无法解析构造函数 Intent

Question

• 我正在尝试向我的应用程序添加一个 tabhost，但我无法理解为什么会显示此错误 'cannot resolve constructor intent'，这是我的 activity 代码：

  public class SixthFragment extends Fragment {
  public static final String TAG = "sixth";
  
  
  
  @Nullable
  @Override
  public View onCreateView(LayoutInflater inflater, ViewGroup container,       Bundle   savedInstanceState) {
  
  View view =  inflater.inflate(R.layout.sixthfragment, container, false);
  TabHost tabHost = (TabHost) view.findViewById(R.id.tabHost);
  
  TabHost.TabSpec tab1 = tabHost.newTabSpec("First Tab");
  TabHost.TabSpec tab2 = tabHost.newTabSpec("Second Tab");
  TabHost.TabSpec tab3 = tabHost.newTabSpec("Third tab");
  
  // Set the Tab name and Activity
  // that will be opened when particular Tab will be selected
  tab1.setIndicator("Tab1");
  tab1.setContent(new Intent(this,MainActivity.class));
  
  tab2.setIndicator("Tab2");
  tab2.setContent(new Intent(this,Tab2Activity.class));
  
  tab3.setIndicator("Tab3");
  tab3.setContent(new Intent(this,Tab3Activity.class));
  
  /** Add the tabs  to the TabHost to display. */
  tabHost.addTab(tab1);
  tabHost.addTab(tab2);
  tabHost.addTab(tab3);
  
  
  return view;
  
  
  }
  
  
  @Override
  public void onActivityCreated(Bundle savedInstanceState) {
  super.onActivityCreated(savedInstanceState);
  
  }
  
  
  
  }
  

  感谢您的宝贵时间。

您尝试使用的 Intent 构造函数的第一个参数采用 Context。 Fragment 不是 Context。使用 getActivity() 而不是 this.
