Android支付-银联支付

原文转自：/article/1553250.html，感谢作者分享！

银联支付也是一般比较常用的支付功能,这里简单了介绍android app如果短期快速应用这一方面的东西。直接上代码：

1.导入银联支付的依赖包:



2.在res目录下增加资源包:



3.配置AndroidManifest.xml文件配置打开的activity:

[html] view
plaincopyprint?





<activity

android:name="com.unionpay.uppay.PayActivity"

android:configChanges="orientation|keyboardHidden"

android:excludeFromRecents="true"

android:label="@string/app_name"

android:screenOrientation="portrait"

android:windowSoftInputMode="adjustResize" />

至此,我们的项目环境就搭好了.(以上资料文件,请查看银联测试文档目录的androiddemo);

银联支付代码3步骤：

1.获取TN号 2.请求控件界面（PayActivity）

3.ActivityResult处理支付结果（但该结果并不一定正确 ，因为银联系统通过异步返回给服务器和我们的app是同时异步的）



以下 我以测试接口为例

[java] view
plaincopyprint?





/**

* UnionPay Test

*

* @author Lean @date:2014-8-8

*/

public class MainActivity extends Activity implements Runnable {



private String mMode = "01";//设置测试模式:01为测试 00为正式环境

private static final String TN_URL_01 = "http://202.101.25.178:8080/sim/gettn";//自己后台需要实现的给予我们app的tn号接口



private Handler mHandler=new Handler(){



public void handleMessage(android.os.Message msg) {



String tn = "";

if (msg.obj == null || ((String) msg.obj).length() == 0) {

AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);

builder.setTitle("错误提示");

builder.setMessage("网络连接失败,请重试!");

builder.setNegativeButton("确定",

new DialogInterface.OnClickListener() {

@Override

public void onClick(DialogInterface dialog, int which) {

dialog.dismiss();

}

});

builder.create().show();

} else {

tn = (String) msg.obj;

doStartUnionPayPlugin(MainActivity.this, tn, mMode);

}

}

};



/**

* 启动支付界面

*/

public void doStartUnionPayPlugin(Activity activity, String tn, String mode) {

UPPayAssistEx.startPayByJAR(activity, PayActivity.class, null, null,

tn, mode);

}





@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);



new Thread(MainActivity.this).start();



}





@Override

public void run() {

String tn = null;

InputStream is;

try {



String url = TN_URL_01;



URL myURL = new URL(url);

URLConnection ucon = myURL.openConnection();

ucon.setConnectTimeout(120000);

is = ucon.getInputStream();

int i = -1;

ByteArrayOutputStream baos = new ByteArrayOutputStream();

while ((i = is.read()) != -1) {

baos.write(i);

}



tn = baos.toString();

is.close();

baos.close();

} catch (Exception e) {

e.printStackTrace();

}



Message msg = mHandler.obtainMessage();

msg.obj = tn;

mHandler.sendMessage(msg);

}



@Override

protected void onActivityResult(int requestCode, int resultCode, Intent data) {

if (data == null) {

return;

}

String msg = "";

/*

* 支付控件返回字符串:success、fail、cancel 分别代表支付成功，支付失败，支付取消

*/

String str = data.getExtras().getString("pay_result");

Log.v("zftphone", "2 "+data.getExtras().getString("merchantOrderId"));

if (str.equalsIgnoreCase("success")) {

msg = "支付成功！";



} else if (str.equalsIgnoreCase("fail")) {

msg = "支付失败！";



} else if (str.equalsIgnoreCase("cancel")) {



msg = "用户取消了支付";

}

//支付完成,处理自己的业务逻辑!

}



}
