Android项目Tab类型主界面大总结 Fragment+TabPageIndicator+ViewPager

转载请标明出处：http://blog.csdn.net/lmj623565791/article/details/24740977

Android现在实现Tab类型的界面方式越来越多，今天就把常见的实现方式给大家来个总结。目前写了：

1、传统的ViewPager实现

2、FragmentManager+Fragment实现

3、ViewPager+FragmentPagerAdapter实现

4、TabPageIndicator+ViewPager+FragmentPagerAdapter

1、传统的ViewPager实现

主要就是ViewPager+ViewAdapter这个还是比较常见的，就不多说了

效果图：

@Override

{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mInflater = LayoutInflater.from(this);
mViewPager = (ViewPager) findViewById(R.id.id_viewpager);

/**

initView();

mViewPager.setAdapter(mAdapter);

mViewPager.setOnPageChangeListener(new OnPageChangeListener()
{

@Override
public void onPageSelected(int position)
{
resetTabBtn();
switch (position)
{
case 0:

@Override

评价：所有的代码都集中在一个Activity中，显得代码比较乱。

2、FragmentManager+Fragment实现

主要利用了Fragment在主内容界面对Fragment的add,hide等事务操作。

评价：每个Fragment中的控件的处理，都是独立到各自的类中，相对来说主Activity简化了不少，可惜没有左右滑动的效果了。

3、ViewPager+Fragment实现

主要通过ViewPager和FragmentPagerAdapter一起来实现。

case 3:
((ImageButton) mTabBtnSettings.findViewById(R.id.btn_tab_bottom_setting))

break;
}

currentIndex = position;
}

@Override
public void onPageScrolled(int arg0, float arg1, int arg2)
{

}

@Override
public void onPageScrollStateChanged(int arg0)
{
}
});

}

protected void resetTabBtn()
{
((ImageButton) mTabBtnWeixin.findViewById(R.id.btn_tab_bottom_weixin))
.setImageResource(R.drawable.tab_weixin_normal);
((ImageButton) mTabBtnFrd.findViewById(R.id.btn_tab_bottom_friend))
.setImageResource(R.drawable.tab_find_frd_normal);

}

private void initView()
{

mTabBtnWeixin = (LinearLayout) findViewById(R.id.id_tab_bottom_weixin);
mTabBtnFrd = (LinearLayout) findViewById(R.id.id_tab_bottom_friend);
mTabBtnAddress = (LinearLayout) findViewById(R.id.id_tab_bottom_contact);
mTabBtnSettings = (LinearLayout) findViewById(R.id.id_tab_bottom_setting);

MainTab01 tab01 = new MainTab01();
MainTab02 tab02 = new MainTab02();
MainTab03 tab03 = new MainTab03();
MainTab04 tab04 = new MainTab04();
mFragments.add(tab01);
mFragments.add(tab02);
mFragments.add(tab03);
mFragments.add(tab04);
}
}

还有4个TabFragment，下面贴一个，四个基本一样

[java]
view plaincopyprint?





package com.example.mainframework03; import android.os.Bundle; import android.support.v4.app.Fragment; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; public class MainTab01 extends Fragment { @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { return inflater.inflate(R.layout.main_tab_01, container, false); } }

package com.example.mainframework03;

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

public class MainTab01 extends Fragment
{

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
return  inflater.inflate(R.layout.main_tab_01, container, false);

}

}

评价：实现效果和第一种效果一模一样，每个Fragment独自处理自己内部的逻辑，代码整洁很多，并且支持左右滑动。感觉是第一种和第二种的结合版本。

4、TabPageIndicator+ViewPager+FragmentPagerAdapter

实现方式和3是一致的，但是使用了TabPageIndicator作为tab的指示器，效果还是不错的，这个之前写过，就不再贴代码了。

好了，就总结了这么多，肯定还有很多别的实现方式，大家可以留言，有时间会继续完善这篇总结的。
