先看效果图:
1.main.xml文件代码:
<?xml version="1.0" encoding="utf-8"?> <TabHost xmlns:android="http://schemas.android.com/apk/res/android" android:id="@android:id/tabhost" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="@drawable/mnv" > <LinearLayout android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <FrameLayout android:id="@android:id/tabcontent" android:layout_width="fill_parent" android:layout_height="0.0dip" android:layout_weight="1.0"/> <TabWidget android:id="@android:id/tabs" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_weight="0.0" android:visibility="gone"/> <RadioGroup android:id="@+id/main_tab" android:background="@drawable/maintab_toolbar_bg" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="wrap_content" android:gravity="center_vertical" android:layout_gravity="bottom"> <RadioButton android:layout_marginTop="0.5dip" android:text="@string/main_home" android:drawableTop="@drawable/icon_0_n" android:id="@+id/radio_button0" style="@style/main_tab_bottom"/> <RadioButton android:layout_marginTop="0.5dip" android:text="@string/main_news" android:drawableTop="@drawable/icon_1" android:id="@+id/radio_button1" style="@style/main_tab_bottom"/> <RadioButton android:layout_marginTop="0.5dip" android:text="@string/main_shou_cang" android:drawableTop="@drawable/icon_3_n" android:id="@+id/radio_button2" style="@style/main_tab_bottom"/> <RadioButton android:layout_marginTop="1.0dip" android:text="@string/main_my_info" android:drawableTop="@drawable/icon_4_n" android:id="@+id/radio_button3" style="@style/main_tab_bottom"/> <RadioButton android:layout_marginTop="0.5dip" android:text="@string/more" android:drawableTop="@drawable/icon_5_n" android:id="@+id/radio_button4" style="@style/main_tab_bottom"/> </RadioGroup> </LinearLayout> </TabHost>
2.MainTabActivity.java代码:
package com.jun.activity; import android.app.TabActivity; import android.content.Intent; import android.os.Bundle; import android.view.Window; import android.widget.RadioGroup; import android.widget.TabHost; import android.widget.RadioGroup.OnCheckedChangeListener; import android.widget.Toast; public class MainTabActivity extends TabActivity implements OnCheckedChangeListener{ private RadioGroup mainTab; private TabHost tabhost; private Intent iHome; private Intent iNews; private Intent iInfo; private Intent iSearch; private Intent iMore; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_NO_TITLE); setContentView(R.layout.main); mainTab=(RadioGroup)findViewById(R.id.main_tab); mainTab.setOnCheckedChangeListener(this); tabhost = getTabHost(); // 在此进行Intent的初始化,设置Intent将传进那个Activity // iHome = new Intent(this, HomeActivity.class); // tabhost.addTab(tabhost.newTabSpec("iHome") // .setIndicator(getResources().getString(R.string.main_home), getResources().getDrawable(R.drawable.icon_1_n)) // .setContent(iHome)); // // iNews = new Intent(this, NewsActivity.class); // tabhost.addTab(tabhost.newTabSpec("iNews") // .setIndicator(getResources().getString(R.string.main_news), getResources().getDrawable(R.drawable.icon_2_n)) // .setContent(iNews)); // // iInfo = new Intent(this, MyInfoActivity.class); // tabhost.addTab(tabhost.newTabSpec("iInfo") // .setIndicator(getResources().getString(R.string.main_my_info), getResources().getDrawable(R.drawable.icon_3_n)) // .setContent(iInfo)); // // iSearch = new Intent(this,SearchActivity.class); // tabhost.addTab(tabhost.newTabSpec("iSearch") // .setIndicator(getResources().getString(R.string.menu_search), getResources().getDrawable(R.drawable.icon_4_n)) // .setContent(iSearch)); // // iMore = new Intent(this, MoreActivity.class); // tabhost.addTab(tabhost.newTabSpec("iMore") // .setIndicator(getResources().getString(R.string.more), getResources().getDrawable(R.drawable.icon_5_n)) // .setContent(iMore)); } @Override public void onCheckedChanged(RadioGroup group, int checkedId) { switch(checkedId){ case R.id.radio_button0: Toast.makeText(MainTabActivity.this,"button0",Toast.LENGTH_SHORT).show(); break; case R.id.radio_button1: Toast.makeText(MainTabActivity.this,"button1",Toast.LENGTH_SHORT).show(); break; case R.id.radio_button2: Toast.makeText(MainTabActivity.this,"button2",Toast.LENGTH_SHORT).show(); break; case R.id.radio_button3: Toast.makeText(MainTabActivity.this,"button3",Toast.LENGTH_SHORT).show(); break; case R.id.radio_button4: Toast.makeText(MainTabActivity.this,"button4",Toast.LENGTH_SHORT).show(); break; } } }
