将参数传递给 DialogFragment [英] passing argument to DialogFragment

问题描述

我需要将一些变量传递给 DialogFragment，以便我可以执行操作.Eclipse 建议我应该使用

I need to pass some variables to DialogFragment, so I can perform an action. Eclipse suggests that I should use

Fragment#setArguments(Bundle)

但是我不知道如何使用这个功能.我如何使用它来将变量传递给我的对话框?

But I don't know how to use this function. How can I use it to pass variables to my dialog?

推荐答案

Using newInstance

public static MyDialogFragment newInstance(int num) {
    MyDialogFragment f = new MyDialogFragment();

    // Supply num input as an argument.
    Bundle args = new Bundle();
    args.putInt("num", num);
    f.setArguments(args);

    return f;
}

并像这样获得 Args

And get the Args like this

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    mNum = getArguments().getInt("num");
    ...
}
