Android可滑動Tab的3種實現方法

編輯：Android資訊

Android系統中有著各種各樣的Tab組件，並且大部分也都支持滑動，本文將結合代碼來實現3種方式的Android可滑動Tab組件，有需要的Android開發者可以收藏。

1. 第一種，使用 TabHost + ViewPager 實現

該方法會有一個Bug，當設置tabHost.setCurrentTab()為0時，ViewPager不顯示（准確的說是加載），只有點擊其他任意一個tab後才會加載。

有解的同學吼一聲~~~~~~~

布局：

<?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="match_parent"
    android:layout_height="match_parent" >
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical" >
        <TabWidget
            android:id="@android:id/tabs"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:gravity="right|center_vertical" />
        <FrameLayout
            android:id="@android:id/tabcontent"
            android:layout_width="match_parent"
            android:layout_height="match_parent" >
            <android.support.v4.view.ViewPager
                android:id="@+id/viewPager1"
                android:layout_width="match_parent"
                android:layout_height="match_parent" />
        </FrameLayout>
    </LinearLayout>
</TabHost>

2. 第二種，使用官方提供的方法 ActionBar + ViewPager 實現

該方法有兩個缺陷，或者說不是缺陷，只是我沒有找到解決的辦法。

第一，tab點上不是很靈敏，可能就是這麼設定的，為了防止頻繁加載吧，但是體驗稍稍不爽；

第二，ActionBar在最頂部，如果我的布局是：頂部一個帶返回按鈕的標題欄，中間是tab，底部是tabcontent，怎麼搞？
