Android几种Tab的实现方法
学了这久Android，今天来总结一下几种Tab的实现方法
实现方法一：
ViewPage来实现
首先创建一个top.xml布局和一个bottom.xml布局，然后在主界面中通过Include属性添加
top.xml
bottom.xml
main.xml,通过include引入，中间使用ViewPager
然后写几个界面的布局：用于切换的时候显示。这里我就写一个，其他类似
tob01.xml
MainActivity.java
package com.imooc.tab01;
import java.util.ArrayList;
import java.util.List;
import android.app.Activity;
import android.os.Bundle;
import android.support.v4.view.PagerAdapter;
import android.support.v4.view.ViewPager;
import android.support.v4.view.ViewPager.OnPageChangeListener;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup;
import android.view.Window;
import android.widget.ImageButton;
import android.widget.LinearLayout;
public class MainActivity extends Activity implements OnClickListener
{
private ViewPager mViewPager;
private PagerAdapter mAdapter;
private List mViews = new ArrayList();
// TAB
private LinearLayout mTabWeixin;
private LinearLayout mTabFrd;
private LinearLayout mTabAddress;
private LinearLayout mTabSetting;
private ImageButton mWeixinImg;
private ImageButton mFrdImg;
private ImageButton mAddressImg;
private ImageButton mSettingImg;
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.activity_main);
initView();
initEvents();
}
private void initEvents()
{
mTabWeixin.setOnClickListener(this);
mTabFrd.setOnClickListener(this);
mTabAddress.setOnClickListener(this);
mTabSetting.setOnClickListener(this);
mViewPager.setOnPageChangeListener(new OnPageChangeListener()
{
@Override
public void onPageSelected(int arg0)
{
int currentItem = mViewPager.getCurrentItem();
resetImg();
switch (currentItem)
{
case 0:
mWeixinImg.setImageResource(R.drawable.tab_weixin_pressed);
break;
case 1:
mFrdImg.setImageResource(R.drawable.tab_find_frd_pressed);
break;
case 2:
mAddressImg.setImageResource(R.drawable.tab_address_pressed);
break;
case 3:
mSettingImg.setImageResource(R.drawable.tab_settings_pressed);
break;
}
}
@Override
public void onPageScrolled(int arg0, float arg1, int arg2)
{
}
@Override
public void onPageScrollStateChanged(int arg0)
{
}
});
}
private void initView()
{
mViewPager = (ViewPager) findViewById(R.id.id_viewpager);
// tabs
mTabWeixin = (LinearLayout) findViewById(R.id.id_tab_weixin);
mTabFrd = (LinearLayout) findViewById(R.id.id_tab_frd);
mTabAddress = (LinearLayout) findViewById(R.id.id_tab_address);
mTabSetting = (LinearLayout) findViewById(R.id.id_tab_settings);
// ImageButton
mWeixinImg = (ImageButton) findViewById(R.id.id_tab_weixin_img);
mFrdImg = (ImageButton) findViewById(R.id.id_tab_frd_img);
mAddressImg = (ImageButton) findViewById(R.id.id_tab_address_img);
mSettingImg = (ImageButton) findViewById(R.id.id_tab_settings_img);
LayoutInflater mInflater = LayoutInflater.from(this);
View tab01 = mInflater.inflate(R.layout.tab01, null);
View tab02 = mInflater.inflate(R.layout.tab02, null);
View tab03 = mInflater.inflate(R.layout.tab03, null);
View tab04 = mInflater.inflate(R.layout.tab04, null);
mViews.add(tab01);
mViews.add(tab02);
mViews.add(tab03);
mViews.add(tab04);
mAdapter = new PagerAdapter()
{
@Override
public void destroyItem(ViewGroup container, int position,
Object object)
{
container.removeView(mViews.get(position));
}
@Override
public Object instantiateItem(ViewGroup container, int position)
{
