You just need to call <code>finish()</code>

<pre><code>Intent intent = new Intent(this, NextActivity.class);
startActivity(intent);
finish();
</code></pre>

blocks|key|1074405|text|在清单中的活动上设置android:noHistory="true"将在将活动导航离开时从堆栈中删除该活动。请参阅here|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1074406|entityMap|0|LINK|mutability|MUTABLE|url|http://developer.android.com/guide/topics/manifest/activity-element.html#nohist^0|A|O|1L|4|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@$9|O|A|P|B|C]]|D|@$9|Q|A|R|1|S]]|E|$]]|$1|F|3|-4|5|6|7|T|8|@]|D|@]|E|$]]]|G|$H|$5|I|J|K|E|$L|M]]]]

Setting <code>android:noHistory="true"</code> on the activity in your manifest will remove an activity from the stack whenever it is navigated away from. see <a href="http://developer.android.com/guide/topics/manifest/activity-element.html#nohist" rel="noreferrer">here</a>

blocks|key|1074435|text|是的，您所需要做的就是在您想要关闭的任何活动中调用finish()。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1074436|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Yes, all you need to do is call finish() in any Activity you would like to close.

blocks|key|1289253|text|在初始化你的新意图之后，在每个“新活动”中写下这个->|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1289254|Intent+i+=+new+Intent(this,+yourClass.class);
startActivity(i);
finish();|code-block|syntax|javascript|1289255|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

Write this in each "new activity" after you initialized your new intent-> 

<pre><code>Intent i = new Intent(this, yourClass.class);
startActivity(i);
finish();
</code></pre>

blocks|key|1074485|text|您可以使用：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1074486|intent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);|code-block|syntax|javascript|1074487|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

you can use:

<pre><code>intent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
</code></pre>

blocks|key|1289287|text|您还可以在AndroidManifest.xml中将android:noHistory="true"添加到Activity标记中。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1289288|<activity
++++++++++++...
++++++++++++android:noHistory="true">
</activity>|code-block|syntax|javascript|1289289|entityMap^0|5|J|Q|O|1H|8|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@$9|N|A|O|B|C]|$9|P|A|Q|B|C]|$9|R|A|S|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|T|8|@]|D|@]|E|$I|J]]|$1|K|3|-4|5|6|7|U|8|@]|D|@]|E|$]]]|L|$]]

You can also add <code>android:noHistory="true"</code> to your <code>Activity</code> tag in <code>AndroidManifest.xml</code>.

<pre><code>&lt;activity
 ...
 android:noHistory="true"&gt;
&lt;/activity&gt;
</code></pre>

blocks|key|1074535|text|将此属性添加到清单文件中的活动中。android:noHistory="true“|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1074536|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Add this attribute to you activity in manifest file. 
android:noHistory="true"

blocks|key|1074639|text|您只需在启动新活动时使用以下代码。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1074640|startActivity(new+Intent(this,+newactivity.class));
finish();|code-block|syntax|javascript|1074641|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

You just need to use below code when launching the new activity.

<pre><code>startActivity(new Intent(this, newactivity.class));
finish();
</code></pre>

blocks|key|1289490|text|在Kotlin中，您可以使用以下代码|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1289491|startActivity(Intent(context,+newActivity::class.java))
finish()|code-block|syntax|javascript|1289492|或者你也可以使用这个|1289493|val+intent+=+Intent(context,+newActivity::class.java))
startActivity(intent)
finish()|1289494|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|N|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|O|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

In Kotlin, you may use this
<pre><code>startActivity(Intent(context, newActivity::class.java))
finish()
</code></pre>
Or you can use this also
<pre><code>val intent = Intent(context, newActivity::class.java))
startActivity(intent)
finish()
</code></pre>

In an given Android activity, I would like to start a new activity for the user at some point. Once they leave the first activity and arrive at the second, the first activity is stale and I want to remove it completely so it can not be accessed again from the back button.

How is the best way to accomplish this? How do I kill or destroy this activity immediately after the user has launched the new activity?

How to kill an Android activity when leaving it so that it cannot be accessed from the back button?

在给定的Android活动中，我想在某个时刻为用户启动一个新的活动。一旦他们离开第一个活动并到达第二个活动，第一个活动就过时了，我想完全删除它，这样就不能从后退按钮再次访问它。实现这一目标的最佳方法是什么？如何在用户启动新活动后立即终止或销毁此活动？
