我目前正在研究Ionic 2應用程序項目,該項目允許用戶錄製自己的聲音,停止錄製並播放聲音。根據離子本機,我可以看到他們提供了2個插件,即MediaPlugin和MediaCapture。我嘗試過使用MediaPlugin,但在開始記錄時遇到了問題,請停下並播放它。 有沒有人經歷過使用這個插件?我已經瀏覽了離子文檔和其他一些博客,但仍然無法完成。我對此很新,非常感謝你的努力。我很欣賞你的想法。如何在Ionic 2上錄製音頻和播放?
問候,
這是我從模擬器了,同時開始記錄日誌:

這裏是我的home.ts代碼:
import {Component} from '@angular/core';
import {NavController, Platform, Page, Events} from 'ionic-angular';
import {MediaPlugin} from 'ionic-native';
@Component({
templateUrl: 'build/pages/home/home.html'
})
export class HomePage {
private _platform: Platform;
private _fileRecord: MediaPlugin;
private _pathFile: string;
private _nameFile: string;
constructor(private navCtrl: NavController, platform: Platform) {
this._platform = platform;
}
public startRecord(): void {
this._pathFile = this.getPathFileRecordAudio();
this._fileRecord = new MediaPlugin(this._pathFile);
this._fileRecord.startRecord();
}
public stopRecord(): void {
this._fileRecord.stopRecord();
}
private startPlay(): void {
this._fileRecord = new MediaPlugin(this._pathFile);
this._fileRecord.play();
}
private getPathFileRecordAudio(): string {
let path: string = (this._platform.is('ios') ? '../Library/NoCloud/': '../Documents/');
return path + this._nameFile + '-' + '.wav';
}
}
