protected void onCreate(Bundle savedInstanceState) 
{
  super.onCreate(savedInstanceState);
  setContentView(R.layout.splash);

  TabHost tabHost = (TabHost)findViewById(android.R.id.tabhost);

  TabSpec homeTabSpec = tabHost.newTabSpec("tid1");
  TabSpec videoTabSpec = tabHost.newTabSpec("tid1");
  TabSpec aboutUsTabSpec = tabHost.newTabSpec("tid1");

  homeTabSpec.setIndicator("Home").setContent(new Intent(this,FirstActivity.class));
  homeTabSpec.setIndicator("tid1",getResources().getDrawable(R.drawable.home));

  videoTabSpec.setIndicator("Video").setContent(new Intent(this,VideoWeb.class));
  videoTabSpec.setIndicator("tid1",getResources().getDrawable(R.drawable.videos));

  aboutUsTabSpec.setIndicator("About Us").setContent(new     Intent(this,AboutWeb.class));
  aboutUsTabSpec.setIndicator("tid1",getResources().getDrawable(R.drawable.aboutus));

  tabHost.addTab(homeTabSpec);
  tabHost.addTab(videoTabSpec);
  tabHost.addTab(aboutUsTabSpec);

Answer 1

如果您的xml布局中没有定义TabActivity，则应调用tabHost.setup()向其中添加任何内容。

所以它应该是：

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

TabHost没有显示任何内容
