如何减少标签的高度并在顶部对齐文本？

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>

解决方法:

只需尝试增加标签的高度即可：

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

对于文本对齐,请在xml布局中尝试以下操作：

android：gravity =“ top”或android：layout_gravity =“ top”
