参考技术A bootstrap如何实现横向布局Bootstrap学习笔记(二) 表单
源码分析:
单中常见的元素主要包括:文本输入框、下拉选择框、单选按钮、复选按钮、文本域和按钮等。
Bootstrap框架默认的表单是垂直显示风格,在Bootstrap框架中要实现水平表单效果,必须满足以下两个条件:
效果:
在Bootstrap框架中实现内联表单,只需要在<form>元素中添加类名“form-inline”即可。
CSS之使用display:inline-block来布局
在input前面添加一个label标签时,会导致input换行显示。如果你必须添加这样的一个label标签,并且不想让input换行,你需要将label标签也放在容器“form-group”中。
bootstrap栅栏系统css中的col-xs- 、col-sm- 、col-md-* 的意义以及 bootstrap一个标签中,同时有 col-xs , col-sm , col-md , col-lg的理解
可以响应式的设置大小。
Bootstrap标签(label)的使用

BottomSheetDialogFragment实现地图导航弹窗效果
需求如下:从服务器查询列表在地图上弹窗显示,首次只能显示两条Item,下滑隐藏,上滑动铺满位于titleBar下,点击标记物显示详情,详情内可以点击查看列表
看效果图
首先想到的是NetScrollView CoordinatorLayout Behavior,当然还有BottomSheet系列,个人比较倾向于BottomSheetDialogFragment,不用在layout 绑定behavior操作,就像一般的Fragment dialog使用一样即可
相关BottomSheetDialogFragment的使用操作先推荐一篇文章科普,很有必要看哟

根据上面这边博客我先搞一个BaseBottomSheetFragment基类,方便其他地方调用

使用时注意拷贝注释掉的style,关于一些view高度测量相关的函数提取到BottomSheetDelegate类代理

var minPeekHeight = 0
if (headerLayoutResId == -1) {
minPeekHeight = getMeasuredHeightWithResId(context!!,itemLayoutResId) * itemCount
} else {

}
return minPeekHeight
}
/**
* 测量view 高度,布局使用精确值
*/
fun getMaxHeight(activity: Activity,titleBarLayoutResId: Int): Int {
//系统屏幕高度
val outMetrics = DisplayMetrics()
activity?.windowManager?.defaultDisplay?.getMetrics(outMetrics)
val heightPixels = outMetrics.heightPixels
//自定义标题栏背景向上填充statusBar 高度

//兼容凹凸屏幕
var max = 0
var notchSize = activity!!.let { NotchScreenUtil.getNotchHeight(it) }
if (notchSize != 0) {
max = heightPixels - itemView.measuredHeight - statusBarHeight + notchSize
} else {

}
return max
}
/**

Tip: 这里的测量模式是根据自己布局写死的,具体使用具体修改,maxHeight的计算是根据自己UI实现的,也是具体界面具体修改,虚拟按键高度获取提供了暂未使用
这里面还做了关于华为、vivo、oppo手机凹凸屏幕高度获取适配NotchScreenUtil

最后再提供一个函数关于上图效果三角形旋转的代码块(如果使用两张图就可以忽略了)
private fun rotateBitmap(bm: Bitmap, orientationDegree: Float): Bitmap? {
//方便判断,角度都转换为正值
var degree = orientationDegree
if (degree < 0) {
degree = 360 + orientationDegree
}
val srcW = bm.width
val srcH = bm.height
val m = Matrix()
m.setRotate(degree, srcW.toFloat() / 2, srcH.toFloat() / 2)
val targetX: Float
val targetY: Float
var destH = srcH
var destW = srcW
//根据角度计算偏移量,原理不明
if (degree == 90f) {
targetX = srcH.toFloat()
targetY = 0f
destH = srcW
destW = srcH
} else if (degree == 270f) {
targetX = 0f
targetY = srcW.toFloat()
destH = srcW
destW = srcH
} else if (degree == 180f) {
targetX = srcW.toFloat()
targetY = srcH.toFloat()
} else {
return bm
}
val values = FloatArray(9)
m.getValues(values)
val x1 = values[Matrix.MTRANS_X]
val y1 = values[Matrix.MTRANS_Y]
m.postTranslate(targetX - x1, targetY - y1)
//注意destW 与 destH 不同角度会有不同
val bm1 = Bitmap.createBitmap(destW, destH, Bitmap.Config.ARGB_8888)
val paint = Paint()
val canvas = Canvas(bm1)
canvas.drawBitmap(bm, m, paint)
return bm1
}
有以上代码我相信你也可以轻松实现上图效果,源码暂不上传了
