blocks|key|849962|text|这是一个刷新按钮方法，但它在我的应用程序中工作得很好。在finish()中，您将杀死实例|type|unstyled|depth|inlineStyleRanges|entityRanges|data|849963|public+void+refresh(View+view){++++++++++//refresh+is+onClick+name+given+to+the+button

This is a refresh button method, but it works well in my application. in finish() you kill the instances

<pre><code>public void refresh(View view){ //refresh is onClick name given to the button
 onRestart();
}

@Override
protected void onRestart() {

 // TODO Auto-generated method stub
 super.onRestart();
 Intent i = new Intent(lala.this, lala.class); //your class
 startActivity(i);
 finish();

}
</code></pre>

blocks|key|850002|text|最简单的方法是调用onCreate(null);，您的活动将像新的一样。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|850003|entityMap^0|9|F|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|K|8|@]|D|@]|E|$]]]|G|$]]

The easiest way is to call <code>onCreate(null);</code> and your activity will be like new.

blocks|key|850016|text|您可以使用：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|850017|startActivity(MyClass.this,+MyClass.class).setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);|code-block|syntax|javascript|850018|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>startActivity(MyClass.this, MyClass.class).setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
</code></pre>

blocks|key|850058|text|在活动中，您可以调用recreate()来“重新创建”活动(11%2B接口)|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|850059|entityMap^0|A|A|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|K|8|@]|D|@]|E|$]]]|G|$]]

In an activity you can call <code>recreate()</code> to "recreate" the activity
(API 11+)

blocks|key|633705|text|您可以尝试这样做：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|633706|++++++++CookieSyncManager.createInstance(this);+++++++++
++++++++CookieManager+cookieManager+=+CookieManager.getInstance();++++++++

You can Try this:

<pre><code> CookieSyncManager.createInstance(this); 
 CookieManager cookieManager = CookieManager.getInstance(); 
 cookieManager.removeAllCookie(); 
 Intent intent= new Intent(YourCurrent.this, YourCurrent.class);
 intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_NEW_TASK);
 startActivity(intent);
</code></pre>

blocks|key|633744|text|这就是我所见过的here。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|633745|只需使用它或将其添加到静态类帮助器中，并从项目中的任何位置调用它。|633746|/**

this is what worked for me as seen <a href="http://appglobe.com/restart-an-activity-android" rel="noreferrer">here</a>.

Just use it or add it to a static class helper and just call it from anywher in your project.

<pre><code>/**
Current Activity instance will go through its lifecycle to onDestroy() and a new instance then created after it.
*/
@SuppressLint("NewApi")
 public static final void recreateActivityCompat(final Activity a) {
 if (Build.VERSION.SDK_INT &gt;= Build.VERSION_CODES.HONEYCOMB) {
 a.recreate();
 } else {
 final Intent intent = a.getIntent();
 intent.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
 a.finish();
 a.overridePendingTransition(0, 0);
 a.startActivity(intent);
 a.overridePendingTransition(0, 0);
 }
}

blocks|key|850180|text|我认为对你来说最好的选择是在你的布局中使用SwipeRefreshLayout视图。然后设置RefreshListener+like。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|850181|mySwipeRefreshLayout.setOnRefreshListener(

I think that the best choice for you is using SwipeRefreshLayout View in your layout.
Then set RefreshListener like.

<pre><code>mySwipeRefreshLayout.setOnRefreshListener(
 new SwipeRefreshLayout.OnRefreshListener() {
 @Override
 public void onRefresh() {
 Log.i("Fav ", "onRefresh called from SwipeRefreshLayout");

 // This method performs the actual data-refresh operation.
 // The method calls setRefreshing(false) when it's finished.
 request(); // call what you want to update in this method
 mySwipeRefreshLayout.setRefreshing(false);
 }
 }
 );
</code></pre>

I want to program my android app to refresh its current activity on ButtonClick. I have one button on the top of the activity layout which will do the job. When I click on button the current activity should reload again - just like a device restart.

Thanks

Android refresh current activity

我想对我的安卓应用程序进行编程，以刷新它在ButtonClick上的当前活动。我有一个按钮在顶部的活动布局，这将完成这项工作。当我点击按钮时，当前的活动应该再次重新加载-就像设备重新启动一样。谢谢
