1.创建uts项目
2.创建uts插件cf-takepic
3.在index.uts中编写原生安卓代码，首先定义一个函数方法，在页面中看是否可引用成功
uts函数代码
/**
* 拍照函数
*/
export const takepic=function():void{
console.log("11111111")
}index.vue代码
<template>
<view class="content">
<view class="text-area">
<button @click="take">拍照</button>
</view>
</view>
</template>
<script>
//引入uts插件
import {takepic} from "../../uni_modules/cf-takepic"
export default {
data() {
return {
}
},
onLoad() {
},
methods: {
take(){
//调用uts插件函数
takepic()
}
}
}
</script>
<style>
.content {
display: flex;
flex-direction: column;
align-items: center;
justify-content: center;
}
</style>
4.运行到手机或模拟器，成功打印111111即可视为调用uts插件成功
5.修改uts插件takepic函数，原生android唤起手机相机功能
uts代码
/**
* 引用 Android 系统库，示例如下：
* import { Context } from "android.content.Context";
* [可选实现，按需引入]
*/
/* 引入 interface.uts 文件中定义的变量 */
import { MyApiOptions, MyApiResult, MyApi, MyApiSync } from '../interface.uts';
/* 引入 unierror.uts 文件中定义的变量 */
import { MyApiFailImpl } from '../unierror';
import Intent from "android.content.Intent";
import MediaStore from "android.provider.MediaStore";
/**
* 更多插件开发的信息详见：https://uniapp.dcloud.net.cn/plugin/uts-plugin.html
*/
/**
* 拍照函数
*/
export const takepic=function():void{
console.log("11111111")
let takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
UTSAndroid.getUniActivity()!.startActivityForResult(takePictureIntent, 999);
UTSAndroid.onAppActivityResult((requestCode : Int, resultCode : Int, data ?: Intent) => {
if (requestCode == 999) {
console.log("拍照回调");
} else {
// 别的代码发起的请求，不要处理
}
});
}拍照打印日志
6.再次修改uts代码，获取图片路径
uts代码
/**
* 引用 Android 系统库，示例如下：
* import { Context } from "android.content.Context";
* [可选实现，按需引入]
*/
/* 引入 interface.uts 文件中定义的变量 */
import { MyApiOptions, MyApiResult, MyApi, MyApiSync } from '../interface.uts';
/* 引入 unierror.uts 文件中定义的变量 */
import { MyApiFailImpl } from '../unierror';
import Intent from "android.content.Intent";
import MediaStore from "android.provider.MediaStore";
import File from "java.io.File";
import SimpleDateFormat from "java.text.SimpleDateFormat";
import Environment from "android.os.Environment";
import Uri from "android.net.Uri";
import FileProvider from "androidx.core.content.FileProvider";
import ActivityCompat from "androidx.core.app.ActivityCompat";
import Manifest from "android.Manifest";
import PackageManager from "android.content.pm.PackageManager";
/**
* 更多插件开发的信息详见：https://uniapp.dcloud.net.cn/plugin/uts-plugin.html
*/
/**
* 拍照函数
*/
export const takepic = function () : void {
// 检查相关权限是否已经具备
if (ActivityCompat.checkSelfPermission(UTSAndroid.getUniActivity()!, Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED) {
// 不具备权限，申请权限，并且告知用户监听失败
ActivityCompat.requestPermissions(UTSAndroid.getUniActivity()!, arrayOf(Manifest.permission.CAMERA), 1002)
return;
}
console.log("11111111")
let takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
let photoFile = createImageFile();
console.log(photoFile)
let photoUri = FileProvider.getUriForFile(UTSAndroid.getAppContext()!,
"com.cf.take",
photoFile as File);
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoUri as Uri);
UTSAndroid.getUniActivity()!.startActivityForResult(takePictureIntent, 999);
UTSAndroid.onAppActivityResult((requestCode : Int, resultCode : Int, data ?: Intent) => {
if (requestCode == 999) {
console.log("拍照回调");
console.log(photoUri.toString());
} else {
// 别的代码发起的请求，不要处理
}
});
}
export const createImageFile = function () : File {
let timeStamp = "123456789";
let imageFileName = "JPEG_" + timeStamp + "_";
let storageDir = UTSAndroid.getAppContext()!.getExternalFilesDir(Environment.DIRECTORY_PICTURES);
console.log(storageDir,"storageDir")
let image = File.createTempFile(
imageFileName, /* prefix */
".jpg", /* suffix */
storageDir /* directory */
);
console.log(image,"image")
return image as File;
}日志
