我有一个字符串输入,其中包含一个带字符串Fromat的Layout.xml。

 // String that contains the Layout.xml :

 String concat ;

 // Create the XmlPullParser from the String format

 XmlPullParserFactory factory = XmlPullParserFactory.newInstance();

 factory.setNamespaceAware(true);

 XmlPullParser xpp = factory.newPullParser();
 xpp.setInput( new StringReader (concat) ); 

 // create le The LayoutInflater 

 LayoutInflater inflater =         (LayoutInflater)this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

 View myView = inflater.inflate(xpp, null);

我有这个错误:

  

03-12 08:23:12.876:W / System.err(937):android.view.InflateException:   START_TAG http://schemas.android.com/apk/res/android}android:orientation='vertical'   {http://schemas.android.com/apk/res/android}机器人:layout_width = 'FILL_PARENT'   {http://schemas.android.com/apk/res/android}机器人:layout_height = 'FILL_PARENT' > @ 1:226   在java.io.StringReader@44f50508中:错误膨胀类

请帮忙吗?

似乎Inflater只接受XmlBlock。

我已经编写了一个方法来执行此操作,您可以参考项目站点: https://github.com/liudongmiao/preference-fragment-compat/blob/master/src/me/piebridge/android/preference/PreferenceFragment.java#L202

主要代码如下:

// byte[] data = ... 
// bytes of compiled xml (unzip the apk, get the bytes from res/layout*/*.xml)

// XmlBlock block = new XmlBlock(data);
Class<?> clazz = Class.forName("android.content.res.XmlBlock");
Constructor<?> constructor = clazz.getDeclaredConstructor(byte[].class);
constructor.setAccessible(true);
Object block = constructor.newInstance(data);

// XmlPullParser parser = block.newParser();
Method method = clazz.getDeclaredMethod("newParser");
method.setAccessible(true);
XmlPullParser parser = method.invoke(block);
