- <span style="font-family: Arial, Helvetica, sans-serif;"><?xml version="1.0" encoding="utf-8"?> </span>
- <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

其中background，可以设置成其他颜色等
textColor不一定要是null，可以设置字体颜色
加下划线
- public class LineEditText extends EditText {
- // 画笔 用来画下划线
- private Paint paint;
- public LineEditText(Context context, AttributeSet attrs) {
- super(context, attrs);
- paint = new Paint();
- paint.setStyle(Paint.Style.STROKE);
- paint.setColor(Color.RED);
- // 开启抗锯齿 较耗内存
- paint.setAntiAlias(true);
- }
- @Override
- protected void onDraw(Canvas canvas) {
- super.onDraw(canvas);
- // 得到总行数
- int lineCount = getLineCount();
- // 得到每行的高度
- int lineHeight = getLineHeight();
- // 根据行数循环画线
- for (int i = 0; i < lineCount; i++) {
- int lineY = (i + 1) * lineHeight;
- canvas.drawLine(0, lineY, this.getWidth(), lineY, paint);
- }
- }
- }
