Answer 1

Использование библиотеки по этой ссылке: This link и положить в свой проект,

Создайте SeekBar Как это класс:

package com.tokaracamara.android.verticalslidevar; 
import android.content.Context; 
import android.graphics.Bitmap; 
import android.graphics.Bitmap.Config; 
import android.graphics.BitmapFactory; 
import android.graphics.Canvas; 
import android.graphics.Color; 
import android.graphics.Paint; 
import android.graphics.Point; 
import android.graphics.Rect; 
import android.graphics.Typeface; 
import android.graphics.drawable.BitmapDrawable; 
import android.graphics.drawable.Drawable; 
import android.util.AttributeSet; 
import android.view.MotionEvent; 
public class DemoSeek extends AbsVerticalSeekBar { 
    public interface OnSeekBarChangeListener { 
     void onProgressChanged(DemoSeek seekBar, int progress, boolean fromUser); 

    void onStartTrackingTouch(DemoSeek seekBar); 

    void onStopTrackingTouch(DemoSeek seekBar); 
} 

private OnSeekBarChangeListener mOnSeekBarChangeListener; 

private Drawable progressDrawable; 
private Rect barBounds, labelTextRect; 
private Bitmap labelBackground; 
private Point labelPos; 
private Paint labelTextPaint, labelBackgroundPaint; 

int viewWidth, barHeight, labelOffset; 
// private int thumbX; 
float progressPosX; 
private String expression; 

public DemoSeek(Context context) { 
    super(context); 
    // Log.i("Seekbar", "DemoSeek"); 
    progressDrawable = getProgressDrawable(); 

    // labelBackground = BitmapFactory.decodeResource(getResources(), 
    // R.drawable.thumb_marker); 

    labelBackground = drawableToBitmap(mThumb); 

    labelTextPaint = new Paint(); 
    labelTextPaint.setColor(Color.WHITE); 
    labelTextPaint.setTypeface(Typeface.DEFAULT_BOLD); 
    labelTextPaint.setAntiAlias(true); 
    labelTextPaint.setDither(true); 
    labelTextPaint.setTextSize(13f); 

    labelBackgroundPaint = new Paint(); 

    barBounds = new Rect(); 
    labelTextRect = new Rect(); 

    labelPos = new Point(); 

} 

public Bitmap drawableToBitmap(Drawable drawable) { 
    if (drawable instanceof BitmapDrawable) { 
     return ((BitmapDrawable) drawable).getBitmap(); 
    } 

    Bitmap bitmap = Bitmap.createBitmap(drawable.getIntrinsicWidth(), 
      drawable.getIntrinsicHeight(), Config.ARGB_8888); 
    Canvas canvas = new Canvas(bitmap); 
    drawable.setBounds(0, 0, canvas.getWidth(), canvas.getHeight()); 
    drawable.draw(canvas); 

    return bitmap; 
} 

@Override 
void onProgressRefresh(float scale, boolean fromUser) { 
    super.onProgressRefresh(scale, fromUser); 

    if (mOnSeekBarChangeListener != null) { 
     mOnSeekBarChangeListener.onProgressChanged(this, getProgress(), 
       fromUser); 
    } 
} 

public DemoSeek(Context context, AttributeSet attrs) { 
    super(context, attrs); 

    progressDrawable = getProgressDrawable(); 

    labelBackground = BitmapFactory.decodeResource(getResources(), 
      R.drawable.thumb_with_arrow); 

    labelTextPaint = new Paint(); 
    labelTextPaint.setColor(Color.WHITE); 
    labelTextPaint.setTypeface(Typeface.DEFAULT_BOLD); 
    labelTextPaint.setAntiAlias(true); 
    labelTextPaint.setDither(true); 
    labelTextPaint.setTextSize(15f); 

    labelBackgroundPaint = new Paint(); 

    barBounds = new Rect(); 
    labelTextRect = new Rect(); 

    labelPos = new Point(); 
} 

@Override 
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { 
    super.onMeasure(widthMeasureSpec, heightMeasureSpec); 
    // Log.i("Seekbar", "onMeasure"); 
    if (labelBackground != null) { 

     viewWidth = getMeasuredWidth(); 
     barHeight = getMeasuredHeight() - getPaddingTop() 
       - getPaddingBottom(); 
     setMeasuredDimension(viewWidth + labelBackground.getWidth(), 
       barHeight + labelBackground.getHeight()/2); 
    } 

} 

@Override 
protected void onDraw(Canvas canvas) { 
    canvas.save(); 
    if (labelBackground != null) { 
     barBounds.left = getPaddingLeft(); 
     barBounds.top = (int) (labelBackground.getHeight()/2f); 
     barBounds.right = barBounds.left + viewWidth - getPaddingRight() 
       - getPaddingLeft(); 
     barBounds.bottom = barBounds.top + barHeight - getPaddingBottom() 
       - getPaddingTop(); 

     progressPosX = barBounds.top 
       + ((float) this.getProgress()/(float) this.getMax()) 
       * barBounds.height() + getTopPaddingOffset(); 

     labelPos.y = getBottom() - (int) progressPosX - labelOffset 
       + (int) (getProgress() * 0.1f); 
     labelPos.x = getPaddingLeft(); 

     progressDrawable = getProgressDrawable(); 

     progressDrawable.setBounds(barBounds.left, barBounds.top, 
       barBounds.right, getBottom()); 

     progressDrawable.draw(canvas); 

     String pro = getProgress() * multiplier + ""; 
     if (expression != null) { 
      pro = pro.concat(expression); 
     } 
     labelTextPaint.getTextBounds(pro, 0, pro.length(), labelTextRect); 

     canvas.drawBitmap(labelBackground, labelPos.x, labelPos.y, 
       labelBackgroundPaint); 

     canvas.drawText(pro, labelPos.x + labelBackground.getWidth()/2 
       - labelTextRect.width()/2 + 15, labelPos.y 
       + labelBackground.getHeight()/2 + labelTextRect.height() 
       /2 - 5, labelTextPaint); 

    } 
    canvas.restore(); 
} 

@Override 
public boolean onTouchEvent(MotionEvent event) { 
    invalidate(); 
    return super.onTouchEvent(event); 

} 

public void setOnSeekBarChangeListener(
     com.tokaracamara.android.verticalslidevar.DemoSeek.OnSeekBarChangeListener onSeekBarChangeListener) { 
    mOnSeekBarChangeListener = (OnSeekBarChangeListener) onSeekBarChangeListener; 
} 

@Override 
void onStartTrackingTouch() { 
    if (mOnSeekBarChangeListener != null) { 
     mOnSeekBarChangeListener.onStartTrackingTouch(this); 
    } 
} 

@Override 
void onStopTrackingTouch() { 
    if (mOnSeekBarChangeListener != null) { 
     mOnSeekBarChangeListener.onStopTrackingTouch(this); 
    } 
} 


private int multiplier = 1; 

public void setMultiplier(int multiplier) { 
    this.multiplier = multiplier; 
} 

public int getMultiplier() { 
    return multiplier; 
} 

public void setExpression(String expression) { 
    this.expression = expression.trim(); 
} 

public String getExpression() { 
    return expression; 
} 

}

Создать Xml Like This:

<com.tokaracamara.android.verticalslidevar.DemoSeek 
      android:id="@+id/v_four_university" 
      android:layout_width="@dimen/vs_width" 
      android:layout_height="match_parent" 
      android:clickable="false" 
      android:focusable="false" 
      android:longClickable="false" 
      android:progress="50" 
      android:progressDrawable="@drawable/progress_vertical" 
      android:saveEnabled="false" 
      android:thumb="@drawable/your thumb" />
