如何缩小 Tab 的高度并且把 text 调整到最顶端？

Question

我怎样才能减少tab高度和文本对齐选项卡上吗?

import android.app.TabActivity;
import android.content.Intent;
import android.os.Bundle;
import android.widget.TabHost;

public class MessagesTabs extends TabActivity{

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.messages_tabs);

        //Resources res = getResources(); // Resource object to get Drawables
        TabHost tabHost = getTabHost();  // The activity TabHost
        TabHost.TabSpec spec;  // Resusable 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, GetMessages.class);

        // Initialize a TabSpec for each tab and add it to the TabHost
        spec = tabHost.newTabSpec("inbox").setIndicator("Inbox")
        .setContent(intent);
        tabHost.addTab(spec);

        // Do the same for the other tabs
        intent = new Intent().setClass(this, GetConversations.class);
        spec = tabHost.newTabSpec("conversation").setIndicator("Conversation")
        .setContent(intent);
        tabHost.addTab(spec);
        /*
        intent = new Intent().setClass(this, SongsActivity.class);
        spec = tabHost.newTabSpec("songs").setIndicator("Songs",
                          res.getDrawable(R.drawable.ic_tab_songs))
                      .setContent(intent);
        tabHost.addTab(spec);*/

        tabHost.setCurrentTab(0);
    }
}

xml 文件：

<?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"
        >
        <TabWidget          
            android:id="@android:id/tabs"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content" />
        <FrameLayout
            android:id="@android:id/tabcontent"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
             />
    </LinearLayout>
</TabHost>

使用下面的代码来增加 tabs 的高度。

 tabHost.getTabWidget().getChildAt(index).getLayoutParams().height =(int) height;

对于文本的对齐，在 xml 布局中添加：
android:gravity="top" 或者 android:layout_gravity="top"
