Question

之前我在tabhost中有5个标签，使用旧的2.2 SDK和Activity组。现在我需要将它们更改为ActionBar及其tabbar，具有相似的外观。

我之前拥有的是这样的： Before

我现在拥有的是这样的：

now

我无法弄清楚如何自定义操作栏的标签以显示与之前相同的内容。我不需要滚动标签，只需要固定，旧时尚。

我使用Support Libiray，项目中的v4和v7都支持最高sdk 8，这是必需的。

我尝试过挖掘风格，但到目前为止还没有运气。我可以改变颜色，但不能改变宽度。而且我似乎需要使用AppComp主题或其desenct来使应用程序在旧设备上运行。

任何帮助都将非常感谢...谢谢！

我已将其添加到屏幕底部，您可以将其更改为您的要求

MainActivity.java

public class MainActivity extends Activity {
public static final String M_CURRENT_TAB = "M_CURRENT_TAB";

    mTabHost = (TabHost) findViewById(android.R.id.tabhost);
    mTabHost.setup();

    if (savedInstanceState != null) {
        mCurrentTab = savedInstanceState.getString(M_CURRENT_TAB);
        initializeTabs();
        mTabHost.setCurrentTabByTag(mCurrentTab);
