我已经打印了选项卡在滑动选项卡类中的文本,但它们不是大写的.我环顾四周,没有调用toUpperCase方法.

以下是设置文本的类中的代码：

private void populateTabStrip() {
        final PagerAdapter adapter = mViewPager.getAdapter();
        final View.OnClickListener tabClickListener = new TabClickListener();

        for (int i = 0; i < adapter.getCount(); i++) {
            View tabView = null;
            TextView tabTitleView = null;

            if (mTabViewLayoutId != 0) {
                // If there is a custom tab view layout id set,try and inflate it
                tabView = LayoutInflater.from(getContext()).inflate(mTabViewLayoutId,mTabStrip,false);
                tabTitleView = (TextView) tabView.findViewById(mTabViewTextViewId);
            }

            if (tabView == null) {
                tabView = createDefaultTabView(getContext());
            }

            if (tabTitleView == null && TextView.class.isInstance(tabView)) {
                tabTitleView = (TextView) tabView;
            }

            if (mDistributeEvenly) {
                LinearLayout.LayoutParams lp = (LinearLayout.LayoutParams) tabView.getLayoutParams();
                lp.width = 0;
                lp.weight = 1;
            }

            tabTitleView.setText(adapter.getPageTitle(i));
            tabTitleView.setTextColor(getResources().getColor(R.color.da_blue));
            tabView.setOnClickListener(tabClickListener);
            String desc = mContentDescriptions.get(i,null);
            if (desc != null) {
                tabView.setContentDescription(desc);
            }

            mTabStrip.addView(tabView);
            if (i == mViewPager.getCurrentItem()) {
                tabView.setSelected(true);
            }
        }
    }

我敢肯定我可以通过一种风格来做,但实际上不确定使用哪种风格.这就是我的风格：

<resources>

    <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <item name="android:actionBarTabTextStyle">@style/ActionBarTabTextStyle.Tabtheme</item>
        <item name="actionBarTabTextStyle">@style/ActionBarTabTextStyle.Tabtheme</item>
    </style>


    <style name="ActionBarTabTextStyle.Tabtheme" parent="@android:style/Widget.Holo.ActionBar.TabText">
        <item name="android:textAllCaps">false</item>
    </style>
</resources>
