You can write CSS according to the width and height of the design manuscript, then judge different size screen by JS, modify Like the design draft is 640 * 1136We can write pages at 640 width or 320 width.Then The default width can be set to the width of the page you are writing.
1. Layout optimizationFirst remove the unused controls and hierarchies from the layout, and then selectively use the lower-performing viewgroup, such as Relativelayout and LinearLayout in the layout, then we use LinearLayout, Because the Relativelayout function is more complex, its layout takesGrace Oh CPU actually.Another way to optimize layout is to use The layout in Xmlns:hyhotel= "Http://schemas.android.com/apk/res/com.hysmarthotel.movie" >Add view yourself as neededNote the ID, then this ID
