如何设置FragmentTabHost标签文本颜色

Question

如何设置FragmentTabHost标签文本颜色。我尝试了下面的代码，但它不起作用。

((TextView) mTabHost.getCurrentTabView() 
       .findViewById(android.R.id.title)).setTextColor(0xFFFFFFFF); 

它给NPE说它找不到TextView。

Answer 1

这是一个有点棘手。我用下面的代码，它为我工作。

for (int i = 0; i < tabhost.getTabWidget().getChildCount(); i++) { 

     final TextView tv = (TextView) tabhost.getTabWidget().getChildAt(i) 
       .findViewById(android.R.id.title); 

      // Look for the title view to ensure this is an indicator and not a divider.(I didn't know, it would return divider too, so I was getting an NPE) 
     if (tv == null) 
      continue; 
     else 
      tv.setTextColor(0xFFFFFFFF); 
}

let's try this : 
for example when you add your tab make your Indicator : 

    TextView view = .... 
    vew.setTextColor(...) 

然后setIndicator与您的自定义视图：

mTabHost.addTab(mTabHost.newTabSpec("simple").setIndicator(view), 
        FragmentStackSupport.CountingFragment.class, null);
