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:
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”
