请检查我的代码如下：二手变形杆菌在Android碎片，但得到一个错误，而铸造吹气 - 变形的Android布局引擎

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
    JSONObject jsonlayout = null ; 
    try { 
     jsonlayout = new JSONObject(loadJSONFromAsset(getContext())); 
    } catch (JSONException e) { 
     e.printStackTrace(); 
    } catch (IOException e) { 
     e.printStackTrace(); 
    } 
    ProteusLayoutInflater layoutInflater = (ProteusLayoutInflater)inflater; 
    ProteusView view = layoutInflater.inflate(jsonlayout.toString(), null, container, 0); 
    return view.getAsView(); 
}

我想用变形库创建一个视图，使其作为片段。

你能告诉我我做错了什么吗？有了这个代码，我发现了以下错误：

com.android.internal.policy.PhoneLayoutInflater cannot be cast to com.flipkart.android.proteus.ProteusLayoutInflater

回答：

下面是Fragment一些示例代码，应该让你开始：

remember to add gson-adapter to the build.gradle file of your app.

dependencies { compile 'com.github.flipkart-incubator.proteus:gson-adapter:5.0.0-rc12' }

在您的片段添加，并根据修改如下：

// some private fields in the fragment 
    private Proteus proteus; 
    private ProteusContext context; 
    private ProteusLayoutInflater layoutInflater; 
    private Gson gson; 
    public void onAttach (Activity activity) { 
    // create a new instance of the proteus type adapter 
    // for gson and register it with gson. 
    ProteusTypeAdapterFactory adapter = new ProteusTypeAdapterFactory(activity); 
    gson = new GsonBuilder().registerTypeAdapterFactory(adapter).create(); 
    // create a new instance of proteus from the builder 
    proteus = new ProteusBuilder().build(); 
    // get a new context object from proteus 
    context = proteus.createContextBuilder(activity).build(); 
    // this context object has the proteus layout inflater 
    layoutInflater = context.getInflater(); 
    // set the instance of proteus 
    ProteusTypeAdapterFactory.PROTEUS_INSTANCE_HOLDER.setProteus(proteus); 
    } 
    public ProteusContext getContext() { 
    return context; 
    } 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
    String layoutString = loadJSONFromAsset(getContext()); 
    // use gson to deserialize the string into a Layout object. 
    Layout layout = gson.fromJson(layoutString, Layout.class); 
    // the use the proteus layout inflater to inflate a new proteus view 
    ProteusView view = layoutInflater.inflate(layout, new ObjectValue()); 
    return view.getAsView(); 
    }
