根据垂直搜索栏调整图像大小？

Question

我正在尝试通过移动垂直搜寻栏来测量用户身高。问题是，当我尝试调整图像大小时，某些屏幕上的图像看起来比搜索栏缩略图大，或者比缩略图小。我怎么解决这个问题。我写的代码：

 verticalSeekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
            @Override
            public void onProgressChanged(SeekBar seekBar, int progress, boolean b) {
                int measure = (int) ((((float) progress * point.x) / 250) - (progress * 0.5)) - 250;

                if (progress > 140) {
                    if (point.x - measure < personImage.getHeight()) {
                        params.height = point.x - personImage.getHeight();
                    } else {
                        params.height = measure;
                    }


                    // Set LayoutParams
                    personImage.setLayoutParams(params);
                }
            }

            @Override
            public void onStartTrackingTouch(SeekBar seekBar) {

            }

            @Override
            public void onStopTrackingTouch(SeekBar seekBar) {

            }
        });

这是我要存档的结果：

如果您的搜寻栏最大值！= 100，那么很可能会解决您的问题：

LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
verticalSeekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
    @Override
    public void onProgressChanged(SeekBar seekBar, int progress, boolean b) {

        params.height = (int) (verticalSeekBar.getHeight() * (float) progress / YOUR_MAX_VALUE) + (int)((YOUR_MAX_VALUE - progress) / 2);
        personImage.setLayoutParams(params);
    }

    @Override
    public void onStartTrackingTouch(SeekBar seekBar) {

    }

    @Override
    public void onStopTrackingTouch(SeekBar seekBar) {

    }
});
