使用setOnTabChangedListener（TabHost.OnTabChangeListener L）上TabHost：

  myTabHost.setOnTabChangedListener（新TabHost.OnTabChangeListener（）{
  @覆盖
  公共无效onTabChanged（字符串tabId）{
    INT标签= myTabHost.getCurrentTab（）;
    。myTabHost.getTabWidget（）getChildAt（标签）.setBackgroundColor（Color.CYAN）;
  }
}）;
 

也许还有一个更简单的方法，我没有使用它之前;）

I came from objective-c and I am an Android newbie. I am using following method that intends to change tabColor for index 0. But I would like to change default grey tab when selected. Thank you.

mTabHost.getTabWidget().getChildAt(0).setBackgroundColor(Color.CYAN);

Use setOnTabChangedListener(TabHost.OnTabChangeListener l) on the TabHost:

myTabHost.setOnTabChangedListener(new TabHost.OnTabChangeListener(){
  @Override
  public void onTabChanged(String tabId) {
    int tab = myTabHost.getCurrentTab();
    myTabHost.getTabWidget().getChildAt(tab).setBackgroundColor(Color.CYAN);
  }
});

Maybe there is a simpler way, i dont have use it before ;)
