很酷的Android下載進度條：DownloadProgressBar

下載

repositories {
    maven {
        url "https://jitpack.io"
    }
}

dependencies {
    compile 'com.github.panwrona:DownloadProgressBar:1.0'
}

用法

首先需要區別的是兩種結果：成功和失敗。要播放成功動畫，調用下面的一行代碼：

DownloadProgressBar downloadProgressBar = (DownloadProgressBar)findViewById(R.id.download_progress_view);
downloadProgressBar.playToSuccess();

如果想播放錯誤動畫，調用：

DownloadProgressBar downloadProgressBar = (DownloadProgressBar)findViewById(R.id.download_progress_view);
downloadProgressBar.playToError();

同時我還添加了常用事件的listener：whole animation start, whole animation end, progress update, animation success, animation error。要實現他們，如下：

downloadProgressBar.setOnProgressUpdateListener(new DownloadProgressBar.OnProgressUpdateListener() {
            @Override
            public void onProgressUpdate(float currentPlayTime) {
                // Here we are setting % value on our text view.
                successTextView.setText(Math.round(currentPlayTime / 3.6) + " %");
            }

            @Override
            public void onAnimationStarted() {
                // Here we are disabling our view because of possible interactions while animating.
                downloadProgressBar.setEnabled(false);
            }

            @Override
            public void onAnimationEnded() {
                successTextView.setText("Click to download");
                downloadProgressBar.setEnabled(true);
            }

            @Override
            public void onAnimationSuccess() {
                successTextView.setText("Downloaded!");
            }

            @Override
            public void onAnimationError() {

            }
        });
