程序排错

以下为原代码：

import com.avos.avoscloud.AVUser;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.os.Handler;

public class WelcomeActivity extends Activity {

   Handler handler = new Handler();

   Runnable runnable = new Runnable() {

      public void run() {
         Intent intent = new Intent(WelcomeActivity.this, LoginActivity.class);
         startActivity(intent);
         finish();

      }

   };
   
   Runnable runnable1 = new Runnable() {

      public void run() {
         Intent intent = new Intent(WelcomeActivity.this, MainActivity.class);
         startActivity(intent);
         finish();

      }

   };

   @Override
   protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_welcome);
      AVUser currentUser = AVUser.getCurrentUser();
   
        if (currentUser != null) {
            // 跳转到首页
           handler.postDelayed(runnable1, 2000);
        } else {
            //缓存用户对象为空时，可打开用户注册界面…
           handler.postDelayed(runnable, 2000);
        }

   }
}

经过测试，发现if 语句使用不对，应该有else语句

 TODO Auto-generated method stub太多,执行起来会有提示
