如何从OnClickListener调用片段 [英] How to call Fragment from OnClickListener

问题描述

我的工作片段。我想从onClickListener调用一个片段。
    我该怎么办呢？这是我的code。从其他的部分我要的一个电话fragment..how这样做呢？

  chartView.setOnClickListener（新View.OnClickListener（）{
            @覆盖
            公共无效的onClick（视图v）{
                SeriesSelection seriesSelection = chartView
                        .getCurrentSeriesAndPoint（）;                如果（seriesSelection == NULL）{
                    Toast.makeText（getActivity（）。getApplicationContext（），
                            没有图表元素被点击了
                            Toast.LENGTH_SHORT）.show（）;
                }其他{
                    Toast.makeText（
                            getActivity（）。getApplicationContext（），
                            图元数据点指数
                                    +（seriesSelection.getPointIndex（）+1）
                                    +被点击+点值=
                                    + seriesSelection.getValue（），
                            Toast.LENGTH_SHORT）.show（）;
                }
            }
        }）;
 

解决方案

有很多方法可以代替片段。
但是我遵循以下方式：

在

创建addFragmentMethod（）之类

 公共无效addFragments（片段片段）{
    FragmentManager经理= getSupportFragmentManager（）;
    FragmentTransaction英尺= manager.beginTransaction（）;
    ft.replace（android.R.id.tabcontent，片段）;
    ft.commit（）;
}
 

现在覆盖onAttach（）这样的

  @覆盖
公共无效onAttach（活动活动）{
    this.activity =（YourActivity）活性;
    myDetail = this.activity.myDetail;
    super.onAttach（活动）;
    }
 

现在只需拨打

  activity.addFragments（片段）;
 

I am working in Fragment. i want to call one fragment from onClickListener. how can i do that? This is my code. from the else part i have to call one fragment..how to do that?

  chartView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                SeriesSelection seriesSelection = chartView
                        .getCurrentSeriesAndPoint();

                if (seriesSelection == null) {
                    Toast.makeText(getActivity().getApplicationContext(),
                            "No chart element was clicked",
                            Toast.LENGTH_SHORT).show();
                } else {
                    Toast.makeText(
                            getActivity().getApplicationContext(),
                            "Chart element data point index "
                                    + (seriesSelection.getPointIndex() + 1)
                                    + " was clicked" + " point value="
                                    + seriesSelection.getValue(),
                            Toast.LENGTH_SHORT).show();


                }
            }
        });

解决方案

There are many ways to replacing Fragments. but I follow the way below:

Create addFragmentMethod() like below

 public void addFragments(Fragment fragment) {
    FragmentManager manager = getSupportFragmentManager();
    FragmentTransaction ft = manager.beginTransaction();
    ft.replace(android.R.id.tabcontent, fragment);
    ft.commit();
}

now override onAttach() like this

@Override
public void onAttach(Activity activity) {
    this.activity = (YourActivity) activity;
    myDetail = this.activity.myDetail;
    super.onAttach(activity);
    }

now just call

activity.addFragments(fragment);
