TabHost效果
public class MainActivity extends FragmentActivity{
//定义FragmentTabHost对象
private FragmentTabHost mTabHost;
//定义一个布局
private LayoutInflater layoutInflater;
//定义数组来存放Fragment界面
@SuppressWarnings("rawtypes")
private Class fragmentArray[] = {InspectFragment.class,ExecuteFragment.class,TaskFragment.class,ExitFragment.class};
//定义数组来存放按钮图片
private int mImageViewArray[] = {R.drawable.tab_more_btn,R.drawable.tab_home_btn,R.drawable.tab_selfinfo_btn,R.drawable.tab_message_btn};
public void onCreate(Bundle savedInstanceState) {
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
super.onCreate(savedInstanceState);
setContentView(R.layout.main_tab_layout);
initView();
}
/**
* 初始化组件
*/
private void initView(){
//实例化布局对象
layoutInflater = LayoutInflater.from(this);
//实例化TabHost对象,得到TabHost
mTabHost = (FragmentTabHost)findViewById(android.R.id.tabhost);
mTabHost.setup(this, getSupportFragmentManager(), R.id.realtabcontent);
//得到fragment的个数
int count = fragmentArray.length;
for(int i = 0; i < count; i++){
//为每一个Tab按钮设置图标、文字和内容
TabSpec tabSpec = mTabHost.newTabSpec(i+"").setIndicator(getTabItemView(i));
//将Tab按钮添加进Tab选项卡中
mTabHost.addTab(tabSpec, fragmentArray[i], null);
}
}
/**
* 给Tab按钮设置图标和文字
*/
private View getTabItemView(int index){
View view = layoutInflater.inflate(R.layout.main_tab_item, null);
TextView tab_item_view = (TextView) view.findViewById(R.id.tab_item_view);
tab_item_view.setBackgroundResource(mImageViewArray[index]);
return view;
}
}
注意在Fragment导包的时候要导import android.support.v4.app.Fragment;
图标用背景选择器:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/xpd" android:state_selected="true"/>
<item android:drawable="@drawable/pd"/>
</selector>
布局文件
<android.support.v4.app.FragmentTabHost
android:id="@android:id/tabhost"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<FrameLayout
android:id="@android:id/tabcontent"
android:layout_width="0dp"
android:layout_height="50dp"
android:layout_weight="0" />
</android.support.v4.app.FragmentTabHost>
<FrameLayout
android:id="@+id/realtabcontent"
android:layout_width="fill_parent"
android:layout_height="0dip"
android:layout_weight="1" />
