android - 如何以编程方式激活 Lenovo Mirage Solo Daydream 上的屏幕录像机？

Question

目前，Lenovo Mirage Solo daydream 设备可以按音量键和菜单来激活屏幕录制。有没有办法以编程方式触发相同的功能？

我查看了文档，找不到任何相关内容。

Answer 1

KeyEvent volDown = new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_VOLUME_DOWN);
Activity.dispatchKeyEvent(volDown);
KeyEvent menuDown = new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent. KEYCODE_MENU);
Activity.dispatchKeyEvent(menuDown);

KeyEvent volUp = new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_VOLUME_DOWN);
Activity.dispatchKeyEvent(volUp);
KeyEvent menuUp = new KeyEvent(KeyEvent.ACTION_UP, KeyEvent. KEYCODE_MENU);
Activity.dispatchKeyEvent(menuUp);

我没有对此进行测试，因为我没有这部手机，但这是我最好的猜测。前四行按下音量键和菜单键 (ACTION_DOWN)，后四行释放它们 (ACTION_UP)。希望它对你有用:)我假设这适用于菜单和音量减小，但如果它是音量增大，则只需将 KEYCODE_VOLUME_DOWN 换成 KEYCODE_VOLUME_UP
