 mTextPaint = new TextPaint();        mTextPaint.setFlags(Paint.ANTI_ALIAS_FLAG);        mTextPaint.setTextAlign(Paint.Align.LEFT);                mTextPaint.setTextSize(mExampleDimension);        mTextPaint.setColor(mExampleColor);        mTextWidth = mTextPaint.measureText(mExampleString);        Paint.FontMetrics fontMetrics = mTextPaint.getFontMetrics();        mTextHeight = fontMetrics.bottom -fontMetrics.top;        mTop = fontMetrics.top;

 int paddingLeft = getPaddingLeft();        int paddingTop = getPaddingTop();        int paddingRight = getPaddingRight();        int paddingBottom = getPaddingBottom();        int contentWidth = getWidth() - paddingLeft - paddingRight;        int contentHeight = getHeight() - paddingTop - paddingBottom;        // Draw the text.        canvas.drawText(mExampleString,                paddingLeft + (contentWidth - mTextWidth) / 2,                paddingTop + (contentHeight - mTextHeight) / 2 - mTop,                mTextPaint);
