使用片段活动创建的 ADT 空白活动 [英] ADT blank activity created with fragment activity

问题描述

我现在真的很困惑，因为每当我创建一个带有空白活动的新 Android 应用程序时，它总是会出现 fragment_main.xml.我只想创建一个没有片段的空白活动.

I am really confused right now because whenever I create a new Android app with blank activity it always comes out with fragment_main.xml. I just wanted to create a blank activity without the fragment one.

在第一张图片中，空白活动带有片段布局:

In the first image the blank activity comes with the fragment layout:

第二张图显示了创建的fragment_main

The second image shows the created fragment_main

现在我真的很困惑……这只是在将 ADT 更新到最新版本后才发生的.我提到了这个线程:Adt不创建默认的 hello world 但命令行会_

Now I am really confused... this only happened after updating ADT to the latest version. I have referred to this thread: Adt doesn't create default hello world but command line does_

我只是想制作一个没有片段视图的空白 Activity 的 Android 应用.

I just wanted to make an Android app with blank activity with no fragment view.

推荐答案

对于那些想了解如何从项目中删除 Fragment 的人:

For those who would like instructions on how to remove Fragments from the project:

1) 复制 res/layout/fragment_main.xml 的所有内容.打开activity_main.xml，删除FrameLayout，粘贴复制的内容.

1) Copy all the contents of res/layout/fragment_main.xml. Open activity_main.xml, delete the FrameLayout, and paste in the copied contents.

2) 删除fragment_main.xml

2) Delete fragment_main.xml

3) 在 MainActivity.java 中，删除整个 PlaceHolderFragment 类:

3) In MainActivity.java, delete the whole PlaceHolderFragment class:

/**
 * A placeholder fragment containing a simple view.
 */
public static class PlaceholderFragment extends Fragment {

    public PlaceholderFragment() {
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                    Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.fragment_main,
                    container, false);
        return rootView;
    }
}

4) 从 onCreate() 中删除以下几行:

4) Delete the following lines from onCreate():

if (savedInstanceState == null) {
    getSupportFragmentManager().beginTransaction()
            .add(R.id.container, new PlaceholderFragment()).commit();
}

此时您应该已准备好运行项目.

At this point you should be all set to run the project.
