- TabActivity的使用(知识拓展)

- 创建CleanActivity, 继承TabActivity

                      

public class CleanActivity extends TabActivity {
			
				@Override
				protected void onCreate(Bundle savedInstanceState) {
					super.onCreate(savedInstanceState);
					setContentView(R.layout.activity_clean_base);
			
					TabHost host = getTabHost();
			
					TabSpec tab1 = host.newTabSpec("缓存清理").setIndicator("缓存清理");
					TabSpec tab2 = host.newTabSpec("SD卡清理").setIndicator("SD卡清理");
			
					tab1.setContent(new Intent(this, CleanCacheActivity.class));
					tab2.setContent(new Intent(this, CleanSdcardActivity.class));
			
					host.addTab(tab1);
					host.addTab(tab2);
				}
			}

    - 编写布局文件

			
			
			    
	
					//内容体
			        
			        
	
					//标签体
