一下是个人的一些总结。
为fragment创建XML
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent"> <ListView android:id="@+id/yulelist" android:layout_width="match_parent" android:layout_height="wrap_content"/> </LinearLayout>
public class Yule extends ListFragment { @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { return inflater.inflate(R.layout.yule,container,false); } //主要就是加载我们刚刚写好的fragment.xml布局文件并返回
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:baselineAligned="false" > <fragment android:id="@+id/fragment1" android:name="com.example.fragmentdemo.Fragment1" android:layout_width="0dip" android:layout_height="match_parent" android:layout_weight="1" /> <fragment android:id="@+id/fragment2" android:name="com.example.fragmentdemo.Fragment2" android:layout_width="0dip" android:layout_height="match_parent" android:layout_weight="1" /> </LinearLayout>
public class MainActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); //获取屏幕尺寸 Display display = getWindowManager().getDefaultDisplay(); if (display.getWidth() > display.getHeight()) { Fragment1 fragment1 = new Fragment1(); getFragmentManager().beginTransaction().replace(R.id.main_layout, fragment1).commit(); } else { Fragment2 fragment2 = new Fragment2(); getFragmentManager().beginTransaction().replace(R.id.main_layout, fragment2).commit(); } } }
