本文介绍了如何在Android应用中使用Glide库进行图片加载，强调了设置占位图和错误图的方法，并详细探讨了如何配置加载图片到外部存储的路径。

Glide占位图和错误图

 Glide.with(context).load(result.get(i).getMasterPic())
                .apply(RequestOptions.circleCropTransform())
                //占位图
                .placeholder(R.drawable.ic_launcher_background)
                //错误图
                .error(R.drawable.ic_launcher_foreground)
                .into(viewHolder.imageView);

外部存储路径

package yanjupeng.bawei.com.zuoye.glide;


import android.content.Context;
import android.os.Environment;
import android.support.annotation.NonNull;

import com.bumptech.glide.Glide;
import com.bumptech.glide.GlideBuilder;
import com.bumptech.glide.Registry;
import com.bumptech.glide.load.engine.cache.DiskLruCacheFactory;
import com.bumptech.glide.module.AppGlideModule;
@com.bumptech.glide.annotation.GlideModule
public class GlideUtileModel  extends AppGlideModule {

    @Override
    public void applyOptions(@NonNull Context context, @NonNull GlideBuilder builder) {
        int size = 100 * 1024 * 1024;
        String dir = getStorageDirectory()+ "/wooo";
        path = context.getCacheDir().getPath();

        builder.setDiskCache(new DiskLruCacheFactory(dir , size));


    }

    //外部路径
    private String sdRootPath = Environment.getExternalStorageDirectory().getPath();
    private String path = null;


    private String getStorageDirectory(){
        return Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED) ?
                sdRootPath : path;
    }



    @Override
    public void registerComponents(@NonNull Context context, @NonNull Glide glide, @NonNull Registry registry) {

    }
}
