Question

我有一个问题：我可以使用在另一个方法中的方法中实例化的内部类变量吗？

 public void onItemClick(AdapterView<?> a, android.view.View v, int position, long id) {
            // TODO Auto-generated method stub
            int diffInDays=0;
            Object o = lv1.getItemAtPosition(position);
            Masina m = (Masina) o;
            Toast.makeText(MainActivity.this, "Selected :" + " " + m, Toast.LENGTH_LONG).show();
            String data=((Masina) image_details.get(position)).getData_fabr();
            Calendar c=Calendar.getInstance();
             SimpleDateFormat df=new SimpleDateFormat("dd/MM/yyyy");
             String currData=df.format(c.getTime());

             try {

                 Date obj=df.parse(data);
                 Date obj2=df.parse(currData);
                 diffInDays = (int) ((obj2.getTime() - obj.getTime())/ (1000 * 60 * 60 * 24));

             } catch (ParseException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

             int years=diffInDays/365;
             int days=diffInDays%365;
             poz=position; 

             mar=((Masina) image_details.get(poz)).getMarca();
             mod=((Masina) image_details.get(poz)).getModel();
             nr=((Masina) image_details.get(poz)).getNr_inm();
             date=((Masina) image_details.get(poz)).getData_fabr();

             afisare.setText("Numar inmatriculare: "+((Masina) image_details.get(position)).getNr_inm());
             afisare.append("\nVarsta masina: "+years+" ani "+days+" zile");

        }
    });


}

public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) {

    super.onCreateContextMenu(menu, v, menuInfo);
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.context_menu, menu);

}

public boolean onContextItemSelected(MenuItem item) {

    AdapterContextMenuInfo info = (AdapterContextMenuInfo) item.getMenuInfo();

    switch(item.getItemId()) {

    case R.id.edit:

        Toast.makeText(this, "Ai ales: " + getResources().getString(R.string.Editeaza), Toast.LENGTH_SHORT).show();
            Intent startNewAct=new Intent(MainActivity.this, EditActivity.class);
            startNewAct.putExtra("marca",mar);
            startNewAct.putExtra("model",mod);
            startNewAct.putExtra("Nr.inm",nr);
            startNewAct.putExtra("Data",date);
            startActivityForResult(startNewAct,0); 


            return true;

我想在方法onContextItemSelected中使用vb mar。请帮帮忙。非常感谢你。

你可以用方法中的public static初始化vb mar。

我可以在我的方法中使用内部类变量吗？
