StartActivity 工具类_startactivity工具-优快云博客

本文介绍了一个用于简化Android应用中界面跳转的实用工具类。通过该工具类，开发者可以轻松实现不同活动之间的跳转，包括携带参数的跳转及带有回调结果的跳转。这有助于减少重复代码，提高开发效率。

每个项目中都会有界面的跳转，为了使用方便，我们可以将其封装一下，可以相应的减少代码量，直接上代码

public class JumperUtils {
   public static void JumpTo(Activity activity, Class<?> cls) {
      try {
         Intent intent = new Intent(activity, cls);
         activity.startActivity(intent);
      } catch (ActivityNotFoundException e) {
         e.printStackTrace();
      } catch (NullPointerException e) {
         e.printStackTrace();
      }        
   }
   
   
   public static void JumpTo(Activity activity, Class<?> cls, Bundle bundle) {
      try {
         Intent intent = new Intent(activity, cls);
         intent.putExtras(bundle);
         activity.startActivity(intent);
      } catch (ActivityNotFoundException e) {
         e.printStackTrace();
      } catch (NullPointerException e) {
         e.printStackTrace();
      }        
   }
   
   /**
    * startActivityForResult，跳�?
    * @param activity
    * @param cls
    * @param bundle
    * @param requestCode
    */
   public static void JumpToForResult(Activity activity, Class<?> cls, Bundle bundle, int requestCode) {
      try {
         Intent intent = new Intent(activity, cls);
         intent.putExtras(bundle);
         activity.startActivityForResult(intent,requestCode);
      } catch (ActivityNotFoundException e) {
         e.printStackTrace();
      } catch (NullPointerException e) {
         e.printStackTrace();
      }        
   }
   
   /**
    * startActivityForResult，跳�?
    * @param activity
    * @param cls
    * @parambundle
    * @param requestCode
    */
   public static void JumpToForResult(Activity activity, Class<?> cls, int requestCode) {
      try {
         Intent intent = new Intent(activity, cls);
         activity.startActivityForResult(intent,requestCode);
      } catch (ActivityNotFoundException e) {
         e.printStackTrace();
      } catch (NullPointerException e) {

      }        
   }
}
