【问题描述】：
所以这是一个我已经处理了大约 2 个月的问题，我真的需要一些帮助。我正在做一个应用程序，我希望用户能够购买某些东西。
我已尽我所能遵循本指南：http://developer.android.com/google/play/billing/billing_integrate.html
问题是，我使用的是 Libgdx，这对我来说有点棘手。我得到了 AndroidLauncher 类中实现的大部分内容，这是我怀疑的主要内容。看起来像这样：
public class AndroidLauncher extends AndroidApplication {
IInAppBillingService mservice;
ServiceConnection connection = new ServiceConnection() {
public void onServiceConnected(ComponentName name, IBinder service) {
mservice = IInAppBillingService.Stub.asInterface(service);
}
@Override
public void onServiceDisconnected(ComponentName name) {
mservice = null;
}
};
@Override
protected void onCreate (Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
AndroidApplicationConfiguration config = new AndroidApplicationConfiguration();
initialize(new TombStone(null), config);
Intent serviceIntent = new Intent("com.android.vending.billing.InAppBillingService.BIND");
serviceIntent.setPackage("com.android.vending");
bindService(serviceIntent, connection, Context.BIND_AUTO_CREATE);
// The list the holds all the items available for purchase
ArrayList<String> skuList = new ArrayList<String> ();
skuList.add("premiumUpgrade");
skuList.add("gas");
Bundle querySkus = new Bundle();
querySkus.putStringArrayList("ITEM_ID_LIST", skuList);
try {
Bundle skuDetails = mservice.getSkuDetails(3, getPackageName(), "inapp", querySkus);
} catch (RemoteException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
@Override
protected void onDestroy() {
// TODO Auto-generated method stub
super.onDestroy();
if(mservice != null) {
unbindService(connection);
}
}
}
虽然该类不是实际“商店”屏幕所在的类。就是这个类：
public class Stones implements Screen {
OrthographicCamera camera;
final TombStone game;
private Stage stage;
private TextureAtlas atlas;
private Skin skin;
private Table table;
private BitmapFont font;
ImageButton btnArrow, btnArrowLeft, imageButton1, imageButton2, imageButton3, imageButton4, imageButton5, imageButton6;
public Texture background, testImage, arrow, arrowLeft;
public TextureAtlas buttonAtlas;
public Stones(TombStone gam) {
game = gam;
game.assets.load();
loadStore();
camera = new OrthographicCamera();
camera.setToOrtho(false, 136, 204);
}
public void loadStore() {
background = game.assets.storeBackground;
testImage = game.assets.image;
arrow = game.assets.arrow;
arrowLeft = game.assets.arrowLeft;
}
@Override
public void render(float delta) {
camera.update();
game.batch.setProjectionMatrix(camera.combined);
game.batch.begin();
game.batch.draw(background, 0, 0, 136, 204);
game.font.setScale(0.5f);
game.font.draw(game.batch, "This is the current selection of tombstones! Simply click the image of the stone you want to buy it.", 50, 200);
game.batch.end();
//Draws the ImageButtons
stage.act();
stage.draw();
}
@Override
public void resize(int width, int height) {
// TODO Auto-generated method stub
}
@Override
public void show() {
Skin skin = new Skin();
//ArrowButtons
Skin skinTwo = new Skin();
buttonAtlas = new TextureAtlas(Gdx.files.internal("arrow.pack"));
skinTwo.addRegions(buttonAtlas);
ImageButtonStyle styleTwo = new ImageButtonStyle();
TextureRegionDrawable arrowImage = new TextureRegionDrawable(new TextureRegion(new Texture("arrowLeft.png")));
styleTwo.up = skinTwo.newDrawable(skinTwo.newDrawable(arrowImage));
styleTwo.down = skinTwo.newDrawable(skinTwo.newDrawable(arrowImage));
//ImageButtons - Category buttons
ImageButtonStyle style = new ImageButtonStyle();
TextureRegionDrawable ibimage = new TextureRegionDrawable(new TextureRegion(new Texture("image.png")));
style.up = skin.newDrawable(skin.newDrawable(ibimage));
style.down = skin.newDrawable(skin.newDrawable(ibimage));
imageButton1 = new ImageButton(style);
imageButton2 = new ImageButton(style);
imageButton3 = new ImageButton(style);
imageButton4 = new ImageButton(style);
imageButton5 = new ImageButton(style);
imageButton6 = new ImageButton(style);
//ArrowButtons implement
btnArrow = new ImageButton(styleTwo);
btnArrow.setSize(150, 150);
btnArrow.setPosition(450, 10);
/*table = new Table();
table.setBounds(100, 100, 100, 100);
skin = new Skin();
font = new BitmapFont();
TextureRegion image = new TextureRegion(testImage);
stage = new Stage();
Gdx.input.setInputProcessor(stage);
//ImageButtonStyle style = new ImageButtonStyle(skin.get(ButtonStyle.class));
//style.imageUp = new TextureRegionDrawable(image);
//style.imageDown = new TextureRegionDrawable(image);
ImageButton iconButton = new ImageButton(skin);
//Button imgButton = new Button(new Image(image), skin);*/
//Stage for the BuyImages
stage = new Stage();
table = new Table();
table.setBounds(20, 320, 175, 1050);
table.add(imageButton1).pad(5).size(175, 175).row();
table.add(imageButton2).pad(5).size(175, 175).row();
table.add(imageButton3).pad(5).size(175, 175).row();
table.add(imageButton4).pad(5).size(175, 175).row();
table.add(imageButton5).pad(5).size(175, 175).row();
table.add(imageButton6).pad(5).size(175, 175).row();
stage.addActor(table);
stage.addActor(btnArrow);
Gdx.input.setInputProcessor(stage);
//Backbutton
btnArrow.addListener(new ChangeListener() {
@Override
public void changed(ChangeEvent event, Actor actor) {
game.setScreen(new StoreScreen(game));
}
});
imageButton1.addListener(new ChangeListener() {
@Override
public void changed(ChangeEvent event, Actor actor) {
}
});
}
@Override
public void hide() {
// TODO Auto-generated method stub
}
@Override
public void pause() {
// TODO Auto-generated method stub
}
@Override
public void resume() {
// TODO Auto-generated method stub
}
@Override
public void dispose() {
// TODO Auto-generated method stub
}
}
所以我怀疑我需要以某种方式将第一个类链接到第二个类才能使用我在第一个类中实现的东西？但是怎么做？在那之后，我有点迷路了。 我看过一堆教程，但没有一个更具体地描述了我的问题。 帮助将是巨大的！ 提前致谢
