Question

我使用Tizen的可穿戴式SDK创建了一个表盘，同时我可以使用blueAdapter = tizen.bluetooth.getDefaultAdapter();来检索蓝牙的电源状态bluetoothPowered = blueAdapter.powered;，我宁愿使用蓝牙监听器而不是经常呼叫blueAdapter.powered。

我遇到的问题是，虽然我直接复制并粘贴了示例代码（虽然我确实更改了适配器的名称，请参阅下文）来自Tizen＆＃39; s {{ 1}}网页，我收到以下错误：Bluetooth API。

这是我正在使用的代码：

'undefined' is not a function (evaluating 'blueAdapter.setChangeListener(changeListener)')

不确定是否有帮助，但我使用以下var blueAdapter = tizen.bluetooth.getDefaultAdapter(); var changeListener = { onstatechanged: function(powered) { console.log ("Power state is changed into: " + powered); }, onnamechanged: function( name) { console.log("Name is changed to: " + name); }, onvisibilitychanged: function(visible) { console.log("Visibility is changed into: " + visible); } }; blueAdapter.setChangeListener(changeListener);：

任何帮助都将不胜感激。

虽然现在已经有一段时间了，您是否尝试过更改下面的语法？

function changeListener(handler) {
    handler.onstatechanged = function(powered) {
        console.log ("Power state is changed into: " + powered);
        }
    handler.onnamechanged = function(name) {
          console.log("Name is changed to: " + name);
        }
        handler.onvisibilitychanged = function(visible) {
          console.log("Visibility is changed into: " + visible);
        }
};

这将通过函数替换您的侦听器对象，然后该函数应该在侦听器中声明所需的函数。这只是一个想法，我还没有测试它。
