mui调用图像裁剪android：

var IMAGE_UNSPECIFIED = "image/*"; //相册显示的文件类型

var PHOTOZOOM = 2; // 获取完图片返回key

var PHOTOLAT = 1; // 剪裁完毕后返回key

var main = plus.android.runtimeMainActivity(); //h5+获取应用主Activity实例对象

var Intent = plus.android.importClass("android.content.Intent");

//导入java类intent对象  以下importClass都是使用安卓原生类

var MediaStore = plus.android.importClass("android.provider.MediaStore");

var File = plus.android.importClass("java.io.File");

var Uri = plus.android.importClass("android.net.Uri");

var intent = new Intent(Intent.ACTION_PICK, null);

intent.setDataAndType(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, IMAGE_UNSPECIFIED);

intent.putExtra("scale", true);

intent.putExtra("scaleUpIfNeeded", true);

var outPutPath = plus.io.convertLocalFileSystemURL("_www/head.jpg");

main.startActivityForResult(intent, PHOTOZOOM);

// uploadImgPath

main.onActivityResult = (requestCode,resultCode,data)=>{

// main.onActivityResult = function(requestCode, resultCode, data) {

    if (PHOTOZOOM == requestCode) {

        var file = new File(outPutPath);

        // 输出目录uri

        var outPutUri = Uri.fromFile(file);

        if (data == undefined) {

            return false;

        }

        plus.android.importClass(data);

        var uri = data.getData();

        var cropIntent = new Intent("com.android.camera.action.CROP"); //裁剪

        cropIntent.setDataAndType(uri, IMAGE_UNSPECIFIED);

        // 截图完毕后 输出目录

        cropIntent.putExtra(MediaStore.EXTRA_OUTPUT, outPutUri);

        cropIntent.putExtra("crop", "true");

        //aspectX aspectY 是宽高的比例

        cropIntent.putExtra("aspectX", 1);

        cropIntent.putExtra("aspectY", 1);

        // outputX outputY 是裁剪图片宽高

        cropIntent.putExtra("outputX", 70);

        cropIntent.putExtra("outputY", 70);

        cropIntent.putExtra("return-data", true);

        main.startActivityForResult(cropIntent, PHOTOLAT);

    } else if (requestCode == PHOTOLAT) {

        if (data == undefined) {

            return false;

        }

        var a = new File(outPutPath);

        if (!a.exists()) {

            console.log(outPutPath);

            mui.toast('裁剪错误');

            return false;

        }

        var base64Path =

        this.uploadImgPath = outPutPath;

        console.log(outPutPath);

        alert(outPutPath);

        // img.src = outPutPath;

    };

};
