android 打造变化多端的SeekBar（垂直和水平）

2021-01-26
SeekBar相信用的人不是很多，一般都是用水平SeekBar就可以了。但是之前项目中考虑使用垂直的SeekBar，就要继承重写SeekBar才能用。而垂直SeekBar在百度搜了一下，关于这方面文章还是很少，有一些还是不全面。我又去了github找了一下，找到了一个垂直的效果以及源码，我就写了一个滚动SeekBar翻页listview的数据效果。所以这篇博客中源码下载中，有三个项目源码，干货多多。

1、先看一下水平SeekBar
这种是用系统SeekBar，是水平的。我在滚动SeekBar上面加了页码提示。滚动页码时候也可以翻页listview的数据。先看效果。
看着上面效果还是很不错吧，觉得很赞。接下来看看原理。
其实这个原理很简单，这个滚动SeekBar以及listview管理都是一系列的序号，就是多少项数据的索引吧。用一个list记住每一页的表头第一项的索引值，因为每一页数据都是固定。就比如每一页数据是30，那么第一页第一项索引就是0，第二页是30，第三页是60.。。。以此类推，还有根据你滑动进度条，获得那一页数据，再根据这一页表头索引加上30就是这一页的数据。所以管理都是序号或者说索引。所以所以最后获取数据是这样的mArrayList.get(mPageItemsIndex.get(position).intValue())。而这个就是每一页数据索引值mPageItemsIndex.get(position).intValue()。好了说了那么多，看代码吧。
先看这个public class LevelPageSeekBar extends SeekBar
package com.org.view;import com.org.pageseekbar.R;import android.content.Context;import android.util.AttributeSet;import android.widget.SeekBar;import android.widget.TextView;//自定义页码进度条public class LevelPageSeekBar extends SeekBar {private QuickAction mSeekBarTipsQuickAction;private int mPageCount = 0;private boolean mIsTouch = false;private TextView mTipsTitle;private OnSeekBarPageChangeListener mBarPageChangeListener;public LevelPageSeekBar(Context context, AttributeSet attrs) {super(context, attrs);mSeekBarTipsQuickAction = new QuickAction(context, QuickAction.HORIZONTAL);ActionItem tipsItem = new ActionItem(0, context.getResources().getString(R.string.Move), null);tipsItem.setIcon(null);mSeekBarTipsQuickAction.addActionItem(tipsItem);mTipsTitle = (TextView)mSeekBarTipsQuickAction.GetActionItemsGroup().getChildAt(0).findViewById(R.id.tv_title);//设置系统进度条的监听setOnSeekBarChangeListener(mSeekBarChangeListener);//最大页码是10000setMax(10000);}//进度条改变的接口public interface OnSeekBarPageChangeListener {public abstract void setSeekBarScrolling(TextView tips, int page);public abstract void setSeekBarPageChanged(int page);}//注册接口public void setSeekBarPageChangeListener(OnSeekBarPageChangeListener listener) {mBarPageChangeListener = listener;}//设置进度条页数public void setPagesCount(int count) {mPageCount = count;}//设置不显示弹出第几页提示public void setHideSeekPopWindow() {mSeekBarTipsQuickAction.dismiss();}private int getProgressIsPageIndex(int progress, int max) {if (mPageCount < 2) {if (progress == 0) return 0;else return 1;}if (progress == 0) return 0;// 获取每一块的进度值int progressSizeEveryPage = getMax()/(mPageCount-1);for (int i = 1; i < mPageCount; i++) {if (progress <= (i)*progressSizeEveryPage && progress > ((i-1)*progressSizeEveryPage)) {if (progress > (2*i-1)*progressSizeEveryPage/2 ) return i;else return i-1;}}return mPageCount-1;}//外面调用上下按键翻页，需要同时滚动进度条效果public void setProgressSpecialPage(int pageIndex, int count) {if (count <= 1) {setProgress(0);return;}mPageCount = count;if (pageIndex < 0 || pageIndex >= mPageCount) return;int progressSizeEveryPage = getMax()/(mPageCount-1);setProgress( progressSizeEveryPage*pageIndex);}//弹出当前显示第几页的提示private void showSeekPopWindow() {if (mSeekBarTipsQuickAction == null) return;// 获取每一刻度的宽度float thumb_x = ((float)this.getWidth() - 44)/(float)this.getMax();// 获取控件的屏幕位置int[] location = new int[2];this.getLocationOnScreen(location);int x = (int) ((float)thumb_x*(float)getProgress()) + 22;if (mBarPageChangeListener != null) mBarPageChangeListener.setSeekBarScrolling(mTipsTitle, getProgressIsPageIndex(getProgress(), getMax()));mSeekBarTipsQuickAction.show(this, (int)(x + location[0]), location[1]);}//系统进度条的监听方法private OnSeekBarChangeListener mSeekBarChangeListener = new OnSeekBarChangeListener() {@Overridepublic void onStopTrackingTouch(SeekBar arg0) {mIsTouch = false;setHideSeekPopWindow();}@Overridepublic void onStartTrackingTouch(SeekBar arg0) {mIsTouch = true;}@Overridepublic void onProgressChanged(SeekBar arg0, int arg1, boolean arg2) {if (mIsTouch) showSeekPopWindow();if (mBarPageChangeListener != null) mBarPageChangeListener.setSeekBarPageChanged( getProgressIsPageIndex(getProgress(), getMax()));}};}再看怎么调用或者说使用。看MainActivity

2、现在看看我在github上找的垂直SeekBar效果
从上而下那个调整画布是这样的，还有一些计算。。。看源码也是继承SeekBar
protected void onSizeChanged(int w, int h, int oldw, int oldh) { super.onSizeChanged(h, w, oldh, oldw); } @Override protected synchronized void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { super.onMeasure(heightMeasureSpec, widthMeasureSpec); setMeasuredDimension(getMeasuredHeight(), getMeasuredWidth()); } //初始值从上往下 protected void onDraw(Canvas c) { c.rotate(90); c.translate(0, -getWidth()); super.onDraw(c); } @Override public boolean onTouchEvent(MotionEvent event) { if (!isEnabled()) { return false; } switch (event.getAction()) { case MotionEvent.ACTION_DOWN: case MotionEvent.ACTION_MOVE: case MotionEvent.ACTION_UP: int i=0; i=getMax() - (int) (getMax() * event.getY() / getHeight()); setProgress(100-i); Log.i("Progress",getProgress()+""); onSizeChanged(getWidth(), getHeight(), 0, 0); break; case MotionEvent.ACTION_CANCEL: break; } return true; } protected void onSizeChanged(int w, int h, int oldw, int oldh) { super.onSizeChanged(h, w, oldh, oldw); } @Override protected synchronized void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { super.onMeasure(heightMeasureSpec, widthMeasureSpec); setMeasuredDimension(getMeasuredHeight(), getMeasuredWidth()); } //初始值从下往上 protected void onDraw(Canvas c) { c.rotate(-90); c.translate(-getHeight(),0); super.onDraw(c); } @Override public boolean onTouchEvent(MotionEvent event) { if (!isEnabled()) { return false; } switch (event.getAction()) { case MotionEvent.ACTION_DOWN: case MotionEvent.ACTION_MOVE: case MotionEvent.ACTION_UP: int i=0; i=getMax() - (int) (getMax() * event.getY() / getHeight()); setProgress(i); Log.i("Progress",getProgress()+""); onSizeChanged(getWidth(), getHeight(), 0, 0); break; case MotionEvent.ACTION_CANCEL: break; } return true; }3、看看我写的垂直SeekBar效果
还是一样，先看效果。
也是对这个listview的数据管理的。就是没有弹出页码的提示，因为弹出感觉不好看，就删了。
看源码：VerticalPageSeekBar extends SeekBar
package com.vertical.view;import android.content.Context;import android.graphics.Canvas;import android.util.AttributeSet;import android.view.MotionEvent;import android.widget.SeekBar;//自定义页码进度条public class VerticalPageSeekBar extends SeekBar {private int mPageCount = 0;private OnSeekBarPageChangeListener mBarPageChangeListener; public VerticalPageSeekBar(Context context) { super(context); } public VerticalPageSeekBar(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); } public VerticalPageSeekBar(Context context, AttributeSet attrs) {super(context, attrs);//设置系统进度条的监听super.setOnSeekBarChangeListener(new OnSeekBarChangeListener() {@Overridepublic void onStopTrackingTouch(SeekBar arg0) {}@Overridepublic void onStartTrackingTouch(SeekBar arg0) {}@Overridepublic void onProgressChanged(SeekBar seekBar, int progress,boolean fromUser) {if (mBarPageChangeListener != null) //接口回调mBarPageChangeListener.setSeekBarPageChanged( getProgressIsPageIndex(progress, getMax()));}});setMax(1000);}//进度条改变的接口public interface OnSeekBarPageChangeListener {public abstract void setSeekBarPageChanged(int page);}//注册接口public void setSeekBarPageChangeListener(OnSeekBarPageChangeListener listener) {mBarPageChangeListener = listener;}//Thumb的变化情况 protected void onSizeChanged(int w, int h, int oldw, int oldh) { super.onSizeChanged(h, w, oldh, oldw); } //测量宽度也需要旋转 @Override protected synchronized void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { super.onMeasure(heightMeasureSpec, widthMeasureSpec); setMeasuredDimension(getMeasuredHeight(), getMeasuredWidth()); } //画布旋转90 protected void onDraw(Canvas c) { c.rotate(-90); c.translate(-getHeight(),0); super.onDraw(c); } @Override public boolean onTouchEvent(MotionEvent event) { if (!isEnabled()) { return false; } switch (event.getAction()) { case MotionEvent.ACTION_DOWN: case MotionEvent.ACTION_MOVE: case MotionEvent.ACTION_UP: int i=0; //设置y值为进度条的值 i=getMax() - (int) (getMax() * event.getY() / getHeight()); setProgress(i); onSizeChanged(getWidth(), getHeight(), 0, 0); break; case MotionEvent.ACTION_CANCEL: break; } return true; }//设置进度条页数public void setPagesCount(int count) {mPageCount = count;}//分页的进度条的段值private int getProgressIsPageIndex(int progress, int max) {if (mPageCount < 2) {if (progress == 0) return 0;else return 1;}if (progress == 0) return 0;// 获取每一块的进度值int progressSizeEveryPage = getMax()/(mPageCount-1);for (int i = 1; i < mPageCount; i++) {if (progress <= (i)*progressSizeEveryPage && progress > ((i-1)*progressSizeEveryPage)) {if (progress > (2*i-1)*progressSizeEveryPage/2 ) return i;else return i-1;}}return mPageCount-1;}//外面调用上下按键翻页，需要同时滚动进度条效果public void setProgressSpecialPage(int pageIndex, int count) {if (count <= 1) {setProgress(0);return;}mPageCount = count;if (pageIndex < 0 || pageIndex >= mPageCount) return;int progressSizeEveryPage = getMax()/(mPageCount-1);setProgress( progressSizeEveryPage*pageIndex);//设置进度条按钮跟着移动 onSizeChanged(getWidth(), getHeight(), 0, 0);}}还有怎么使用MainActivity
