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 slower public BoardTabHost(Context context) { super(context); } public BoardTabHost(Context context, AttributeSet attr) { super(context, attr); } @Override public void setCurrentTab(int index) { // we need two animation here: first one is fading animation, 2nd one is coming animation // translateAnimation of fading fragment if (index > currentTab) {// fly right to left and leave the screen TranslateAnimation translateAnimation = new TranslateAnimation( Animation.RELATIVE_TO_SELF/* fromXType */, 0f/* fromXValue */, Animation.RELATIVE_TO_SELF/* toXType */, -1.0f/* toXValue */, Animation.RELATIVE_TO_SELF, 0f, Animation.RELATIVE_TO_SELF, 0f ); translateAnimation.setDuration(duration); getCurrentView().startAnimation(translateAnimation); } else if (index < currentTab) {// fly left to right TranslateAnimation 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 fragment if (index > currentTab) { TranslateAnimation translateAnimation = new TranslateAnimation( Animation.RELATIVE_TO_PARENT, 1.0f,/* fly into screen */ Animation.RELATIVE_TO_PARENT, 0f, /* screen location */ 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.BoardTabHost android: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"> <LinearLayout android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"> <TabWidget android:id="@android:id/tabs" android:layout_width="match_parent" android:layout_height="wrap_content"/> <FrameLayout android:id="@android:id/tabcontent" android:layout_width="match_parent" android:layout_height="match_parent"> <fragment android:id="@+id/fragment_tab1" android:name="com.rust.tabhostdemo.TabFragment1" android:layout_width="match_parent" android:layout_height="match_parent"/> <fragment android:id="@+id/fragment_tab2" android:name="com.rust.tabhostdemo.TabFragment2" android:layout_width="match_parent" android:layout_height="match_parent"/> <fragment android: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; @Override protected 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：

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！
