Android: vertical RatingBar?

Question

How can I rotate RatingBar? Is there an example for a vertical custom RatingBar?

Answer 1

This is a sample code for a vertical scale ...

public class VerticalRatingBar extends RatingBar { private int x, y, z, w; @Override protected void drawableStateChanged() { // TODO Auto-generated method stub super.drawableStateChanged(); } public VerticalRatingBar(Context context) { super(context); } public VerticalRatingBar(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); } public VerticalRatingBar(Context context, AttributeSet attrs) { super(context, attrs); } 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 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: setSelected(true); setPressed(true); break; case MotionEvent.ACTION_MOVE: setProgress(getMax() - (int) (getMax() * event.getY() / getHeight())); onSizeChanged(getWidth(), getHeight(), 0, 0); break; case MotionEvent.ACTION_UP: setSelected(false); setPressed(false); break; case MotionEvent.ACTION_CANCEL: break; } return true; } @Override public synchronized void setProgress(int progress) { if (progress >= 0) super.setProgress(progress); else super.setProgress(0); onSizeChanged(x, y, z, w); } }

There is a setRotation method there , which I hope will achieve what you are after.
