getFragmentManager从ArrayAdapter [英] getFragmentManager from ArrayAdapter

问题描述

我从我的自定义ArrayAdapter溢满一个ListView。在每个视图有一个按钮。我想改变当前片段单击按钮时。这是我的code：

I have a listView fulled from my custom ArrayAdapter. In each view there is a button. I want to change the current fragment when the button is clicked. This is my code:

public class CheckInSArrayAdapter extends ArrayAdapter<JSONObject> {


    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        return getViewOptimize(position, convertView, parent);
    }

    public View getViewOptimize(int position, View convertView, ViewGroup parent) {

    ......

        viewHolder.commentBtn.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {

            ??? <<<<<

        });

        return convertView;
    }

    private class ViewHolder {
        ...       
        public Button commentBtn;
    }

}

所以，现在，我无法从OnClickListener调用getFragmentManager。我该怎么办？

So now, i can't invoke getFragmentManager from the OnClickListener. How can i do?

推荐答案

好吧，也许我有点晚了，但是，也许它会帮助一些人做到这一点。

OK, maybe i'm a bit late but, maybe it will help some people to do this.

在那里你调用了适配器类，则需要扩展或实施FragmentActivity。然后，你的活动将包含fragmentManager。

In the class where you call the adapter, you need to extends or implements "FragmentActivity". Then your Activity will contain a fragmentManager.

当你打电话给你适配器与扩展FragmentActivity类称之为

When you call your Adapter call it with the class that extends FragmentActivity

MyAdapterName = new MyAdapterName(MyClassName.this, Objects);

然后在getView适配器（） - 做到这一点

Then in your adapter in getView() - do this.

final Context context = parent.getContext();
FragmentManager fm = ((Activity) context).getFragmentManager();

要当心使用Android的好FragementManager
- android.app.FragmentManager
不android.support.v4.app.FragmentManager;

Be carefull to use the good android FragementManager - android.app.FragmentManager not android.support.v4.app.FragmentManager;
