[英]How to connect an app to a Bluetooth headset
我正在嘗試將我的應用程序連接到藍牙耳機,但我收到了mProfileListener
錯誤。 我不知道在哪里以及如何聲明mProfileListener
。 這是我的代碼:
// Get the default adapter
BluetoothAdapter mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
// Establish connection to the proxy.
mBluetoothAdapter.getProfileProxy(this, mProfileListener, BluetoothProfile.HEADSET);
private BluetoothProfile.ServiceListener mProfileListener = new BluetoothProfile.ServiceListener() {
public void onServiceConnected(int profile, BluetoothProfile proxy) {
if (profile == BluetoothProfile.HEADSET) {
mBluetoothHeadset = (BluetoothHeadset) proxy;
Log.d("TAGP","BLuetooth Headset: "+mBluetoothHeadset);
Log.d("TAGP ","Proxy: "+proxy);
}
}
public void onServiceDisconnected(int profile) {
if (profile == BluetoothProfile.HEADSET) {
mBluetoothHeadset = null;
}
}
};
// ... call functions on mBluetoothHeadset
// Close proxy connection after use.
mBluetoothAdapter.closeProfileProxy(mBluetoothHeadset);
}
您可以在類范圍中聲明mProfileListener實例,如下所示:
private BluetoothProfile.ServiceListener mProfileListener;
然后在你的“連接”藍牙堆棧方法中,你可以像你的代碼一樣初始化這個mProfileListener實例。
