当时的毕加索版本不支持我想要的版本,所以我使用了滑行3 。这是我设法整理的。
我还没有测试它,我从历史中整理了一下,因为我从我的应用程序中删除了此支持,这太过分了;
The version of Picasso at the time didn't support what I wanted so I went to use Glide 3. Here's what I managed to put together. I didn't test it yet, I pieced it together from history, because I removed this support from my app, it was an overkill; however it was working when the functionality was still present.
在 ConnectionCallbacks.onConnected
中:
Glide.get(getContext()).register(DriveId.class, InputStream.class, new DriveIdModelLoader.Factory(mClient));
在 ConnectionCallbacks.onConnectionSuspended
中:
Glide.get(getContext()).unregister(DriveId.class, InputStream.class);
列表中的适配器
:
String driveString = cursor.getString(cursor.getColumnIndex("image"));
DriveId driveId = DriveId.decodeFromString(driveString);
Glide.with(this)
.from(DriveId.class)
.load(driveId)
.into(imageView);
胶水:
import java.io.*;
import android.content.Context;
import android.net.Uri;
import com.bumptech.glide.load.data.DataFetcher;
import com.bumptech.glide.load.model.*;
import com.bumptech.glide.load.model.stream.StreamModelLoader;
import com.google.android.gms.common.api.GoogleApiClient;
import com.google.android.gms.drive.DriveId;
public class DriveIdModelLoader implements StreamModelLoader<DriveId> {
private final GoogleApiClient client;
public DriveIdModelLoader(GoogleApiClient client) {
this.client = client;
}
public DataFetcher<InputStream> getResourceFetcher(DriveId model, int width, int height) {
return new DriveIdDataFetcher(client, model);
}
public static class Factory implements ModelLoaderFactory<DriveId, InputStream> {
private final GoogleApiClient client;
public Factory(GoogleApiClient client) {
this.client = client;
}
public ModelLoader<DriveId, InputStream> build(Context context, GenericLoaderFactory factories) {
return new DriveIdModelLoader(client);
}
public void teardown() {
client.disconnect();
}
}
}
