选项卡使用方法二(Android学习随笔十三)
1、不继承TabActivity
2、在布局件中定义TabHost
注意:TabWidget的id必须是@android:id/tabs,FrameLayout的id必须是@android:id/tabcontent。
java代码:
package yc.demo;
import android.app.Activity;
import android.os.Bundle;
import android.widget.TabHost;
import android.widget.TabHost.TabSpec;
public class TabhostDemo1Activity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.demo1);
//获取到TabHost
TabHost tabHost = (TabHost)this.findViewById(R.id.tabs);
tabHost.setup();
//获取一个新的TabHost.TabSpec,并关联到当前tabHost
//参数:所需的选项卡标签
TabSpec pSpes = tabHost.newTabSpec("parent");
pSpes.setIndicator("父类", this.getResources().getDrawable(R.drawable.msg_icon));
pSpes.setContent(R.id.textView1);
TabSpec subSpec = tabHost.newTabSpec("sub");
subSpec.setIndicator("子类",this.getResources().getDrawable(R.drawable.at_icon));
subSpec.setContent(R.id.textView2);
//向tabHost中添加选项卡
tabHost.addTab(pSpes);
tabHost.addTab(subSpec);
}
}
xml布局文件:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<TabHost android:id="@+id/tabs"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<TabWidget android:id="@android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>
<FrameLayout android:id="@android:id/tabcontent"
android:layout_height="fill_parent"
android:layout_width="fill_parent">
<TextView android:id="@+id/textView1"
android:layout_height="fill_parent"
android:layout_width="fill_parent"
android:text="parent"/>
<TextView android:id="@+id/textView2"
android:layout_height="fill_parent"
android:layout_width="fill_parent"
android:text="sub"/>
</FrameLayout>
</LinearLayout>
</TabHost>
</LinearLayout>
提示:选项卡的显示顺序是根据你添加选项卡的顺序定的
