在popupwindow中使用

例子

public class DownloadPopupWindow extends AbsPopupWindow implements View.OnClickListener {
  private HorizontalProgressBarWithNumber mPb;
  private Button mStart;
  private Button mCancel;
  private TextView mSize;
  private TextView mSpeed;
  private long mTaskId = -1;

  private static final String DOWNLOAD_URL =
      "http://static.gaoshouyou.com/d/25/57/2e25bd9d4557ba31e9beebacfaf9e804.apk";

  public DownloadPopupWindow(Context context) {
    super(context, new ColorDrawable(Color.WHITE));
    initWidget();
  }

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

  private void initWidget() {
    mPb = mView.findViewById(R.id.progressBar);
    mStart = mView.findViewById(R.id.start);
    mCancel = mView.findViewById(R.id.cancel);
    mSize = mView.findViewById(R.id.size);
    mSpeed = mView.findViewById(R.id.speed);

    mStart.setOnClickListener(this);
    mCancel.setOnClickListener(this);

    DownloadEntity entity = Aria.download(this).getFirstDownloadEntity(DOWNLOAD_URL);
    if (entity != null) {
      mPb.setProgress(entity.getPercent());
      mSize.setText(CommonUtil.formatFileSize(entity.getFileSize()));
      if (entity.getState() == IEntity.STATE_RUNNING) {
        mStart.setText(getContext().getString(R.string.stop));
      } else {
        mStart.setText(getContext().getString(R.string.resume));
      }
      mTaskId = entity.getId();
    } else {
      mStart.setText(getContext().getString(R.string.start));
    }
    Aria.download(this).register();
  }

  @Override
  public void onClick(View view) {
    switch (view.getId()) {
      case R.id.start:
        if (mTaskId != -1) {
          Aria.download(this)
              .load(DOWNLOAD_URL)
              .setFilePath(Environment.getExternalStorageDirectory().getPath() + "/消消乐.apk")
              .create();
          mStart.setText(getContext().getString(R.string.stop));
          break;
        }
        if (Aria.download(this).load(mTaskId).isRunning()) {
          Aria.download(this).load(mTaskId).stop();
          mStart.setText(getContext().getString(R.string.resume));
        } else {
          Aria.download(this).load(mTaskId).resume();
          mStart.setText(getContext().getString(R.string.stop));
        }
        break;

      case R.id.cancel:

        Aria.download(this).load(mTaskId).cancel();
        mStart.setText(getContext().getResources().getString(R.string.start));
        mTaskId = -1;
        break;
    }
  }

  @Override protected void dataCallback(int result, Object obj) {

  }

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

  @Download.onTaskStop public void onTaskStop(DownloadTask task) {
    mSpeed.setText("0.0kb/s");
    mStart.setText(getContext().getString(R.string.resume));
  }

  @Download.onTaskCancel public void onTaskCancel(DownloadTask task) {
    mPb.setProgress(0);
    mSpeed.setText("0.0kb/s");
  }

  @Download.onTaskRunning public void onTaskRunning(DownloadTask task) {
    long current = task.getCurrentProgress();
    long len = task.getFileSize();
    if (len == 0) {
      mPb.setProgress(0);
    } else {
      mPb.setProgress((int) ((current * 100) / len));
    }
    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())或Aria.download(getContext())
  请使用：
  Aria.download(this)或Aria.download(this)

• 注册或移除监听注意事项

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

      }
    });

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

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