我在imageview
内有一个scrollview
。但是,旋转时,横向图像高度大于屏幕。这会导致imageview
消失。这不是内存问题,因为我删除了图像本身的设置,只是设置了背景颜色。如果我设置较小的高度,则imageview不会消失。当高度大于屏幕时,有没有办法防止图像视图消失?
答案 0 :(得分:0)
我认为你需要使用Display
类,这是它的完整示例
//get Display info
Display d = getWindowManager().getDefaultDisplay();
//get screen h/w
int w = d.getWidth();
int h = d.getHeight();
ImageView img = ( ImageView ) findViewById(R.id.myimage);
//i want to set imageview full screen for example
img.getLayoutParams().height = h;
img.getLayoutParams().width = w;
// and this to set h or w by percentage let say 15% of screen
img.getLayoutParams().height = (int)(h/100)*15;
img.getLayoutParams().width = (int)(w/100)*15;
//or if height large than screen resize it
if ( img.getHeight() > h)
{
img.getLayoutParams().height = (int)(h/100)*95;
}
希望这个帮助
