我想使用滑行将图像加载到位图中,但会引发错误
java.lang.IllegalArgumentException:您必须在后台线程上调用此方法
在com.bumptech.glide.util.Util.assertBackgroundThread(Util.java:141)
在com.bumptech.glide.request.RequestFutureTarget.doGet(RequestFutureTarget.java:186)
在com.bumptech.glide.request.RequestFutureTarget.get(RequestFutureTarget.java:108)
在extend.BitmapLoader.loadBitmapFromFile_Glide(BitmapLoader.java:60)
这是我的代码:
_runnable_animation = new Runnable() {
@Override
public void run() {
bm = get_bitmap();
}
};
_handler_animation.postDelayed(_runnable_animation, _RUNNABLE_THREAD_DELAY);
这是我的get_bitmap()方法:
try {
return Glide.with(context)
.asBitmap()
.load(new File(path))
.submit(500, 500)
.get();
} catch (InterruptedException e) {
e.printStackTrace();
return null;
} catch (ExecutionException e) {
e.printStackTrace();
return null;
}
最佳答案
我正在使用以下方法获取位图
public static void loadBitmapFromServer(Context context, String url, final OnBitmapLoadedListener callback) {
try {
Glide.with(context).load(url)
.asBitmap()
.priority(Priority.IMMEDIATE)
.listener(new RequestListener<String, Bitmap>() {
@Override
public boolean onException(Exception e, String model, Target<Bitmap> target, boolean isFirstResource) {
return false;
}
@Override
public boolean onResourceReady(Bitmap resource, String model, Target<Bitmap> target, boolean isFromMemoryCache, boolean isFirstResource) {
// you can do whatever you want to do with Bitamp
callback.onBitmapLoaded(resource);
return false;
}
});
} catch (Exception e) {}
}
声明界面如
public interface OnBitmapLoadedListener {
void onBitmapLoaded(Bitmap resource);
}
