Question

默认背景为黑色，我希望它有不同的颜色。我认为答案在下面的XML中（但我可能是错的）。

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android"

    >
    <!-- When selected -->
    <item android:drawable="@drawable/login"
          android:state_selected="true"


        />
    <!-- When not selected -->
    <item android:drawable="@drawable/login"

        />
</selector>

这是Mainactivity

TabHost tabHost = getTabHost();


    // Tab for login
    TabSpec Login = tabHost.newTabSpec("Login");
    // setting Title and Icon for the Tab

    Login.setIndicator("", getApplicationContext().getResources().getDrawable(R.drawable.drawtab1));
    Intent LoginIntent = new Intent(this, Tab1Activity.class);
    LoginIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    Login.setContent(LoginIntent);

Answer 1

嗯，你可以像这样以编程方式改变它。

tabHost.getTabWidget().getChildAt(index).setBackgroundColor(Color.parseColor("#93BEDF"));
