How to make a vertical SeekBar in Android?
Here is a very good implementation of vertical seekbar.
Have a look.
http://560b.sakura.ne.jp/android/VerticalSlidebarExample.zip
And Here is my own implementation for Vertical and Inverted Seekbar based on this
https://github.com/AndroSelva/Vertical-SeekBar-Android
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;
}
How can I get a working vertical SeekBar in Android?
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"
/>
Vertical Seekbar in Android
Here is a good code to align seek-bar vertically:
Vertical Seekbar
Vertical seekbar showing as a horizontal one in Android Studio
You can try the following library to create a custom vertical seekbar,
dependencies {
compile 'com.h6ah4i.android.widget.verticalseekbar:verticalseekbar:0.7.0'
}
To use in your xml layout,
<!-- This library requires pair of the VerticalSeekBar and VerticalSeekBarWrapper classes -->
<com.h6ah4i.android.widget.verticalseekbar.VerticalSeekBarWrapper
android:layout_width="wrap_content"
android:layout_height="150dp">
<com.h6ah4i.android.widget.verticalseekbar.VerticalSeekBar
android:id="@+id/mySeekBar"
android:layout_width="0dp"
android:layout_height="0dp"
android:splitTrack="false"
app:seekBarRotation="CW90" /> <!-- Rotation: CW90 or CW270 -->
</com.h6ah4i.android.widget.verticalseekbar.VerticalSeekBarWrapper>
Reference: https://github.com/h6ah4i/android-verticalseekbar
Update: To customize the seekbar, you need to add the android:thumb & android:progressDrawable. First of all, Create the following drawables into the drawable folder,
seekbar_background
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle">
<solid android:color="#404040" />
<corners android:radius="40dp" />
</shape>
</item>
</selector>
seekbar_progress
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="line">
<stroke
android:width="4dp"
android:color="#777777" />
</shape>
seekbar
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="@android:id/background"
android:drawable="@drawable/seekbar_background"
android:left="2dp">
</item>
<item android:id="@android:id/progress">
<clip android:drawable="@drawable/seekbar_progress" />
</item>
</layer-list>
and finally,
seekbar_thumb
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="oval">
<solid android:color="#7FD319" />
<size
android:width="15dp"
android:height="15dp" />
</shape>
</item>
</layer-list>
Now update your seekbar with the thumb & progreeDrawable,
<!-- This library requires pair of the VerticalSeekBar and VerticalSeekBarWrapper classes -->
<com.h6ah4i.android.widget.verticalseekbar.VerticalSeekBarWrapper
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="center">
<com.h6ah4i.android.widget.verticalseekbar.VerticalSeekBar
android:id="@+id/opacity_seek"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@null"
android:progressDrawable="@drawable/seekbar"
android:splitTrack="false"
android:thumb="@drawable/seekbar_thumb_green"
app:seekBarRotation="CW270" /> <!-- Rotation: CW90 or CW270 -->
</com.h6ah4i.android.widget.verticalseekbar.VerticalSeekBarWrapper>
How to make vertical seekbar with progress text as thumb
Update to Khemraj's answer
Actually changing the thumb is the simple trick as said by Khemraj. But the problem is when rotating the canvas all its contents will rotate(simple logic). When updating the thumb also will reflect this problem. So the simple thing is to make a rotated CustomTextView
.
Method to make thumb
public Drawable getThumb(int progress) {
int width = getWidth();
((TextView) mThumbView.findViewById(R.id.tvProgress)).setText(String.format(Locale.getDefault(), "%d%%", progress));
mThumbView.measure(View.MeasureSpec.UNSPECIFIED, View.MeasureSpec.UNSPECIFIED);
Bitmap bitmap = Bitmap.createBitmap(mThumbView.getMeasuredWidth(), mThumbView.getMeasuredHeight(), Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(bitmap);
mThumbView.layout(0, 0, mThumbView.getMeasuredWidth(), mThumbView.getMeasuredHeight());
mThumbView.draw(canvas);
return new BitmapDrawable(getResources(), bitmap);
}
The layout
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center">
<ImageView
android:layout_marginTop="30dp"
android:id="@+id/imageView6"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/seek_thumb_gray"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<com.samsung.lighting.presentation.ui.custom_views.RotatedTextView
android:id="@+id/tvProgress"
android:layout_width="wrap_content"
android:layout_height="40dp"
android:gravity="center"
android:text="20%"
android:textColor="#000000"
android:textSize="12sp"
app:angle="90"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="@+id/imageView6" />
</android.support.constraint.ConstraintLayout>
The
RotatedTextView
public class RotatedTextView extends AppCompatTextView {
private int mRotationAngle = 90;
@Override
protected void onDraw(Canvas canvas) {
if (mRotationAngle == 90) {
canvas.rotate(mRotationAngle);
canvas.translate(0, -getWidth());
} else if (mRotationAngle == -90) {
canvas.rotate(mRotationAngle);
canvas.translate(-getHeight(), 0);
}
super.onDraw(canvas);
}
}
So first we will rotate the Text to 90 or -90 degrees and set as thumb to VerticalSeekBar
and in vertical seekbar rotate the canvas to 90 or -90 degrees. So finally we will get the actual result
Here I posted the working example.
Thanks, Khemraj
How to make a vertical range seekbar?
ok I found this library:
https://github.com/edmodo/range-bar
<com.edmodo.rangebar.RangeBar
android:id="@+id/rb"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:rotation="90"
app:tickCount="16"
/>
int left_index = rb.getLeftIndex();
int right_index = rb.getRightIndex();
hope it will be usefull
