Android 中 TabHost與ViewPager結合實現(xiàn)首頁導航效果
今天發(fā)的是TabHost結合ViewPager實現(xiàn)首頁底部導航的效果,雖然說網上有很多這樣的Demo,不過呢,我還是要把自己練習寫的發(fā)出來,沒錯!就是這么任性;
先上效果圖,如下:

代碼里面有注釋,就不過多解釋了,說幾點需要注意的問題
1:TabHost 、TabWidget、FrameLayout一定添加id這個屬性,否則會報錯
android:id=”@android:id/tabhost”
android:id=”@android:id/tabcontent”
android:id=”@android:id/tabs”
這個屬性是固定的。
2:ViewPager的適配器要繼承PagerAdapter,別整錯咯;
布局文件xml:
