如何在一个片段上启动Zxing? [英] how to start Zxing on a Fragment?

问题描述

我有一个活动，其中包含两个片段，我想在其中一个片段上运行ZXING扫描器，

i have an activity that holds Two Fragments, i want to run ZXING scanner on one of the fragments,

目前，我是在其他类似这样的活动上进行此操作

currently i do this on another activity like this >

new IntentIntegrator(this).initiateScan(); // opens up Scan intent > ZXING

我该怎么做，但要打开对片段的扫描?

how do i do that line but to open up the scan on a fragment ?

我也可以在这样的接收器上获得ZXING结果>

Also i get the ZXING results on a reciever like this >

//results when activity enters a callback sent out to another activity
    public void onActivityResult(int requestCode, int resultCode, Intent intent) {

我将如何在要运行Zxing的Fragment上获取它们?

how will i get them on my Fragment that i'm going to run Zxing on ?

使用getActivity()在 IntentIntegrator 中以以下方式传递上下文:

Use getActivity() to pass Context in IntentIntegrator as:

new IntentIntegrator(getActivity()).initiateScan(); 

我将如何在要运行Zxing的Fragment上获取它们?

how will i get them on my Fragment that i'm going to run Zxing on ?

在两个 super.onActivityResult(requestCode，resultCode，data); 行中的Fragment容器Activity中使用

覆盖 onActivityResult ；在Fragment中，仅覆盖 onActivityResult 方法.

override onActivityResult in both Fragment container Activity with super.onActivityResult(requestCode, resultCode, data); line and in Fragment just override onActivityResult method.
