我在使用onclicklistener爲我的傳感器創建按鈕時遇到問題

Question

我正在嘗試爲我的加速計傳感器創建按鈕。該按鈕允許我啓動和停止加速計以獲取所需的值。不過，我想出了一個錯誤 -

The method registerListener(SenesorEventListener, Sensor, int) is not applicable 
for the arguments (new View.OnClickListnere(){}, Sensor, int). 

有誰知道我哪裏出了錯？我已經把按鈕代碼放在protected void onResume（）方法的地方。

import android.app.Activity; 
import android.content.Context; 
import android.hardware.Sensor; 
import android.hardware.SensorEvent; 
import android.hardware.SensorEventListener; 
import android.hardware.SensorManager; 
import android.os.Bundle; 
import android.view.View; 
import android.widget.Button; 
import android.widget.ImageView; 
import android.widget.TextView; 

public class movement extends Activity implements SensorEventListener { 

    private float mLastX, mLastY, mLastZ; 
    private boolean mInitialized; 
    private SensorManager mSensorManager; 
    private Sensor mAccelerometer; 
    private final float NOISE = (float) 2.0; 
    Button startButton, stopButton; 
    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.movement); 
     mInitialized = false; 
     mSensorManager = (SensorManager) getSystemService(Context.SENSOR_SERVICE); 
     mAccelerometer = mSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER); 
     mSensorManager.registerListener(this, mAccelerometer , SensorManager.SENSOR_DELAY_NORMAL); 
    } 

    protected void onResume() { 
     super.onResume(); 

startButton.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 
      mSensorManager.registerListener(this, mAccelerometer, SensorManager.SENSOR_DELAY_NORMAL); 

     } 
    }); 


    } 

    protected void onPause() { 
     super.onPause(); 
     stopButton.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View view) { 
       mSensorManager.unregisterListener(this); 
      } 
     }); 


    } 

    @Override 
    public void onAccuracyChanged(Sensor sensor, int accuracy) { 
     // can be safely ignored for this demo 
    } 

    @Override 
    public void onSensorChanged(SensorEvent event) { 
     TextView tvX= (TextView)findViewById(R.id.x_axis); 
     TextView tvY= (TextView)findViewById(R.id.y_axis); 
     TextView tvZ= (TextView)findViewById(R.id.z_axis); 
     ImageView iv = (ImageView)findViewById(R.id.image); 
     float x = event.values[0]; 
     float y = event.values[1]; 
     float z = event.values[2]; 
     if (!mInitialized) { 
      mLastX = x; 
      mLastY = y; 
      mLastZ = z; 
      tvX.setText("0.0"); 
      tvY.setText("0.0"); 
      tvZ.setText("0.0"); 
      mInitialized = true; 
     } else { 
      float deltaX = Math.abs(mLastX - x); 
      float deltaY = Math.abs(mLastY - y); 
      float deltaZ = Math.abs(mLastZ - z); 
      if (deltaX < NOISE) deltaX = (float)0.0; 
      if (deltaY < NOISE) deltaY = (float)0.0; 
      if (deltaZ < NOISE) deltaZ = (float)0.0; 
      mLastX = x; 
      mLastY = y; 
      mLastZ = z; 
      tvX.setText(Float.toString(deltaX)); 
      tvY.setText(Float.toString(deltaY)); 
      tvZ.setText(Float.toString(deltaZ)); 
      iv.setVisibility(View.VISIBLE); 
      if (deltaX > deltaY) { 
       iv.setImageResource(R.drawable.horizontal); 
      } else if (deltaY > deltaX) { 
       iv.setImageResource(R.drawable.vertical); 
      } else { 
       iv.setVisibility(View.INVISIBLE); 
      } 
     } 
    } 
}

用途：

mSensorManager.registerListener(movement.this, mAccelerometer, SensorManager.SENSOR_DELAY_NORMAL); 

，而不是

mSensorManager.registerListener(this, mAccelerometer, SensorManager.SENSOR_DELAY_NORMAL); 

的setOnClickListener裏面，因爲你是OnClickListener裏面，你需要通過命名來訪問包含類首先
