For that, I\'m using a

Answer 1

Change the width of Relativelayout to wrap_content.

Try using this method to add the view.

void addView (View child, ViewGroup.LayoutParams params)

EDIT:
Remove android:orientation="horizontal" from the HorizontalScrollView

Answer 2

Try this code.

ImageView imageView = new ImageView(this);
    imageView.setScaleType(ImageView.ScaleType.FIT_CENTER);
    imageView.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,
                LayoutParams.WRAP_CONTENT));
    imageView.setBackgroundColor(Color.blue);


parent.addView(v,params);

Answer 3

you add the view into the relativelayout not into the horizontalscrollview using parent

try with the horizontalscrollview object as you can done with the relativelayout

Answer 4

HorizontalScrollView scrollView = (HorizontalScrollView) findViewById(R.id.scrollView1);

        LinearLayout topLinearLayout = new LinearLayout(this);
       // topLinearLayout.setLayoutParams(android.widget.LinearLayout.LayoutParams.FILL_PARENT,android.widget.LinearLayout.LayoutParams.FILL_PARENT);
        topLinearLayout.setOrientation(LinearLayout.HORIZONTAL); 

        for (int i = 0; i < 15; i++){



            final ImageView imageView = new ImageView (this);

            imageView.setTag(i);

            imageView.setImageResource(R.drawable.ic_launcher);

            topLinearLayout.addView(imageView);

            imageView.setOnClickListener(new OnClickListener()
            {

                @Override
                public void onClick(View v)
                {
                    // TODO Auto-generated method stub
                    Log.e("Tag",""+imageView.getTag());
                }
            });


        }

        scrollView.addView(topLinearLayout);
