项目点击的ID - Android的ContextMenu

G'day，
我有一个ListView填充各种文本值，我想要它，当你长按和打开上下文菜单，你可以复制文本在你长时间按下的ListItem。到目前为止，我已经得到了上下文菜单中的“复制”选项，弹出：项目点击的ID - Android的ContextMenu

public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) 
{ 
    //this was following another question but I don't know what to do with it 
    AdapterView.AdapterContextMenuInfo info = (AdapterView.AdapterContextMenuInfo) menuInfo; 
    long selectedId = info.id; 
    super.onCreateContextMenu(menu, v, menuInfo); 
    MenuInflater inflater = getMenuInflater(); 
    inflater.inflate(R.menu.context, menu); 
} 
public boolean onContextItemSelected(MenuItem item) 
{ 
    AdapterContextMenuInfo info = (AdapterContextMenuInfo) item.getMenuInfo(); 
    switch (item.getItemId()) 
    { 
    case R.id.copy: 
     //used to be in a function but wasn't sure about views 
     //yes I know it's depreciated but it works ;) 
     ClipboardManager clipboard = (ClipboardManager) getSystemService(CLIPBOARD_SERVICE); 
     TextView clicked = (TextView)this.findViewById(???); 
     clipboard.setText(clicked.getText()); 
     Context context = getApplicationContext(); 
     Toast copied = Toast.makeText(context, "Story copied to clipboard.", Toast.LENGTH_LONG); 
     copied.show(); 
     return true; 
    default: 
     return super.onContextItemSelected(item); 
    } 
}

感谢

你有什么问题吗？ –

@Chirag我不知道该把什么放在哪里？是。如果我可以传递该项目的ID长按，我可以做... findViewById（id）; – ProfSmiles

设置一个变量来保存被点击的观点：

View clicked;

然后在其上创建上下文菜单时值分配给它：

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

    //this was following another question but I don't know what to do with it 
    AdapterView.AdapterContextMenuInfo info = (AdapterView.AdapterContextMenuInfo) menuInfo; 
    long selectedId = info.id; 
    super.onCreateContextMenu(menu, v, menuInfo); 
    MenuInflater inflater = getMenuInflater(); 
    inflater.inflate(R.menu.context, menu); 
}

现在你可以使用它在你的最终满足hod：

public boolean onContextItemSelected(MenuItem item) 
{ 
    AdapterContextMenuInfo info = (AdapterContextMenuInfo) item.getMenuInfo(); 
    switch (item.getItemId()) 
    { 
    case R.id.copy: 
     //used to be in a function but wasn't sure about views 
     //yes I know it's depreciated but it works ;) 
     ClipboardManager clipboard = (ClipboardManager) getSystemService(CLIPBOARD_SERVICE); 

     clipboard.setText(clicked.getText()); 
     // this should work now properly. 

     Context context = getApplicationContext(); 
     Toast copied = Toast.makeText(context, "Story copied to clipboard.", Toast.LENGTH_LONG); 
     copied.show(); 
     return true; 
    default: 
     return super.onContextItemSelected(item); 
    } 
}

当我把它放进去时，Eclipse说这是一个错误，并提供将其更改为item.getTitle（），但是它只是将“复制”（我触摸的上下文菜单的标题）放入剪贴板，而我想要文本什么是ListItem我原本是长按 – ProfSmiles

对不起，我的坏。您可以在调用'onCreateContextMenu'时将适当的视图存储在一个变量中。我会编辑我的答案。 –

使用上面的代码，'clicked.getText（）'显然是一个错误：“方法getText（）未定义为类型View” – ProfSmiles

我想你已经回答了你自己的问题。该ID是：

long selectedId = info.id;
