Android 实现账号诊断动画效果，逐条检测对应的项目

Dialog中的项目 逐条检测效果：

依赖库：

implementation 'com.github.li-xiaojun:XPopup:2.9.19'
implementation 'com.blankj:utilcodex:1.31.1'
implementation 'com.github.CymChad:BaseRecyclerViewAdapterHelper:3.0.10'

1、item_account_check.xml

2、实体类

data class CheckResultInfo(
        val text: String,
        val value: String,
        var checkState: Int = -1// 检测状态：0 未检测；1检测中；2已检测
)

3、AccountCheckAdapter .kt

open class AccountCheckAdapter : BaseQuickAdapter(R.layout.item_account_check) {

    override fun convert(helper: BaseViewHolder, item: CheckResultInfo) {
        try {
            val tvWord = helper.getView(R.id.tv_title)
            tvWord.text = item.text
            val ivState = helper.getView(R.id.iv_state)
            if (item.checkState < 1) {
                // 未诊断
                ivState.isVisible = false
            } else if (item.checkState == 1) {
                // 正在诊断
                ivState.isVisible = true
                ImageLoader.loadUrl(mContext, R.mipmap.ic_item_checking, ivState)
                tvWord.typeface = Typeface.defaultFromStyle(Typeface.BOLD)
                tvWord.setTextSize(TypedValue.COMPLEX_UNIT_PX, mContext.resources.getDimension(R.dimen.sp_32))
            } else if (item.checkState == 2) {
                // 已诊断
                ivState.isVisible = true
                ImageLoader.loadUrl(mContext, R.mipmap.ic_item_checked, ivState)
                tvWord.typeface = Typeface.DEFAULT_BOLD
                tvWord.setTextSize(TypedValue.COMPLEX_UNIT_PX, mContext.resources.getDimension(R.dimen.sp_28))
            }
        } catch (e: Exception) {
            e.printStackTrace()
        }
    }
}

4、dialog_account_check.xml

5、AccountCheckDialog.kt

/**
 * 账号诊断
 */
class AccountCheckDialog(
        mContext: Context,
        private val dataList: List,
        private val checkedCallback: (() -> Unit)? = null,
) : CenterPopupView(mContext) {
    private lateinit var checkAdapter: AccountCheckAdapter
    private val checkTime = 1500L
    private val MSG_WHAT = 1000

    override fun getImplLayoutId(): Int {
        return R.layout.dialog_account_check
    }

    override fun onCreate() {
        super.onCreate()
        initListener()
        startCheck()
    }

    private fun initListener() {
        val rvList = findViewById(R.id.rv_list)
        val ivClose = findViewById(R.id.iv_close)

        with(rvList) {
            layoutManager = LinearLayoutManager(context)
            checkAdapter = AccountCheckAdapter()
            adapter = checkAdapter
            checkAdapter.setNewData(dataList)
        }
        com.jr.libbase.extension.setOnClickListener(ivClose) {
            when (this) {
                ivClose -> {
                    mHandler.removeCallbacksAndMessages(null)
                    dismiss()
                }
            }
        }
    }

    private fun startCheck() {
        val currentPos = 0
        checkAdapter.data[currentPos].checkState = 1
        checkAdapter.notifyItemChanged(currentPos)
        mHandler.sendMessageDelayed(Message().apply {
            what = MSG_WHAT
            arg1 = currentPos
        }, checkTime)
    }


    private val mHandler = MyHandler(this)

    private class MyHandler(dialog: AccountCheckDialog?) : Handler() {
        //弱引用持有HandlerActivity , GC 回收时会被回收掉
        private val weakReference: WeakReference

        init {
            weakReference = WeakReference(dialog)
        }

        override fun handleMessage(msg: Message) {
            super.handleMessage(msg)
            val mDialog: AccountCheckDialog = weakReference.get() ?: return

            when (msg.what) {
                mDialog.MSG_WHAT -> {
                    try {
                        var position = msg.arg1

                        Log.d("caowj", "dialog position=$position")
                        if (position < mDialog.dataList.size) {
                            mDialog.checkAdapter.data[position].checkState = 2
                            mDialog.checkAdapter.notifyItemChanged(position)
                            position += 1

                            if (position <= mDialog.dataList.size - 1) {
                                mDialog.checkAdapter.data[position].checkState = 1
                                mDialog.checkAdapter.notifyItemChanged(position)

                                sendMessageDelayed(Message().apply {
                                    what = mDialog.MSG_WHAT
                                    arg1 = position
                                }, mDialog.checkTime)
                            }else{
                                mDialog.checkedCallback?.invoke()
                                mDialog.dismiss()
                            }
                        }
                    } catch (e: Exception) {
                        e.printStackTrace()
                    }
                }
            }
        }
    }
}

6、使用Dialog：

    /**
     * 账号诊断Dialog
     */
    private fun showCheckingDialog(list: List) {
        XPopup.Builder(context)
            .isDestroyOnDismiss(true)
            .dismissOnBackPressed(false)
            .dismissOnTouchOutside(false)
            .asCustom(AccountCheckDialog(requireContext(), list, checkedCallback = {
                Log.d("caowj", "账号诊断完成，查看检测报告")
            })).show()
    }
