Question

我有3个标签，每个标签都有一个列表视图。我已经为上下文菜单注册了这些列表视图。我有三个不同的arraylists，我存储各个列表视图的项目。

现在我想要点击列表视图项目的位置。

我的代码是：

public boolean onContextItemSelected(MenuItem item) {

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

      switch(item.getItemId()){

   case R.id.mycards_contextmenu_1:

       if(mCurrentTab.equals("Tab 1")){
           try{
           int pos= info.position;
           Toast.makeText(getBaseContext(), pos, Toast.LENGTH_LONG).show();
           }catch(Exception e){
               Toast.makeText(getBaseContext(), e.toString(), Toast.LENGTH_LONG).show();
           }
           }
    break;

  }

我正在

   android.content.res.resources$notfoundexception

我哪里出错了？

Answer 1

Toast.makeText(getBaseContext(), pos, Toast.LENGTH_LONG).show();

应该是

Toast.makeText(getBaseContext(), String.valueOf(pos), Toast.LENGTH_LONG).show();

Toast还有一个makeText()方法，在String资源ID（int）中接受，并通过pasing pos调用该方法，找不到具有该id的String资源，因此

android.content.res.Resources$NotFoundException

得到“android.content.res.resources $ notfoundexception”
