Android--去除EditText边框,加入下划线
<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" android:layout_width="fill_parent" android:layout_height="fill_parent" > <!--注意名称 --> <com.marine.study.LineEditText android:id="@+id/myEdit" android:layout_width="fill_parent" android:layout_height="wrap_content" style="?android:attr/textViewStyle" android:background="@null" android:textColor="@null" /> </LinearLayout>
当中background,能够设置成其它颜色等
textColor不一定要是null,能够设置字体颜色
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(); // 依据行数循环画线 for (int i = 0; i < lineCount; i++) { int lineY = (i + 1) * lineHeight; canvas.drawLine(0, lineY, this.getWidth(), lineY, paint); } } }
