Start & Finish

1. Start ActivityB from ActivityA, write this in ActivityA.class:

 
AخA
Intent intent = new Intent(ActivityA.this, ActivityB.class);
startActivity(intent);

1. Want to finish an activity? Just call:

 
xxxxxxxxxx
finish();

启动活动的最佳写法

从活动A启动活动B，并传递数据给活动B

1. 在活动B添加：

    
   xxxxxxxxxx
   public static void actionStart(Context context, String data1, String data2) {
       Intent intent = new intent(context, B.class);
       intent.putExtra("data1", data1);
       intent.putExtra("data2", data2);
       context.startActivity(intent);
   }
   

2. 在活动A中：

    
   xxxxxxxxxx
   B.actionStart(A.this, "data1", "data2");
