我目前的工作::
我设计了一个标签活动,底部有四个标签
快照
BreakfastLunchDinnerIndividualListOfItems.java
public class BreakfastLunchDinnerIndividualListOfItems extends TabActivity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.breakfast_lunch_dinner_individual_list_of_items);
Resources res = getResources(); // Resource object to get Drawables
TabHost tabHost = getTabHost(); // The activity TabHost
TabHost.TabSpec spec; // Reusable TabSpec for each tab
Intent intent; // Reusable Intent for each tab
// Create an Intent to launch an Activity for the tab (to be reused)
intent = new Intent().setClass(this, BLD_IndividualListOfItems_Starters.class);
spec = tabHost.newTabSpec("STARTERS").setIndicator("Starters").setContent(intent);
tabHost.addTab(spec);
// Do the same for the other tabs
intent = new Intent().setClass(this, BLD_IndividualListOfItems_MainCourse.class);
spec = tabHost.newTabSpec("MAIN_COURSE").setIndicator("Main Course").setContent(intent);
tabHost.addTab(spec);
intent = new Intent().setClass(this, BLD_IndividualListOfItems_SideCourse.class);
spec = tabHost.newTabSpec("SIDE_COURSE").setIndicator("Side course").setContent(intent);
tabHost.addTab(spec);
intent = new Intent().setClass(this, BLD_IndividualListOfItems_Others.class);
spec = tabHost.newTabSpec("OTHERS").setIndicator("Others").setContent(intent);
tabHost.addTab(spec);
intent = new Intent().setClass(this, BLD_IndividualListOfItems_Desert.class);
spec = tabHost.newTabSpec("DESERT").setIndicator("Deserts").setContent(intent);
tabHost.addTab(spec);
//set tab which one you want open first time 0 or 1 or 2
tabHost.setCurrentTab(0);
}
}

答案 0 :(得分:2)
当您在标签窗口小部件中定义layout_width="fill_parent"
时,您说所有标签的大小均匀,并填充其各自的父标签。但是,在您的情况下,这些选项卡中的内容不能保证是均匀的。因此,您需要在每个选项卡中创建一个新的TextView
来保存文本。这将允许特定于每个标签内容的内容包装。
我提供了一个示例XML来澄清:
<?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">
<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="0dip"
android:layout_weight="1"/>
<TabWidget
android:id="@android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="0"
android:layout_marginBottom="-4dp">
<TextView
android:tag="tab0"
android:text="Starters"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
/>
<TextView
android:tag="tab1"
android:text="Main Course"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
/>
<TextView
android:tag="tab2"
android:text="Side Course"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
/>
<TextView
android:tag="tab2"
android:text="Others"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
/>
<TextView
android:tag="tab2"
android:text="Desert"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
/>
</TabWidget>
</LinearLayout>
我相信这也需要对你的java稍作修改。
