采用Android的标签与意见，而不是活动的例子？

问题描述

Android开发TabWidget教程说以下内容：

The Android Developers TabWidget tutorial says the following:

你可以实现两种方法之一为选项卡的内容：使用标签交换意见相同的活动中，或使用标签完全独立的活动之间改变

"You can implement your tab content in one of two ways: use the tabs to swap Views within the same Activity, or use the tabs to change between entirely separate activities."

本教程继续演示如何使用标签有独立的活动。我一直无法找到使用标签与同一活动中的不同意见的一个例子。我宁愿不重新发明这个特殊的轮子，所以我希望这里有人知道如何做到这一点，并能在感谢线索我！

The tutorial goes on to demonstrate how you can use tabs with separate Activities. I have been unable to find an example of using tabs with different Views within the same Activity. I would rather not re-invent this particular wheel, so I am hoping someone here knows how this is done and can clue me in. Thanks!

推荐答案

我觉得每次通过在视图选项卡的.setContent方法要使用：

I think in the .setContent method of each tab you pass in the view you wish to use:

TabHost.TabSpec spec1 = tabs.newTabSpec("tag1");
spec1.setContent(R.id.AnalogClock01);
spec1.setIndicator("Analog Clock");

下面是一个例子，我发现了一段时间回来：

Here's an example I found awhile back:

    <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>

  <TabHost android:id="@+id/TabHost01" android:layout_width="wrap_content" android:layout_height="wrap_content">
    <TabWidget android:id="@android:id/tabs" android:layout_width="wrap_content" android:layout_height="wrap_content" />
    <FrameLayout android:id="@android:id/tabcontent" android:layout_width="wrap_content" android:layout_height="wrap_content" android:paddingTop="65px">
      <AnalogClock android:id="@+id/AnalogClock01" android:layout_width="wrap_content" android:layout_height="wrap_content"></AnalogClock>
      <DigitalClock android:text="DigitalClock01" android:id="@+id/DigitalClock01" android:layout_width="wrap_content" android:layout_height="wrap_content"></DigitalClock>
    </FrameLayout>
  </TabHost>
</LinearLayout>

和在Java code表示本实施例是如下：

And the Java code for this example is as follows:

import android.app.Activity;
import android.os.Bundle;
import android.widget.TabHost;

public class tabexample extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        TabHost tabs = (TabHost)findViewById(R.id.TabHost01);

        tabs.setup();

        TabHost.TabSpec spec1 = tabs.newTabSpec("tag1");

        spec1.setContent(R.id.AnalogClock01);
        spec1.setIndicator("Analog Clock");

        tabs.addTab(spec1);

        TabHost.TabSpec spec2 = tabs.newTabSpec("tag2");
        spec2.setContent(R.id.DigitalClock01);
        spec2.setIndicator("Digital Clock");

        tabs.addTab(spec2);
    }
}
