	        TabHost.TabSpec spec; 
	        Intent intent;  
 
	        // Create an Intent to launch an Activity for the tab (to be reused)
	        intent = new Intent().setClass(this, DriveActivity.class);
 
	        // Initialize a TabSpec for each tab and add it to the TabHost
	        spec = tabHost.newTabSpec("Tab1").setIndicator("Tab1",
	                          res.getDrawable(R.drawable.Tab1picture))
	                      .setContent(intent);
	        tabHost.addTab(spec);
 
	        // Do the same for the other tabs
	        intent = new Intent().setClass(this, LightsControlActivity.class);
	        spec = tabHost.newTabSpec("Tab2").setIndicator("Tab2",
	                          res.getDrawable(R.drawable.Tab2picture))
	                      .setContent(intent);
	        tabHost.addTab(spec);
 
	        intent = new Intent().setClass(this, NavigationActivity.class);
	        spec = tabHost.newTabSpec("Tab3").setIndicator("Tab3",
	                          res.getDrawable(R.drawable.Tab3picture))
	                      .setContent(intent);
	        tabHost.addTab(spec);
 
	        tabHost.setCurrentTab(2);
	    }
	}</code>

推荐答案

这实际上不是问题。这只是一个警告，告诉您正在使用的对象已被弃用。这并不意味着您不能再使用该对象。

It's not actually an issue. It's just a warning telling you that the object you are using has already been deprecated. It does not mean that you cannot use the object anymore.
