在Dialog或DialogFragment中使用

例子


public class DownloadDialog extends AbsDialog {
  @Bind(R.id.progressBar) HorizontalProgressBarWithNumber mPb;
  @Bind(R.id.start) Button mStart;
  @Bind(R.id.stop) Button mStop;
  @Bind(R.id.cancel) Button mCancel;
  @Bind(R.id.size) TextView mSize;
  @Bind(R.id.speed) TextView mSpeed;

  private static final String DOWNLOAD_URL =
      "http://static.gaoshouyou.com/d/4b/d7/e04b308d9cd7f0ad4cac18d1a514544c.apk";

  public DownloadDialog(Context context) {
    super(context);
    init();
  }

  @Override protected int setLayoutId() {
    return R.layout.dialog_download;
  }

  private void init() {
    Aria.download(this).register();
    DownloadEntity entity = Aria.download(this).getDownloadEntity(DOWNLOAD_URL);
    if (entity != null) {
      mSize.setText(CommonUtil.formatFileSize(entity.getFileSize()));
      int p = (int) (entity.getCurrentProgress() * 100 / entity.getFileSize());
      mPb.setProgress(p);
      int state = entity.getState();
      setBtState(state != DownloadEntity.STATE_RUNNING);
    } else {
      setBtState(true);
    }
  }

  @OnClick({ R.id.start, R.id.stop, R.id.cancel }) public void onClick(View view) {
    switch (view.getId()) {
      case R.id.start:
        Aria.download(this)
            .load(DOWNLOAD_URL)
            .setFilePath(Environment.getExternalStorageDirectory().getPath() + "/飞机大战.apk")
            .start();
        break;
      case R.id.stop:
        Aria.download(this).load(DOWNLOAD_URL).stop();
        break;
      case R.id.cancel:
        Aria.download(this).load(DOWNLOAD_URL).cancel();
        break;
    }
  }

  @Download.onTaskPre public void onTaskPre(DownloadTask task) {
    mSize.setText(CommonUtil.formatFileSize(task.getFileSize()));
    setBtState(false);
  }

  @Download.onTaskStop public void onTaskStop(DownloadTask task) {
    setBtState(true);
    mSpeed.setText(task.getConvertSpeed());
  }

  @Download.onTaskCancel public void onTaskCancel(DownloadTask task) {
    setBtState(true);
    mPb.setProgress(0);
    mSpeed.setText(task.getConvertSpeed());
  }

  @Download.onTaskRunning public void onTaskRunning(DownloadTask task) {
    if (task.getKey().equals(DOWNLOAD_URL)) {
      mPb.setProgress(task.getPercent());
      mSpeed.setText(task.getConvertSpeed());
    }
  }
}

注意事项

  • 初始化操作注意事项 从3.4.3版本开始,请不要使用Aria.download(getContext())Aria.download(getContext())
    请使用:
    Aria.download(this)Aria.download(this)

  • 注册或移除监听注意事项

dialog.setOnDismissListener(new DialogInterface.OnDismissListener() {
          @Override public void onDismiss(DialogInterface dialog) {

          }
        });

 dialog.setOnCancelListener(new DialogInterface.OnCancelListener() {
          @Override public void onCancel(DialogInterface dialog) {

          }
        });

如上,如果你已经对Dialog对象设置了OnDismissListenerOnCancelListener事件,那么Aria将无法跟踪Dialog的生命周期;
这时你需要在Dialog的Dismiss手动取消Aria的注册

  @Override public void dismiss() {
    super.dismiss();
    Aria.download(this).unRegister();
  }
