Good android development the great god,

Is self-study Android development, the language is Java, want to try on a page to fill in the content, and then in the main page, is displayed in the MainActivity,
I used to do data transmission, the bundle on the content of the input page,
At the time of with intent, I wrote a
Intent Intent=new Intent (new_experienceActivity. MainAcitivity. Class);
So, want to convey content from the new activity to MainAcitivy, but procedure on running collapse,

I can realize B page input, according to the C page but not achieve the page input B content in the MainActivity, according to the corresponding page program also didn't start to collapse,

Don't know how to change, should seek a great god advice ~

Intent Intent=new Intent (the current page as an example, the target page. The class).

CodePudding user response:

Intent Intent=new Intent (Context, the target page. The class).
What do you want to jump to this is to tell system activity, and then through the intent object put various types of data, the new activity by getIntent accept it

If you want, MainActivity to receive data should be how to do intent and bundle

Intent and data format is

 
Intent Intent=new Intent (A, biggest lass); 
Intent. PutExtra (" XXX ", "* *"); 
StartActivity (intent);
