java - 如何删除android中的tabStrip？

Question

我想删除选项卡颜色条。我尝试了 setStripEnabled(false); 但这不起作用。还在 xml 代码中尝试了 android:tabStripEnabled="false" 。选项卡条仍然显示在选项卡栏上。有人可以告诉我如何删除标签栏中出现的蓝色 strip 。

JAVA CODE:

public class TabsFragmentActivity extends FragmentActivity implements TabHost.OnTabChangeListener {
private TabHost mTabHost;
private HashMap mapTabInfo = new HashMap();
private TabInfo mLastTab = null;

private class TabInfo {
     private String tag;
     private Class clss;
     private Bundle args;
     private Fragment fragment;
     TabInfo(String tag, Class clazz, Bundle args) {
         this.tag = tag;
         this.clss = clazz;
         this.args = args;
     }

}

class TabFactory implements TabContentFactory {

    private final Context mContext;

    /**
     * @param context
     */
    public TabFactory(Context context) {
        mContext = context;
    }

    /** (non-Javadoc)
     * @see android.widget.TabHost.TabContentFactory#createTabContent(java.lang.String)
     */
    public View createTabContent(String tag) {
        View v = new View(mContext);
        v.setMinimumWidth(0);
        v.setMinimumHeight(0);
        return v;
    }

}
/** (non-Javadoc)
 * @see android.support.v4.app.FragmentActivity#onCreate(android.os.Bundle)

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    // Step 1: Inflate layout
    setContentView(R.layout.tabs_layout);
    // Step 2: Setup TabHost
    initialiseTabHost(savedInstanceState);
    if (savedInstanceState != null) {
        mTabHost.setCurrentTabByTag(savedInstanceState.getString("tab")); //set the tab as per the saved state

    }
}

/** (non-Javadoc)
 * @see android.support.v4.app.FragmentActivity#onSaveInstanceState(android.os.Bundle)
 */
protected void onSaveInstanceState(Bundle outState) {
    outState.putString("tab", mTabHost.getCurrentTabTag()); //save the tab selected
    super.onSaveInstanceState(outState);
}

/**
 * Step 2: Setup TabHost
 */
private void initialiseTabHost(Bundle args) {
    mTabHost = (TabHost)findViewById(android.R.id.tabhost);
    mTabHost.setup();

    TabInfo tabInfo = null;
    Resources res = getResources();

    TabsFragmentActivity.addTab(this, this.mTabHost, this.mTabHost.newTabSpec("Tab1").setIndicator("",res.getDrawable(R.drawable.ic_launcher)), ( tabInfo = new TabInfo("Tab1", Tab1Fragment.class, args)));
    this.mapTabInfo.put(tabInfo.tag, tabInfo);
    TabsFragmentActivity.addTab(this, this.mTabHost, this.mTabHost.newTabSpec("Tab2").setIndicator("",res.getDrawable(R.drawable.ic_launcher)), ( tabInfo = new TabInfo("Tab2", Tab2Fragment.class, args)));
    this.mapTabInfo.put(tabInfo.tag, tabInfo);
    TabsFragmentActivity.addTab(this, this.mTabHost, this.mTabHost.newTabSpec("Tab3").setIndicator("",res.getDrawable(R.drawable.ic_launcher)), ( tabInfo = new TabInfo("Tab3", Tab3Fragment.class, args)));
    this.mapTabInfo.put(tabInfo.tag, tabInfo);

    // Default to first tab
    this.onTabChanged("Tab1");
    //
    mTabHost.setOnTabChangedListener(this);
}

/**

                ft.add(R.id.realtabcontent, newTab.fragment, newTab.tag);

        mLastTab = newTab;
        ft.commit();
        this.getSupportFragmentManager().executePendingTransactions();

将这些行添加到您的样式 xml 文件中

<style name="AppTheme" parent="AppBaseTheme">
    <item name="android:tabWidgetStyle">@style/LightTabWidget</item>
</style>

<style name="LightTabWidget" parent="@android:style/Widget.TabWidget">
    <item name="android:tabStripEnabled">false</item>
</style>
