通過XML文件, 創建片段(Fragment)

前文"Android 3.0 新增的片段(Fragment)"的MyFragment.java類使用Java程序碼創建片段(Fragment). 本例修改MyFragment.java, 使用inflater類的inflate()方法, 通過XML文件, 創建片段(Fragment).



- 建立新的XML文件, /res/layout/fragment1.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
   android:layout_width="fill_parent"
   android:layout_height="fill_parent"
   android:orientation="vertical" >
   <TextView
       android:layout_width="match_parent"
       android:layout_height="wrap_content"
       android:text="FRAGMENT HERE" />
   <ImageView
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:src="@drawable/ic_launcher"/>
</LinearLayout>

- 修改MyFragment.java

package com.android3Frag;
import android.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;


public class MyFragment extends Fragment {

 @Override
 public View onCreateView(LayoutInflater inflater, ViewGroup container,
   Bundle savedInstanceState) {
  View view = inflater.inflate(R.layout.fragment1, container, false);
  
  return view;
 }

}

- 沿用前文的main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="horizontal" >

    <TextView
        android:layout_width="0px"
        android:layout_weight="2"
        android:layout_height="match_parent" 
        android:text="@string/hello"/>
    <fragment
        class="com.android3Frag.MyFragment"
        android:id="@+id/myfragment"
        android:layout_width="0px"
        android:layout_weight="3"
        android:layout_height="match_parent"/>

</LinearLayout>
