mListView = (ListView) findViewById(R.id.lv);
et = (EditText) findViewById(R.id.et);
adapter = BluetoothAdapter.getDefaultAdapter();
BlueToothHandler.getInstance().setContext(this);
init();
}
private void init()
{
initListView();
// 判断是否支持蓝牙功能
if (adapter == null)
{
Toast.makeText(this, "该手机不支持蓝牙功能", Toast.LENGTH_LONG).show();
return;
}
