Android: passing text from an app to another one
In my Android project, I launch an application from another one, by using an intent, in this way:
Intent intent = new Intent(Intent.ACTION_MAIN);
intent.setComponent(new ComponentName("edu.dhbw.andar.sample","edu.dhbw.andar.sample.CustomActivity"));
startActivity(intent);
And it works: the second application starts without problems. Now, I wish to pass a text string from the first application to the seco开发者_如何学编程nd one. Is there a way to do that?
Thanks
Put an extra String in the intent (using intent#putExtra()) and read it in the new application:
In the first application:
intent.putExtra("IdentifierForYourString", theString);
In the second:
getIntent().getStringExtra("IdentifierForYourString");
Put the string in the intent
Intent intent = new Intent(Intent.ACTION_MAIN);
intent.setComponent(new ComponentName("edu.dhbw.andar.sample","edu.dhbw.andar.sample.CustomActivity"));
intent.putExtra("Key", myString);
startActivity(intent);
Then in your new activity you do:
getParent().getActivity().getIntent().getExtras().getString("Key");
to get shipped string.
You can use Bundles to send extra information from one activity to another, i.e.:
Intent intent = new Intent(Intent.ACTION_MAIN); intent.setComponent(new
ComponentName("edu.dhbw.andar.sample","edu.dhbw.andar.sample.CustomActivity"));
intent.putExtra("myparameter", "myvalue"); startActivity(intent);
In the targeted activity you can retrieve the extra information like:
protected void onCreate(Bundle savedInstance) {
super.onCreate(savedInstance);
Bundle extras = getIntent().getExtras();
Log.d("LOG", extras.getString("myparameter");
}
Hope this helps.
