Question

您好我试图显示android.view包中存在的所有类包在jar文件中。这将通过java反射concept.how进行访问
该类和我想在Android列表视图中显示任何人都可以帮助我..“

这是我的Display class_list.java文件

    public static void main(){
        List<ClassLoader> classLoadersList = new LinkedList<ClassLoader>();
        classLoadersList.add(ClasspathHelper.getContextClassLoader());
        classLoadersList.add(ClasspathHelper.getStaticClassLoader());
        // Reflections reflections1 = new Reflections("Doc");

         Reflections reflections = new Reflections(new ConfigurationBuilder()
            .setScanners(new SubTypesScanner(), new ResourcesScanner())
            .setUrls(ClasspathHelper.forClassLoader(classLoadersList.toArray(new ClassLoader[0])))
            .filterInputsBy(new FilterBuilder().include(FilterBuilder.prefix("android.view"))));


        Set<Class<?>> classes = reflections.getSubTypesOf(Object.class);
        //System.out.println(classes);
            Log.i("Ram","class name "+ classes);
        Iterator it=classes.iterator();
        while(it.hasNext()){
            Class c=(Class) it.next();
            int i;
            String classname = c.getName();
            Displayclass.your_array_list3.add(classname);

            Log.i("Ram","class name "+ c.getName());

        }
    }


}

这是我的活动档案

    public class Displayclass extends Activity {

    public static ArrayList<String> your_array_list3 = new ArrayList<String>();
    Intent StartLsit;
    private Displayclass  dl;
    @Override
    protected void onPostCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onPostCreate(savedInstanceState);
        setContentView(R.layout.displayclass);
        Button  class_button =(Button)findViewById(R.id.classbutton2);
        class_button.setOnClickListener(new OnClickListener() { 
            @Override

    public void onClick(View v) {
                 Intent clIntent = new Intent (v.getContext(),Displayclass_list.class);
                v.getContext().startActivity(clIntent);
                }
            });}
    public void doclass(View v) 
    {
        Log.i("send","I am in send function");
        StartLsit = new Intent(Displayclass.this,Displayclass_list.class);
        startActivity(StartLsit);
    }                                           
    @Override

    protected void onDestroy() {
        // TODO Auto-generated method stub
        super.onDestroy();
    }

    @Override
    protected void onPause() {
        // TODO Auto-generated method stub
        super.onPause();
    }

    @Override
    protected void onRestart() {
        // TODO Auto-generated method stub
        super.onRestart();
    }

    @Override
    protected void onResume() {
        // TODO Auto-generated method stub
        super.onResume();
    }

    @Override
    protected void onStart() {
        // TODO Auto-generated method stub
        super.onStart();


        ArrayAdapter<String> arrayAdapter3 = new ArrayAdapter<String>(this,
                android.R.layout.simple_list_item_1, your_array_list3 );
                dl.setAdapter(arrayAdapter3); 
                 try {
                  DisplayM.main();
                } catch (Exception e) {
                    e.printStackTrace();
                }
                // if (ViewClass.theEnd)
                // your_array_list.add(ViewClass.methods);  
            int lst = 0;
            for(int  i=0; i<lst; i++)
            {
            }

            }






    private void setAdapter(ArrayAdapter<String> arrayAdapter3) {
        // TODO Auto-generated method stub

    }
    @Override
    protected void onStop() {
        // TODO Auto-generated method stub
        super.onStop();

    }

}
