android studio intent to pass data between activities

It supports all types of primitive data types and also it helps to share a data class object too. Using this method the intent is passed as a parameter while calling this we can share the data to the different activities. Finally the code starts the new intent.In Android application development, the intent can be called using the startActivity() method. The code then creates a string variable and passes it to the intent, giving it the same name as the variable specified in the activity 'onCreate' method within the 'getString' method call. In another activity class within your application, launch the activity using the following syntax: Intent newIntent = new Intent(this, DataActivity.class) String someText = 'hello' newIntent.putExtra(this.getPackageName() + '.dataString', someText) this.startActivity(newIntent) This code creates a new intent, specifying the class name of the new activity.

The reference for the item also includes the package name, to avoid any confusion if the variable names are used by more than one application.Ĭreate an intent to launch your new activity. This demonstrates retrieving a string item with 'dataString' as its reference. Inside the conditional block, add code to retrieve the passed data items using the following syntax: String passedText = extras.getString(this.getPackageName() + '.dataString'). Add the following outline for the method which will execute when an instance of the class is created: public void onCreate(Bundle savedInstanceState) Inside this conditional block your code can retrieve the data.

Implement the 'onCreate' method for your new class.
