图缩放位图使其适合，因为某些设备不会显示大于2048的图像。
我找到了解决方案，但选择/拍照后应用程序崩溃。
这段代码：（在onActivityResult内部）
currImageURI = data.getData();
path=(getRealPathFromURI(currImageURI));
Drawable d = Drawable.createFromPath(path);
image.setVisibility(View.VISIBLE);
mPhoto=drawableToBitmap(d);
Bitmap sized = mPhoto;
if(mPhoto.getHeight()>=2048||mPhoto.getWidth()>=2048){
sized = Bitmap.createScaledBitmap(mPhoto, (int)(mPhoto.getWidth()*0.8), (int)(mPhoto.getHeight()*0.8), false);
}
image.setImageBitmap(sized);
LogCat：

149行是：
sized = Bitmap.createScaledBitmap(mPhoto, (int)(mPhoto.getWidth()*0.8), (int)(mPhoto.getHeight()*0.8), false);
您能告诉我如何防止它崩溃吗？
谢谢！
更新：
应用仍然崩溃：

码：
currImageURI = data.getData();
path=(getRealPathFromURI(currImageURI));
Drawable d = Drawable.createFromPath(path);
image.setVisibility(View.VISIBLE);
mPhoto=drawableToBitmap(d);
Bitmap sized = mPhoto;
if(mPhoto.getHeight()>=2048||mPhoto.getWidth()>=2048){
sized=getResizedBitmap(mPhoto,(int)(mPhoto.getHeight()*0.8),(int)(mPhoto.getWidth()*0.8));
}
image.setImageBitmap(sized);
最佳答案
请看看我的相关问题：
High resolution Image - OutOfMemoryError
我建议您将图像放入Drawables文件夹。从那里，使用下面的代码以适当的大小加载它。这将减少应用程序的内存使用量，并且始终仅使用所需的内存量。
确保内存中只有一个实例。显示它之后，调用recycle()并将您的引用设置为null。
这样可以加载图像：
public Bitmap scaleDownBitmap(Bitmap photo, int newHeight) {
final float densityMultiplier = getResources().getDisplayMetrics().density;
int h= (int) (newHeight*densityMultiplier);
int w= (int) (h * photo.getWidth()/((double) photo.getHeight()));
photo = Bitmap.createScaledBitmap(photo, w, h, true);
return photo;
}
像这样使用它：
ImageView.setImageBitmap(scaleDownBitmap(youroldbitmap, 300));
注意不要为newHeight使用太高的值，并要记住densityMultiplier。
