我希望通过一个安卓应用来检查设备的蓝牙是否已开启。 我使用了.isEnabled方法。但出现了错误。通过注释掉一些代码,我发现报错就在.isEnabled这个方法里。请问您能否帮我解决这个问题?
final BluetoothAdapter bluetooth = BluetoothAdapter.getDefaultAdapter();
submitButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String status = "Bluetooth";
if(bluetooth != null) {
if (bluetooth.isEnabled()) {
String mydeviceaddress = bluetooth.getAddress();
String mydevicename = bluetooth.getName();
status = ("Address "+ mydeviceaddress + " Name" + mydevicename);
Toast.makeText(getApplicationContext(), "" + status + "", Toast.LENGTH_LONG).show();
} else {
status = ("Bluetooth not enabled");
Toast.makeText(getApplicationContext(), "" + status + "", Toast.LENGTH_LONG).show();
}
} else {
Toast.makeText(getApplicationContext(), "" + status + "", Toast.LENGTH_LONG).show();
}
}
}
