我成立了魔域InAppBilling例如本地，我准备尝试一下，但我有点困惑。我有这样一个按钮：

I set up the "Dungeons" InAppBilling example locally and I am ready to try it out, but I am a bit confused. I have a button like this:

Button donate = (Button)findViewById(R.id.donate);     
donate.setOnClickListener(new Button.OnClickListener() {  
        public void onClick(View v) {     
        // But what do I do here? :)
        }
});

和被调用时，做什么我需要做的其实转至Android商店的薪酬屏幕？

And when it is called, what do I need to do to actually go to the pay screen on android store?

谢谢！

推荐答案

1）下载

http://developer.android.com/guide/google/play/billing/billing_integrate.html#billing-download

2）添加

http://developer.android.com/guide/google/play/billing/billing_integrate.html#billing-add-aidl

3）在你的Andr​​oid清单文件添加权限

3)add permission in your android manifest file

http://developer.android.com/guide/google/play/billing/billing_integrate.html#billing-permission

现在你的项目应该是这样的......

now your project should look like this...

4）将公共密钥（你可以找到它在开发者控制台     的编辑个人资料底部）在Security.java在网上说     字符串base64En codedPublicKey =在这里你的公钥

4) place the public key (you can find it in developer console in the bottom section of edit profile) in the Security.java in line saying String base64EncodedPublicKey = "your public key here"

5），最后你的活动具有按钮应该是这个样子

5) and finally your activity which have button should be look like this

公共类YourActivity扩展活动实现OnClickListener {     字符串iss​​ueProductId =你的产品ID;

public class YourActivity extends Activity implements OnClickListener { String issueProductId = "Your Product ID";

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.updates);
    SetInAppBilling();
    Button donate = (Button) findViewById(R.id.donate);
    donate.setOnClickListener(new Button.OnClickListener() {
        public void onClick(View v) {
            if (mBillingService.requestPurchase(issueProductId, null)) {

            } else {
                showDialog(DIALOG_BILLING_NOT_SUPPORTED_ID);
                Log.i("tag", "Can't purchase on this device");

            }

        }
    });
}
