单击的项目的ID-Android ContextMenu

Question

G'day，
我有一个用各种文本值填充的ListView，并且我想让它在长按并打开上下文菜单时可以将文本复制到长按的ListItem中。 到目前为止，我已经弹出带有“复制”选项的上下文菜单：

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);
    }
}

谢谢

Answer 1

我认为您已经回答了自己的问题。 ID为：

long selectedId = info.id;

Answer 2

设置一个变量来保存被单击的视图：

View clicked;

然后在其上创建上下文菜单时为其分配一个值：

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，您可以在最终方法中使用它：

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);
    }
}
