Question

我的代码曾经用于2.2，我能够获得陀螺仪数据，但在更新到2.3后，它不再起作用了。我还试过一个Galaxy播放器来确保它不是我手机的硬件问题。它也不适用于那个。有什么建议？这是代码：

    package my.acc;

    import java.io.File;
    import java.io.FileNotFoundException;
    import java.io.FileOutputStream;
    import java.io.PrintWriter;

    import android.app.Activity;

    import android.hardware.Sensor;
    import android.hardware.SensorManager;
    import android.os.Bundle;
    import android.view.View;
    import android.view.View.OnClickListener;
    import android.widget.ArrayAdapter;
    import android.widget.EditText;
    import android.widget.Spinner;
    import android.widget.ToggleButton;

    public class myact extends Activity {

        private SensorManager mSensorManager;
        Sensor myAcc, myAcc2, myAcc3, myAcc4;
        MySensorListener listener, listener2,listener3, listener4;
        EditText mEdit;



        /** Called when the activity is first created. */
        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.main);

            final Spinner spinner = (Spinner) findViewById(R.id.spinner);
            ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(
                    this, R.array.activity_array, android.R.layout.simple_spinner_item);
            adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
            spinner.setAdapter(adapter);


            // Set up the accelerometer reading
            mSensorManager = (SensorManager)getSystemService(SENSOR_SERVICE);
            myAcc = mSensorManager.getDefaultSensor(Sensor.TYPE_LINEAR_ACCELERATION);
            myAcc2 = mSensorManager.getDefaultSensor(Sensor.TYPE_GYROSCOPE);
            myAcc3 = mSensorManager.getDefaultSensor(Sensor.TYPE_ORIENTATION);
            myAcc4 = mSensorManager.getDefaultSensor(Sensor.TYPE_GRAVITY);

            final ToggleButton togglebutton = (ToggleButton) findViewById(R.id.togglebutton);
            mEdit   = (EditText)findViewById(R.id.entry);

            togglebutton.setOnClickListener(new OnClickListener() {
                PrintWriter mCurrentFile = null;
                PrintWriter mCurrentFile2 = null;
                PrintWriter mCurrentFile3 = null;
                PrintWriter mCurrentFile4 = null;


                public void onClick(View v) {
                    // Perform action on clicks
                    if (togglebutton.isChecked()) {

                        String strname = spinner.getSelectedItem().toString();
                        if (strname.equals("Select Activity")){
                            strname = mEdit.getText().toString();
                        }

                        File outputFile = new File(nameStr);
                        File outputFile2 = new File(nameStr2);
                        File outputFile3 = new File(nameStr3);
                        File outputFile4 = new File(nameStr4);

                        try {
                            mCurrentFile = new PrintWriter(new FileOutputStream(outputFile));
                            mCurrentFile2 = new PrintWriter(new FileOutputStream(outputFile2));
                            mCurrentFile3 = new PrintWriter(new FileOutputStream(outputFile3));
                            mCurrentFile4 = new PrintWriter(new FileOutputStream(outputFile4));

                        } catch (FileNotFoundException e) {
                            // TODO Auto-generated catch block
                            e.printStackTrace();

                        mSensorManager.registerListener(listener4 = new MySensorListener(mCurrentFile4), myAcc4 , SensorManager.SENSOR_DELAY_UI);

                        //mSensorManager.registerListener(listener, myAcc2 , SensorManager.SENSOR_DELAY_FASTEST);

                    } else {


                        mSensorManager.unregisterListener(listener, myAcc);
                        mSensorManager.unregisterListener(listener2, myAcc2);

                    }
                }
            });
        }
    }

package my.acc;

import java.io.PrintWriter;

public class MySensorListener implements SensorEventListener {

    String comma = new String(",");
  private PrintWriter mCurrentFile;

    public MySensorListener( PrintWriter mCurrentFile){
      //Creating a file to print the data into

      this.mCurrentFile = mCurrentFile;

    }


    public void onAccuracyChanged(Sensor sensor, int accuracy) {
            // TODO Auto-generated method stub

    }



    public void onSensorChanged(SensorEvent event) {

        StringBuffer buff = new StringBuffer();

        buff.append(String.valueOf(event.sensor.getName()));     
        buff.append(comma);


        buff.append(String.valueOf(event.timestamp));


        buff.append(comma);

          buff.append(String.valueOf(event.values[0]));
          buff.append(comma);
          buff.append(String.valueOf(event.values[1]));
          buff.append(comma);
          buff.append(String.valueOf(event.values[2]));

        mCurrentFile.println(buff.toString());
        mCurrentFile.flush();


    }


}

我甚至报道谷歌这里的一个错误就是他们的反应：

这些不是Google设备，因此您必须与三星交谈

Answer 1

我不确定这是否有帮助，但它似乎与您的问题有关：陀螺仪无法闪烁rom。您可以查看（Galaxy S2 - Gyro & Compass not working）并尝试运行建议的测试。

Answer 2

似乎只是一个三星问题。向Google提出问题没有帮助;他们把我转回三星。

更新到2.3.5后，GYROSCOPE不起作用
