问题描述
我写的Android应用程序，我使用时，应用内计费与使用共享preferences节省int变量的困难。我想50点添加到我的int变量，然后将其保存与共享preferences。当购买完成后，用户什么也没得到，但它表示，支付Succesfull.How我应该添加和保存了50分？
下面是我的code：
私有静态最后弦乐HINT =提示;
私有静态最后的字符串值=VALUE;
诠释提示;私有静态最后的字符串标记=
com.game.example;
com.game.example.util.IabHelper mHelper;
静态最后弦乐ITEM_SKU =com.fifty.points;私人按钮clickButton;
私人按钮buyButton;
按钮BTN;

解决方案
的
本类简化了在线路code的调用共享preferences。它也可以做更多的，如：保存字符串，整数和保存图像的列表。在所有1号线code的！
实例：
TinyDB tinydb =新TinyDB（背景）;tinydb.putInt（的clickCount，2）;
tinydb.putFloat（XPOINT，3.6f）;
tinydb.putLong（USERCOUNT位，39832L）;tinydb.putString（username的，约翰）;
tinydb.putBoolean（isUserMale，真正的）;tinydb.putList（MyUsers，mUsersArray）;
tinydb.putImagePNG（DropBox的/ WorkImages，MeAtlunch.png，lunchBitmap）;//这些再加上相应的get方法都包括在内
这只是它是多么容易用一个例子。有包含在类更多的有用的方法。享受:)
I'm writing an application for android and I have difficulties with saving int variable with SharedPreferences when using In-App billing. I'd like to add 50 points to my int variable and then save it with SharedPreferences. When the purchase is finished the user got nothing, but it said Payment Succesfull.How should I add and save the 50 points?
Here is my code:
private static final String HINT = "Hint";
private static final String VALUE = "VALUE";
int hints;
private static final String TAG =
"com.game.example";
com.game.example.util.IabHelper mHelper;
static final String ITEM_SKU = "com.fifty.points";
private Button clickButton;
private Button buyButton;
Button btn;
@Override
protected void onCreate(Bundle savedInstanceState) {
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_pontpiac);
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
this.setContentView(R.layout.activity_pontpiac);
android.support.v7.app.ActionBar actionbar = getSupportActionBar();
actionbar.hide();
SharedPreferences sphint = getApplicationContext().getSharedPreferences(HINT, MODE_PRIVATE);
hints = sphint.getInt(VALUE, 0);
buyButton = (Button)findViewById(R.id.buyButton);
clickButton = (Button)findViewById(R.id.clickButton);
clickButton.setEnabled(false);
String base64EncodedPublicKey =

解决方案
TinyDB -- Android-Shared-Preferences-Turbo
This class simplifies calls to SharedPreferences in a line of code. It can also do more like: saving a list of strings, integers and saving images. All in 1 line of code!
Example usage:
TinyDB tinydb = new TinyDB(context);
tinydb.putInt("clickCount", 2);
tinydb.putFloat("xPoint", 3.6f);
tinydb.putLong("userCount", 39832L);
tinydb.putString("userName", "john");
tinydb.putBoolean("isUserMale", true);
tinydb.putList("MyUsers", mUsersArray);
tinydb.putImagePNG("DropBox/WorkImages", "MeAtlunch.png", lunchBitmap);
//These plus the corresponding get methods are all included
This is just an example of how easy it is to use. There are many more usefull methods included in the class. Enjoy :)
