Experience solves the problem that fragment is still visible after replace

Most of the questions asked on the Internet refer to the replacement of fragment and the previous replacement is still shown there. I personally use the Android 2.3 +support development package, and a similar problem occurs on the 2.3 system. After searching the internet, it seems that no solution has been found. Then I groped myself. Finally found that the replacement Java code for fragment basically nothing, the Internet is correct, such as:

2. Fragmentmanager Fragmentmanager = Getsupportfragmentmanager ();
4. Fragmenttransaction transaction = Fragmentmanager.begintransaction ();
6. Orderfragment orderfragment = new Orderfragment ();
8. Bundle args = new bundle ();
10. Args.putint ("card_id", LoginHelper.currentCard.getId ());
12. Args.putboolean ("Create_order", true);
14. Orderfragment.setarguments (args);
20. Transaction.replace (R.id.layout_shopping1, orderfragment);
22. Transaction.addtobackstack (NULL);
24. Transaction.commit ();

Copy Code

But most people don't realize the importance of pasting XML layout files:
The correct approach is that you must use Framelayout as a layout container for fragment to be replaced
For example:

1. <?xml version= "1.0" encoding= "Utf-8"?>
2. <framelayout xmlns:android= "Http://schemas.android.com/apk/res/android"
3. Android:id= "@+id/layout_shopping1"
4. Android:layout_width= "Match_parent"
5. android:layout_height= "Wrap_content"
6. android:background= "@color/black" >
8. </FrameLayout>

Copy Code

Can not use such as linear layout linearlayout, etc., otherwise there will be visible problems.
Give a little experience and expect to help developers with similar problems.
