如何调用从BaseAdapter类Android的片段？ [英] How to call a fragment from BaseAdapter Class Android?

问题描述

我想从我的BaseAdapter类叫Fragement。在这个类我有点击，而我想打电话给新片段按钮，但我不能够得到这一点。我必须从按钮到片段点击传递值。

BaseAdapter类

 公共类StatusAdapter扩展了BaseAdapter {

    私人活动的活动;
    私人的ArrayList＆LT; HashMap的＆LT;字符串，字符串＆GT;＆GT;数据;
    私有静态LayoutInflater吹气= NULL;
    公共StatusAdapter（活动一，
            ArrayList的＆LT; HashMap的＆LT;字符串，字符串＆GT;＆GT; D）{
        活性= A;
        数据= D;
        充气=（LayoutInflater）活动
                .getSystemService（Context.LAYOUT_INFLATER_SERVICE）;
    }

    @覆盖
    公众诠释getCount将（）{
        // TODO自动生成方法存根
        返回data.size（）;
    }

    @覆盖
    公共对象的getItem（INT位置）{
        // TODO自动生成方法存根
        返回的位置;
    }

    @覆盖
    众长getItemId（INT位置）{
        // TODO自动生成方法存根
        返回的位置;
    }

    @覆盖
    公共查看getView（INT位置，查看convertView，ViewGroup中父）{
        查看VI = convertView;
        如果（convertView == NULL）
            VI = inflater.inflate（R.layout.approval_selftrip_inner，NULL）;
        TextView的approved_by =（TextView中）vi.findViewById（R.id.approved_by）;
        TextView的状态=（TextView中）vi.findViewById（R.id.status）;
        TextView的行程=（TextView中）vi.findViewById（R.id.trip）;
        按钮view_log =（按钮）vi.findViewById（R.id.view_log）;

        HashMap的＆LT;字符串，字符串＆GT;名单=新的HashMap＆LT;字符串，字符串＆GT;（）;
        表= data.get（位置）;
        approved_by.setText（list.get（first_id））;
        status.setText（list.get（状态））;
        trip.setText（list.get（旅行））;
        view_log.setOnClickListener（新OnClickListener（）{
            @覆盖
            公共无效的onClick（视图v）{

                //在这里，我想打电话给我的片段

            }
        }）;
        返回六;
    }
}
 

Fragement

 公共类日志扩展片段{
    上下文语境;
    查看rootView;

    @覆盖
    公共查看onCreateView（LayoutInflater充气，容器的ViewGroup，
            捆绑savedInstanceState）{
        上下文= getActivity（）;

        rootView = inflater.inflate（R.layout.activity_log，
                集装箱，假）;
        返回rootView;
    }


}
 

我要调用该片段从BaseAdapter类上点击 view_log 的。请帮助我如何才能做到这一点。

在马丁Cazares 我已经这样做了。

在活动

 公开查看onCreateView（LayoutInflater充气，容器的ViewGroup，
            捆绑savedInstanceState）{
    上下文= getActivity（）;
        rootView = inflater.inflate（R.layout.activity_main，
                集装箱，假）;
        mBroadcastReceiver =新的BroadcastReceiver（）{
            @覆盖
            公共无效的onReceive（上下文的背景下，意图意图）{
                Toast.makeText（上下文中，Recived，
                           Toast.LENGTH_LONG）.show（）;
                ApprovalLog fragment2 =新ApprovalLog（）;
                FragmentManager fragmentManager = getFragmentManager（）;
                FragmentTransaction fragmentTransaction = fragmentManager
                        .beginTransaction（）;
                fragmentTransaction.replace（R.id.content_frame，fragment2）;
                fragmentTransaction.commit（）;
            }
        };
        返回rootView;
    }
 

在 AdapterClass

  view_approvallog.setOnClickListener（新OnClickListener（）{
            @覆盖
            公共无效的onClick（视图v）{
                CommonUtils.showAlert（测试适配器，活动）;
                activity.registerReceiver（mBroadcastReceiver，新的IntentFilter（
                        start.fragment.action））;

            }
        }）;
 

解决方案

只需使用此。

 公共无效的onClick（视图查看）{
 LogFrag fragment2 =新LogFrag（）;
 FragmentManager fragmentManager = getFragmentManager（）;
 FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction（）;
 fragmentTransaction.replace（R.id.fragment1，fragment2）;
 fragmentTransaction.commit（）;
}
 

I want to call a Fragement from my BaseAdapter Class. In this class I have button on click of which I want to call the new fragment, but I am not able to get this. I have to pass values from the click of the button to the fragment.

BaseAdapter Class

public class StatusAdapter extends BaseAdapter {

    private Activity activity;
    private ArrayList<HashMap<String, String>> data;
    private static LayoutInflater inflater = null;
    public StatusAdapter(Activity a,
            ArrayList<HashMap<String, String>> d) {
        activity = a;
        data = d;
        inflater = (LayoutInflater) activity
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    }

    @Override
    public int getCount() {
        // TODO Auto-generated method stub
        return data.size();
    }

    @Override
    public Object getItem(int position) {
        // TODO Auto-generated method stub
        return position;
    }

    @Override
    public long getItemId(int position) {
        // TODO Auto-generated method stub
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        View vi = convertView;
        if (convertView == null)
            vi = inflater.inflate(R.layout.approval_selftrip_inner, null);
        TextView approved_by = (TextView) vi.findViewById(R.id.approved_by);
        TextView status = (TextView) vi.findViewById(R.id.status);
        TextView trip = (TextView) vi.findViewById(R.id.trip);
        Button view_log = (Button)vi.findViewById(R.id.view_log);

        HashMap<String, String> list = new HashMap<String, String>();
        list = data.get(position);
        approved_by.setText(list.get("first_id"));
        status.setText(list.get("status"));
        trip.setText(list.get("trip"));
        view_log.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {

                //Here i want to call my fragment 

            }
        });
        return vi;
    }
}

Fragement

public class Log extends Fragment {
    Context context ;
    View rootView;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        context = getActivity();

        rootView = inflater.inflate(R.layout.activity_log,
                container, false);
        return rootView;
    }


}

I want to call this Fragment from the BaseAdapter Class on click of view_log.Please help me how can we do this

After Martin Cazares I have done this

In Activity

public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
    context = getActivity();
        rootView = inflater.inflate(R.layout.activity_main,
                container, false);
        mBroadcastReceiver = new BroadcastReceiver() {
            @Override
            public void onReceive(Context context, Intent intent) {
                Toast.makeText(context, "Recived", 
                           Toast.LENGTH_LONG).show();
                ApprovalLog fragment2 = new ApprovalLog();
                FragmentManager fragmentManager = getFragmentManager();
                FragmentTransaction fragmentTransaction = fragmentManager
                        .beginTransaction();
                fragmentTransaction.replace(R.id.content_frame, fragment2);
                fragmentTransaction.commit();
            }
        };
        return rootView;
    } 

In The AdapterClass

view_approvallog.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                CommonUtils.showAlert("Test in Adapter", activity);
                activity.registerReceiver(mBroadcastReceiver, new IntentFilter(
                        "start.fragment.action"));

            }
        });

解决方案

Simply use this.

public void onClick(View view) {
 LogFrag fragment2 = new LogFrag();
 FragmentManager fragmentManager = getFragmentManager();
 FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
 fragmentTransaction.replace(R.id.fragment1, fragment2);
 fragmentTransaction.commit();
}
