如何使ProgressBar处于圆形并处于确定模式? [英] How to have a ProgressBar circular and in determinate mode?

问题描述

我必须在设备上下载一些图像和视频，我想通过在确定的模式下将圆形的ProgressBar叠加在其上来跟踪进度.

I have to download some images and videos on the device and I like to track the progress by having a circular ProgressBar in determinate mode in overlay to them.

问题在于，无论如何，ProgressBar仍不确定.

The problem is that, no matter what, the ProgressBar is still indeterminate.

是否有办法使它呈圆形并处于确定模式?

Is there a way to have it circular and in determinate mode?

布局

<ProgressBar
                android:layout_width="40dp"
                android:layout_height="40dp"
                android:progressTint="@color/colorPrimary"
                android:indeterminate="false"
                android:max="100"
                android:layout_gravity="center"
                android:id="@+id/message_media_preview_progress"
                android:visibility="gone"
                />

代码

final ProgressBar progressBar = (ProgressBar) mView.findViewById(R.id.message_media_preview_progress);
progressBar.setVisibility(View.VISIBLE);
progressBar.setProgress(0);
storageController.downloadMedia(context, message.getVideoFile(),
        new ProgressListener<Integer>() {
            @Override
            public void onResult(Integer result) {
                progressBar.setProgress(result);
            }
        },
        new ResultListener<Boolean>() {
            @Override
            public void onResult(Boolean result) {
                if(result) {
                    progressBar.setVisibility(View.GONE);
                    setMediaClickListener(message);
                }else{
                    Toast.makeText(context,"Error downloading file",Toast.LENGTH_SHORT).show();
                }
            }
        });

推荐答案

不幸的是，这无法通过现有的Android ProgressBar实现.查找类似以下的外部库:

Unfortunately, this is not possible with stock Android ProgressBar. Look for external libraries like:
