Surface View 和线性布局以及 onClick 事件

Question

我在将表面视图添加到线性布局时遇到问题，我已经尝试了已经可用的答案，但似乎仍然无法弄清楚。我的目标是在单击下一步按钮时在登录屏幕底部呈现动画。我尝试向屏幕添加一个线性布局，然后将我的 gameView 对象添加到它上面。

这是 loginActivity 和游戏视图 Class 为了清楚起见，我还添加了 xml。

Answer 1

您还没有将 myLayout 附加到您之前在 setContentView(R.layout.main) 上设置的 activity 主布局。

而不是：

 LinearLayout myLayout = new LinearLayout(this);
 myLayout.findViewById(R.id.gameLayoutView);
 myLayout.addView(gameView);

你应该这样写：

LinearLayout myLayout = (LinearLayout) findViewById(R.id.gameLayoutView);
myLayout.addView(gameView);
