J2me中的画布上的文本框

Question

I am going to make application on j2me using canvas. I want to take textbox or textfield on my canvas.

Answer 1

You can draw a basic textbox and display a string , and when it receives focus, you can switch the view to that particular textbox ,something like this

textBox = new TextBox(....);
Midlet.display.setCurrent(textBox);

This would create your data entry more robust and save you from the pain of implementing various keyboard issues yourselves

Answer 2

These items are only available for adding to Form s . Canvas is a class for handling lower-level events.

You have to implement your own textbox, and that isn't easy.
Basic textbox would be a rectangle ( drawRect ) with text ( drawString ) inside of it.
