我想通过编程方式在具有背景图像的相对布局中添加一个 imageView、TextView。我为相对布局指定了高度和宽度,但它不适合指定的宽度和高度。哪里出错了 ploesae help 在此先感谢这是我的代码:
RelativeLayout.LayoutParams lp_topheader = new RelativeLayout.LayoutParams(800,45);
relative_topheader = new RelativeLayout(this);
relative_topheader.setLayoutParams(lp_topheader);
relative_topheader.setId(1);
Resources resources_topheader = getResources();
Drawable drawable_topheader = resources_topheader.getDrawable(R.drawable.headerbar_m);
relative_topheader.setBackgroundDrawable(drawable_topheader);
setContentView(relative_topheader);
RelativeLayout.LayoutParams lp_banner = new RelativeLayout.LayoutParams(385, 206);
relative_banner = new RelativeLayout(this);
relative_banner.setId(2);
relative_banner.setLayoutParams(lp_banner);
lp_banner.setMargins(40, 40, 0, 0);
lp_banner.addRule(RelativeLayout.BELOW,1);
ImageView iv = new ImageView(this);
iv.setScaleType(ScaleType.FIT_XY);
iv.setLayoutParams(lp_banner);
Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.banner_image);
iv.setImageBitmap(bitmap);
setContentView(iv, lp_banner);
