Android 设置viewPager选项卡文本
从viewPager片段中的后台任务获取数据后，我想设置viewPager选项卡文本。 现在发生了什么：我在viewpager中有3个片段。每个片段都在运行一个异步任务，我用它的结果来更新viewpager选项卡文本。但是，viewpager会在fragment的异步任务完成之前设置选项卡文本。我无法处理viewpager和片段之间的通信 代码： SlidingTab.xml（Viewpager xml）：Android 设置viewPager选项卡文本,android,android-fragments,android-viewpager,android-tablayout,Android,Android Fragments,Android Viewpager,Android Tablayout,从viewPager片段中的后台任务获取数据后，我想设置viewPager选项卡文本。 现在发生了什么：我在viewpager中有3个片段。每个片段都在运行一个异步任务，我用它的结果来更新viewpager选项卡文本。但是，viewpager会在fragment的异步任务完成之前设置选项卡文本。我无法处理viewpager和片段之间的通信 代码： SlidingTab.xml（Viewpager xml）： <LinearLayout xmlns:android="http://schem
