android标签图标不显示 [英] android Tab icons don't show up

问题描述

现在我正试图让Tab布局工作。我已经做了一切，就像Android TabView教程一样，app运行正常，但问题是我没有看到任何我在ic_tab_artists.xml中定义它们的图标。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.

我想这与默认的主题或风格或其他什么有关。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.

我确信有足够的Android大师可以提供帮助，所以提前谢谢。

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

这是我的.xml定义使用图标：

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>

我的主要HolePage活动：

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

在不深入了解主题的情况下，我发现在应用程序清单中指定主题 @android：style / Theme.NoTitleBar 可以解决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>
