Fragment 布局

做了两个界面跳转的Fragment 只实现了简单跳转代码不多可以借鉴

有个布局文件两个java文件

代码如下

public class Frame_main extends AppCompatActivity{    public Frame_data mFrame_data;    public Frame_chat mFrame_chat;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        initView();    }    public void initView(){        ImageView frame_data;        ImageView frame_chat;        frame_data = (ImageView) findViewById(R.id.frame_data);        frame_chat = (ImageView) findViewById(R.id.frame_chat);        frame_data.setOnClickListener ( new View.OnClickListener ( )        {            @Override            public void onClick(View v)            {                FragmentManager fm = getFragmentManager();                //开启Fragment事务                FragmentTransaction fragmentTransaction = fm.beginTransaction();                if (mFrame_data == null){                    mFrame_data = new Frame_data ();                }                //使用当前的Fragment的布局代替id_bottombar_liaotian的控件                fragmentTransaction.replace(R.id.frame_main,mFrame_data);                //事务提交                fragmentTransaction.commit();            }        } );        frame_chat.setOnClickListener ( new View.OnClickListener ( )        {            @Override            public void onClick(View v)            {                FragmentManager fm = getFragmentManager();                //开启Fragment事务                FragmentTransaction fragmentTransaction = fm.beginTransaction();                if (mFrame_chat == null){                    mFrame_chat = new Frame_chat ();                }                fragmentTransaction.replace(R.id.frame_main,mFrame_chat);                //事务提交                fragmentTransaction.commit();            }        } );        //设置默认的Fragment        setDefaultFragment();    }    private void setDefaultFragment(){        FragmentManager fragmentManager = getFragmentManager();        FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();        mFrame_data=new Frame_data ();        fragmentTransaction.replace(R.id.frame_main,mFrame_data);        fragmentTransaction.commit();    }}

2、第一个界面的java

public class Frame_data extends Fragment{    @Override    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){        return inflater.inflate(R.layout.frame_data,container,false);    }}

3、第二个界面的java

public class Frame_chat extends Fragment{    @Override    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){        return inflater.inflate(R.layout.frame_chat,container,false);    }}

布局文件如下

1、frame_main.xml

<RelativeLayout    android:id="@+id/content_main"    xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:app="http://schemas.android.com/apk/res-auto"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    app:layout_behavior="@string/appbar_scrolling_view_behavior"    tools:context="com.mars.aaaa.MainActivity"    tools:showIn="@layout/app_bar_main">    <FrameLayout        android:id="@+id/frame_main"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:layout_alignParentTop="true"        android:layout_alignParentStart="true"/>    <include        android:id="@+id/include_title"        android:layout_width="match_parent"        android:layout_height="45dp"        layout="@layout/frame_title"        android:layout_marginBottom="10dp"        android:layout_alignParentBottom="true"        android:layout_alignParentStart="true"/></RelativeLayout>

2、frame_title.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"              xmlns:tools="http://schemas.android.com/tools"              tools:showIn="@layout/content_main">    <LinearLayout        android:background="#f2f0f0"        android:layout_width="match_parent"        android:layout_height="wrap_content">        <Space            android:layout_width="70dp"            android:layout_height="wrap_content"/>        <ImageView            android:id="@+id/frame_data"            android:background="@drawable/touxiang_nv"            android:layout_width="55dp"            android:layout_height="55dp"/>        <Space            android:layout_width="130dp"            android:layout_height="wrap_content"/>        <ImageView            android:id="@+id/frame_chat"            android:background="@drawable/touxiang"            android:layout_width="55dp"            android:layout_height="55dp"/>    </LinearLayout></LinearLayout>

3、剩下两个文件基本差不多就列举一个

<?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"><TextView    android:layout_width="match_parent"    android:layout_height="wrap_content"    android:text="data"/></LinearLayout>
