问题 I'm using DrawText to draw text onto a DBGrid canvas. The text comes from the database. But when the string contains an ampersand (&) it treats it as an alt shortcut and underlines it.

Code I have used : customPath2.addArc(mCircleRectF, 30F, 64.28F); customPaint2.setAntiAlias(true); customPaint2.setDither(true); customPaint2.setStrokeWidth(mCircleStrokeWidth); customPaint2.setColor(Color.parseColor("#93BE66")); customPaint2.setStyle(Paint.Style.STROKE); customPaint2.setStrokeCap(Paint.Cap.ROUND);

问题 I can't seem to get text positioned in the same places on screens of different resolution. The problem is the text is floating, it's not part of any layout type of control.

Despite that, the text appears in a different location on different resolution screens. So I'm stuck approximating the location for certain resolutions and this gets messy really fast. How
