Android实战场景 - 用Kotlin写个能让我进步的Dialog

去年接到过一个小需求，一个简简单单的弹框，不论是用dialog、popupWindow都能很轻松的实现；之所以记录是因为每一次都感觉好像进步了一点点…

弹框相关Blog

一个小小需求，我使用了俩种实现方式，其一为我的惯性常规实现，其二为项目中所学的进阶实现，用到的新技术也多一点

记录原因

  • kotlin 写弹框
  • 命令式UI、声明式UI 自定义弹框视图
  • 富文本样式
  • SpannableStringBuilder 扩展函数
  • 典型的弹框场景

功能分析

常规实现

按照我的开发习惯，我一般是先画 dialog 的 UI...

弹框样式

提示：TypefaceTextView 是 splitties 库提供的控件，其继承自 AppCompatTextView 的视图类，如不使用可自行用TextView，加粗用自带的即可

该处重写主要在其内部添加了设置字体粗度的功能

package xxx

import android.content.Context
import android.graphics.Canvas
import android.graphics.Paint
import android.util.AttributeSet
import androidx.appcompat.widget.AppCompatTextView

open class TypefaceTextView @JvmOverloads constructor(context: Context, attrs: AttributeSet? = null, defStyleAttr: Int = 0) :
    AppCompatTextView(context, attrs, defStyleAttr) {

    private var mTypefaceScale: Float = 0.0f

    enum class TypefaceScale {
        MEDIUM, MEDIUM_SMALL, DEFAULT,
    }

    override fun onDraw(canvas: Canvas?) {
        if (mTypefaceScale == 0f) {
            return super.onDraw(canvas)
        }
        val strokeWidth = paint.strokeWidth
        val style = paint.style
        paint.strokeWidth = mTypefaceScale
        paint.style = Paint.Style.FILL_AND_STROKE
        super.onDraw(canvas)
        paint.strokeWidth = strokeWidth
        paint.style = style
    }

    internal fun setTypefaceScale(scale: TypefaceScale = TypefaceScale.DEFAULT) {
        mTypefaceScale = when (scale) {
            TypefaceScale.DEFAULT -> 0.0f
            TypefaceScale.MEDIUM_SMALL -> 0.6f
            TypefaceScale.MEDIUM -> 1.1f
        }
        invalidate()
    }

}

按钮样式

我直接copy项目已有的shape，原始是支持按压和平时的俩种显示状态，因为我没有这项功能，所以我注释掉了…

shape_dialog_discount_confirm_bg

调用方式

    var view = LayoutInflater.from(activity).inflate(R.layout.dialog_layout_discount, null)
    val alertDialog = AlertDialog.Builder(activity).setCancelable(false).setView(view).create()
    alertDialog.window?.setBackgroundDrawable(ColorDrawable(0))
    var title = view.findViewById<TypefaceTextView>(R.id.title)
    title.typefaceScale = TypefaceScale.MEDIUM_SMALL
    //富文本
    var content = view.findViewById<TextView>(R.id.content)
    val contentText = SpannableStringBuilder("您还未领取0折购基打折卡，无法享受\n0折购基的优惠，是否现在去领取？")
    contentText.setSpan(AbsoluteSizeSpan(13, true), 0, 4, Spannable.SPAN_INCLUSIVE_INCLUSIVE)
    contentText.setSpan(AbsoluteSizeSpan(17, true), 5, 9, Spannable.SPAN_INCLUSIVE_EXCLUSIVE)
    contentText.setSpan(AbsoluteSizeSpan(13, true), 9, contentText.length, Spannable.SPAN_INCLUSIVE_INCLUSIVE)
    content.text = contentText
    
    view.findViewById<TextView>(R.id.cancel).onClick { alertDialog.dismiss() }
    view.findViewById<TextView>(R.id.confirm).onClick { alertDialog.dismiss() }
    alertDialog.show()

进阶实现

项目中用到的新技术稍微多一些，这里稍微做下说明

  • 命令式UI用到了 splitties 视图框架
  • 部分控件用到了 扩展函数

弹框样式

                    typefaceScale = TypefaceScale.MEDIUM_SMALL
                    gravity = gravityCenter
                    textColor = "#F9E6D4".toColorInt()
                    textSize = 14f
                    text = "免费领取"
                })
            })
        })
        add(lParams(width = wrapContent, gravity = gravityCenterHorizontal), imageView {
            imageResource = R.drawable.icon_discount_alert
        })
    }

    /**

     */
    fun setMessage(message: CharSequence) {
        messageView.text = message
        if (message is SpannedString) {
            messageView.movementMethod = LinkMovementMethod.getInstance()
        }
    }

    /**

    fun setNegativeButton(negativeText: CharSequence, listener: OnClickListener?) {
        negativeView.text = negativeText
        negativeView.setOnClick(listener)
    }

    /**
     * 积极按钮
     */
    fun setPositiveButton(positiveText: CharSequence, listener: OnClickListener?) {
        positiveView.text = positiveText
        positiveView.setOnClick(listener)
    }

}

扩展函数

View、TextView （基本UI）
@file:Suppress("NOTHING_TO_INLINE", "unused")

package xx.views

import android.graphics.Bitmap
import android.graphics.drawable.Drawable
import android.view.Gravity

    get() = LayoutInflater.from(context)

var View.backgroundResource: Int
    @Deprecated(NO_GETTER, level = DeprecationLevel.HIDDEN) get() = noGetter
    set(value) {
        setBackgroundResource(value)
    }


inline var View.backgroundColor: Int
    @Deprecated(NO_GETTER, level = DeprecationLevel.HIDDEN) get() = noGetter
    set(@ColorInt colorInt) = setBackgroundColor(colorInt)

inline fun View.onLongClick(consume: Boolean = true, crossinline block: () -> Unit) = setOnLongClickListener { block(); consume }

inline var ImageView.imageResource: Int
    @Deprecated(NO_GETTER, level = DeprecationLevel.HIDDEN) get() = noGetter
    set(@DrawableRes value) = setImageResource(value)

    get() = drawable

    textAlignment = View.TEXT_ALIGNMENT_CENTER
    gravity = Gravity.CENTER
}

    textAlignment = View.TEXT_ALIGNMENT_VIEW_START
    gravity = Gravity.START

    if (intrinsicBounds) {

    setCompoundDrawablesWithIntrinsicBounds(start, top, end, bottom)
}

inline fun TextView.clearCompoundDrawables() = setCompoundDrawables(null, null, null, null)
SpannableStringBuilder 自身（富文本）

根据效果，我仅加入了字体大小的扩展函数

fun SpannableStringBuilder.appendRelativeSize(
    proportion: Float,
    text: CharSequence,
): SpannableStringBuilder = inSpans(RelativeSizeSpan(proportion)) { append(text) }

fun SpannableStringBuilder.appendAbsoluteSize(
    proportion: Int,
    text: CharSequence,
): SpannableStringBuilder = inSpans(AbsoluteSizeSpan(proportion,true)) { append(text) }

项目内较全的 SpannableStringBuilder 扩展函数

inline fun SpannableStringBuilder.linearGradient(
    colors: IntArray,
    orientation: Int = LinearGradientFontSpan.HORIZONTAL,
    builderAction: SpannableStringBuilder.() -> Unit
): SpannableStringBuilder {
    return inSpans(LinearGradientFontSpan(colors, orientation), builderAction = builderAction)
}

inline fun SpannableStringBuilder.clickable(
    listener: View.OnClickListener,
    builderAction: SpannableStringBuilder.() -> Unit
): SpannableStringBuilder {
    return inSpans(ClickableSpan(listener), builderAction = builderAction)
}

//
fun SpannableStringBuilder.appendClickable(
    text: CharSequence,
    listener: View.OnClickListener
): SpannableStringBuilder = inSpans(ClickableSpan(listener)) { append(text) }

fun SpannableStringBuilder.appendColor(
    @ColorInt color: Int,
    text: CharSequence,
): SpannableStringBuilder = inSpans(ForegroundColorSpan(color)) { append(text) }

fun SpannableStringBuilder.appendStrikeThrough(
    text: CharSequence,
): SpannableStringBuilder = inSpans(StrikethroughSpan()) { append(text) }

fun SpannableStringBuilder.appendRelativeSize(
    proportion: Float,
    text: CharSequence,
): SpannableStringBuilder = inSpans(RelativeSizeSpan(proportion)) { append(text) }

fun SpannableStringBuilder.appendAbsoluteSize(
    proportion: Int,
    text: CharSequence,
): SpannableStringBuilder = inSpans(AbsoluteSizeSpan(proportion,true)) { append(text) }
//
fun SpannableStringBuilder.appendMore(
    @ColorInt color: Int? = null,
    text: CharSequence,
    listener: View.OnClickListener? = null,
): SpannableStringBuilder {
    val spans = mutableListOf<Any>()
    color?.also { spans.add(ForegroundColorSpan(color)) }
    listener?.also { spans.add(ClickableSpan(listener)) }
    inSpans(*spans.toTypedArray()) { append(text) }
    return this
}

fun SpannableStringBuilder.appendLabel(
    @ColorInt color: Int? = null,
    text: String,
    listener: View.OnClickListener? = null,
): SpannableStringBuilder {
    val splits = text.replace("</b>", "<b>").split("<b>")
    splits.forEachIndexed { index, s ->
        if (index % 2 == 1) {
            appendMore(color = color, s, listener)
        } else {
            append(s)
        }
    }
    return this
}

ClickableSpan

package xx.spannable

import android.text.TextPaint
import android.view.View
import xx.OnClickWrapListener

class ClickableSpan(val listener: View.OnClickListener) : android.text.style.ClickableSpan() {

    override fun onClick(widget: View) {

    }

    override fun updateDrawState(ds: TextPaint) {

    }
}

OnClickWrapListener

//private var clickTime = 0L

class OnClickWrapListener(val listener: View.OnClickListener) : View.OnClickListener {
    companion object {
        private val clickTime = AtomicLong(0)
    }

    override fun onClick(v: View?) {

            clickTime.set(currentTime)
            listener.onClick(v)
        }

纯净版

            })
            discountAlertDialogUi.setNegativeButton(if (state == 0) "暂不领取" else "暂不续期") {
