Android-找不到片段类

Question

public void onResponse(JSONObject response) {
            Log.d(TAG, response.toString());

            try {
                Boolean status = response.getBoolean("responce");
                if (status) {
                    String msg = response.getString("data");
                    String msg_arb=response.getString("data");
                    db_cart.clearCart();
                    Bundle args = new Bundle();
                    Fragment fm = new Thanks_fragment();
                    args.putString("msg", msg);
                    args.putString("msgarb",msg_arb);
                    fm.setArguments(args);
                    FragmentManager fragmentManager = getFragmentManager();
                    fragmentManager.beginTransaction().replace(R.id.contentPanel, fm)
                            .addToBackStack(null).commit();
                }
            } catch (JSONException e) {
                e.printStackTrace();
            }

Fragment fm = new Thanks_fragment();

这部分代码无法识别Thanks_fragment();

我的班级PaymentGatWay extends Activity{

项目结构类似

• java
  • 片段
    • Thanks_fragment
  • 活动
    • PaymentGatWay

Thanks_fragment类

public class Thanks_fragment extends Fragment implements View.OnClickListener {

    TextView tv_info;
    RelativeLayout btn_home, btn_order;

    SharedPreferences preferences;

    String language;
    public Thanks_fragment() {
    }

有时会在android studio中发生。

转到->文件->使高速缓存无效/重新启动->使无效并重新启动

这将解决您的问题
