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)));
因为一个原因，我使用了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。
请帮帮我，谢谢~
例如 DiscoverActivity：
public class DiscoverActivity extends BaseActivity implements View.OnClickListener{
private RelativeLayout near, plate, search, rate, oil, two_dimension_code, rl_activity, coupon;

TabActivity现已弃用。要创建Tab您必须使用 Fragment 和 ViewPager .
以下是使用 Fragment 和 ViewPager 创建Tab的示例。
