从浮点数中获取值0我只是将值设置为

Question

我有两个方法，1个注册值，它看起来像这样：

    public void setCordinates(float x, float y, float x2, float y2){
    String str = new String();
    str = "DETAILS. X Value: "+x+". Y Value: "+y;
    Log.d("DETAILZZZ", str);
    str = "DETAILS2222 X Value: "+x2+". Y Value: "+y2;
    Log.d("DETAILZZZ2",str);

    this.x1=(x);
    this.x2=(x2);
    this.y1=(y);
    this.y2=(y2);
    str = "DETAILS. X Value: "+this.x1+". Y Value: "+this.y1;
    Log.d("DETAILZZZ", str);
    str = "DETAILS2222 X Value: "+this.x2+". Y Value: "+this.y2;
    Log.d("DETAILZZZ2",str);
}

在这个参数中，我目前传递X值：180.0。 Y值：140.0和X值：520.0。 Y值：450.0

当我在上面的方法中打印出来时，logcat给了我正确的值：这是logcat：

D/DETAILZZZ2﹕ DETAILS2222 X Value: 520.0. Y Value: 450.0
D/DETAILZZZ﹕ DETAILS. X Value: 180.0. Y Value: 140.0

但是在我需要使用这个值的其他方法中，logcat将这些变量显示为零，这里是代码。

protected void onDraw(Canvas canvas) {
    // TODO Auto-generated method stub
    String str = new String();
    super.onDraw(canvas);
    mFinalbitmap = BitmapFactory.decodeResource(getResources(), R.drawable.planr);
    mFinalbitmap = Bitmap.createScaledBitmap(mFinalbitmap, getWidth(), getHeight(), true);
    paint.setStyle(Paint.Style.STROKE);
    str = "DETAILS----------Width: "+getWidth()+". Heigth: "+getHeight()+". X Value: "+this.x1+". Y Value: "+this.y1;
    Log.d("DETAILZZZ", str);
    str = "DETAILS2222----------Width: "+getWidth()+". Heigth: "+getHeight()+". X Value: "+x2+". Y Value: "+y2;
    Log.d("DETAILZZZ2", str);
    this.x1=((getWidth()/599f)*x1);
    this.x2=((getWidth()/599f)*x2);
    this.y1=((getHeight()/740f)*y1);
    this.y2=((getHeight()/740f)*y2);

    canvas.drawBitmap(mFinalbitmap, 0, 0, null);
    canvas.drawCircle(x1, y1, 30, paint);
    canvas.drawCircle(x2, y2, 30, paint);
}

Logcat给出了这个：

DETAILS----------Width: 1080. Heigth: 1533. X Value: 0.0. Y Value: 0.0
D/DETAILZZZ2﹕ DETAILS2222----------Width: 1080. Heigth: 1533. X Value: 0.0.          Y Value: 0.0
