Use intent to pass data between activity in Android

simple use of intent transfer data in android:

1. Pass data using intent:

first put the data that needs to be passed into the intent

Intent Intent = new Intent (mainactivity.this,otheractivity.class);

Intent.putextra ("name", " passing Data using intent");

StartActivity (Intent);

then receive the data in the target activity:

Intent intent=getintent ();

Intent.getstringextra ("name")// Get Data

2. use intent to pass static variables:

a static variable is set in the target activity, the data is stored in a static variable when the target activity is started, and then read directly in the target activity.

Intent Intent = new Intent (Mainactivity.this,

Other2activity.class);

Other2activity.data = " pass static variable with intent";

StartActivity (Intent);

3. passing global variables using intent

New Class MYAPP Inherits application, specifying the Name property of the application node in the Androidmanifest.xml file as MYAPP (android:name= ". MyApp ")

public class MyApp extends application {

Publicstring data;

Publicstring GetData () {return data; }

Public Voidsetdata (String data) {This.data =data; }

@Override public void OnCreate () {

Super.oncreate ();

SetData ("Hello World");

} }

}

writes data to the global variable when the target activity is started :

Intent Intent = new Intent (mainactivity.this,other3activity.class);

MyApp MyApp = (MyApp) getapplication ();

Myapp.setdata (" use intent to pass global Variables ");

StartActivity (Intent);

To receive data in the target activity:

MyApp myapp= (MyApp) getapplication ();

Myapp.getdata ();

4. using the Clipboard to pass data

Write the data that you want to pass to the Clipboard:

Intent Intent =new Intent (Mainactivity.this,

Clipboardactivity.class);

Clipboardmanagerclipboardmanager= (Clipboardmanager) Getsystemservice (MainActivity.this.CLIPBOARD_SERVICE);

Clipboardmanager.settext (" using the Clipboard to transmit data ");

StartActivity (Intent);

and then in the target Activity value in:

Clipboardmanager clipboardmanager= (Clipboardmanager) Getsystemservice (Clipboardactivity.clipboard_service);

Clipboardmanager.gettext ();

above is some simple activity data transfer. Besides, I'm at the end of the development app will use some app test the online automated test tool: www.ineice.com
