调用方法时出错setRequestedOrientation（）

Question

public void onSensorChanged(SensorEvent e) { 
    if (e.sensor.getType()==Sensor.TYPE_ACCELEROMETER) { 

     if(e.values[0] >= 8) 
      setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); 
     else 
      setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); 
    } 
} 

当该方法被称为setRequestedOrientation（） - 错误。创建layout-land并在那里放置main.xml文件的副本。

Answer 1

尝试这种::

SensorManager sensorMgr; 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 
    sensorMgr = (SensorManager) getSystemService(SENSOR_SERVICE); 
    sensorMgr.registerListener(this, 
      SensorManager.SENSOR_ACCELEROMETER, 
      SensorManager.SENSOR_DELAY_GAME); 
} 


public void onSensorChanged(int sensor, float[] values){ 
    if (sensor==Sensor.TYPE_ACCELEROMETER) { 
     if(values[0] >= 8) 
      setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); 
     else 
      setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); 
    } 
}
