GlideCatchUtil

一、在Glide加载图片时，有时需要清理一些缓存，接下来无疑就是清楚缓存的工具类。

/** * Created by ylzx on 2017/3/10. */public class GlideCatchUtil {    private static GlideCatchUtil instance;    public static GlideCatchUtil getInstance() {        if (null == instance) {            instance = new GlideCatchUtil();        }        return instance;    }    // 获取Glide磁盘缓存大小    public String getCacheSize() {        try {            return getFormatSize(getFolderSize(new File(MyApplication.getContext().getCacheDir() + "/" + GlideCatchConfig.GLIDE_CARCH_DIR)));        } catch (Exception e) {            e.printStackTrace();            return "获取失败";        }    }    // 清除Glide磁盘缓存，自己获取缓存文件夹并删除方法    public boolean cleanCatchDisk() {        return deleteFolderFile(MyApplication.getContext().getCacheDir() + "/" + GlideCatchConfig.GLIDE_CARCH_DIR, true);    }    // 清除图片磁盘缓存，调用Glide自带方法    public boolean clearCacheDiskSelf() {        try {            if (Looper.myLooper() == Looper.getMainLooper()) {                new Thread(new Runnable() {                    @Override                    public void run() {                        Glide.get(MyApplication.getContext()).clearDiskCache();                    }                }).start();            } else {                Glide.get(MyApplication.getContext()).clearDiskCache();            }            return true;        } catch (Exception e) {            e.printStackTrace();            return false;        }    }    // 清除Glide内存缓存    public static boolean clearCacheMemory() {        try {            if (Looper.myLooper() == Looper.getMainLooper()) { //只能在主线程执行                Glide.get(MyApplication.getContext()).clearMemory();                return true;            }        } catch (Exception e) {            e.printStackTrace();        }        return false;    }    // 获取指定文件夹内所有文件大小的和    private long getFolderSize(File file) throws Exception {        long size = 0;        try {            File[] fileList = file.listFiles();            for (File aFileList : fileList) {                if (aFileList.isDirectory()) {                    size = size + getFolderSize(aFileList);                } else {                    size = size + aFileList.length();                }            }        } catch (Exception e) {            e.printStackTrace();        }        return size;    }    // 格式化单位    private static String getFormatSize(double size) {        double kiloByte = size / 1024;        if (kiloByte < 1) {            return size + "Byte";        }        double megaByte = kiloByte / 1024;        if (megaByte < 1) {            BigDecimal result1 = new BigDecimal(Double.toString(kiloByte));            return result1.setScale(2, BigDecimal.ROUND_HALF_UP).toPlainString() + "KB";        }        double gigaByte = megaByte / 1024;        if (gigaByte < 1) {            BigDecimal result2 = new BigDecimal(Double.toString(megaByte));            return result2.setScale(2, BigDecimal.ROUND_HALF_UP).toPlainString() + "MB";        }        double teraBytes = gigaByte / 1024;        if (teraBytes < 1) {            BigDecimal result3 = new BigDecimal(Double.toString(gigaByte));            return result3.setScale(2, BigDecimal.ROUND_HALF_UP).toPlainString() + "GB";        }        BigDecimal result4 = new BigDecimal(teraBytes);        return result4.setScale(2, BigDecimal.ROUND_HALF_UP).toPlainString() + "TB";    }    // 按目录删除文件夹文件方法    private boolean deleteFolderFile(String filePath, boolean deleteThisPath) {        try {            File file = new File(filePath);            if (file.isDirectory()) {                File files[] = file.listFiles();                for (File file1 : files) {                    deleteFolderFile(file1.getAbsolutePath(), true);                }            }            if (deleteThisPath) {                if (!file.isDirectory()) {                    file.delete();                } else {                    if (file.listFiles().length == 0) {                        file.delete();                    }                }            }            return true;        } catch (Exception e) {            e.printStackTrace();            return false;        }    }}

二、另一个定义的工具类

public class GlideConfiguration implements GlideModule {    @Override    public void applyOptions(Context context, GlideBuilder builder) {        //自定义缓存目录        builder.setDiskCache(new InternalCacheDiskCacheFactory(context,                GlideCatchConfig.GLIDE_CARCH_DIR,                GlideCatchConfig.GLIDE_CATCH_SIZE));    }    @Override    public void registerComponents(Context context, Glide glide) {        //nil    }}

三、其次还需再来一个

public class GlideCatchConfig {    // 图片缓存最大容量，150M，根据自己的需求进行修改    public static final int GLIDE_CATCH_SIZE = 150 * 1000 * 1000;    // 图片缓存子目录    public static final String GLIDE_CARCH_DIR = "image_catch";}

四、最后需配置一下 需要在AndroidManifest.xml中声明

     <meta-data     android:name="com.yaphetzhao.glidecatchsimple.glide.GlideConfiguration"    android:value="GlideModule" />
