J2ME Draw String

     

In the previous examples, we learned about drawing different graphics on the screen. Here in this example, we are going to show the string in J2ME. For that we have created a a class called GraphicsCanvas class that extends to the Canvas class to draw the string.

Given methods are used to set the actual layout of the text on the screen.

  • setColor()
  • fillRect()
  • drawString()
  • getHeight()
  • getWidth()

  g.TOP will show the string on Top and g.LEFT set it in the left alignment. The drawString() method is used to show the string on the screen.

 

The Application is as follows:

Simple Graphic

Source Code of SimpleGraphics.java

 

import javax.microedition.midlet.*;
import javax.microedition.lcdui.*;

public class SimpleGraphics extends MIDlet{
  private Display display;

  public SimpleGraphics(){}

  public void startApp(){
  Canvas canvas = new GraphicsCanvas();
  display = Display.getDisplay(this);
  display.setCurrent(canvas);
  }

  public void pauseApp(){}

  public void destroyApp(boolean unconditional){}
}
class GraphicsCanvas extends Canvas{
  public void paint(Graphics g){
  int x = 0, y = 0;
  g.setColor(255162117);
  g.fillRect(00, getWidth(), getHeight());
  g.setColor(00255);
  g.drawString("Sandeep Kumar Suman", x, y, g.TOP | g.LEFT);
  }
}

EXCEPTION???

Nice tutorial, simple and clean. But I have a frigging problem with the drawString function. I can fill a rect, set color, set font, but when I wanna drawString, it just throws a IllegalArgumentException. Do you have any idea what the problem is??? Thanks
