在Android应用程序中清除backstack按钮点击 [英] Clear backstack of application in android on button click

问题描述

我开发的应用程序中，我想明确的退出按钮的点击都是我背栈。
我已经搜索并尝试了多种解决方案，给出，但它不是为我工作。
请如果有人可以帮助我，这将是AP preciated。

我曾尝试下面的注销按钮，点击code

  intent.addFlags（Intent.FLAG_ACTIVITY_CLEAR_TOP）;
intent.addFlags（Intent.FLAG_ACTIVITY_NEW_TASK）;
 

和也试过以下清单文件code

 的android：launchMode =singleTop

我已经找到一个解决方案，并试图这又是为我工作得很好。

 意向意图=新意图（Settings.this，MainActivity.class）;
intent.setFlags（Intent.FLAG_ACTIVITY_CLEAR_TOP |
                Intent.FLAG_ACTIVITY_CLEAR_TASK |
                Intent.FLAG_ACTIVITY_NEW_TASK）;
startActivity（意向）;
完（）;
 

解决方案

  intent.setFlags（Intent.FLAG_ACTIVITY_NEW_TASK
                | Intent.FLAG_ACTIVITY_CLEAR_TASK）;
 

以上为我工作，但 Intent.FLAG_ACTIVITY_CLEAR_TASK 可从API 11

i have found one solution and tried this again was worked for me fine

Intent intent = new Intent(Settings.this, MainActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | 
                Intent.FLAG_ACTIVITY_CLEAR_TASK |
                Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
finish();

解决方案

intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK
                | Intent.FLAG_ACTIVITY_CLEAR_TASK);

above is working for me but Intent.FLAG_ACTIVITY_CLEAR_TASK is available from API 11
