我正在开发Android上的远程控制应用程序。
这是我隐藏的描述符。我能够发送以下关键事件：降低音量/提高音量，dpad中心/提高音量/降低音量/向左/右键。
private static final byte[] REPORT_MAP_REMOTE_WORKING = {
USAGE_PAGE, 0x0c, // Usage Page (Consumer Devices)

// VOLUME DOWN - 0 byte 1 bit - 0x02

USAGE, (byte) 0x45,
REPORT_COUNT, COUNT_01,
INPUT, 0x06, // Input (Data, Variable, Relative)
// VOLUME MUTE - 0 byte 7 bit - 0x80
USAGE, (byte) 0xe2,
REPORT_COUNT, COUNT_01,
INPUT, 0x06, // Input (Data, Variable, Relative)
END_COLLECTION, // End Collection
};
我如何编辑此描述符以能够在任何遥控器上发送带有相应颜色按钮（红色，绿色，黄色，蓝色）的事件？
答案 0 :(得分：0)
红色/绿色/蓝色/黄色按钮也是“消费者”页面上的用法。 试试这个：
