在popupwindow中使用

例子

public class DownloadPopupWindow extends AbsPopupWindow {
  @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/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() {
    if (Aria.download(this).taskExists(DOWNLOAD_URL)) {
      DownloadTarget target = Aria.download(this).load(DOWNLOAD_URL);
      int p = (int) (target.getCurrentProgress() * 100 / target.getFileSize());
      mPb.setProgress(p);
    }
    Aria.download(this).register();
    DownloadEntity entity = Aria.download(this).getDownloadEntity(DOWNLOAD_URL);
    if (entity != null) {
      mSize.setText(CommonUtil.formatFileSize(entity.getFileSize()));
      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() + "/消消乐.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;
    }
  }

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

  }

  private void setBtState(boolean startEnable) {
    mStart.setEnabled(startEnable);
    mCancel.setEnabled(!startEnable);
    mStop.setEnabled(!startEnable);
  }

  @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("0.0kb/s");
  }

  @Download.onTaskCancel public void onTaskCancel(DownloadTask task) {
    setBtState(true);
    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();
  }
