Android 高仿QQ 界面滑动效果
点击或者滑动切换画面，用ViewPager实现，
首先是布局文件：
<LinearLayout xmlns:Android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="62dip"
android:orientation="vertical"
android:background="@drawable/top_theme_blue">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="36dip"
android:orientation="horizontal"
android:gravity="center_vertical">
<ImageView
android:id="@+id/main_avatar"
android:layout_width="32dip"
android:layout_height="32dip"
android:src="@drawable/avatar" />
<TextView
android:id="@+id/main_nick"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#FFFFFF"
android:text="Vestigge"/>
<ImageView
android:layout_width="14dip"
android:layout_height="14dip"
android:src="@drawable/status_online"/>
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="26dip"
android:orientation="horizontal"
android:gravity="bottom">
<RadioGroup
android:id="@+id/main_radiogroup"
android:orientation="horizontal"
android:paddingTop="1dp"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<RadioButton
android:id="@+id/main_radio_recent"
android:checked="true"
android:text="动态"
android:textColor="@color/tab_text"
android:drawableBottom="@drawable/top_tab_selector"
style="@style/radio_style"/>
<RadioButton
android:id="@+id/main_radio_buddy"
android:text="群组"
android:textColor="@color/tab_text"
android:drawableBottom="@drawable/top_tab_selector"
style="@style/radio_style"/>
<RadioButton
android:id="@+id/main_radio_group"
android:text="好友"
android:textColor="@color/tab_text"
android:drawableBottom="@drawable/top_tab_selector"
style="@style/radio_style"
android:checked="true"/>
<RadioButton
android:id="@+id/main_radio_trends"
android:text="会话"
android:textColor="@color/tab_text"
android:drawableBottom="@drawable/top_tab_selector"
style="@style/radio_style"/>
</RadioGroup>
</LinearLayout>
</LinearLayout>
<android.support.v4.view.ViewPager
android:id="@+id/main_viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent" >
</android.support.v4.view.ViewPager>
</LinearLayout>
代码：

viewPager.setAdapter(new PagerAdapter(){
public int getCount() {

}
public boolean isViewFromObject(View view, Object objcet) {

}
//这里会对需要进行水平切换的页面进行了加载和初始化 android:tileMode="repeat"
public Object instantiateItem(View view, int id) {
((ViewPager)view).addView(pageViews.get(id));
return pageViews.get(id);
}
public void destroyItem(View view, int id, Object arg2) {

}
});
viewPager.setCurrentItem(2);//默认显示的是好友页面
radioGroup = (RadioGroup) findViewById(R.id.main_radiogroup);
radioGroup.setOnCheckedChangeListener(new OnCheckedChangeListener() {
public void onCheckedChanged(RadioGroup group, int checkedId) {
setClick(checkedId);
}
});
}

pageViews.add(2,view3);
pageViews.add(3,view4);
}
public void setClick(int id) {
