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

Question

我有3个标签，每个标签都有一个listview。 我已经为上下文菜单注册了这些listviews。 我有三个不同的arraylists，其中分别存储了各个listview的项目。

现在我想要单击的listview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;

  } 

我正进入（状态

   android.content.res.resources$notfoundexception

我哪里出问题了？

Answer 1

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

应该

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

Toast还具有一个makeText()方法，该方法接受一个String资源ID（一个int ），并且通过pos调用该方法，该方法无法找到具有该ID的String资源，因此

android.content.res.Resources$NotFoundException
