Step 1: 添加以下代码到您的应用程序的 build.gradle 文件中

implementation 'com.razorpay:checkout:1.5.14'

Step 2: 在您的AndroidManifest.xml文件中添加以下权限。

Step 3: 添加以下代码到您的Activity

import com.razorpay.Checkout; import org.json.JSONObject;

public class MainActivity extends AppCompatActivity implements View.OnClickListener {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    //1.设置按钮的Click事件
    Button button = findViewById(R.id.button);
    button.setOnClickListener(this);

    //2.初始化Razorpay Checkout
    Checkout.preload(getApplicationContext());
}

@Override
public void onClick(View v) {
    //3.创建订单
    try {
        JSONObject options = new JSONObject();
        options.put("name", "宝贝的商品");
        options.put("description", "订单的拼音");
        options.put("image", "https://s3.amazonaws.com/rzp-mobile/images/rzp.png");
        options.put("currency", "INR");
        options.put("amount", "500");

        JSONObject preFill = new JSONObject();
        preFill.put("email", "[email protected]");
        preFill.put("contact", "9876543210");

        options.put("prefill", preFill);

        Checkout.open(this, options);
    } catch(Exception e) {
        Log.e("PAYMENT", "Error in starting Razorpay Checkout", e);
    }
}

//4.处理Razorpay的回调
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    //在onActivityResult方法中调用以下方法
    if (requestCode == Checkout.RA​​ZORPAY_PAYMENT_REQUEST_CODE) {
        RazorpayPaymentResultResult result = data.getParcelableExtra(Checkout​.EXTRA_RESULT);
        String status = result.getStatus();
        if (status.equals("成功")) {
            Toast.makeText(this, "支付成功", Toast.LENGTH_SHORT).show();
        } else {
            Toast.makeText(this, "支付失败", Toast.LENGTH_SHORT).show
