的Android如何在手機周圍

Question

開啓這是我的手機是否被轉頭或不

private SensorManager sensorManager; 
    private int orientationLim = 165; 

@Override 
    public void onSensorChanged(SensorEvent event) { 
     if (event.sensor.getType() == Sensor.TYPE_ORIENTATION) { 

      // If shake to stop is enabled 
      boolean turnAroundToStop = Utils.getBooleanFromProperties(this, Properties.SP_CB_TURN_AROUND_TO_STOP); 

      if (turnAroundToStop) { 
       float value = Math.abs(event.values[1]); 
       if (value > orientationLim && !stopped) { 
        // Down 
        stopped = true; 
       } else { 
        // Up 
        stopped = false; 
       } 
      } 
     } 
    } 

，但問題是，stopped變量設置爲true，即使手機沒有完全轉過身來，但檢測代碼檢測只是一點點。

我該如何修改此代碼，該代碼僅在手機中繼轉身時纔會執行。

Answer 1

float pitch = values[2]; 
if (pitch <= 45 && pitch >= -45) { 
    // mostly vertical 
} else if (pitch < -45) { 
    // mostly right side up 
} else if (pitch > 45) { 
    // mostly left side up 
}
