android - 编辑 Tabview 背景颜色

Question

我应该如何更改 android TabActivity 中选项卡的背景颜色这是我的代码：

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    Resources res = getResources(); // Resource object to get Drawables
    final TabHost tabHost = getTabHost();  // The activity TabHost
    TabHost.TabSpec spec;  // Resusable TabSpec for each tab
    Intent intent;  // Reusable Intent for each tab

    // Create an Intent to launch an Activity for the tab (to be reused)
    intent = new Intent().setClass(this, ArtistsActivity.class);

    // Initialize a TabSpec for each tab and add it to the TabHost
    spec = tabHost.newTabSpec("artists").setIndicator("Artists",
                      res.getDrawable(R.drawable.ic_tab_artists))
                  .setContent(intent);
    tabHost.addTab(spec);


    // Do the same for the other tabs
    intent = new Intent().setClass(this, AlbumsActivity.class);
    spec = tabHost.newTabSpec("albums").setIndicator("Albums",
                      res.getDrawable(R.drawable.ic_tab_albums))
                  .setContent(intent);
    tabHost.addTab(spec);


    intent = new Intent().setClass(this, SongsActivity.class);
    spec = tabHost.newTabSpec("songs").setIndicator("Songs",
                      res.getDrawable(R.drawable.ic_tab_songs))
                  .setContent(intent);
    tabHost.addTab(spec);

    tabHost.getTabWidget().setBackgroundColor(Color.BLUE);
    tabHost.setCurrentTab(0);

}

如果我理解正确并且您想更改标签主机的颜色，而不是点击标签时加载的视图，您可以这样做

tabHost.getTabWidget().getChildAt(i).setBackgroundColor(Color.RED);
