android - ACTION_VOICE_COMMAND 什么都不做

Question

我正在使用此代码 fragment 在 Android 上激活语音命令。

  Intent newIntent = new Intent(Intent.ACTION_VOICE_COMMAND);
    newIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    getApplicationContext().sendBroadcast(newIntent);

它没有做任何事情，甚至在我的日志猫中也没有错误:

    disable_snd_device: snd_device(2: speaker)

当我在 ADB 中运行它时，它会启动谷歌助手:

adb shell am start -a android.intent.action.VOICE_COMMAND

这很奇怪，从技术上讲这是一回事。是否有我遗漏的权限？

Answer 1

From Docs

Activity Action: Start Voice Command.

所以要调出语音命令助手 Activity ，使用startActivityas

getApplicationContext().startActivity(newIntent);

代替

getApplicationContext().sendBroadcast(newIntent);

喜欢

Intent newIntent = new Intent(Intent.ACTION_VOICE_COMMAND);
newIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
getApplicationContext().startActivity(newIntent);
//                      ^^^^^^^^^^^^

is there a way for the UI not to come up and cover my UI? or at least for google assistant to go away after it listened and acted on my voice command?

您可以使用 Google Assistant Service sdk这是android quick start guide
