首先实现底部和底部布局
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="45dp" android:background="@drawable/title_bar" android:gravity="center" android:orientation="vertical" > <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center" android:text="微信" android:textColor="#ffffff" android:textSize="20sp" android:textStyle="bold" /> </LinearLayout>
底部布局
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="55dp" android:background="@drawable/bottom_bar" android:orientation="horizontal" > <LinearLayout android:id="@+id/id_tab_weixin" android:layout_width="0dp" android:layout_height="fill_parent" android:layout_weight="1" android:gravity="center" android:orientation="vertical" > <ImageButton android:id="@+id/id_tab_weixin_img" android:layout_width="wrap_content" android:layout_height="wrap_content" android:background="#00000000" android:clickable="false" android:src="@drawable/tab_weixin_pressed" /> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="微信" android:textColor="#ffffff" /> </LinearLayout> <LinearLayout android:id="@+id/id_tab_frd" android:layout_width="0dp" android:layout_height="fill_parent" android:layout_weight="1" android:gravity="center" android:orientation="vertical" > <ImageButton android:id="@+id/id_tab_frd_img" android:layout_width="wrap_content" android:layout_height="wrap_content" android:background="#00000000" android:clickable="false" android:src="@drawable/tab_find_frd_normal" /> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="朋友" android:textColor="#ffffff" /> </LinearLayout> <LinearLayout android:id="@+id/id_tab_address" android:layout_width="0dp" android:layout_height="fill_parent" android:layout_weight="1" android:gravity="center" android:orientation="vertical" > <ImageButton android:id="@+id/id_tab_address_img" android:layout_width="wrap_content" android:layout_height="wrap_content" android:background="#00000000" android:clickable="false" android:src="@drawable/tab_address_normal" /> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="通讯录" android:textColor="#ffffff" /> </LinearLayout> <LinearLayout android:id="@+id/id_tab_settings" android:layout_width="0dp" android:layout_height="fill_parent" android:layout_weight="1" android:gravity="center" android:orientation="vertical" > <ImageButton android:id="@+id/id_tab_settings_img" android:layout_width="wrap_content" android:layout_height="wrap_content" android:background="#00000000" android:clickable="false" android:src="@drawable/tab_settings_normal" /> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="设置" android:textColor="#ffffff" /> </LinearLayout> </LinearLayout>
注意这里将LinearLayout中的子View ImageButton 的clickable设置为false,这样才能使得整个LiearLayout 响应点击事件
activity_main.xml
<LinearLayout 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:orientation="vertical" > <include layout="@layout/top" /> <android.support.v4.view.ViewPager android:id="@+id/id_viewpager" android:layout_width="fill_parent" android:layout_height="0dp" android:layout_weight="1" > </android.support.v4.view.ViewPager> <include layout="@layout/bottom" /> </LinearLayout>
每一个tab页面，这里只列举一个，其他的都相似
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <TextView android:layout_width="fill_parent" android:layout_height="fill_parent" android:gravity="center" android:text="This is Weixin Tab" android:textSize="30sp" android:textStyle="bold" /> </LinearLayout>
MainActivity类
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<View> mViews = new ArrayList<View>();
//用来保存view的数组 // 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) { View view = mViews.get(position); container.addView(view); return view; } @Override public boolean isViewFromObject(View arg0, Object arg1) { return arg0 == arg1; } @Override public int getCount() { return mViews.size(); } }; mViewPager.setAdapter(mAdapter); } @Override public void onClick(View v) { resetImg(); switch (v.getId()) { case R.id.id_tab_weixin: mViewPager.setCurrentItem(0); mWeixinImg.setImageResource(R.drawable.tab_weixin_pressed); break; case R.id.id_tab_frd: mViewPager.setCurrentItem(1); mFrdImg.setImageResource(R.drawable.tab_find_frd_pressed); break; case R.id.id_tab_address: mViewPager.setCurrentItem(2); mAddressImg.setImageResource(R.drawable.tab_address_pressed); break; case R.id.id_tab_settings: mViewPager.setCurrentItem(3); mSettingImg.setImageResource(R.drawable.tab_settings_pressed); break; default: break; } } private void resetImg() { mWeixinImg.setImageResource(R.drawable.tab_weixin_normal); mFrdImg.setImageResource(R.drawable.tab_find_frd_normal); mAddressImg.setImageResource(R.drawable.tab_address_normal); mSettingImg.setImageResource(R.drawable.tab_settings_normal); } }
这样就实现了即可以滑动也可以点击tab实现页面的转换
