Activity活动的最佳实践

1 public class BaseActivity extends Activity
2 {
3     @Override
4     protected void onCreate(Bundle savedInstanceState)
5     {
6         super.onCreate(savedInstanceState);
7         Log.e("当前活动:", getClass().getSimpleName());//获取当前活动的类名
8     }
9 }

 1 public class ActivityController
 2 {
 3     private static List<Activity> activities = new LinkedList<>();
 4 
 5     public static void addActivity(Activity activity)
 6     {
 7         activities.add(activity);
 8     }
 9 
10     public static void removeActivity(Activity activity)
11     {
12         activities.remove(activity);
13     }
14 
15     public static void finishAll()
16     {
17         for (Activity activity : activities)
18         {
19             if (!activity.isFinishing())
20             {
21                 activity.finish();
22             }
23         }
24     }
25 }

 5     {
 6         super.onCreate(savedInstanceState);
 7         Log.e("当前活动:", getClass().getSimpleName());//获取当前活动的类名
 8         ActivityController.addActivity(this);//将活动添加到集合中
 9     }
10 
11     @Override
12     protected void onDestroy()
13     {
14         super.onDestroy();
15         ActivityController.removeActivity(this);////将活动从集合中移除
16     }
17 }

 1 public class SecondActivity extends BaseActivity
 2 {
 3     /**
 4      * 启动活动的最佳写法
 5      * 需要几个参数,传几个参数
 6      */
 7     public static void actionStart(Context context, String data1, String data2)
 8     {
 9         Intent intent = new Intent(context, SecondActivity.class);
10         intent.putExtra("param1", data1);
11         intent.putExtra("param2", data2);
12         context.startActivity(intent);
13     }
14     //.............
15 }

1 btn.setOnClickListener(new View.OnClickListener()
2         {
3             @Override
4             public void onClick(View v)
5             {
6                 SecondActivity.actionStart(FirstActivity.this, "要传递的数据1", "要传递的数据1");
7             }
8         });
