Get Errs when Using Thread In Android
    I create a simple Project to load all images in drawable
Here is my code

    public void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        list = (ImageView)findViewById(R.id.tung);
        ct = getApplicationContext();
        try
        {
	        IDs = getAllResourceIDs(R.drawable.class);
	        n= IDs.length;
	        dem=0;
	        list.setOnClickListener(new View.OnClickListener()
             {
				public void onClick(View v)
				{
					++dem;
					list.setImageResource(IDs[dem]);
					if(dem==n-1)
						dem=0;
				}
			});
	        
	        Thread x = new Thread(
	        		new Runnable ()
	        		{
	        			public void run()
	        			{
	        				while(true)
	        				{
	        					try
	        					{
		        					++dem;
		        					//Toast.makeText(ct, ""+dem, 20).show();
		        					list.setImageResource(IDs[dem]);
		        					if(dem==n-1)
		        						dem=0;
	        					}
	        					catch(Exception e)
	        					{
	        						//Toast.makeText(ct,e.toString(), 200).show();
	        					}
	        				}
	        			}
	        		}
	        		);
	        x.start();
        }
        catch(Exception e)
        {
        	Toast.makeText(this,e.toString(), 200).show();
        }
    }

anh here is getAllResourceIDs function to get all ids

    private int[] getAllResourceIDs(Class<?> aClass) throws IllegalArgumentException{
        /* Get all Fields from the class passed. */
        Field[] IDFields = aClass.getFields();

        /* int-Array capable of storing all ids. */
        int[] IDs = new int[IDFields.length];

        try {
                /* Loop through all Fields and store id to array. */
                for(int i = 0; i < IDFields.length; i++){
                        /* All fields within the subclasses of R
                         * are Integers, so we need no type-check here. */
                       
                        // pass 'null' because class is static
                        IDs[i] = IDFields[i].getInt(null);
                }
        } catch (Exception e) {
                /* Exception will only occur on bad class submitted. */
                throw new IllegalArgumentException();
        }
        return IDs;

the file main.xml has only a ImageView with id = "tung"
I tried to load all images using a Thead named x
by using code
list.setImageResource(IDs[dem]);
as you can see in my code
but notthing is happen 
Can you explain it for me ! Thank a lot !
