android p状态栏，插入sim卡，关闭数据流量，状态栏卡图标右下角有Ｘ图标

需要修改的文件
SettingsLib 模块下的SignalDrawable.java

上述代码块中的

        } else if (mState == STATE_CUT) {            float cut = (CUT_OUT * width);            mFullPath.moveTo(width - padding, height - padding);            mFullPath.rLineTo(-cut, 0);            mFullPath.rLineTo(0, -cut);            mFullPath.rLineTo(cut, 0);            mFullPath.rLineTo(0, cut);        }        if (mState == STATE_CUT) {            mXPath.reset();            mXPath.moveTo(X_PATH[0][0] * width, X_PATH[0][1] * height);            for (int i = 1; i < X_PATH.length; i++) {                mXPath.rLineTo(X_PATH[i][0] * width, X_PATH[i][1] * height);            }            canvas.drawPath(mXPath, mForegroundPaint);        }

注释调就可以了
