Android 如何在自定义RecyclerView适配器中使用startActivity（intent）启动新活动？

我有一个CustomRecycleServiceAdapter.class文件，我在其中实现了以下方法

public void onBindViewHolder(RecyclerViewHolder viewHolder, int position)
{
    viewHolder.title.setText(mData.get(position).text);
    //viewHolder.icon.setBackgroundColor(Color.parseColor(mData.get(position).color));

    viewHolder.setClickListener(new RecyclerViewHolder.ClickListener(){

        @Override
        public void onClick(View v, int position, boolean isLongClick) {

            if (isLongClick) {
                // View v at position pos is long-clicked.
                Toast.makeText(v.getContext(), "Hey you just hit item" + position, Toast.LENGTH_SHORT).show();


            }else {
                // View v at position pos is clicked.
                //how to start a new activity here
                Toast.makeText(v.getContext(),"Hey you just hit item" + position,Toast.LENGTH_SHORT).show();
            }


        }
    });

}

那么我如何在上面的else块中启动新活动

集体课

public class Group extends ActionBarActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);//line no. 16 which is indicated in logcat
        setContentView(R.layout.group);

        getSupportActionBar().setHomeButtonEnabled(true);
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);

}

这是我的错误日志

谢谢您的时间。

您可以使用任何视图查看它。 getContext（）方法提供了几乎所有的活动方法，因为活动扩展了上下文

v.getContext().startActivity(intent);

---

那么，目前面临的问题是什么？只需使用

v.getContext（）.startActivity（intent）

点击按钮即可启动活动我使用了此代码intent intent=new intent（v.getContext（），Group.class）；v、 getContext（）.startActivity（意图）；但它在

AndroidManifest.xml

中不幸地添加了

Group.class

，停止了应用程序？如果是，那么共享崩溃日志我已经在menifest中添加了类，但我仍然收到了相同的问题，并且我已经用崩溃日志更新了帖子
