Intent.FLAG_ACTIVITY_CLEAR_TOP不删除该活动栈 [英] Intent.FLAG_ACTIVITY_CLEAR_TOP doesn't deletes the activity stack

问题描述

我开发的，我想关闭按钮点击整个应用程序的应用。我知道，在Android中，我们不应该考虑到由于Android的自动执行此<一个关闭应用程序href="http://stackoverflow.com/questions/2033914/quitting-an-application-is-that-frowned-upon?lq=1">Quitting一个应用程序 - 这是令人难以接受的？但我却想收我的应用程序。

I am developing the application in which i want to close whole application on button click. I know in android we should not think about to close the application because android does that automatically from this Quitting an application - is that frowned upon?. but yet i want to close my application.

所以我在做什么，收的应用程序是我使用 Intent.FLAG_ACTIVITY_CLEAR_TOP 标志删除活动堆栈。

So what i am doing to close application is i am using Intent.FLAG_ACTIVITY_CLEAR_TOP flag to delete the activity stack.

Intent intent = new Intent(Activity3.this, FinishActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(intent);
finish();

和中的onCreate FinishActivity.class 我打电话 this.finish（），但应用程序不会被关闭和previous活动被​​重新打开。

And in onCreate of FinishActivity.class i am calling this.finish() but application is not get closed and previous activity gets reopened.

FinishActivity.class

FinishActivity.class

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    this.finish();
}

更新：

下面是该方案

MainActivity->Activity2->Activity3->FinishActivity

下面活性2 是在完成活动后，被打开了。

Here Activity2 is gets opened after finishing the activity.

我如何实现这一目标？任何意见和建议将成为AP preciated。

How do i achieve this? Any idea and suggestion will be appreciated.

感谢和放大器;问候

推荐答案

使用此 -

 Intent intent = new Intent(Activity3.this, FinishActivity.class);
 intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);
 intent.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
 startActivity(intent);
 finish();

只是走一个例子......做你的项目需要相应的东西 -

just taking an example...do it accordingly what your project needs--

我服用三Activity类A，B和C..and我已经Activity..If你想要然后通过返回按钮，你可以去到previous活动，当应用在C类的视图关闭按钮您preSS关闭按钮，那么你将退出从apps..have看看 -

I am taking three Activity class A, B and C..and i have applied close button on the view of class C Activity..If you want then by Back button you can go to the previous Activity and when you press close button then you would exit from apps..have a look--

public class AActivity extends Activity {

  /** Called when the activity is first created. */
  @Override
   public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    Intent i = new Intent(this, B.class);
    startActivityForResult(i, 1);
}

@Override
protected void onActivityResult(final int requestCode,
        final int resultCode, final Intent intent) {
    super.onActivityResult(requestCode, resultCode, intent);

    if (resultCode == 5) {
        finish();
    }
}

}

取隔壁班的活动 -

Take next class activity--

   public class B extends Activity {
    /** Called when the activity is first created. */
   @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.b);

    Intent i = new Intent(this, C.class);
    startActivityForResult(i, 2);
}

@Override
protected void onActivityResult(final int requestCode,
        final int resultCode, final Intent intent) {
    super.onActivityResult(requestCode, resultCode, intent);

    if (resultCode == 5) {
        setResult(5);
        finish();
    }
}

}

取最后一项活动 -

Take last activity--

    public class C extends Activity {
   /** Called when the activity is first created. */
   @Override
   public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.c);
}

    // close button..set by xml view..you can set it by button listener.
public void close(View v) {
    setResult(5);
    finish();
}

}
