我使用它来通过textView
进行调整textView.setPaintFlags(textView.getPaintFlags()| Paint.STRIKE_THRU_TEXT_FLAG);
但现在我想个性化颜色并将其旋转45°以适应内容的对角线。
我绑的是什么:
我虽然关于扩展textview小部件并覆盖onDraw方法..但我在设计时非常初学......
所以有什么帮助如何在textView上绘制红色(彩色)旋转线?

@Override
protected void onDraw(Canvas canvas) {
Paint paint = new Paint();
paint.setColor(strikeThroughColor);
paint.setStyle(Paint.Style.FILL);
paint.setFakeBoldText(true);
paint.setStrikeThruText(true);
paint.setStrokeWidth(strikeThroughWidth);
paint.setFlags(Paint.ANTI_ALIAS_FLAG);
super.onDraw(canvas);
float width = getWidth();
float height = getHeight();
canvas.drawLine(width / 10, height / 10, (width - width / 10), (height - height / 10), paint);
}

为此,请按照以下步骤操作:
View
类例如:
class CustomTextView extends View {
private int mColor;
private int mRotationAngle, mRotationW, mRotationH;
private String mText;
public CustomTextView(Context context) {
super(context);
// set default parameters
mColor = Color.WHITE;
mRotationAngle = 0;
}
public void SetColor(int newcolor) {
mColor = newcolor;
this.invalidate();
}
public void SetRotation(int newangle, int neww, int newh) {
mRotationAngle = newangle;
mRotationW = neww;
mRotationH = newh;
this.invalidate();
}
public void SetText(String newtext) {
mText = newtext;
this.invalidate();
}
@Override
protected void onDraw(Canvas canvas) {
Paint paint = new Paint();
paint.setStyle(Paint.Style.FILL);
canvas.rotate(mRotationAngle,mRotationW,mRotationH);
canvas.drawText(mText, 0, 0, paint);
super.onDraw(canvas);
}
}

使用以下方法,您可以实现此功能,而无需在Java代码中弄乱UI:
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentStart="true"
android:layout_centerVertical="true">
<TextView
android:id="@+id/textview1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentStart="true"
android:text="$99"
android:textSize="12sp" />
<View
android:layout_width="0dp"
android:layout_height="1dp"
android:layout_centerVertical="true"
android:layout_alignLeft="@+id/textview1"
android:layout_alignRight="@+id/textview1"
android:background="@color/fav_dark_red_color" />
</RelativeLayout>
