Start new Activity and finish current one in Android?
提问by pixel
Currently I'm starting a new Activityand calling finishon a current one.
目前我正在开始一个新的Activity并呼吁finish当前的。
Is there any flag that can be passed to Intentthat enables finishing current Activitywithout a need to call finishmanually from code?
是否有任何标志可以传递到无需从代码手动调用Intent即可完成当前操作？Activityfinish
回答by Simon Dorociak
You can use finish()method or you can use:
您可以使用finish()方法，也可以使用：
android:noHistory="true"
And then there is no need to call finish()anymore.
然后就没有必要再打电话finish()了。
<activity android:name=".ClassName" android:noHistory="true" ... />

Use finishlike this:
finish像这样使用：
Intent i = new Intent(Main_Menu.this, NextActivity.class);
finish(); //Kill the activity from which you will go to next activity
startActivity(i);
FLAG_ACTIVITY_NO_HISTORYdoes the opposite. New activity is not saved in history, whereas OP wants previous Activity being finished.
FLAG_ACTIVITY_NO_HISTORY相反。新活动不会保存在历史记录中，而 OP 想要完成之前的活动。

FLAG_ACTIVITY_NO_HISTORY when starting the activity you wish to finish after the user goes to another one.
FLAG_ACTIVITY_NO_HISTORY 在用户转到另一个活动后开始您希望完成的活动时。
