我正在尝试创建一个可以使用万事达卡 api 通过信用卡支付的 android 应用程序。我正在关注本教程->> https://developer.mastercard.com/portal/pages/viewpage.action?pageId=14876685 但它说找不到该网址。

这是我使用的代码:

public class MainActivity extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
        StrictMode.setThreadPolicy(policy); 

        ((Button) findViewById(R.id.submit)).setOnClickListener(new View.OnClickListener() {

            public void onClick(View v) {
                // TODO Auto-generated method stub
                Context context = getApplicationContext();
                String endPoint = "https://api.mastercard.com/payments/v1/purchase?Format=XML";
                EditText cardNumberInput = (EditText) findViewById(R.id.cardNumberInput);
                EditText expirationMonthInput = (EditText) findViewById(R.id.expirationMonthInput);
                EditText expirationYearInput = (EditText) findViewById(R.id.expirationYearInput);
                EditText cvvInput = (EditText) findViewById(R.id.cvvInput);
                EditText cardHolderNameInput = (EditText) findViewById(R.id.cardHolderNameInput);
                EditText amountInput = (EditText) findViewById(R.id.amountInput);

                final double amount = Float.valueOf(amountInput.getText().toString());

                    toast.show();
                }
            }
        });
    }
}

任何想法都会对我有很大帮助。谢谢。

这就是日志猫所说的:

-在 UI 线程上做UI 工作总是更好,在非 UI 线程上工作非 UI 工作,但从Android's Honeycomb版本来看它是一个法律。

-所以你的网络调用使用后台线程

-要么使用Thread网络调用,然后将数据放在 UI 上,Handler要么使用 Android 中所谓的无痛线程AsyncTask.
