先上模仿的对象:QQ的电话/消息 界面
技术分享
用户点击消息或者电话会切换不同的界面

然后再上自己实现的界面
技术分享
然后再附带了一些每一个Fragment内部的操作,来模拟切换后的效果

实现方法: 一个自定义控件+下面的Fragment.利用setOnSegmentControlViewClickListener方法来监听用户的点击来对界面进行操作。

项目目录结构
技术分享
一个主Activity加一系列分页的Fragment(其实这里可以用Java代码来添加Fragment,但是考虑到大家的使用性,还是用麻烦的方法。毕竟 Copy走就直接可以改每一个单独的Fragment进行修改了)

主Activity

package com.wjj.wjjdemo;
import com.wjj.wjjdemo.customView.SegmentControlView;
import com.wjj.wjjdemo.customView.SegmentControlView.onSegmentControlViewClickListener;
import com.wjj.wjjdemo.fragment.fragmenta;
import com.wjj.wjjdemo.fragment.fragmentb;
import com.wjj.wjjdemo.fragment.fragmentc;

import android.app.Activity;
import android.app.Fragment;
import android.app.FragmentManager;
import android.app.FragmentTransaction;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;


public class MainActivity extends Activity {
    private SegmentControlView SegmentControlView = null;
    /*等会要用于切换的3个Fragment*/
    private fragmenta fragmenta;
    private fragmentb fragmentb;
    private fragmentc fragmentc;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        FindById();
     // 设置默认的Fragment  
        setDefaultFragment();
        Listener();
    }

    private void FindById(){
        SegmentControlView = (SegmentControlView) findViewById(R.id.SegmentControlView);
    }

    private void Listener(){
        SegmentControlView.setOnSegmentControlViewClickListener(new onSegmentControlViewClickListener() {

            @Override
            public void onSegmentControlViewClick(View view, int position) {
                FragmentManager fm = getFragmentManager();  
                // 开启Fragment事务  
                FragmentTransaction transaction = fm.beginTransaction(); 

                switch (position) {
                    case 0:
                        if (fragmenta == null)  
                        {  
                            fragmenta = new fragmenta();  
                        }  
                        // 使用当前Fragment的布局替代id_content的控件  
                        transaction.replace(R.id.fragmentlayout, fragmenta);  
                        // 事务提交  
                        transaction.commit(); 
                        break;
                    case 1:
                     if (fragmentb == null)  
                        {  
                            fragmentb = new fragmentb();  
                        }  
                        // 使用当前Fragment的布局替代id_content的控件  
                        transaction.replace(R.id.fragmentlayout, fragmentb);  
                        // 事务提交  
                        transaction.commit();       
                        break;
                    case 2:
                     if (fragmentc == null)  
                        {  
                            fragmentc = new fragmentc();  
                        }  
                        // 使用当前Fragment的布局替代id_content的控件  
                        transaction.replace(R.id.fragmentlayout, fragmentc);  
                        // 事务提交  
                        transaction.commit(); 
                        break;
                    default:
                        break;
                }
            }
        });
    }

    private void setDefaultFragment(){
        FragmentManager fm = getFragmentManager();  
        FragmentTransaction transaction = fm.beginTransaction(); 
        fragmenta=new fragmenta();
        transaction.replace(R.id.fragmentlayout, fragmenta);  
        transaction.commit();  
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();
        if (id == R.id.action_settings) {
            return true;
        }
        return super.onOptionsItemSelected(item);
    }
}

其实 当中监听时间的transaction.commit(); 些多余了,大家就自行修改吧,放到函数外面就行了,因为会break出去,并不需要每一个case里都要加

自定义View

    private TextView textView1 = null;

                if (textView1.isSelected()) {

                }
                textView1.setSelected(true);
                textView2.setSelected(false);

                if (listener != null) {
                    listener.onSegmentControlViewClick(textView1, 0);
                }
            }
        });
        textView2.setOnClickListener(new OnClickListener() {

            @Override

                if (textView2.isSelected()) {

                if (listener != null) {
                    listener.onSegmentControlViewClick(textView2, 1);
                }
            }
        });

        textView3.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                if (textView3.isSelected()) {
                    return;
                }

                textView1.setSelected(false);
                textView2.setSelected(false);
                if (listener != null) {
                    listener.onSegmentControlViewClick(textView2, 2);
                }
            }
        });
    }

    /**
     * 设置字体大小 单位dip
     * @param dp

    public void setOnSegmentControlViewClickListener(onSegmentControlViewClickListener listener) {
        this.listener = listener;
    }

    public static interface onSegmentControlViewClickListener{

        /**
         * @param v
         * @param position 0-左边 1-中间 2-右边

    private static int dp2Px(Context context, float dp) {
        final float scale = context.getResources().getDisplayMetrics().density;
        return (int) (dp * scale + 0.5f);
    }
}

整体封装的还不错,需要修改UI的观众老爷可自行进行修改,大体功能已经实现了

3个Fragment中的一个

public class fragmenta extends Fragment{
    Button fragmentaButton;
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        View view= inflater.inflate(R.layout.fragemnta, container, false);
        fragmentaButton=(Button)view.findViewById(R.id.fragmentaButtona);
        fragmentaButton.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                Toast.makeText(getActivity(), "fragmenta", 1).show();
            }
        });
        return view;
    }

}

主布局文件

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="com.wjj.wjjdemo.MainActivity"
    android:background="@color/white">

    <com.wjj.wjjdemo.customView.SegmentControlView
        android:id="@+id/SegmentControlView"
        android:layout_width="240dp"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"
        android:background="@drawable/seg_linear"
        android:padding="0.5dp" >
    </com.wjj.wjjdemo.customView.SegmentControlView>

    <FrameLayout
        android:id="@+id/fragmentlayout"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_alignParentBottom="true"
        android:layout_below="@+id/SegmentControlView" >
    </FrameLayout>

</RelativeLayout>

这里要补充下,楼主在FrameLayout节点这一部分犯了一个错误,之前用Fragment来填充这一部分,导致出现了2个View重叠的问题,所以用FrameLayout之类的布局来填充就好了。

大体主要的代码就这些了,源码在下面会补上,布局文件资源文件什么的都在里面了,大家拿来就可以用。
