Class ViewTypeDetector

java.lang.Object

com.android.tools.lint.detector.api.Detector

com.android.tools.lint.detector.api.ResourceXmlDetector

com.android.tools.lint.checks.ViewTypeDetector

All Implemented Interfaces:

com.android.tools.lint.detector.api.FileScanner, com.android.tools.lint.detector.api.SourceCodeScanner, com.android.tools.lint.detector.api.XmlScanner, com.android.tools.lint.detector.api.XmlScannerConstants

public class ViewTypeDetector
extends com.android.tools.lint.detector.api.ResourceXmlDetector
implements com.android.tools.lint.detector.api.SourceCodeScanner

Detector for finding inconsistent usage of views and casts

TODO: Check findFragmentById

 ((ItemListFragment) getSupportFragmentManager()
   .findFragmentById(R.id.item_list))
   .setActivateOnItemClick(true);
 

Here we should check the <fragment> tag pointed to by the id, and check its name or class attributes to make sure the cast is compatible with the named fragment class!
