ImageView-如何以编程方式膨胀或添加？

Question

I am programmatically adding ImageView without success. Is there any simple way to add ImageView into Activity programmatically?

Thx

Edit:

I have tried this and it is not working.

                for(Bitmap b: photoField){
                try{
                    Log.d("BIT", "Bitmapa "+b);
                    if(b!=null){
                        ImageView imv=new ImageView(PoiDisplay.this);
                        imv.setImageBitmap(b);
                    }
                }catch (NullPointerException e) {
                    e.printStackTrace();
                }
            }

Answer 1

get the layout id in which u want to place the images then

Relative or Linear or any other layout..

RelativeLayout urLayoutId=(RelativeLayout)finViewById(R.id.RelativeLayoutIdInXml);

    for(Bitmap bitmap: photoField){
                    try{

                        if(bitmap!=null){
                            ImageView img=new ImageView(PoiDisplay.this);
                            img.setImageBitmap(bitmap);
                            urLayoutId.addView(img);
                        }
                    }catch (NullPointerException e) {
                        e.printStackTrace();
                    }
            }

Answer 2

Use this code

ImageView i=new ImageView(this);
i.setImageResource(R.drawable.ic_launcher);

Answer 3

you are only creating it not adding it. To add your view on layout. First create or fetch layout.

LinearLayout lp = (LinearLayout) findViewByid(R.id.linear_layout_name)

            for(Bitmap b: photoField){
            try{
                Log.d("BIT", "Bitmapa "+b);
                if(b!=null){
                    ImageView imv=new ImageView(PoiDisplay.this);
                    imv.setImageBitmap(b);
                    lp.addview(imv)
                }
            }catch (NullPointerException e) {
                e.printStackTrace();
            }
