mTabHost = getTabHost();
mTabHost.addTab(mTabHost.newTabSpec(TAB_NEWS).setIndicator(TAB_NEWS).setContent(new Intent(this, NewsActivity1.class)));
mTabHost.addTab(mTabHost.newTabSpec(TAB_BBS).setIndicator(TAB_BBS).setContent(new Intent(this, BBSActivity.class)));
mTabHost.addTab(mTabHost.newTabSpec(TAB_CATEGORY).setIndicator(TAB_CATEGORY).setContent(new Intent(this, CategoryActivity.class)));
mTabHost.addTab(mTabHost.newTabSpec(TAB_DISCOVER).setIndicator(TAB_DISCOVER).setContent(new Intent(this, DiscoverActivity.class)));
mTabHost.addTab(mTabHost.newTabSpec(TAB_MINE).setIndicator(TAB_MINE).setContent(new Intent(this, MineActivity.class)));
由于某个原因，我使用TabActivity，但系统的权限对话框无法在targetSdk23中显示。
例如：在NewsActivity，BBSActivity，CategoryActivity，DiscoverActivity，MineActivity中，都无法显示。
请帮助我，谢谢〜
例如DiscoverActivity：

TabActivity现已已弃用。要创建Tab，您必须使用Fragment和ViewPager创建它。
以下是使用Tab和Fragment创建ViewPager的示例。
请参阅此处的例子：http://www.truiton.com/2015/06/android-tabs-example-fragments-viewpager/
