我做的应用程序TabHost甲酸，该选项卡具有默认的颜色显示，是否有可能改变默认的颜色，以我们自己的颜色？我有一些想法，从谷歌，

I am doing application with TabHost formate, The tab is displaying with Default color, is there any possibility to change default color to our own color.? I got some ideas from google,

tabHost.setOnTabChangedListener(new OnTabChangeListener(){
    @Override
    public void onTabChanged(String tabId) {
        // TODO Auto-generated method stub
         for(int i=0;i<tabHost.getTabWidget().getChildCount();i++)
            {
               tabHost.getTabWidget().getChildAt(i).setBackgroundColor(R.color.transparent); //unselected
            }
            tabHost.getTabWidget().getChildAt(tabHost.getCurrentTab()).setBackgroundColor(Color.parseColor("#000011")); // selected
    }

每当我这样做，我得到强制关闭错误。如果有改变背景颜色的想法的人，请指导我。

whenever i doing this i am getting force close error. if anyone having idea of changing background color, pls guide me.

推荐答案

您需要先更改默认appearence

You need first to change the default appearence

for(int i=0;i<tabHost.getTabWidget().getChildCount();i++)
    {
    if (i == 0) tabHost.getTabWidget().getChildAt(i).setBackgroundColor(Color.parseColor("#FFFFFF"));

    else tabHost.getTabWidget().getChildAt(i).setBackgroundColor(Color.parseColor("#7392B5"));
    }    

处理 onTabChanged 事件之前

tabHost.setOnTabChangedListener(new OnTabChangeListener(){
@Override
public void onTabChanged(String tabId) {
    // TODO Auto-generated method stub
     for(int i=0;i<tabHost.getTabWidget().getChildCount();i++)
        {
           tabHost.getTabWidget().getChildAt(i).setBackgroundColor(Color.parsecolor("#7392B5")); //unselected
        }
        tabHost.getTabWidget().getChildAt(tabHost.getCurrentTab()).setBackgroundColor(Color.parseColor("#FFFFFF")); // selected
}
});
