Fragment newFragment = new ExampleFragment(); FragmentTransaction transaction = getFragmentManager().beginTransaction(); // Replace whatever is in the fragment_container view with this fragment, // and add the transaction to the back stack
<fragment>中的android:name属性指定要在布局中进行实例化的 Fragment 类。 创建此 Activity 布局时,系统会将布局中指定的每个片段实例化,并为每个片段调用onCreateView()方法,以检索每个片段的布局。系统会直接插入片段返回的 View,从而代替<fragment>元素。
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" > ...
android:layout_height="match_parent"> <fragmentandroid:name="com.example.news.ArticleListFragment" android:id="@+id/list" android:layout_weight="1" android:layout_width="0dp" android:layout_height="match_parent"/> <fragmentandroid:name="com.example.news.ArticleReaderFragment" ...
