android中怎么让一个活动不占满整个屏幕

Answer 1

直接调用这方法，会返回一张和屏幕大小相同的图片

public static Bitmap FitTheScreenSizeImage(Bitmap m,int ScreenWidth, int ScreenHeight)
{
float width = (float)ScreenWidth/m.getWidth();
float height = (float)ScreenHeight/m.getHeight();
Matrix matrix = new Matrix();
matrix.postScale(width,height);
return Bitmap.createBitmap(m, 0, 0, m.getWidth(), m.getHeight(), matrix, true);
}
