实现效果：
代码开始：
res/layout自定义的布局dialog_loading.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/dialog_loading_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:orientation="vertical">
<LinearLayout
android:layout_width="140dp"
android:layout_height="100dp"
android:background="@android:color/darker_gray"
android:gravity="center"
android:orientation="vertical"
android:paddingLeft="21dp"
android:paddingTop="10dp"
android:paddingRight="21dp"
android:paddingBottom="10dp">
<ProgressBar
android:id="@+id/progressBar1"
android:layout_width="35dp"
android:layout_height="35dp"
android:layout_gravity="center_horizontal"
android:indeterminateBehavior="repeat"
android:indeterminateDrawable="@drawable/dialog_loading"
android:indeterminateOnly="true" />
<TextView
android:id="@+id/tipTextView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="15dp"
android:text="加载中..."
android:textColor="@android:color/white"
android:textSize="15sp" />
</LinearLayout>
</LinearLayout>
ProgressBar引用的drawable下的动画资源dialog_loading.xml
<?xml version="1.0" encoding="utf-8"?>
<animated-rotate xmlns:android="http://schemas.android.com/apk/res/android"
android:drawable="@drawable/loading_bg"
android:pivotX="50%"
android:pivotY="50%" />阿里巴巴矢量图标下载：https://www.iconfont.cn/

package com.example;

import com.example.R;
public class LoadingDialog extends Dialog {

public LoadingDialog create() {
LayoutInflater inflater = LayoutInflater.from(context);
View view = inflater.inflate(R.layout.dialog_loading, null);
LoadingDialog loadingDailog = new LoadingDialog(context, R.style.CustomDialog);
TextView msgText = (TextView) view.findViewById(R.id.tipTextView);
if (isShowMessage) {
msgText.setText(message);
} else {
msgText.setVisibility(View.GONE);
}
loadingDailog.setContentView(view);
loadingDailog.setCancelable(isCancelable);
loadingDailog.setCanceledOnTouchOutside(isCancelOutside);
return loadingDailog;
}
}
}
引用样式
<!-- 自定义dialog的样式 -->
<style name="CustomDialog">
<item name="android:windowFrame">@null</item><!--边框-->
<item name="android:windowIsFloating">true</item><!--是否浮现在activity之上-->
<item name="android:windowIsTranslucent">false</item><!--半透明-->
<item name="android:windowNoTitle">true</item><!--无标题-->
<item name="android:windowBackground">@android:color/transparent</item><!--背景透明-->
<item name="android:backgroundDimEnabled">false</item><!--模糊-->
<item name="android:backgroundDimAmount">0.6</item>
</style>
使用
//加载弹窗
LoadingDialog.Builder loadBuilder = new LoadingDialog.Builder(this)
.setMessage("加载中...")
.setCancelable(true)//返回键是否可点击
.setCancelOutside(false);//窗体外是否可点击
dialog = loadBuilder.create();
dialog.show();//显示弹窗
dialog.dismiss();//数据加载完成取消弹窗
