在设备的本地存储上创建一个Android保存文件? [英] Creating an Android save file on the local storage of the device?
问题描述
我在Android上使用Libgdx进行游戏,并且我想在用户手机的本地存储上创建一个保存文件,我想知道如何去做这件事。我读过的一些文件如下: https:// developer.android.com/guide/topics/data/data-storage.html#filesInternal 一直都很模糊,我也不太明白发生了什么,或者可以让我的例子在我自己的游戏中运行。 Libgdx本身是否有这个功能?
I'm using Libgdx for a game on Android, and i want to create a save file on the local storage of the user's phone, and i'm wondering how would i go about doing that. Some of the documents I have read such as here: https://developer.android.com/guide/topics/data/data-storage.html#filesInternal have been quiet vague, and I don't really understand what is going on, or can make the example work in my own game. Is there a feature for this in Libgdx itself?
推荐答案
在libgdx中用于存储我们使用Preference的数据。这有助于将数据存储在设备本身中。在这里我将给你一个例子,用于将数据存储在deveice内存中。
in libgdx for storing the data we uses the "Preference". which is help to store the data in device itself. here i will give you an example for storing the data in deveice memory.
myGame extends ApplicationAdapter{
public static int count;
public static bitmapFont font;
public SpriteBatch batch;
public static Preferences prefs;
public void create()
{
batch=new SpriteBatch();
font=new font(Gdx.files.internla("myFont.png"));
public static Preferences prefs;
// this is for setting up the storage for the current project
prefs = Gdx.app.getPreferences("myGame");
}
public void incrementCount()
{
count++;
if(count>100){
// here "countValue" is the key(which is the reference to the data) and "count" is the vlaue(the data). the value is stored in key value method.
prefs.putInteger("countValue", count);
// is used to flush the data in to the storage
prefs.flush();
}
public void render()
{
// getting the stored value from the preference
pref.getInteger("countValue",countValue);
batch.begin();
batch.draw(font,countValue+"stored value",0,0)
batch.end()
}
// this is the simple way to store the data into the device memory . it will work in both the android and the IOS
