--布局文件嵌入: 在布局文件中 使用 <Fragment /> 元素, 通过定义android:name = "com.example.MyFragment"属性指定 Fragment 类; --代码方式嵌入: 调用 FragmentTransaction 对象的 add() 方法向 Activity 中添加 Fragment; 4. Fragment 与 Activity 通信 Fra

第一步:新建项目FragmentStudy,AndroidManifest.xml例如以下: <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.fragmentstudy" android:versionCode="1" android:versionName="1.0" > ...
<fragmentandroid:name="com.example.test.ExampleFragment"android:id="@+id/example_fragment"android:layout_width="wrap_content"android:layout_height="wrap_content"/> 也可以在代码中将Fragment加入已存在的ViewGroup中 FragmentManager fragmentManager =getFragmentManager(); ...
ExampleFragmentfragment=newExampleFragment();fragmentTransaction.add(R.id.fragment_container,fragment);fragmentTransaction.commit(); 传递到add()的第一个参数是 ViewGroup,即应放置片段的位置,由资源 ID 指定,第二个参数是要添加的片段。 一旦通过 FragmentTransaction 做出了更改,就必须调用commit()以使更改生效...

In our example, if we call setFragmentResult in AddNoteFragment more than once the system will send the most recent result to NoteListFragment before the AddNoteFragment is popped off the back stack.If the AddNoteFragment happens to be a child Fragment of the NoteListFragment. We just need...
Fragment newFragment = new ExampleFragment(); FragmentTransaction transaction=getFragmentManager().beginTransaction(); //Replace whatever is in the fragment_container view with thisfragment, //and add the transaction to the backstack transaction.replace(R.id.fragment_container,newFragment); ...
