shown).If you have deleted fragment actions in the executed transaction and have not called addtobackstack (), the deleted fragment will be destroyed when the transaction commits. Conversely, those fragment will not be destroyed, but in a stopped state. When the user returns, they are restored.Secret skill: For fragment transactions, you can apply animations. Calling Settransition () before commit () is OK. --General Silver I won't tell him.However, after a commit () is called, the transaction

to Y = 2, the answer is no, because Y is a synchronized variable, prevents reordering, X does not cross the memory barrier after the y=2, sob = x is also not reordered to the front of a = y, because y is a variable that is synchronized, and the memory barrier also does not allow the actions behind the barrier to cross over to the frontSo as long as Y =2 writes occur before a = y read operation, then the last x = 1 must precede b=x, so B = 1Resources:Happens-before of the Vulgar solutionTalk abo

WebView How to interact with HTMLMany times webview need to interact with HTML, either through Java code to control the page activity, or through JS trigger Java code, WebView provides the medium mechanism.First, let's look at the HTML code we need to interact with:Simple HTML code, three lines of text, a button. Document.body.innerHTML is to get the contents of the body node in the HTML.Then we load it in and turn on JS:Webview.loadurl ("file:///android_asset/MyHtml.html"); Webview.getsettings
