  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：

    1. 我有点困惑它被带到前面意味着什么，以及整个事情

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
