我們如何從片段啟動Activity

Question

Intent i = new Intent(this, ActivityTwo.class);
startActivity(i);

我想通過使用seOnClickListener從片段轉到Activity 。
上面的代碼不起作用

Answer 1

您應該使用：

Intent intent = new Intent(getActivity(), ActivityTwo.class);
getActivity().startActivity(intent)

Answer 2

Intent i = new Intent(FragmentName.this.getActivity(), ActivityTwo.class);
FragmentName.this.startActivity(i);

Answer 3

Intent i = new Intent(getActivity(), ActivityTwo.class);
 getActivity.startActivity(i);

Answer 4

In your fragment write below code.

private Activity mActivity;

@Override
    public void onAttach(Context context) {
        super.onAttach(context);
        mActivity = (Activity) context;
    }

and then call your activity

Intent intent = new Intent(mActivity, ActivityTwo.class);
mActivity.startActivity(intent);

this will work for you.
