三个标签页置于顶端

效果图：

在文件BoardTabHost.java中定义页面切换的效果；切换页面时，当前页面滑出，目标页面滑入。这是2个不同的动画设定动画时要区分对待

import android.content.Context;import android.util.AttributeSet;import android.view.animation.Animation;import android.view.animation.TranslateAnimation;import android.widget.TabHost;public class BoardTabHost extends TabHost {private int currentTab = 0;int duration = 1000;// ms; the bigger the slowerpublic BoardTabHost(Context context) {super(context);}public BoardTabHost(Context context, AttributeSet attr) {super(context, attr);}@Overridepublic void setCurrentTab(int index) {// we need two animation here: first one is fading animation, 2nd one is coming animation// translateAnimation of fading fragmentif (index > currentTab) {// fly right to left and leave the screenTranslateAnimation translateAnimation = new TranslateAnimation(Animation.RELATIVE_TO_SELF, 0f,Animation.RELATIVE_TO_SELF, -1.0f,Animation.RELATIVE_TO_SELF, 0f,Animation.RELATIVE_TO_SELF, 0f);translateAnimation.setDuration(duration);getCurrentView().startAnimation(translateAnimation);} else if (index < currentTab) {// fly left to rightTranslateAnimation translateAnimation = new TranslateAnimation(Animation.RELATIVE_TO_SELF, 0f,Animation.RELATIVE_TO_SELF, 1.0f,Animation.RELATIVE_TO_SELF, 0f,Animation.RELATIVE_TO_SELF, 0f);translateAnimation.setDuration(duration);getCurrentView().startAnimation(translateAnimation);}super.setCurrentTab(index);// the current tab is index now// translateAnimation of adding fragmentif (index > currentTab) {TranslateAnimation translateAnimation = new TranslateAnimation(Animation.RELATIVE_TO_PARENT, 1.0f,Animation.RELATIVE_TO_PARENT, 0f, Animation.RELATIVE_TO_PARENT, 0f,Animation.RELATIVE_TO_PARENT, 0f);translateAnimation.setDuration(duration);getCurrentView().startAnimation(translateAnimation);} else if (index < currentTab) {TranslateAnimation translateAnimation = new TranslateAnimation(Animation.RELATIVE_TO_PARENT, -1.0f,Animation.RELATIVE_TO_PARENT, 0f,Animation.RELATIVE_TO_PARENT, 0f,Animation.RELATIVE_TO_PARENT, 0f);translateAnimation.setDuration(duration);getCurrentView().startAnimation(translateAnimation);}currentTab = index;}}

对应的布局文件activity_board.xml

使用BoardTabHost，装载一个竖直的LinearLayout；上面是TabWidget，装载标签；后面是fragment的FrameLayout
可以看到这里有3个fragment，待会在activity中也设置3个标签

<?xml version="1.0" encoding="utf-8"?><com.rust.tabhostdemo.BoardTabHostandroid:id="@android:id/tabhost"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"tools:context="com.rust.tabhostdemo.BoardActivity"><LinearLayoutandroid:layout_width="match_parent"android:layout_height="match_parent"android:orientation="vertical"><TabWidgetandroid:id="@android:id/tabs"android:layout_width="match_parent"android:layout_height="wrap_content"/><FrameLayoutandroid:id="@android:id/tabcontent"android:layout_width="match_parent"android:layout_height="match_parent"><fragmentandroid:id="@+id/fragment_tab1"android:name="com.rust.tabhostdemo.TabFragment1"android:layout_width="match_parent"android:layout_height="match_parent"/><fragmentandroid:id="@+id/fragment_tab2"android:name="com.rust.tabhostdemo.TabFragment2"android:layout_width="match_parent"android:layout_height="match_parent"/><fragmentandroid:id="@+id/fragment_tab3"android:name="com.rust.tabhostdemo.TabFragment3"android:layout_width="match_parent"android:layout_height="match_parent"/></FrameLayout></LinearLayout></com.rust.tabhostdemo.BoardTabHost>

值得一提的是，这里的id要用android指定的id；
比如@android:id/tabhost，@android:id/tabcontent，@android:id/tabs；否则系统找不到对应控件而报错

BoardActivity.java中设置了3个标签页，并指定了标签对应的fragment

import android.support.v4.app.FragmentActivity;import android.os.Bundle;public class BoardActivity extends FragmentActivity {public static final String TAB1 = "tab1";public static final String TAB2 = "tab2";public static final String TAB3 = "tab3";public static BoardTabHost boardTabHost;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_board);boardTabHost = (BoardTabHost) findViewById(android.R.id.tabhost);boardTabHost.setup();boardTabHost.addTab(boardTabHost.newTabSpec(TAB1).setIndicator(getString(R.string.tab1_name)).setContent(R.id.fragment_tab1));boardTabHost.addTab(boardTabHost.newTabSpec(TAB2).setIndicator(getString(R.string.tab2_name)).setContent(R.id.fragment_tab2));boardTabHost.addTab(boardTabHost.newTabSpec(TAB3).setIndicator(getString(R.string.tab3_name)).setContent(R.id.fragment_tab3));boardTabHost.setCurrentTab(0);}}

主要文件目录：

── layout

├── activity_board.xml
├── fragment_tab1.xml
├── fragment_tab2.xml
└── fragment_tab3.xml

── tabhostdemo

├── BoardActivity.java
├── BoardTabHost.java
├── TabFragment1.java
├── TabFragment2.java
└── TabFragment3.java

以上所述是小编给大家介绍的Android中使用TabHost 与 Fragment 制作页面切换效果的相关内容，希望对大家有所帮助！
