Glide緩存Simple

1. 緩存路徑的指定
2. 緩存大小的獲取
3. 磁盤緩存清除(兩種方法)

4. 內存緩存清除

   • 可clone之後查看使用Simple

Glide cache Simple.

1. The cache path specified
2. The cache size
3. The disk cache (two ways)

4. Memory cache to clearMay

   • use Simple clone after check

獲取Glide磁盤緩存大小

public String getCacheSize() {
    try {
        return getFormatSize(getFolderSize(new File(Application.getInstance().getCacheDir() + "/" + GlideCatchConfig.GLIDE_CARCH_DIR)));
    } catch (Exception e) {
        e.printStackTrace();
        return "獲取失敗";
    }
}

清除Glide磁盤緩存

public boolean cleanCatchDisk() {
    return deleteFolderFile(Application.getInstance().getCacheDir() + "/" + GlideCatchConfig.GLIDE_CARCH_DIR, true);
}

public boolean clearCacheDiskSelf() {
    try {
        if (Looper.myLooper() == Looper.getMainLooper()) {
            new Thread(new Runnable() {
                @Override
                public void run() {
                    Glide.get(Application.getInstance()).clearDiskCache();
                }
            }).start();
