android选项卡图标不显示 [英] android Tab icons don't show up

问题描述

现在我正在尝试让 Tab 布局正常工作.我已经完成了 Android TabView 教程中的所有操作，应用程序运行正常，但问题是我没有看到我在 ic_tab_artists.xml 中定义的任何图标.只有文字.

Right now I'm trying to get the Tab layout to work. I've done everything just like in Android TabView tutorial, app runs ok, but the problem is that I dont see any icons that I've defined them in ic_tab_artists.xml. There is text only.

我想这与默认主题或样式或其他主题有关.我试图改变它，但它根本没有帮助，仍然只是一个文本.

I guess it has something to do with theme that is default one or style or whatever. I've tried to change it but it didn't help at all, still just a text.

我正在使用 Android SDK v4.03.

I'm using Android SDK v4.03.

我确信有足够多的 Android 专家会提供帮助，所以提前致谢.

I'm sure there are enough Android gurus that will help, so thanks in advance.

这是我使用图标定义的 .xml:

This is my .xml defining using icons:

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


    <!-- When selected, use grey -->
<item android:drawable="@drawable/ic_tab_artists_grey" 
      android:state_selected="true" /> 


    <!-- When not selected (default), use white-->  
<item android:drawable="@drawable/ic_tab_artists_white" />

</selector>

还有我的主要 HolePage Activity:

And my main HolePage Activity:

@SuppressWarnings("deprecation")
public class HolePage extends TabActivity {


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.hole_page);

    //TABS      

    Resources res = getResources(); // Resource object to get Drawables
    TabHost tabHost = getTabHost();  // The activity TabHost
    TabHost.TabSpec spec;  // Reusable 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, HolePageScores.class);

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

    tabHost.addTab(spec);

    // Do the same for the other tabs - Info
    intent = new Intent().setClass(this, HolePageInfo.class);
    spec = tabHost.newTabSpec("info").setIndicator("Info",
                      res.getDrawable(R.drawable.tab_scores_icons))
                  .setContent(intent);
    tabHost.addTab(spec);

    // Do the same for the other tabs - Top
    intent = new Intent().setClass(this, HolePageTop.class);
    spec = tabHost.newTabSpec("top").setIndicator("Top",
                      res.getDrawable(R.drawable.tab_scores_icons))
                  .setContent(intent);
    tabHost.addTab(spec);

    // Do the same for the other tabs - Hole
    intent = new Intent().setClass(this, HolePageHole.class);
    spec = tabHost.newTabSpec("hole").setIndicator("Hole",
                      res.getDrawable(R.drawable.tab_scores_icons))
                  .setContent(intent);
    tabHost.addTab(spec);

    // Do the same for the other tabs - Par
    intent = new Intent().setClass(this, HolePagePar.class);
    spec = tabHost.newTabSpec("par").setIndicator("Par",
                      res.getDrawable(R.drawable.tab_scores_icons))
                  .setContent(intent);
    tabHost.addTab(spec);

    //Set default tab2
    tabHost.setCurrentTab(1);

}

}

推荐答案

在没有深入了解主题的情况下，我发现在应用程序中指定主题 @android:style/Theme.NoTitleBarmanifest 解决了这个问题，并且图标显示在选项卡中.

without knowing much in depth about themes, i have discovered that specifying the theme @android:style/Theme.NoTitleBar in the application manifest solves the issue and the icons show up in the tabs.

<application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@android:style/Theme.NoTitleBar" 
    >
    <!-- MANIFEST -->
</application>

希望，这会有所帮助！
