我想知道如何放大已经在ImageView
.
我有这个:
m_imageView.setImageBitmap(imagen);
int newHeight = getWindowManager().getDefaultDisplay().getHeight() / 2;
int orgWidth = m_imageView.getDrawable().getIntrinsicWidth();
int orgHeight = m_imageView.getDrawable().getIntrinsicWidth();
int newWidth = (int) Math.floor((orgWidth * newHeight) / orgHeight);
//Use RelativeLayout.LayoutParams if your parent is a RelativeLayout
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
newWidth, newHeight);
m_imageView.setLayoutParams(params);
//m_imageView.setScaleType(ImageView.ScaleType.FIT_START);
但它什么也没做,图像保持不变。
谢谢您的帮助。
