Android Dialog封装

先看效果

具体使用

 CommonDialogBuilder(this, R.style.CommonDialogStyleTest).withType(CommonDialogBuilder.NOTITLE_ONLY)
            .withTitle("标题")
            .withMessage("消息")
            .withNegative { view, dialog ->
                toast("点击了取消，没有数据")
            }
            .withNegative { view, dialog, data ->
 				toast("点击了取消，有数据")
            }
            .withPositive { view, dialog ->
                 toast("点击了确定，没有数据")
            }
            .withPositive { view, dialog, data ->
                  toast("点击了确定，有数据")
            }
            .withAnimStyle(R.style.dialogAnimation)  //设置动画
            .show()

部分代码

Dialog的封装，主要是项目中会有多个自定义Dialog，不需要每个自定义Dialog都需要重写，只需要继承好自己封装好的BaseDialog就可以了。

这里提供了一个实现好的封装Dialog也就是CommonDialog，大家可以直接使用。
如果需要自定义Dialog，继承BaseDialogBuilder和BaseDialog。这里具体的实现参照CommonDialog和CommonDialogBuilder即可。

下面贴出封装的部分基类代码：全部代码请移步：GitHub

BaseDialogBuilder类

abstract class BaseDialogBuilder(var context: Context, var style: Int) {

    //初始化 Builder
    abstract var dialogBuilder: B

    //初始化Dialog
    abstract fun build(): D

    open var dialog: D? = null

    //标题
    open var title: String? = null
    //消息
    open var message: String? = null
    //dialog宽度
    open var width = WindowManager.LayoutParams.MATCH_PARENT
    //dialog高度
    open var height = WindowManager.LayoutParams.WRAP_CONTENT
    open var gravity = Gravity.CENTER

    open var isCancelable = true//点击空白区域是否消失。默认消失

    open var animStyle = 0//进入退出动画

    open var dimAmount = 1.1f //背景昏暗度

    //positive按钮。一般是右边的确定按钮。这个用户自定义。
    open var positiveStr: String? = null
    open var onPositiveDialogClickedListener: OnDialogClickedListener? = null

    //negative按钮。一般是左边的取消按钮。这个用户自定义。
    open var negativeStr: String? = null
    open var onNegativeDialogClickedListener: OnDialogClickedListener? = null

    open fun show(): D {
        if (dialog == null) {
            dialog = build()
        }
        dialog!!.show(this)
