Abstract

The invention provides an implementation method and system for Android native and QT mixed development. The method comprises the steps that 1, the size and position relation of a QT interface and an Android native interface displayed in the same Activity are determined in advance; 2, when the Activity of the application is created, a layout file is set in a user-defined mode based on the size and the position relation, and the overall layout Layout is divided into a sub-layout Layout to which a QT interface belongs and other sub-layouts Layout; 3, in the QT initialization process, a Surface is created based on the Android system environment, and the created Surface is attached to a sub-layout Layout to which a QT interface belongs; 4, at least one QT interface is developed through the QT framework, and the at least one QT interface is displayed on the Surface; and at least one Activity is developed through an Android native development framework, and the Surface of the QT to a sub-layout Layout is associated to which a QT interface corresponding to the at least one Activity belongs. According to the method, the QT interface and the Android native interface can be displayed on the same Activity, and picture fusion is realized.

Description

technical field [0001] The invention relates to the technical field of application program development, in particular to a method and a system for realizing mixed development of native Android and QT. Background technique [0002] With the development of automobiles, QT is more and more widely used in the field of vehicle systems. It is mainly used in the development of automotive instrumentation, infotainment systems, and rear entertainment systems. QT has certain advantages in developing 3D applications compared to native Android development. advantages; Android native development has wider applicability, and many third-party libraries only provide libraries for Android native development; if the two are used in combination in application development, and each completes different functions, it can not only improve development efficiency, And combining QT's advantages in 3D can achieve more cool effects. [0003] The existing QT itself is cross-platform and can be transpla...
