三、实战练习
截图另外做文档答题。文档要求,文件名:某某研究日志日期。文件内容,题目和答题,截图代码和文字等综合展示。
1.练习题一
以下是基于DevEco Studio蛟龙腾飞北向应用开发工程师已经实现的布局、功能、代码及路径,请安装要求一模一样的流程和效果,在自己的DevEco Studio实现。这里我们可以自行选择自己想开发的设备和模板,这里我们以Phone为例,开发模板选择空特性java的开发模板,点击next进行下一步。
开发的设备有七种:
- Phone
- Tablet
- Car
- Tv
- Wearable
- Lite wearable
- smart vision
Phone设备中有很多种不同的模板,主要是java和js进行开发以及不同的模板样式,不同样式之间布局不一样,不同的布局所展示的效果代码已经写入其中,只需要加入想加入的元素即可。
选择好了之后点击next进行下一步。
这里是创建项目的一些项目配置,配置完成点击Finish完成创建。
完成创建后,我们进入了主界面,这里需要等待一小会,因为一些配置东西在进行下载配置。

在slice文件的类中添加点击事件进行跳转:
- Button button = (Button) findComponentById(ResourceTable.Id_jltfbutton);
- button.setClickedListener(new Component.ClickedListener() {
- @Override
- public void onClick(Component component) {
- present(new JltfAbilitySlice(),new Intent());

在第一个页面js文件中加入跳转的代码
- jltfclick() {
- router.replace({

- });
- }
还得在配置文件中配置相关下一个页面的位置
config.json找到图中js的位置
- "js": [
- {
- "pages": [
- "pages/index/index",
- "pages/jltfindex/jltfindex"
- ],
- "name": "default"
- }
- ]
加入"pages/jltfindex/jltfindex"下一个页面位置即可

Jltfindex.js
- export default {

- }
然后进行页面跳转的配置
在一个页面index.js中进行配置
- jltfclick() {
- router.replace({
- uri:'pages/jltfindex/jltfindex'
- });
- }
这样了还不能跳转,“wearable”和“litewearable”有不同,在litewearable中这样就可以进行跳转了,但是在wearable中还需要在config.json中进行配置,添加跳转的页面的地址
- "js": [
- {
- "pages": [
- "pages/index/index",
- "pages/jltfindex/jltfindex"
- ],
- "name": "default",
- "window": {
- "designWidth": 454,
- "autoDesignWidth": false
- }
- }
- ]
找到图中位置添加
- "pages/jltfindex/jltfindex"
就可以了
