如何在j2me中使一些文本框彼此相邻

Question

i'm working on a j2me project with java wireless toolkit and i need to make 4 textbox next to each other. i used these for:

private TextField emailTxt;
private TextField passwordTxt;
private TextField nameTxt;
private TextField mobileTxt;
private TextField urlTxt; 

public UserRegistrationMIDlet() {
    emailTxt = new TextField("pelak:\n", "", 2, TextField.EMAILADDR);
    passwordTxt = new TextField("", "", 1, TextField.PASSWORD);
    nameTxt = new TextField("", "", 3, TextField.ANY);
    mobileTxt = new TextField("", "", 2, TextField.PHONENUMBER);
    urlTxt = new TextField("address:", "", 100, TextField.URL);

}

but j2me textboxes and textfields, every one fill a line and become under each other. as i searched for i understood the Textbox has no set location method but isn't there any other way to make them just next to each other? fn: some one said that it's possible with changing the margins?! how?!

Answer 1

I'm assuming you are adding these TextField to a Form , so, according to documentation :

Layout policy in Form is organized around rows. Rows are typically related to the width of the screen, respective of margins, scroll bars, and such. All rows in a particular Form will have the same width. Rows do not vary in width based on the Items contained within the Form, although they may all change width in certain circumstances, such as when a scroll bar needs to be added or removed. Forms generally do not scroll horizontally.

But you play with setLayout . For example:

emailTxt.setLayout(Item.LAYOUT_2 | Item.LAYOUT_SHRINK);
passwordTxt.setLayout(Item.LAYOUT_2 | Item.LAYOUT_SHRINK);
nameTxt.setLayout(Item.LAYOUT_2 | Item.LAYOUT_SHRINK);
mobileTxt.setLayout(Item.LAYOUT_2 | Item.LAYOUT_SHRINK);
urlTxt.setLayout(Item.LAYOUT_2 | Item.LAYOUT_SHRINK);

As a last resort you can build your own input field extending from CustomItem and have all your fields merged into one.
