- First Conver your Gif image to png Slice image sequence.
Declare Your Progress bar as Image view.
<ImageView android:id="@+id/main_progress" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center" android:visibility="visible" />Create .xml file in drawable folder using your .png sequence image those are generated from gif.
<?xml version="1.0" encoding="utf-8"?> <animation-list xmlns:android="http://schemas.android.com/apk/res/android" android:oneshot="false"> <item android:drawable="@mipmap/wblod_0" android:duration="40" /> <item android:drawable="@mipmap/wblod_1" android:duration="40" /> <item android:drawable="@mipmap/wblod_2" android:duration="40" /> <item android:drawable="@mipmap/wblod_3" android:duration="40" /> <item android:drawable="@mipmap/wblod_4" android:duration="40" /> <item android:drawable="@mipmap/wblod_5" android:duration="40" /> <item android:drawable="@mipmap/wblod_6" android:duration="40" /> <item android:drawable="@mipmap/wblod_7" android:duration="40" /> <item android:drawable="@mipmap/wblod_8" android:duration="40" /> <item android:drawable="@mipmap/wblod_9" android:duration="40" /> <item android:drawable="@mipmap/wblod_10" android:duration="40" /> <item android:drawable="@mipmap/wblod_11" android:duration="40" /> </animation-list>In Main Activity set the code like,
private AnimationDrawable animationDrawable; private ImageView mProgressBar; mProgressBar.setBackgroundResource(R.drawable.loading_web_animation); animationDrawable = (AnimationDrawable)mProgressBar.getBackground(); mProgressBar.setVisibility(View.VISIBLE); animationDrawable.start(); mProgressBar.setVisibility(View.GONE); animationDrawable.stop();`
- 首先将您的 Gif 图像转换为 png 切片图像序列。
将您的进度条声明为图像视图。
<ImageView android:id="@+id/main_progress" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center" android:visibility="visible" />使用从 gif 生成的 .png 序列图像在 drawable 文件夹中创建 .xml 文件。
<?xml version="1.0" encoding="utf-8"?> <animation-list xmlns:android="http://schemas.android.com/apk/res/android" android:oneshot="false"> <item android:drawable="@mipmap/wblod_0" android:duration="40" /> <item android:drawable="@mipmap/wblod_1" android:duration="40" /> <item android:drawable="@mipmap/wblod_2" android:duration="40" /> <item android:drawable="@mipmap/wblod_3" android:duration="40" /> <item android:drawable="@mipmap/wblod_4" android:duration="40" /> <item android:drawable="@mipmap/wblod_5" android:duration="40" /> <item android:drawable="@mipmap/wblod_6" android:duration="40" /> <item android:drawable="@mipmap/wblod_7" android:duration="40" /> <item android:drawable="@mipmap/wblod_8" android:duration="40" /> <item android:drawable="@mipmap/wblod_9" android:duration="40" /> <item android:drawable="@mipmap/wblod_10" android:duration="40" /> <item android:drawable="@mipmap/wblod_11" android:duration="40" /> </animation-list>在 Main Activity 中设置如下代码，
private AnimationDrawable animationDrawable; private ImageView mProgressBar; mProgressBar.setBackgroundResource(R.drawable.loading_web_animation); animationDrawable = (AnimationDrawable)mProgressBar.getBackground(); mProgressBar.setVisibility(View.VISIBLE); animationDrawable.start(); mProgressBar.setVisibility(View.GONE); animationDrawable.stop();`

In Java File login to show Timer. here I used 10 second timer.
在 Java 文件登录以显示计时器。在这里我使用了 10 秒计时器。
private void progressTimer() {
handler = new Handler();
if (maxCount >= 0) {
handler.postDelayed(new Runnable() {
@Override
public void run() {
/*
Logic to set Time inside Progressbar
*/
mCircularProgressCounter.setText(maxCount+"");
maxCount = maxCount - 1;
pickupTimer();
}
}, 1000);
}
}

Put your gif image in /res/raw folder
将您的 gif 图像放在 /res/raw 文件夹中
In your class declare mProgressDialog
在你的班级中声明 mProgressDialog
TransparentProgressDialog mProgressDialog;
then use following code to show progress dialog
然后使用以下代码显示进度对话框
if (mProgressDialog == null)
mProgressDialog = new TransparentProgressDialog(this);
if (mProgressDialog.isShowing())
mProgressDialog.dismiss();
mProgressDialog.setTitle(getResources().getString(R.string.title_progress_dialog));
mProgressDialog.setCancelable(false);
mProgressDialog.show();
Create a class TransparentProgressDialog where .gif can be loaded using Glide library.
创建一个 TransparentProgressDialog 类，其中 .gif 可以使用 Glide 库加载。
public class TransparentProgressDialog extends Dialog {
private ImageView iv;
public TransparentProgressDialog(Context context) {
super(context, R.style.TransparentProgressDialog);
WindowManager.LayoutParams wlmp = getWindow().getAttributes();
wlmp.gravity = Gravity.CENTER_HORIZONTAL;
getWindow().setAttributes(wlmp);
setTitle(null);
setCancelable(false);
setOnCancelListener(null);
LinearLayout layout = new LinearLayout(context);
layout.setOrientation(LinearLayout.VERTICAL);
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
iv = new ImageView(context);
GlideDrawableImageViewTarget imageViewTarget = new GlideDrawableImageViewTarget(iv);
Glide.with(context).load(R.raw.gif_loader).into(imageViewTarget);
layout.addView(iv, params);
addContentView(layout, params);
}
@Override
public void show() {
super.show();
}
}
}

I solved it before on this post easily: Custom progress bar with GIF (animated GIF) Use an ImageView that shows an Animated GIF and when need to show waiting make it visible and when works all will be done, make it Gone!
我之前在这篇文章中轻松解决了这个问题： 带有 GIF（动画 GIF）的自定义进度条 使用显示动画 GIF 的 ImageView，当需要显示等待时让它可见，当所有工作都完成时，让它消失！

My solution is to use an Animated icon.
我的解决方案是使用动画图标。
1°) Create an XML "animated" in Drawable :
1°) 在 Drawable 中创建一个 XML“动画”：
<?xml version="1.0" encoding="utf-8"?>
<animation-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/micro_1" android:duration="200" />
<item android:drawable="@drawable/micro_2" android:duration="200" />
<item android:drawable="@drawable/micro_3" android:duration="200" />
<item android:drawable="@drawable/micro_4" android:duration="200" />
<item android:drawable="@drawable/micro_3" android:duration="200" />
<item android:drawable="@drawable/micro_2" android:duration="200" />
</animation-list>
2°) Put an imageview in your layout
2°) 在你的布局中放置一个图像视图
3°) Put the following code in your activity :
3°) 将以下代码放入您的活动中：
import androidx.appcompat.app.AppCompatActivity;
import android.app.ProgressDialog;
import android.graphics.drawable.AnimationDrawable;
import android.os.Bundle;

import android.view.View;
import android.widget.ImageView;
public class MainActivity extends AppCompatActivity {
ProgressDialog progressBar;
private int progressBarStatus = 0;
private Handler progressBarHandler = new Handler();
private ImageView micButton;
//-- for testing progress bar
private long fileSize = 0;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//-- declare animation
final AnimationDrawable[] rocketAnimation = new AnimationDrawable[1];
final ImageView micButton = findViewById(R.id.mic_button);
micButton.setBackgroundResource(R.drawable.micro_1);
//-- button listener
micButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
//-- init button with animation
micButton.setBackgroundResource(R.drawable.mic_image);
rocketAnimation[0] = (AnimationDrawable) micButton.getBackground();
startprogress(rocketAnimation[0]);
}
});
}
public void startprogress(final AnimationDrawable rocketAnimation) {
rocketAnimation.start();
progressBar = new ProgressDialog(MainActivity.this);
//--reset filesize for demo
fileSize = 0;
//-- thread for demo
new Thread(new Runnable() {
public void run() {
while (progressBarStatus < 100) {
// process some tasks
progressBarStatus = doSomeTasks();
// your computer is too fast, sleep 1 second
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
// Update the progress bar
progressBarHandler.post(new Runnable() {
public void run() {
progressBar.setProgress(progressBarStatus);
}
});
}
// ok, file is downloaded,
if (progressBarStatus >= 100) {
// sleep 2 seconds, so that you can see the 100%
try {
Thread.sleep(2000);
} catch (InterruptedException e) {
e.printStackTrace();
}
// close the progress bar dialog
progressBar.dismiss();
if(rocketAnimation.isRunning()){
rocketAnimation.stop();
}
}
}
}).start();
}
// file download simulator... a really simple
public int doSomeTasks() {
while (fileSize <= 1000000) { //1000000
fileSize++;
if (fileSize == 100000) {
return 10;
} else if (fileSize == 200000) {
return 20;
