android自定义带下划线EditText

heisedeyueya

最近做项目，需要用到带下划线的EditText，通过学习Android提供的示例Notepad，对其进行小小的改动，解决文字压线的问题，但是光标压线的问题没有解决，希望以后能够解决，效果和代码如下：
效果图：

代码：
public class UnderlineEditText extends EditText {private static final String TAG = "UnderlineEditText";private Paint mPaint;private Rect mRect;private float mult = 1.5f;private float add = 2.0f;public UnderlineEditText(Context context, AttributeSet attrs) {super(context, attrs);init();}public UnderlineEditText(Context context) {super(context);init();}private void init() {mRect = new Rect();mPaint = new Paint();mPaint.setStyle(Paint.Style.STROKE);mPaint.setColor(Color.GRAY);mPaint.setAntiAlias(true);this.setLineSpacing(add, mult);}@Overridepublic void onDraw(Canvas canvas) {Log.d(TAG, "func [onDraw]");int count = getLineCount();for (int i = 0; i < count; i++) {getLineBounds(i, mRect);int baseline = (i + 1) * getLineHeight();canvas.drawLine(mRect.left, baseline, mRect.right, baseline, mPaint);}super.onDraw(canvas);}}
