如何以编程方式设置ImageButton的宽度,高度和边距？

Answer 1

您好朋友,您可以通过以下代码设置

btnPlayVideo.getLayoutParams().height = XX;
btnPlayVideo.getLayoutParams().width = XX;

或者看到这个图片按钮调整大小

Answer 2

//ImageView Setup
ImageView imageView = new ImageView(this);

//setting height and width of imageview
LayoutParams params = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);

//setting margins around imageimageview
params.setMargins(10, 10, 10, 10); //left, top, right, bottom

//adding attributes to the imageview
imageView.setLayoutParams(params);
