项目中要到图片、视频选择的功能，然后google了一下，找到Matisse，知乎的图片选择框架，用的人还挺多的，果断依赖gradle,然后开始我的踩坑之旅。
首先，框架本身的图片框架glide是v3版本的，然后我项目中的是目前最新的v4.7.1,然后需要重写它的图片加载.imageEngine(new GlideEngine())，因为低版本的一些api在高版本已经找不到了，这都是小问题。
public class GlideEngine implements ImageEngine{
@Override
public void loadThumbnail(Context context, int resize, Drawable placeholder, ImageView imageView, Uri uri) {
Glide.with(context)
.asBitmap() // some .jpeg files are actually gif
.load(uri)
.apply(new RequestOptions()
.override(resize, resize)
.placeholder(placeholder)
.centerCrop())
.into(imageView);
}
@Override
public void loadGifThumbnail(Context context, int resize, Drawable placeholder, ImageView imageView,
Uri uri) {
Glide.with(context)
.asBitmap() // some .jpeg files are actually gif
.load(uri)
.apply(new RequestOptions()
.override(resize, resize)
.placeholder(placeholder)
.centerCrop())
.into(imageView);
}
@Override
public void loadImage(Context context, int resizeX, int resizeY, ImageView imageView, Uri uri) {
Glide.with(context)
.load(uri)
.apply(new RequestOptions()
.override(resizeX, resizeY)
.priority(Priority.HIGH)
.fitCenter())
.into(imageView);
}
@Override
public void loadGifImage(Context context, int resizeX, int resizeY, ImageView imageView, Uri uri) {
Glide.with(context)
.asGif()
.load(uri)
.apply(new RequestOptions()
.override(resizeX, resizeY)
.priority(Priority.HIGH)
.fitCenter())
.into(imageView);
}
@Override
public boolean supportAnimatedGif() {
return true;
}
}
然后运行成功，如愿以偿的打开了相册，当然这都建立了你已经申请并获得了6.0以上的运行期权限，Matisse图片加载器修改后，预览图片直接黑屏：
Glide: Root cause (1 of 5) java.lang.OutOfMemoryError: Failed to allocate a 19660812 byte allocation with 13530040 free bytes and 12MB until OOM
Glide: Root cause (4 of 5)
java.io.IOException: java.lang.RuntimeException: setDataSource failed: status = 0x80000000
然后我下载了一份github上的代码，发现了Demo和GitHub上示例代码的问题。
Matisse.from(SampleActivity.this)
.choose(MimeType.ofAll(), false)
.countable(true)
.capture(true)
.captureStrategy(
new CaptureStrategy(true, "com.zhihu.matisse.sample.fileprovider"))
.maxSelectable(9)
.addFilter(new GifSizeFilter(320, 320, 5 * Filter.K * Filter.K))
.gridExpectedSize(
getResources().getDimensionPixelSize(R.dimen.grid_expected_size))
.restrictOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT)
.thumbnailScale(0.85f)
// .imageEngine(new GlideEngine()) // for glide-V3
.imageEngine(new Glide4Engine()) // for glide-V4
.setOnSelectedListener(new OnSelectedListener() {
@Override
public void onSelected(
@NonNull List uriList, @NonNull List pathList) {
// DO SOMETHING IMMEDIATELY HERE
Log.e("onSelected", "onSelected: pathList=" + pathList);
}
})
.originalEnable(true)
.maxOriginalSize(10)
.setOnCheckedListener(new OnCheckedListener() {
@Override
public void onCheck(boolean isChecked) {
// DO SOMETHING IMMEDIATELY HERE
Log.e("isChecked", "onCheck: isChecked=" + isChecked);
}
})
.forResult(REQUEST_CODE_CHOOSE);
在.addFilter(new GifSizeFilter())中GifSizeFilter这个类居然不是public的，在按照github上的示例代码时这行代码报错了，当时我以为是不太重要的代码，然后去掉了。

@Override
public IncapableCause filter(Context context, Item item) {
if (!needFiltering(context, item))
return null;
Point size = PhotoMetadataUtils.getBitmapBound(context.getContentResolver(), item.getContentUri());
if (size.x < mMinWidth || size.y < mMinHeight || item.size > mMaxSize) {
return new IncapableCause(IncapableCause.DIALOG, context.getString(R.string.error_gif, mMinWidth,
String.valueOf(PhotoMetadataUtils.getSizeInMB(mMaxSize))));
}
return null;
}
}
最后的解决办法是复制了GifSizeFilter 并把它申明为public，问题解决。
