Problems solved by technology

A complex Android application usually consists of a large number of Fragments. Different Fragments display different interfaces to implement different operations. When a large number of Fragments are loaded into memory at the same time, the memory space occupied by those Fragments that are not currently displayed is wasted. Generally, at the same time Only 1 to 3 Fragments will be displayed, so if Fragments are not properly managed, a lot of memory will be wasted
In another case, loading Fragment into memory involves disk I / O operations, which are slow and affect user experience

Abstract

The present invention provides a method and terminal for loading a Fragment, wherein the method includes: generating a tree structure of a Fragment node; determining the position information of the Fragment node on the tree structure; setting the loading status information of the Fragment node ; Load the Fragment on the corresponding child node according to the loading status information of the Fragment node; unload the Fragment on the parent node or brother node corresponding to the child node. Through the above method, the present invention can reduce the occupation of memory, release excess memory in time, improve the I / O efficiency of terminal equipment, and also make it possible for complex programs to run on low-end equipment.

Description

technical field [0001] The invention relates to the technical field of Android, in particular to a method and a terminal for loading a Fragment. Background technique [0002] Fragment is a component in Android, which is used to display interface content, and can accept operations such as user clicks and drags to interact with users. A complex Android application usually consists of a large number of Fragments. Different Fragments display different interfaces to implement different operations. When a large number of Fragments are loaded into memory at the same time, the memory space occupied by those Fragments that are not currently displayed is wasted. Generally, at the same time Only 1 to 3 Fragments will be displayed, so if Fragments are not properly managed, a lot of memory will be wasted. In another case, loading Fragment into memory involves disk I / O operations, which are slow and affect user experience. Contents of the invention [0003] The technical problem to be...
