马占柱 人气:2想了解Android实现加载等待展示的相关内容吗,马占柱在本文为您仔细讲解Android加载等待展示的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:Android加载等待展示,Android加载展示,Android加载等待,下面大家一起来学习吧。
package com.zhcs.gis.app.modulecore.core.component.tool; import android.app.Activity; import android.view.LayoutInflater; import android.view.View; import com.zhcs.gis.app.modulecore.R; import java.lang.ref.WeakReference; import androidx.appcompat.app.AlertDialog; public class LoadingDialogUtils_M { private static AlertDialog loadingDialog; private static WeakReference<Activity> reference; private static void init(Activity act) { init(act, -1); } private static void init(Activity activity, int res) { if (loadingDialog == null || reference == null || reference.get() == null || reference.get().isFinishing()) { reference = new WeakReference<>(activity); loadingDialog = new AlertDialog.Builder(reference.get()).create(); if (res > 0) { View view = LayoutInflater.from(activity).inflate(res, null); loadingDialog.setView(view); loadingDialog.getWindow().setBackgroundDrawableResource(android.R.color.transparent); // loadingDialog.setContentView(res); } else { loadingDialog.setMessage("加载中..."); } loadingDialog.setCancelable(false); } } public static void setCancelable(boolean b) { if (loadingDialog == null) return; loadingDialog.setCancelable(b); } /** * 显示等待框 */ public static void show(Activity act) { show(act, false); } public static void show(Activity act, boolean isCancelable) { show(act, R.layout.dialog_loading, isCancelable); } public static void show(Activity activity, int res, boolean isCancelable) { init(activity, res); loadingDialog.show(); setCancelable(isCancelable); } /** * 隐藏等待框 */ public static void dismiss() { if (loadingDialog != null && loadingDialog.isShowing()) { loadingDialog.dismiss(); loadingDialog = null; reference = null; } } }
在使用的时候,在baseactivity里面这样设置:
public void showLoading(boolean show) { if (show) { LoadingDialogUtils_M.show(context, true); } else { LoadingDialogUtils_M.dismiss(); } }
附件:
这是dialog_loading布局文件:
<?xml version="1.0" encoding="utf-8"?> <RelativeLayout 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="match_parent"> <ProgressBar android:id="@+id/progress" android:layout_width="50dp" android:layout_height="50dp" android:layout_centerInParent="true" android:indeterminateDrawable="@drawable/bg_progressbar" /> </RelativeLayout>
这是bg_progressbar配置:
<?xml version="1.0" encoding="utf-8"?> <rotate xmlns:android="http://schemas.android.com/apk/res/android" android:drawable="@mipmap/img_loading" android:fromDegrees="0" android:pivotX="50%" android:pivotY="50%" android:toDegrees="1080" />
最后就是加载的图片img_loading的样式,可以自定义,随便上网找一个就可以,看着好看就行。
最后就可以使用了,挺有用的一个小技巧,加载用的,也可以用其他的方式实现,只要效果一样就行。
