android-intent - 模拟器不会重新加载代码

Question

1. 这是我的代码

   public class MainActivity extends Activity {
   Button btn;
   
   public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.activity_main);
       btn = (Button) findViewById(R.id.button1);
       btn.setOnClickListener(new View.OnClickListener() {
           @Override
           public void onClick(View v) {
               Intent intent = new Intent(MainActivity.this,
                       socialnetworking.class);
               startActivity(intent);    
           }
       });    
   }    
   

   }

2. 但我从我的控制台收到这条消息：

       [2013-05-17 17:57:44 - NXTRemoteControl] ------------------------------
       [2013-05-17 17:57:44 - NXTRemoteControl] Android Launch!

   1. 我有点困惑它被带到前面意味着什么，以及整个事情

Answer 1

模拟器只是告诉你

1. 您的应用程序已经在“设备”上
2. 它无法检测到任何明显的变化
3. 它已经在运行，因此只需要把它带到最前面

如果您需要刷新它，您可以

• 卸载它并重新开始运行
• 更改它并再次开始运行它或
• 清理您的项目并再次开始运行它
