<?xml version="1.0" encoding="utf-8"?>
<androidx.cardview.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"

3.完整方法

//loading框
@SuppressLint("StaticFieldLeak")
private var loadingDialog: MaterialDialog? = null
private var showTime : Long = 0;
private const val showLoadingTime = 1000;
/**
 * 打开等待框
 */
fun AppCompatActivity.showLoadingExt(message: String = "请求网络中") {
    if (!this.isFinishing) {
        if (loadingDialog == null) {
            loadingDialog = MaterialDialog(this)
                    .cancelable(true)
                    .cancelOnTouchOutside(false)
                    .cornerRadius(12f)
                    .customView(R.layout.layout_custom_progress_dialog_view)
                    .lifecycleOwner(this)
            loadingDialog?.getCustomView()?.run {
                this.findViewById<TextView>(R.id.loading_tips).text = message
//                this.findViewById<ProgressBar>(R.id.progressBar).indeterminateTintList = SettingUtil.getOneColorStateList(this@showLoadingExt)
            }
        }
        showTime = System.currentTimeMillis();
        loadingDialog?.show()
    }
}

/**
 * 打开等待框
 */
fun Fragment.showLoadingExt(message: String = "请求网络中") {
    activity?.let {
        if (!it.isFinishing) {
            if (loadingDialog == null) {
                loadingDialog = MaterialDialog(it)
                    .cancelable(true)
                    .cancelOnTouchOutside(false)
                    .cornerRadius(12f)
                    .customView(R.layout.layout_custom_progress_dialog_view)
                    .lifecycleOwner(this)
                loadingDialog?.getCustomView()?.run {
                    this.findViewById<TextView>(R.id.loading_tips).text = message
//                    this.findViewById<ProgressBar>(R.id.progressBar).indeterminateTintList = SettingUtil.getOneColorStateList(it)
                }
            }
            showTime = System.currentTimeMillis();
            loadingDialog?.show()
        }
    }
}

/**
 * 关闭等待框
 */
fun Activity.dismissLoadingExt() {
    if (System.currentTimeMillis() - showTime < showLoadingTime){
        Timer().schedule(showLoadingTime-(System.currentTimeMillis() - showTime )){
            loadingDialog?.dismiss()
            loadingDialog = null        }
    }else{
        loadingDialog?.dismiss()
        loadingDialog = null
    }
}

/**
 * 关闭等待框
 */
fun Fragment.dismissLoadingExt() {
    if (System.currentTimeMillis() - showTime < showLoadingTime){
        Timer().schedule(showLoadingTime-(System.currentTimeMillis() - showTime )){
            loadingDialog?.dismiss()
            loadingDialog = null        }
    }else{
        loadingDialog?.dismiss()
        loadingDialog = null
    }
}

4.调用方法

展示弹窗

showLoadingExt("加载中...")

隐藏弹窗保证在UI线程调用

dismissLoadingExt()

如果不在UI线程

 runOnUiThread {
            dismissLoadingExt()
        }
