Java 此处理程序可能是静态的，或者蓝牙处理程序可能发生泄漏

您好，我收到处理程序的此警告可能是静态的，或者可能发生泄漏。我曾看过其他帖子，但它并不能帮助我解决问题（警告发生在bluetoothIn的开头，一直持续到结尾

可能重复此操作。因此解决方案如下：

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.bluetooth_datadisplay);


        txtString = (TextView) findViewById(R.id.txtString);
        txtStringLength = (TextView) findViewById(R.id.testView1);
        sensorView0 = (TextView) findViewById(R.id.sensorView0);
        sensorView1 = (TextView) findViewById(R.id.sensorView1);
        sensorView2 = (TextView) findViewById(R.id.sensorView2);
        sensorView3 = (TextView) findViewById(R.id.sensorView3);

     bluetoothIn = new Handler() {
        public void handleMessage(android.os.Message msg) {
            if (msg.what == handlerState) {
                String readMessage = (String) msg.obj;
                recDataString.append(readMessage);
                int endOfLineIndex = recDataString.indexOf("~");
                if (endOfLineIndex > 0) {
                    String dataInPrint = recDataString.substring(0, endOfLineIndex);
                    txtString.setText("Data Received = " + dataInPrint);
                    int dataLength = dataInPrint.length();
                    txtStringLength.setText("String Length = " + String.valueOf(dataLength));

                    if (recDataString.charAt(0) == '#')
                    {
                        String sensor0 = recDataString.substring(1, 5);
                        String sensor1 = recDataString.substring(6, 10);
                        String sensor2 = recDataString.substring(11, 15);
                        String sensor3 = recDataString.substring(16, 20);

                        sensorView0.setText(" Sensor 0 Voltage = " + sensor0 + "V");
                        sensorView1.setText(" Sensor 1 Voltage = " + sensor1 + "V");
                        sensorView2.setText(" Sensor 2 Voltage = " + sensor2 + "V");
                        sensorView3.setText(" Sensor 3 Voltage = " + sensor3 + "V");
                    }
                    recDataString.delete(0, recDataString.length());

                }
            }
        }
    };
  }

@John我试过了。它对我的案例不起作用。@John我试过了。它对我的案例不起作用。Hi@John它不起作用。oncreate块上不允许修改static。我试过了。这是内部类。所以试着将它移出

oncreate

方法。然后像

BluetoothInHandler一样在oncreate中实例化它handler=new BluetoothInHandler（this）

Hi@John。我附上了显示错误的图片。我照你说的做了，但不起作用。顺便说一句，handler（YourActivityName活动）中的这一部分传入的处理程序也用红色下划线。将

mActivity.

放在活动变量或方法之前，例如：

activity.handlerState
