Question

我自定义Android默认搜索栏以垂直方式显示并使用片段获取用户的一些反馈。

首次发布后，它显示正常。但是，一旦我提交了我的第一反馈，我就会使用包含我自定义的Vertical Seek Bar的片段重新启动活动。

那时，Vertical Seekbar中的拇指将变为“0”，但进度不会变为“0”并显示一些进展。 :(

下面我正在添加我的垂直搜索条形码，如果我错过任何东西请建议我。

public class VerticalSeekBar extends SeekBar {
    private int mLastProgress = 0;

    private OnSeekBarChangeListener mOnChangeListener;

    public VerticalSeekBar(Context context) {
    super(context);
    }

    public VerticalSeekBar(Context context, AttributeSet attrs) {
    super(context, attrs);
    }

    public synchronized int getMaximum() {
    return getMax();
    }

    @Override
    protected void onDraw(Canvas c) {
    c.rotate(-90);
    c.translate(-getHeight(), 0);
    super.onDraw(c);
    }

    @Override
    protected synchronized void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
    super.onMeasure(heightMeasureSpec, widthMeasureSpec);
    setMeasuredDimension(getMeasuredHeight(), getMeasuredWidth());
    }

    @Override
    protected void onSizeChanged(int w, int h, int oldw, int oldh) {
    super.onSizeChanged(h, w, oldh, oldw);
    }

    @Override
    public boolean onTouchEvent(MotionEvent event) {
    if (!isEnabled()) {
        return false;
    }

    switch (event.getAction()) {
        case MotionEvent.ACTION_DOWN:
        if (mOnChangeListener != null) {
            mOnChangeListener.onStartTrackingTouch(this);
        }
        setPressed(true);
        setSelected(true);
        break;
        case MotionEvent.ACTION_MOVE:
        super.onTouchEvent(event);
        int progress = getMax() - (int) (getMax() * event.getY() / getHeight());

        // Ensure progress stays within boundaries
        if (progress < 0) {
            progress = 0;
        }
        if (progress > getMax()) {
            progress = getMax();
        }
        setProgress(progress); // Draw progress
        if (progress != mLastProgress) {
            // Only enact listener if the progress has actually changed
            mLastProgress = progress;
            if (mOnChangeListener != null) {
            mOnChangeListener.onProgressChanged(this, progress, true);
            }
        }

        onSizeChanged(getWidth(), getHeight(), 0, 0);
        setPressed(true);
        setSelected(true);
        break;
        case MotionEvent.ACTION_UP:
        if (mOnChangeListener != null) {
            mOnChangeListener.onStopTrackingTouch(this);
        }
        setPressed(false);
        setSelected(false);
        break;
        case MotionEvent.ACTION_CANCEL:
        super.onTouchEvent(event);
        setPressed(false);
        setSelected(false);
        break;
    }
    return true;
    }

    public synchronized void setMaximum(int maximum) {
    setMax(maximum);
    }

    @Override
    public void setOnSeekBarChangeListener(OnSeekBarChangeListener onChangeListener) {
    this.mOnChangeListener = onChangeListener;
    }

    public synchronized void setProgressAndThumb(int progress) {
    setProgress(progress);
    onSizeChanged(getWidth(), getHeight(), 0, 0);
    if (progress != mLastProgress) {
        mLastProgress = progress;
        if (mOnChangeListener != null) {
        mOnChangeListener.onProgressChanged(this, progress, true);
        }
    }
    }

    public synchronized void setMyProgress(int progress) {
    setProgress(progress);
    }
}

最后我得到了解决问题的方法。在创建垂直seekBar的.xml中我使用了 android：progressDrawable =“@ drawable / seek”但是在seek.xml中我忘了将标题声明为

1) Clear a cookie value

2) Set 307 header value and

3) Adding Location header with redirect url (say request B) value.

item android：id =“@ android：id / progress”。

活动/片段重新启动后，搜索栏进度未更新
