Android TabHost用法.doc

关于Android TabHost切换Tab字体的颜色背景颜色改变 先是layout文件夹中的布局文件，代码如下： TabHost xmlns:android=/apk/res/android android:id=@android:id/tabhost android:layout_width=fill_parent android:layout_height=fill_parent LinearLayout android:layout_width=fill_parent android:layout_height=fill_parent android:orientation=vertical android:background=@drawable/category_bg android:padding=0dp TabWidget android:id=@android:id/tabs android:layout_width=wrap_content android:layout_height=40dp/ FrameLayout android:id=@android:id/tabcontent android:layout_width=fill_parent android:layout_height=fill_parent android:background=@drawable/context_bg android:padding=0dp / /LinearLayout /TabHost 然后是java文件， [java] package com.dzdc.activity; import android.app.TabActivity; import android.content.Intent; import android.graphics.Typeface; import android.os.Bundle; import android.view.KeyEvent; import android.view.View; import android.view.Window; import android.view.WindowManager; import android.widget.TabHost; import android.widget.TabHost.OnTabChangeListener; import android.widget.TextView; import com.dzdc.R; @SuppressWarnings(deprecation) public class IndexActivity extends TabActivity { private String[] tabMenu = { 热菜, 冷菜, 海鲜, 川菜, 酒饮, 招牌菜 }; private Intent intent0, intent1, intent2, intent3, intent4, intent5; private Intent[] intents = { intent0, intent1, intent2, intent3, intent4, intent5 }; private TabHost.TabSpec tabSpec0, tabSpec1, tabSpec2, tabSpec3, tabSpec4, tabSpec5; private TabHost.TabSpec[] tabSpecs = { tabSpec0, tabSpec1, tabSpec2, tabSpec3, tabSpec4, tabSpec5 }; private TabHost tabHost = null; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState);
