片段+滑动+抽屉菜单

标签： android android-fragments android-studio

我意识到我的＆＃34;刷卡＆＃34;两个有效的片段之间的项目。我的项目还有我的步行抽屉菜单。我尝试链接这两个但是遵循这个包含我的MainActivity的汇编代码，我的菜单必须成为/作为一个片段。这么多功能改变了语言/写作。

there a easy idea of my plan

这是我的代码MainActivity：

MY ERRORS

如何更改setContentView / getApplicationContext / findViewById ...等以适应片段？

我是否必须使用片段进行处理才能实现这个小小的蒙太奇（见图1）？片段看起来很实用，以后我无论如何都非常有用......

谢谢;）

尝试使用getActivity（）。function_name（），即您在片段中提到的问题。但这不是正确的方法。您可以按照此处给出的说明进行操作，以获得抽屉布局。

错误是：

there

因为我不使用“fragment”作为我的toolbarmenu / drawermenu它不能工作。 我应该尝试将菜单分离为另一个类，然后在片段中调用它。但是如何？...;）

答案 2 :(得分：-1)

您的 MainActivty 正在通过 AppCompactActivity 扩展片段替换片段。并删除放置在类底部的 onCreateView 方法，不需要该方法。如果您需要以下代码行：

((TextView)MainActivity.findViewById(R.id.textView)).setText("iOS");

onCreateView 方法中提到

，然后您可以将此行代码移至 onCreate 方法。但是你必须在 onCreate 方法中写如下：

((TextView)findViewById(R.id.textView)).setText("iOS");

onCreateView 方法无需其他任何代码行，因此请删除该方法。
