ASimpleCache 是一个为android制定的 轻量级的 开源缓存框架。轻量到只有一个java文件(由十几个类精简而来)。. 特色主要是: 1:轻,轻到只有一个JAVA文件。 2:可配置,可以配置缓存路径,缓存大小,缓存数量等。 3:可以设置缓存超时时间,缓存超时自动失效,并被删除。 4:支持多进程。 3、它在android中可以用在哪些场景?. 1、替换SharePreference当做配置文件 2、可以缓存网络请求数据,比如oschina的android客户端可以缓存http请求的新闻内容,缓存时间假设为1个小时,超时后自动失效,让客户端重新请求新的数据,减少客户端流量,同时减少服务器并发量。 3、您来说... 4、如何使用 ASimpleCache?. ACache mCache = ACache.get(this); mCache.put("test_key1", "test value"); mCache.put("test_key2", "test value", 10);//保存10秒,如果超过10秒去获取这个key,将为null mCache.put("test_key3", "test value", 2 * ACache.TIME_DAY);//保存两天,如果超过两天去获取这个key,将为null 获取数据. ACache mCache = ACache.get(this); String value = mCache.getAsString("test_key1");. //获取缓存对象 ACache mCache = ACache.get(this);. mCache.remove(CACHE_KEY);//清除缓存 put(String key, Obeject value, int saveTime);//设置缓存时间. String testString = mCache.getAsString("testString");. JSONObject jsonObject = new JSONObject();. jsonObject.put("name", "Yoson"); jsonObject.put("age", 18);. JSONObject testJsonObject = mCache.getAsJSONObject("testJsonObject");. 3.存取Json数组 JSONArray jsonArray = new JSONArray();. JSONObject yosonJsonObject = new JSONObject(); jsonObject.put("name", "Yoson"); jsonObject.put("age", 18);. JSONObject michaelJsonObject = new JSONObject(); michaelJsonObject.put("name", "Michael"); michaelJsonObject.put("age", 25);. mCache.put("testJsonArray", jsonArray);//存储json数组 JSONArray testJsonArray = mCache.getAsJSONArray("testJsonArray");//读取json数组. Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.img_test);. mCache.put("testBitmap", bitmap); Bitmap testBitmap = mCache.getAsBitmap("testBitmap");. Drawable drawable = getResources().getDrawable(R.drawable.img_test);. mCache.put("testDrawable", drawable); Drawable testDrawable = mCache.getAsDrawable("testDrawable");. UserBean userBean = new UserBean(); userBean.setAge("18"); userBean.setName("HaoYoucai");. mCache.put("testObject", userBean); UserBean testObject = (UserBean) mCache.getAsObject("testObject");. //保存 @Override public void run() { OutputStream ostream = null; try { ostream = mCache.put(CACHE_KEY); } catch (FileNotFoundException e) { e.printStackTrace(); } if (ostream == null){ Toast.makeText(this, "Open stream error!", Toast.LENGTH_SHORT) .show(); return; } try { URL u = new URL(mUrl); HttpURLConnection conn = (HttpURLConnection) u.openConnection(); conn.connect(); InputStream stream = conn.getInputStream();. //读取 public void read(View v) { InputStream stream = null; try { stream = mCache.get(CACHE_KEY); } catch (FileNotFoundException e) { e.printStackTrace(); } if (stream == null) { Toast.makeText(this, "Bitmap cache is null ...", Toast.LENGTH_SHORT) .show(); text.setText("file not found"); return; } try { text.setText("file size: " + stream.available()); } catch (IOException e) { text.setText("error " + e.getMessage()); } }.

QUESTION
how to run loading Dialog while program write in database
...ANSWER
Answered 2019-Jun-23 at 00:34If you are going to use a splash screen while performing a task then that task should consume at least 1 second, if it is less likely the user will not be able to visualize how fast the window will open and close. Considering the above, this task must be executed in another thread, so I have created a QObject that emits a signal before and after executing the task, those signals serve to show and close the window.
QUESTION
I'm working in a data processing desktop application with Python 3.7 and PySide2 on which requires me to load data from several large (approx 250k rows) excel files into the program's processing library. For this I've set up in my application a simple popup (called LoadingPopup) which includes a rotating gif and a simple caption, and also some code that loads the data from the excel files into a global object using pandas. Both of these things work as intended when run on their own, but if I happen to create a loading dialog and a QRunnable worker in the same scope of my codebase, the widgets contained in loading widget (a gif and a simple caption) will simply not show.
I've tried changing the parent type for my widget from QDialog to QWidget, or initializing the popup (the start() function) both outside and inside the widget. I'm not very experienced with Qt5 so I don't know what else to do.

Answered 2019-Apr-17 at 20:35You should not call the run method directly since you will have the heavy task run on the GUI thread freezing it. You must launch it using QThreadPool:
QUESTION
I'm having problems getting any video player to work with my PyQt4 setup (having tried both phonon and QMovie). The below QMovie script is from an example where several users commented it as functional. For me, it runs but only opens a window (with Loading...
centered) that never actually plays the .gif (I've tried several working .gif files from numerous examples online, so the file is not the problem). I've commented out the results from running the three debugging steps as well.
What can I do next?

QUESTION
I'm making a large program in Python and using PyQt for the GUI. The whole program is divided into different modules so that different people can work on it simultaneously without interfering with the other people's work.
I am working on 3 different modules right now. 1 is the main program window that handles the basic UI and assigns widgets so the main window (this is not important, just so you know why the code doesn't look like a full program.)
First is the widget:

Answered 2017-Jan-22 at 17:44When you use connect it is necessary to pass the name of the function since internally it is in charge of calling it, in your case you have to call it directly so you will have to pass its parameters, in this case event:
