我要开发混合应用程序 列出蓝牙装置 扫描和连接 共享文件等等
所以我想将 BlueoothAdapter mAdapter mAdapter 值添加到额外值中, 并将其传递到活动结果中。 如 enableIntent.putExtra (", mAdapter); , 并将其用于 activityResult , 由 getExtra (...) (...) <.) 。 是否有办法这样做??
if (!mBluetoothAdapter.isEnabled()) {
Intent enableIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
((Activity)context).startActivityForResult(enableIntent, RequestCodes.BLUETOOTH_ENABLE_CODE);
}
