xUtils3的下載方法很方便提供了下載進度，首先，我們需要用程式碼註冊一個廣播接受者，用於接收下載進度，然後在xUtils3的下載方法裡傳送進度廣播即可。

廣播接收者：

private ProgressReceiver progressReceiver;
    /**
     * 用於通知遊戲下載進度的廣播接收者
     */
    private class ProgressReceiver extends BroadcastReceiver {

        @Override
        public void onReceive(Context context, Intent intent) {
            /*if (TextUtils.equals(intent.getAction(), "progress")) {

            }*/
 

            // 辨別正在下載的遊戲是不是當前介面展示的遊戲
            String downloadingGameId = intent.getStringExtra("gameId");
            if (TextUtils.equals(gameId, downloadingGameId)) {
                if (mpb_download_progress.getVisibility() != View.VISIBLE) {
                    mpb_download_progress.setVisibility(View.VISIBLE);
                }

                // 進度
 

                int progress = intent.getIntExtra("progress", 0);
                mpb_download_progress.setProgress(progress);

                if (progress == 100) {
                    // 下載完成
                    mpb_download_progress.setVisibility(View.GONE);
                    view_step_to_two.setVisibility(View.VISIBLE);
                    btn_open_game.setEnabled(true
 
);
                    btn_open_game.setTextColor(getResources().getColor(R.color.white));

                    //下載完成
                    onDownloadFinished();
                }
            }
        }
    }

註冊：

progressReceiver = new ProgressReceiver();
        IntentFilter progressFilter = new IntentFilter("progress");
        registerReceiver(progressReceiver, progressFilter);

銷燬：

if (progressReceiver != null) {
            unregisterReceiver(progressReceiver);
        }

下載方法：

private final Executor executor = new PriorityExecutor(2, true);
    /**
     * 下載遊戲，這個方法在Activity銷燬之後仍會繼續執行
     */
    private void downloadGame() {
        if (TextUtils.isEmpty(gameUrl)) {
            ToastUtils.showShort(mActivity, "遊戲下載地址為空");
            return;
        }

        if (!TextUtils.isEmpty(gameLocalPath)) {
            org.xutils.http.RequestParams params = new org.xutils.http.RequestParams(gameUrl);
            params.setAutoRename(true);
            params.setAutoResume(true);
            params.setAutoResume(true);
            params.setAutoRename(false);
            params.setSaveFilePath(gameLocalPath);
            params.setExecutor(executor);
            params.setCancelFast(true);

            x.http().get(params, new Callback.ProgressCallback<File>() {

                @Override
                public void onWaiting() {

                }

                @Override
                public void onStarted() {

                }

                @Override
                public void onLoading(long total, long current, boolean isDownloading) {
                    // 下載進度
                    Intent intent = new Intent("progress");
                    intent.putExtra("progress", (int)(current*100/total));
                    intent.putExtra("gameId", gameId);
                    sendBroadcast(intent);
                }

                @Override
                public void onSuccess(File result) {

                }

                @Override
                public void onError(Throwable ex, boolean isOnCallback) {

                }

                @Override
                public void onCancelled(CancelledException cex) {

                }

                @Override
                public void onFinished() {

                }
            });
        }
    }
