public class RotateTextView extends TextView {
private static final int[] textDegree = new int[]{R.attr.degree, R.attr.transX, R.attr.transY};
private int degree;
private int transX;
private int transY;
public RotateTextView(Context context, AttributeSet attrs) {
super(context, attrs);
TypedArray ta = context.obtainStyledAttributes(attrs, textDegree);
degree = ta.getInteger(0, 0);
transX = ta.getDimensionPixelSize(1, 0);
transY = ta.getDimensionPixelSize(2, 0);
ta.recycle();
}
@Override
protected void onDraw(Canvas canvas) {
canvas.save();
canvas.rotate(degree, getMeasuredWidth() / 2, getMeasuredHeight() / 2);
canvas.translate(transX, transY);
super.onDraw(canvas);
canvas.restore();
}
}
