How to add images dynamically to an ImageView?

Try setting up a few int arrays to store your drawable and widget IDs. It's faster than using reflection to find them by name. Something like this should do the trick.

A0, R.id. A1, R.id. B0, R.id.

B1, R.id. C0, R.id. C1 //... }; int images = { R.drawable.

A0, R.drawable. A1, R.drawable. B0, R.drawable.

B1, R.drawable. C0, R.drawable. C1 //... }; Random random = new Random(System.

CurrentTimeMillis()); for(int v : imageViews) { ImageView iv = (ImageView)findViewById(v); iv. SetImageResource(imagesrandom. NextInt(images.

Length - 1)); } You may want to add some special handling if you want to ensure that all the ImageViews get unique images, but that should work as is.

Just realized I had sTiles. Length in my code; should have been images.length. :) Changed it.

An solution is read with reflection the values from R. Drawable and load it as Bitmap by getting the value of the field in R. It's something like: public static void example() throws IllegalArgumentException, IllegalAccessException{ Class clazz = R.drawable.

Class; for(Field field : clazz. GetDeclaredFields()){ Bitmap bmp = BitmapFactory. DecodeResource(getResources(), (Integer) field.

Get(null)); //bmp is your image } }.

You'll have to make some sort of container(Linear Or Relative layout possibly) and add the images to the view. Example: RelativeLayout cbrl = new RelativeLayout(this); RelativeLayout. LayoutParams cbp = new RelativeLayout.

LayoutParams( LayoutParams. WRAP_CONTENT, LayoutParams. WRAP_CONTENT); cbVal.

SetLayoutParams(cbp); for(i=0; I XX); cbrl. AddView(iv); }.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
