Question

I put an ArrayList object into a bundle of my activity. Now in the next view I want to fill the content of these list elements into my view. How can I write something into my Edittext field in the onCreate method?

EditText comment;


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_comment_picture);

    if (savedInstanceState != null){

        ArrayList<String> selectedPics = (ArrayList<String>) savedInstanceState.get("pics");                        
    }       
}

Thank you

Found your EditText you can with method findViewById(), like this

comment = (EditText) findViewById(R.id.ID_THAT_YOU_SET_IN_XML_FILE_FOR_THAT_WIDGET);

If you want add all items of selectedPics in one string, you can use thatcode:

final StringBuilder builder = new StringBuilder();
for (String item: selectedPics) {
    builder.append(item);
}
comment.setText(builder.toString());

Or, if you need set items in different lines and your EditText is multiline, use that code:

final StringBuilder builder = new StringBuilder();
for (String item: selectedPics) {
    builder.append(item).append("\n");
}
comment.setText(builder.toString());
