android studio接入支付宝_android studio 支付宝支付

支付宝后台申请appid 秘钥…等数据
1.将支付宝的libs下的jar拷贝到自己项目中

添加为依赖库
2.在Androidmanifest.xml中添加

    <activity
        android:name="com.alipay.sdk.app.H5PayActivity"
        android:configChanges="orientation|keyboardHidden|navigation|screenSize"
        android:exported="false"
        android:screenOrientation="behind"
        android:windowSoftInputMode="adjustResize|stateHidden" >
    </activity>
    <activity
        android:name="com.alipay.sdk.app.H5AuthActivity"
        android:configChanges="orientation|keyboardHidden|navigation"
        android:exported="false"
        android:screenOrientation="behind"
        android:windowSoftInputMode="adjustResize|stateHidden" >
    </activity>

    <!-- 支付宝 sdk end -->

3.在需要调用的地方调用支付宝接口

创建一个PayResult类：
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.调用支付宝,签名，参数都通过服务端做，通过服务端拿到数据
//支付宝支付
public void callAliPay() {
connectAlipayWeb();
}
private List params = new ArrayList();
public String post(String url) {
String rev = “”;
org.apache.http.HttpResponse httpResponse = null;
org.apache.http.client.methods.HttpPost httpPost = new org.apache.http.client.methods.HttpPost(url);
try {
httpPost.setEntity(new org.apache.http.client.entity.UrlEncodedFormEntity(params, “UTF-8”));
httpResponse = (new org.apache.http.impl.client.DefaultHttpClient()).execute(httpPost);
if (httpResponse.getStatusLine().getStatusCode() == 200) {
rev = EntityUtils.toString(httpResponse.getEntity());
}
} catch (Exception var6) {
var6.printStackTrace();
}
params.clear();
return rev;
}
private void connectAlipayWeb() {
new Timer().schedule(new TimerTask() {
@Override
public void run() {
params.add(new BasicNameValuePair(“method”, “xxxx”));
params.add(new BasicNameValuePair(“key”, “xxxxxx”));
params.add(new BasicNameValuePair(“payType”, payType));//1支付宝 0微信
params.add(new BasicNameValuePair(“orderId”,Manager.getInstance().js_order));//Manager.getInstance().js_order
String result = post(“自己服务地址”);
Log.d(“gmf result:”,result);
String orderInfo=result;
toALiPay(activity,orderInfo);
return;
}
}, 0);
}
/**
* 签名在服务端来做
*
* @param context
* @param orderInfo
*/
public void toALiPay(final Activity context, final String orderInfo) {
Runnable payRunnable = new Runnable() {

        @Override
        public void run() {
            PayTask alipay = new PayTask(context);
            Map<String, String> result = alipay.payV2(orderInfo, true);
            Message msg = new Message();
            msg.what = SDK_PAY_FLAG;
            msg.obj = result;
            mHandler.sendMessage(msg);
        }
    };

    Thread payThread = new Thread(payRunnable);
    payThread.start();
}
//支付宝 监听回调函数
@SuppressLint("HandlerLeak")
private Handler mHandler = new Handler() {
    @SuppressWarnings("unused")
    public void handleMessage(Message msg) {
        switch (msg.what) {
            case SDK_PAY_FLAG: {//支付宝支付
                @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
                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。
