Bitmap Width, Height without memory allocation:

BitmapFactory.Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = true;
BitmapFactory.decodeResource(getResources(), R.id.myimage, options);
// now opts.outWidth and opts.outHeight are the dimension of the
// bitmap, even though Bitmap is null
int imageHeight = options.outHeight;
int imageWidth = options.outWidth;
String imageType = options.outMimeType;

Example source code for Android Developers

// clickable TextView
public TextView createTextView(String sText, Context con){
 TextView b = null;
 try {
  b = new TextView (con);
  b.setTextSize(15.0f);
  b.setTextColor(Color.rgb( 0, 0, 200));
  b.setOnClickListener(this);
  b.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,
  LayoutParams.WRAP_CONTENT));
  b.setText(sText);
  //tr.addView(b, 60,30);
  } catch (Exception e) {
  e.printStackTrace();
 return b;
 }
return b;
}
