android - 如何以编程方式启动 Google Now 语音搜索？

Question

我想在用户按下按钮时启动 Google Now 语音搜索。但是，我在文档中找不到开始搜索的 Intent 。

有人知道如何开始Google Now 语音搜索的 Activity 吗？

Answer 1

语音输入的调用 Activity :

/* Call Activity for Voice Input */
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);

intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, "en-US");

try {
    startActivityForResult(intent, 1);
} catch (ActivityNotFoundException a) {
    Toast.makeText(context, "Oops! Your device doesn't support Speech to Text",Toast.LENGTH_SHORT).show();
}

从字符串中获取输入:

(我已用于在搜索 View 中设置文本并搜索该值)

/* When Mic activity close */
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    switch (requestCode) {
    case 1: {
        if (resultCode == Activity.RESULT_OK && null != data) {
            String yourResult = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS).get(0);
        }
        break;
    }
    }
}
