我使用Glide库（带编译SDK 26的v4.2.0）和christbanes Photoview库面临一个奇怪的事情。我能够加载，显示一些图像（大小<300 Kb）并能够使用Photoview库执行缩放手势，但不能在所有图像上执行。虽然图像存在于位置/存储/模拟/ 0 / hhp_images /但仍然Glide加载一些图像并显示其他人的错误。

它无法加载的图像大小是可变的，即在大小写的情况下，它是150 Kb或大约300 Kb。所以我认为这不是因为大尺寸。但我无法弄清楚问题所在。
这是在PopupWindow中调用滑动和加载图像的类的代码 -
public class PhotoFullPopupWindow extends PopupWindow {
View view;
Context mContext;
PhotoView photoView;
ProgressBar loading;
ViewGroup parent;
private static PhotoFullPopupWindow instance = null;
public PhotoFullPopupWindow(Context ctx, int layout, View v, String imageUrl, Bitmap bitmap) {
super(((LayoutInflater) ctx.getSystemService(LAYOUT_INFLATER_SERVICE)).inflate( R.layout.popup_photo_full, null)
, ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.MATCH_PARENT);
if (Build.VERSION.SDK_INT >= 21) {
setElevation(5.0f);
}
// setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
this.mContext = ctx;
this.view = getContentView();
ImageButton closeButton = (ImageButton) this.view.findViewById(R.id.ib_close);
setOutsideTouchable(true);
setFocusable(true);
// Set a click listener for the popup window close button
closeButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
// Dismiss the popup window
dismiss();
}
});
//---------Begin customising this popup--------------------
photoView = (PhotoView) view.findViewById(R.id.image);
// loading = (ProgressBar) view.findViewById(R.id.loading);
photoView.setMaximumScale(6);
parent = (ViewGroup) photoView.getParent();
// ImageUtils.setZoomable(imageView);
//----------------------------
if (bitmap != null) {
// loading.setVisibility(View.GONE);
if (Build.VERSION.SDK_INT >= 16) {
parent.setBackground(new BitmapDrawable(mContext.getResources(), Constants.fastblur(Bitmap.createScaledBitmap(bitmap, 50, 50, true))));// ));
} else {
onPalette(Palette.from(bitmap).generate());
}
photoView.setImageBitmap(bitmap);
} else {
// loading.setIndeterminate(true);
// loading.setVisibility(View.VISIBLE);
GlideApp.with(ctx) .asBitmap()
.load(Uri.fromFile(new File(imageUrl)))
// .override(600, 200)
.error(R.drawable.sample_image)
.listener(new RequestListener<Bitmap>() {
@Override
public boolean onLoadFailed(@Nullable GlideException e, Object model, Target<Bitmap> target, boolean isFirstResource) {
// loading.setIndeterminate(false);
// loading.setBackgroundColor(Color.LTGRAY);
Toast.makeText(mContext, "Error: Unable to open image", Toast.LENGTH_SHORT).show();
// dismiss();
return false;
}
@Override
public boolean onResourceReady(Bitmap resource, Object model, Target<Bitmap> target, DataSource dataSource, boolean isFirstResource) {
if (Build.VERSION.SDK_INT >= 16) {
// parent.setBackground(new BitmapDrawable(mContext.getResources(), Constants.fastblur(Bitmap.createScaledBitmap(resource, 50, 50, true))));// ));
parent.setBackgroundColor(Color.BLACK);
} else {
onPalette(Palette.from(resource).generate());
}
photoView.setImageBitmap(resource);
// loading.setVisibility(View.GONE);
return false;
}
})
.diskCacheStrategy(DiskCacheStrategy.ALL)
.into(photoView);
showAtLocation(v, Gravity.CENTER, 0, 0);
}
//------------------------------
}
public void onPalette(Palette palette) {
if (null != palette) {
ViewGroup parent = (ViewGroup) photoView.getParent().getParent();
parent.setBackgroundColor(palette.getDarkVibrantColor(Color.GRAY));
}
}
}
我尝试在普通的ImageView 200dp * 200dp而不是Photoview中加载图像，但仍然遇到同样的错误。
已解决 - 实际上代码没有任何问题。设备存在问题 - Moto G4 Plus。当我在其他模拟器上运行应用程序时，它运行成功。

因为当应用Android版本为6.0时，您必须要求运行时权限READ_EXTERNAL_STORAGE。
你可以这样做
/**
* permission code
*/
private static final int MY_PERMISSIONS_REQUEST_READ_EXTERNAL_STORAGE = 1;
/**
* requestPermissions and do something
*
*/
public void requestRead() {
if (ContextCompat.checkSelfPermission(this,
Manifest.permission.READ_EXTERNAL_STORAGE)
!= PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.READ_EXTERNAL_STORAGE},
MY_PERMISSIONS_REQUEST_READ_EXTERNAL_STORAGE);
} else {
readFile();
}
}
/**
* do you want to do
*/
public void readFile() {
// do something
}
/**
* onRequestPermissionsResult
*
* @param requestCode
* @param permissions
* @param grantResults
*/
@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
if (requestCode == MY_PERMISSIONS_REQUEST_READ_EXTERNAL_STORAGE) {
if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
readFile();
} else {
// Permission Denied
Toast.makeText(ToolbarActivity.this, "Permission Denied", Toast.LENGTH_SHORT).show();
}
return;
}
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
}

就我而言，我的网址中没有https://（例如，www.google.ru/images/branding/googlelogo/1x/googlelogo_color_272x92dp.png）。
我从日志中看到了：
I / Glide：根本原因（第1个，共3个） java.io.FileNotFoundException：/example.com/static/img/brands/hyundai.png（没有此类文件或目录）
