最近一直有点忙,刚刚看到一个朋友的留言提到Fragment中加载ListView的问题,这里写了一个非常简单的测试,至于对Fragment的增、删、改实现动态布局构建灵活的UI,以后有时间在讨论:
MainActivity:
package com.home.testfragment; import java.util.ArrayList; import java.util.List; import android.os.Bundle; import android.support.v4.app.FragmentActivity; import android.widget.ArrayAdapter; import android.widget.ListView; public class MainActivity extends FragmentActivity { @Override protected void onCreate(Bundle arg0) { super.onCreate(arg0); setContentView(R.layout.main); ListView listView = (ListView) findViewById(R.id.fragment__first_list); List<String> list = new ArrayList<String>(); list.add("张三"); list.add("李四"); list.add("王五"); list.add("赵六"); ArrayAdapter<String> adapter = new ArrayAdapter(this, android.R.layout.simple_list_item_1, list); listView.setAdapter(adapter); } }
FirstFragment:
package com.home.testfragment; import android.os.Bundle; import android.support.v4.app.Fragment; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; public class FirstFragment extends Fragment { @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { return inflater.inflate(R.layout.fragment_first, container, false); } }
main.xml:
<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:name="com.home.testfragment.FirstFragment" android:layout_width="match_parent" android:layout_height="wrap_content" android:tag="@+id/main_fragment_first" /> </LinearLayout>
fragment_first:
<?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" > <TextView android:layout_width="match_parent" android:layout_height="wrap_content" android:text="测试fragment的简单使用" android:textSize="20sp" /> <ListView android:id="@+id/fragment__first_list" android:layout_width="match_parent" android:layout_height="wrap_content" > </ListView> </LinearLayout>
