I made vertical seekbar. Now I want to display progress on seekbar thumb. I successfully implemented this but now my text is showing below seekbar thumb. I want to draw text on top of seekbar thumb How can I achieve this? I also add my code
public class TextThumbSeekBar extends SeekBar {
public TextThumbSeekBar(Context context) {
super(context);
}
private int mThumbSize;
private TextPaint mTextPaint;
public TextThumbSeekBar(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
mThumbSize = 50;
mTextPaint = new TextPaint();
mTextPaint.setColor(Color.BLACK);
mTextPaint.setTextSize(50);
mTextPaint.setTypeface(Typeface.DEFAULT_BOLD);
mTextPaint.setTextAlign(Paint.Align.CENTER);
}
public TextThumbSeekBar(Context context, AttributeSet attrs) {
super(context, attrs);
mThumbSize = 50;
mTextPaint = new TextPaint();
mTextPaint.setColor(Color.BLACK);
mTextPaint.setTextSize(50);
mTextPaint.setTypeface(Typeface.DEFAULT_BOLD);
mTextPaint.setTextAlign(Paint.Align.CENTER);
}
protected void onSizeChanged(int w, int h, int oldw, int oldh) {
super.onSizeChanged(h, w, oldh, oldw);
}
#Override
public synchronized void setProgress(int progress) // it is necessary for calling setProgress on click of a button
{
super.setProgress(progress);
onSizeChanged(getWidth(), getHeight(), 0, 0);
}
#Override
protected synchronized void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
super.onMeasure(heightMeasureSpec, widthMeasureSpec);
setMeasuredDimension(getMeasuredHeight(), getMeasuredWidth());
}
protected void onDraw(Canvas c) {
String progressText = String.valueOf(getProgress());
c.drawText(progressText, getThumb().getBounds().centerY(), getHeight() - getThumb().getBounds().centerX(), mTextPaint);
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:
super.onTouchEvent(event);
setProgress(getMax() - (int) (getMax() * event.getY() / getHeight()));
onSizeChanged(getWidth(), getHeight(), 0, 0);
break;
case MotionEvent.ACTION_CANCEL:
break;
}
return true;
}
}
Here how I used this class in my xml
<demo.smart.com.smartchargeboxdemoapp.TextThumbSeekBar
android:max="100"
android:thumb="#drawable/shape_seek_bar_text_thumb"
android:layout_gravity="center"
android:id="#+id/seekbar"
android:layout_width="30dp"
android:layout_height="match_parent" />
And here's the result that I get
Although the question is old, I did in this case the thumbTint transparent and before the drawText I did 'drawRect' to draw my thumb that won't be rotated.
Hope I helped.
I am using a custom Vertical Seekbar and everything works great, except for the Thumb highlight.
As I scroll the left seekbar up and down, the thumb highlight continues to scroll left to right at the top of the screen as if the seekbar is still horizontal. My custom vertical seekbar is as follows:
public class VerticalSeekBar extends SeekBar {
protected OnSeekBarChangeListener changeListener;
public VerticalSeekBar(Context context) {
super(context);
}
public VerticalSeekBar(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
public VerticalSeekBar(Context context, AttributeSet attrs) {
super(context, attrs);
}
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());
}
#Override
public synchronized void setProgress(int progress) {
super.setProgress(progress);
onSizeChanged(getWidth(), getHeight(), 0, 0);
}
#Override public void setOnSeekBarChangeListener(OnSeekBarChangeListener mListener)
{
this.changeListener = mListener;
}
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:
setProgress(getMax() - (int) (getMax() * event.getY() / getHeight()));
if (changeListener != null)
changeListener.onStartTrackingTouch(this);
setSelected(true);
setPressed(true);
break;
case MotionEvent.ACTION_UP:
if (changeListener != null)
changeListener.onStopTrackingTouch(this);
setSelected(false);
setPressed(false);
break;
case MotionEvent.ACTION_MOVE:
int i=getMax() - (int) (getMax() * event.getY() / getHeight());
setProgress(i);
onSizeChanged(getWidth(), getHeight(), 0, 0);
if (changeListener != null)
changeListener.onProgressChanged(this, i, true);
setPressed(true);
setSelected(true);
break;
case MotionEvent.ACTION_CANCEL:
break;
}
return true;
}
}
I can eliminate the highlight entirely by removing
setSelected(true);
setPressed(true);
But ideally I want to keep the standard design pattern and have the highlight follow where the thumb is. Is there anyway to access the location and position of the highlight so I can rotate that as well?
I had the same question and came across this similar post for an answer:
Android SeekBar custom rectangle thumb visual bug
Set the Background to null. I added "setBackground(null);" to the constructor of my extended SeekBar class, but the suggested solution does this in the activity.xml file under the "SeekBar" section.
I am working on a app where I am using both Horizontal and Vertical seekbar with showing popup at thumb location.
For horizontal seekbar both the things are fine.
But when we rotate seekbar by -90/270 degree, then the popup is not showing on proper location(above the thumb)
The problem is we try to get bound of Seekbar thumb for vertical position but i am getting bound of horizontal position.
Any help is appreciable.
Try this vertical seekbar. As you see in **setProgress(int progress)** method thumb position will update, automatically. Good
luck

Hello i'm trying to make an equalizer for my app but i can't figure out how to make the buttons. I don't really know how to explain myself so here is a picture that reveals more than my words:
Do i need animations? Can you guys point me in the right direction?
Thanks in advance.
There's a nice tutorial here for creating an odometer widget. It's not at all the look you want, but many (most) of the same issues apply, including custom rendering, dealing with touch events, and wiring up a series of sub-widgets into a larger control. It's the first thing I thought of when I saw your graphic.
This is simple vertical seekBar....
public class SimpleVerticalSeekBar extends SeekBar {
public SimpleVerticalSeekBar(Context context) {
super(context);
}
public SimpleVerticalSeekBar(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
public SimpleVerticalSeekBar(Context context, AttributeSet attrs) {
super(context, attrs);
}
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());
}
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:
setProgress(getMax() - (int) (getMax() * event.getY() / getHeight()));
onSizeChanged(getWidth(), getHeight(), 0, 0);
break;
case MotionEvent.ACTION_CANCEL:
break;
}
return true;
}
}
I think you mean a SeekBar. It's the JSlider of Android.
I've implemented the commonly-pointed-to VerticalSeekBar post here. As it is, the SeekBar operates a little quirky. Here is my slightly adapted onTouchEvent() from that example:
public boolean onTouchEvent(MotionEvent event)
{
xPos = event.getX();
yPos = event.getY();
oOffset = this.getThumbOffset();
oProgress = this.getProgress();
//Code from example - Not working
//this.setThumbOffset( progress * (this.getBottom()-this.getTop()) );
this.setProgress((int)(29*yPos/this.getBottom()));
return true;
}
I've managed to implement one VerticalSeekBar in which the progress updates as expected and is fully-functional, but the thumb does not follow suit. This is only a graphical glitch, so I'm overlooking it for now. But, it would be nice to have that working. This SeekBar has max = 20.
However, I tried implementing another VerticalSeekBar with max = 1000. Obviously, it uses the same code, so you'd assume the same behavior. I'm only able to achieve a progress of 0~35, even as my finger slides beyond the SeekBar and eventually off the screen. If I just tap near the end of the progress bar (which should be progress ~ 900) it returns a progress of about 35 and the yellow progress bar reflects that value by staying near the top.
My question is: Does anyone have a link to a working vertical SeekBar, or know how to adapt this particular example?
Here is a working VerticalSeekBar implementation:
package android.widget;
import android.content.Context;
import android.graphics.Canvas;
import android.util.AttributeSet;
import android.view.MotionEvent;
public class VerticalSeekBar extends SeekBar {
public VerticalSeekBar(Context context) {
super(context);
}
public VerticalSeekBar(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
public VerticalSeekBar(Context context, AttributeSet attrs) {
super(context, attrs);
}
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());
}
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:
setProgress(getMax() - (int) (getMax() * event.getY() / getHeight()));
onSizeChanged(getWidth(), getHeight(), 0, 0);
break;
case MotionEvent.ACTION_CANCEL:
break;
}
return true;
}
}
To implement it, create a new class in your project, choosing the right package:
There, paste the code and save it. Now use it in your XML layout:
<android.widget.VerticalSeekBar
android:id="#+id/seekBar1"
android:layout_width="wrap_content"
android:layout_height="200dp"
/>
The code given in the accepted answer didn't intercept the onStartTrackingTouch and the onStopTrackingTouch events, so I've modified it to have more control over this two events.
Here is my code:
public class VerticalSeekBar extends SeekBar {
private OnSeekBarChangeListener myListener;
public VerticalSeekBar(Context context) {
super(context);
}
public VerticalSeekBar(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
public VerticalSeekBar(Context context, AttributeSet attrs) {
super(context, attrs);
}
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());
}
#Override
public void setOnSeekBarChangeListener(OnSeekBarChangeListener mListener){
this.myListener = mListener;
}
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:
if(myListener!=null)
myListener.onStartTrackingTouch(this);
break;
case MotionEvent.ACTION_MOVE:
setProgress(getMax() - (int) (getMax() * event.getY() / getHeight()));
onSizeChanged(getWidth(), getHeight(), 0, 0);
myListener.onProgressChanged(this, getMax() - (int) (getMax() * event.getY() / getHeight()), true);
break;
case MotionEvent.ACTION_UP:
myListener.onStopTrackingTouch(this);
break;
case MotionEvent.ACTION_CANCEL:
break;
}
return true;
}
}
I had problems while using this code with setProgress method. To solve them I suggest overriding setProgress and adding onSizeChanged call to it.
I had problem while using this code with setProgress method. To solve them I suggest overriding setProgress and adding onSizeChanged call to it.Added code here ..
private int x,y,z,w;
protected void onSizeChanged(int w, int h, int oldw, int oldh) {
super.onSizeChanged(h, w, oldh, oldw);
this.x=w;
this.y=h;
this.z=oldw;
this.w=oldh;
}
#Override
public synchronized void setProgress(int progress) {
super.setProgress(progress);
onSizeChanged(x, y, z, w);
}
selected hover actions are performed by adding the following code:
1.setPressed(true);setSelected(true);//Add this in ACTION_DOWN
2.setPressed(false);setSelected(false);//Add this in ACTION_UP
And Write code for selected hover options in ur xml.
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true"
android:state_window_focused="true"
android:drawable="#drawable/thumb_h" />
<item android:state_selected="true"
android:state_window_focused="true"
android:drawable="#drawable/thumb_h" />
<item android:drawable="#drawable/thumb" />
</selector>
This is working for me...
Thanks to Paul Tsupikoff, Fatal1ty2787 and Ramesh for this excellent code.
Personally, I wanted a vertical slider that is upside-down compared to the given code. In other words, the value increases, rather than decreases, the lower the thumb. Changing four lines seems to have taken care of this.
First, I changed the onDraw() method as originally given by Paul. The rotate() and translate() calls now have these arguments:
c.rotate(90);
c.translate(0, -getWidth());
Then I made two changes to the ACTION_MOVE case in onTouchEvent() as given by Fatal1ty2787. The call to setProgress() now looks like this:
setProgress((int) (getMax() * event.getY() / getHeight()));
Finally, the call to onProgressChanged() looks like this:
myListener.onProgressChanged(this, (int) (getMax() * event.getY() / getHeight()), true);
Now, if only Google shared our interest in this feature....
For API 11 and later, can use seekbar's XML attributes(android:rotation="270") for vertical effect.
<SeekBar
android:id="#+id/seekBar1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:rotation="270"/>
For older API level (ex API10),use:
https://github.com/AndroSelva/Vertical-SeekBar-Android
Another idea could be to change the X and Y coordinates of the MotionEvent and pass them to the super-implementation:
public class VerticalSeekBar extends SeekBar {
public VerticalSeekBar(Context context) {
super(context);
}
public VerticalSeekBar(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
public VerticalSeekBar(Context context, AttributeSet attrs) {
super(context, attrs);
}
#Override
public boolean onTouchEvent(MotionEvent event) {
if (!isEnabled()) {
return false;
}
float x = (getHeight() - event.getY()) * getWidth() / getHeight();
float y = event.getX();
MotionEvent verticalEvent = MotionEvent
.obtain(event.getDownTime(), event.getEventTime(), event.getAction(), x, y,
event.getPressure(), event.getSize(), event.getMetaState(),
event.getYPrecision(), event.getXPrecision(), event.getDeviceId(),
event.getEdgeFlags());
return super.onTouchEvent(verticalEvent);
}
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());
}
protected void onSizeChanged(int w, int h, int oldw, int oldh) {
super.onSizeChanged(h, w, oldh, oldw);
}
}
In this case it is not necessary to call the setProgress(int) method and therefore you could use the boolean-flag "fromUser" in OnSeekBarChangeListener.onProgressChanged() to determine if the seeking was produced by an user interaction.
Based on Paul Tsupikoff's answer, here is the AppCompatVerticalSeekBar:

setMeasuredDimension(getMeasuredHeight(), getMeasuredWidth());
}

canvas.translate(-getHeight(), 0);
super.onDraw(canvas);
}

switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:

case MotionEvent.ACTION_UP: {
setProgress(getMax() - (int) (getMax() * event.getY() / getHeight()));
onSizeChanged(getWidth(), getHeight(), 0, 0);
break;
}
case MotionEvent.ACTION_CANCEL: {
break;
}
}
return true;
}
}
