集成支付宝sdk
链接：官方文档
1、导入依赖
dependencies {
// 添加下方的内容
api 'com.alipay.sdk:alipaysdk-android:+@aar'
// ... 其它依赖项
}
2、依赖导入后在AndroidManifest.xml文件里添加 下面两个类
<activity
android:name="com.alipay.sdk.app.H5PayActivity"
android:configChanges="orientation|keyboardHidden|navigation|screenSize"
android:exported="false"
android:screenOrientation="behind"
android:windowSoftInputMode="adjustResize|stateHidden"
tools:replace="android:configChanges" />
<activity
android:name="com.alipay.sdk.app.H5AuthActivity"
android:configChanges="orientation|keyboardHidden|navigation"
android:exported="false"
android:screenOrientation="behind"
android:windowSoftInputMode="adjustResize|stateHidden"
tools:replace="android:configChanges" />
3、创建支付返回的接口回调 success/error
public class PayResult {
private String resultStatus;
private String result;
private String memo;
public PayResult(Map<String, String> rawResult) {
if (rawResult == null) {
return;
}
for (String key : rawResult.keySet()) {
if (TextUtils.equals(key, "resultStatus")) {
resultStatus = rawResult.get(key);
} else if (TextUtils.equals(key, "result")) {
result = rawResult.get(key);
} else if (TextUtils.equals(key, "memo")) {
memo = rawResult.get(key);
}
}
}
@Override
public String toString() {
return "resultStatus={" + resultStatus + "};memo={" + memo
+ "};result={" + result + "}";
}
/**
* @return the resultStatus
*/
public String getResultStatus() {
return resultStatus;
}
/**
* @return the memo
*/
public String getMemo() {
return memo;
}
/**
* @return the result
*/
public String getResult() {
return result;
}
}
4、创建自己应用的支付的类
例如：这里包含了微信支付忽略掉就好
public class PayActivity extends BaseActivity<ActivityPayBinding> implements IWXAPIEventHandler {
private static final int SDK_PAY_FLAG = 1;
private String orderInfo; // 订单Id
private String accessToken;
private IWXAPI api;
private boolean paySuccess = false;
private Handler mHandler = new Handler() {
@SuppressLint("HandlerLeak")
@Override
public void handleMessage(@NonNull Message msg) {
super.handleMessage(msg);
switch (msg.what) {
case SDK_PAY_FLAG: {
@SuppressWarnings("unchecked")
PayResult payResult = new PayResult((Map<String, String>) msg.obj);
/**
* 对于支付结果，请商户依赖服务端的异步通知结果。同步通知结果，仅作为支付结束的通知。
*/
String resultInfo = payResult.getResult();// 同步返回需要验证的信息
String resultStatus = payResult.getResultStatus();
// 判断resultStatus 为9000则代表支付成功
// 9000为支付成功
// 4000为支付失败
// 6001为取消支付
// 8000为支付结果确认中
if (TextUtils.equals(resultStatus, "9000")) {
// 该笔订单是否真实支付成功，需要依赖服务端的异步通知。
showToast("支付成功");
mViewBinding.paySuccessLayout.payRoot.setVisibility(View.VISIBLE);
mViewBinding.payPriceLayout.setVisibility(View.GONE);
mViewBinding.titleBar.textTitle.setVisibility(View.GONE);
mViewBinding.surePay.setVisibility(View.GONE);
paySuccess = true;
} else {
// 该笔订单真实的支付结果，需要依赖服务端的异步通知。
showToast("取消支付");
}
break;
}
}
}
};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// 初始化支付宝SDK
PayTask payTask = new PayTask(this);
// 初始化微信支付API
api = WXAPIFactory.createWXAPI(PayActivity.this, Contents.APP_ID);
}
@Override
protected void initView() {
mViewBinding.titleBar.textTitle.setText("安全收银台");
String price = getIntent().getExtras().getString("price");
orderInfo = getIntent().getExtras().getString("orderCode");
accessToken = getSharedPreferences("UserInformation", Context.MODE_PRIVATE).getString("access_token", "");
mViewBinding.payPrice.setText(price);
