我使用ListFragment构建一个简单的应用程序,结构如下:
片段从ListFragment扩展
活动从FragmentActivity扩展
当前逻辑已定义:在MainActivity用户单击OneListFragment中的项目,启动DetailActivity,我需要将DetailActivity的附加内容传递给TwoListFragment,但我不知道如何?
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
final Cursor c = (Cursor) mAdapter.getItem(position);
final Intent intent = new Intent(getActivity(), DetailActivity.class);
intent.putExtra(KEY, c.getString(0));
startActivity(intent);
}
detail_activity.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<fragment
android:id="@+id/detailed_list"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
class="com.package.TwoListFragment" />
</LinearLayout>
答案 0 :(得分:3)
只需在ListActivity中使用putExtra,然后在TwoListFragment中使用getActivity()。getIntent()。get *** Extra()〜
