1.清除缓存异步操作

public class ClearCacheTask extends AsyncTask<String, Integer, String>{      @Override      protected String doInBackground(String... params) {         ImageLoader.getInstance().clearDiscCache();         ImageLoader.getInstance().clearMemoryCache();         return null;      }      @Override      protected void onCancelled() {         super.onCancelled();      }      @Override      protected void onPostExecute(String result) {         super.onPostExecute(result);         clearBtn.setText("清除缓存（0MB）");         Util.showShortToast(SettingsActivity.this, "缓存已清空！");      }      @Override      protected void onPreExecute() {         super.onPreExecute();      }      @Override      protected void onProgressUpdate(Integer... values) {         super.onProgressUpdate(values);      }   }   2.引用

private void clearCache() {   dlg.setMessage("正在清空缓存...");   dlg.show();   ClearCacheTask task = new ClearCacheTask();   task.execute("");}
3.long fileSize = FileUtil.getFileSize(FileUtil.cachePath)/(1024*1024);
清除了fileSize+“M”；
