AndroidStudio里使用google TTS引擎播放声音

1.首先下载google TTS安装包，在你的安卓手机上进行安装。

2.将手机的默认文字播放引擎设置为google TTS。以红米手机为例：设置-更多设置-语言与输入法-文字转语音输出

3.在AndroidManifest.xml中申请权限

XML 复制代码

    <queries>
        <intent>
            <action android:name="android.intent.action.TTS_SERVICE" />
        </intent>
    </queries>

（这段代码可放在application标签前面）

4.在代码中播放声音（包括了兼容性验证、音量设定）
