我几天来一直在努力使用Android 3.0 SDK的片段概念,并且认为我会尝试使用StackOverflow ….

我有一个简单的(概念证明)应用程序：

这是我的主要布局：

<?xml version="1.0" enCoding="utf-8"?><relativeLayout  xmlns:androID="http://schemas.androID.com/apk/res/androID"  androID:layout_wIDth="match_parent"  androID:layout_height="match_parent">    <relativeLayout androID:ID="@+ID/relativeLayout1" androID:layout_alignParentBottom="true" androID:layout_wIDth="match_parent" androID:layout_height="200dp"><fragment androID:name="com.owentech.simplefragmentswap.staticfragment"            androID:ID="@+ID/fragment1" androID:layout_weight="1"            androID:layout_height="wrap_content" androID:layout_wIDth="fill_parent"/></relativeLayout><FrameLayout androID:ID="@+ID/frameLayout1" androID:layout_height="wrap_content"      androID:layout_alignParenttop="true" androID:layout_wIDth="match_parent"    androID:layout_above="@+ID/relativeLayout1"></FrameLayout></relativeLayout>

我直接在XML中显示一个片段(staticfragment),这很好用.

使用framelayout我想在create上添加一个XML片段(fragment1).

这是片段1：

<?xml version="1.0" enCoding="utf-8"?><relativeLayout  xmlns:androID="http://schemas.androID.com/apk/res/androID"  androID:layout_wIDth="match_parent"  androID:layout_height="match_parent">  <button androID:layout_height="wrap_content" androID:ID="@+ID/button1" androID:layout_alignParenttop="true" androID:layout_wIDth="match_parent" androID:text="Fragment 1"></button></relativeLayout>

这是我的主要活动：

import androID.app.Activity;import androID.os.Bundle;import androID.support.v4.app.Fragment;import androID.support.v4.app.FragmentActivity;import androID.support.v4.app.FragmentTransaction;public class mainActivity extends FragmentActivity {/** Called when the activity is first created. */@OverrIDepublic voID onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentVIEw(R.layout.main); // Create new fragment and transaction    Fragment newFragment = new fragment1();    FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();    // Replace whatever is in the fragment_container vIEw with this fragment,    // and add the transaction to the back stack    //transaction.replace(R.ID.frameLayout1, newFragment);    transaction.add(R.ID.frameLayout1, newFragment);    transaction.addToBackStack(null);    // Commit the transaction    transaction.commit();}}

这会导致力在启动时关闭.

这是logcat：

有没有人知道我做错了什么,因为我直接从developer.androID.com获取了代码

谢谢

解决方法:

对不起,找到了答案.当我在fragment1.java中膨胀视图时,它被附加到root.将最后一个标志改为false,现在好了.
