我为片段事务使用以下布局。我正在使用以下代码替换片段1 与新片段。我附加布局文件也供您参考。我为每个listitem点击执行下面的代码。Android片段替换问题
代码:
Fragment newFragment = new Grades();
android.app.FragmentTransaction transaction = getFragmentManager().beginTransaction();
// Replace whatever is in the fragment_container view with this fragment
transaction.replace(R.id.fragment1, newFragment);
// Commit the transaction
transaction.commit();
Fragment newFragment = new Teachers();
android.app.FragmentTransaction transaction = getFragmentManager().beginTransaction();
// Replace whatever is in the fragment_container view with this fragment
transaction.replace(R.id.fragment1, newFragment);
// Commit the transaction
transaction.commit();
<LinearLayout
android:id="@+id/slidingPanel"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="left"
android:orientation="vertical"
android:background="@android:color/white"
>
<fragment
android:id="@+id/fragment1"
android:name="com.example.slideoutmenu.Item3"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</Linearlayout>
我怀疑是我应该更换片段1每次当我展现出新的片段或者我应该取代现有的片段,如果这样我怎么能取代现有的片段。
