先上模仿的对象：QQ的电话/消息 界面
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
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
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
@SuppressLint("NewApi")
public class SegmentControlView extends LinearLayout {
private TextView textView1 = null;
private TextView textView2 = null;
private TextView textView3 = null;
private View verTextView1 = null;//中间的竖线
private View verTextView2 = null;//中间的竖线
private onSegmentControlViewClickListener listener;
public SegmentControlView(Context context) {

setSegmentText(2, getContext().getString(R.string.all_list));
setSegmentTextSize(16);//设置文字大小
XmlPullParser xrp = getResources().getXml(R.drawable.seg_text_color_selector);
try {
ColorStateList csl = ColorStateList.createFromXml(getResources(), xrp);
textView1.setTextColor(csl);
textView2.setTextColor(csl);
textView3.setTextColor(csl);
} catch (Exception e) {
}
textView1.setGravity(Gravity.CENTER);
textView2.setGravity(Gravity.CENTER);

textView1.setOnClickListener(new OnClickListener() {

public void onClick(View v) {

return;
}
textView1.setSelected(true);
textView2.setSelected(false);
textView3.setSelected(false);
if (listener != null) {
listener.onSegmentControlViewClick(textView1, 0);
}
}
});
textView2.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
if (textView2.isSelected()) {
return;
}
textView2.setSelected(true);
textView1.setSelected(false);
textView3.setSelected(false);
if (listener != null) {
listener.onSegmentControlViewClick(textView2, 1);
}
}
});
textView3.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
if (textView3.isSelected()) {
return;
}
textView3.setSelected(true);
textView1.setSelected(false);
textView2.setSelected(false);
if (listener != null) {
listener.onSegmentControlViewClick(textView2, 2);
}
}
});
}
/**

public void setSegmentTextSize(int dp) {
textView1.setTextSize(TypedValue.COMPLEX_UNIT_DIP, dp);
textView2.setTextSize(TypedValue.COMPLEX_UNIT_DIP, dp);

}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。
