Question

  TabWidget tw = getTabWidget();

   for (int i = 0; i < tw.getChildCount(); i++) {
        View v = tw.getChildAt(i);


         v.setBackgroundColor(Color.parseColor("#666666"));
    }
    tw.getChildAt(0).setBackgroundColor(Color.parseColor("#B21206"));

There are two tabs in my activity. This code keeps the color of the first tab fixed to "RED" but does not make the second tab change to "RED" when clicked. what changes should be done in the code?

Answer 1

在您的表态中教授这一守则。这对你们可能有用......

    for(int i = 0; i < getTabWidget().getChildCount(); i++)
    {
        if(getTabWidget().getChildAt(i).isSelected())
        {
            //selected tab
            getTabWidget().getChildAt(i).setBackgroundColor(Color.RED);
        }
        else
        {
            //un-selected tabs
            getTabWidget().getChildAt(i).setBackgroundColor(Color.GREEN);
        }
    }

利用xml bg 挑选人完成你的任务,这是你想要做的更好办法。

如果你想在法典中尝试,

pass your tab host in settabColor(yourtabhost);

public static void setTabColor(TabHost tabhost) {
    for(int i=0;i<tabhost.getTabWidget().getChildCount();i++)
    {
        tabhost.getTabWidget().getChildAt(i).setBackgroundColor(Color.parseColor("#FF0000")); //unselected
    }
    tabhost.getTabWidget().getChildAt(tabhost.getCurrentTab()).setBackgroundColor(Color.parseColor("#0000FF")); // selected
}
