Question

我有2个微调器，每个都包含文本视图和ProgressBar。当我在第二个sprinner中选择元素时，应该看到ProgressBar和服务器的请求应该获取一些数据并填充一个微调器，在填充微调器之后，progressBar应该是不可分割的。现在，在第二个微调器上从第一个微调器中选择一个元素后，将显示ProgressBar（发出请求），只有当从第二个微调器中选择了项目时才会隐藏ProgressBar。我不知道我应该在代码中更改什么，请帮忙。这是我的代码：

微调：

@Override
public View getView(int position, View convertView, ViewGroup parent) {


    View row = mInflater.inflate(...);
    TextView itemView = (TextView) row.findViewById(...);
    mProgressBar = (ProgressBar) row.findViewById(...);
    //mProgressBar.setVisibility(View.INVISIBLE);
    T item = getItem(position);
    String itemLabel = null;
        itemLabel = mContext.getString(R.string.dialog_filters_item, item.getName());

    }
    itemView.setText(itemLabel);
    return row;
}

@Override
public void setProgressBarVisibility(final boolean visibility) {
    if (mProgressBar != null) {
        if (visibility) {
            mProgressBar.setVisibility(View.VISIBLE);
        } else {
            mProgressBar.setVisibility(View.INVISIBLE);
        }


        Log.v(TAG, "changed visibility on spinner " + visibility);
    }


}

带有微调器的碎片：

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {



    ....        //spinner1 && spniner2 methods run on UI Threads
    spinner1SetProgressBarVisibility(true);
    spinner2SetProgressBarVisibility(false);        //request to server
    mHost.populateSpinner1();       ....
    return v;
}


private void populateSpinner1Spinner(List<Data> dataServerItems) {
    Data dataAll = new Data();
    dataAll.setDepName(...);
    dataAll.setDepNumber(...);
    mDataItems.clear();
    mDataItems.add(dataAll);
    if (dataServerItems != null) {
        mDataItems.addAll(dataServerItems);
    }
    spinner1SetProgressBarVisibility(false);
    spinner2SetProgressBarVisibility(false);


    mSpinner1DataAdapter.notifyDataSetChanged();


}
 private void populateSectionsSpinner(List<Data2> dataServerItems) {
    Data2 dataAll = new Data2();
    dataAll.setSectionName(getString(...));
    dataAll.setSectionNumber(...);
    mData2Items.clear();
    mData2Items.add(0, dataAll);
    if (dataServerItems != null) {
        mSectionItems.addAll(dataServerItems);
    spinner1SetProgressBarVisibility(false);
    spinner2SetProgressBarVisibility(false);
    mSpinner2DataAdapter.notifyDataSetChanged();

}


@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
    Log.v(TAG, "onItemSelected, position=" + position);
    switch (parent.getId()) {
        case R.id.spinner1:
            spinner1SetProgressBarVisibility(false);
              mHost.getData2();
            spinner2SetProgressBarVisibility(true);
            break;
        case R.id.spinner2:
                ...
                break;

            }

}

@Override
public void onNothingSelected(AdapterView<?> parent) {
    // Not used
}

@Override
public void onDataUpdate(List<Data> dataServerItems) {
   populateSpinner1Spinner(List<Data> dataServerItems);

}
@Override
public void onData2Update(List<Data2> dataServerItems) {
     populateSpinner2Spinner(List<Data> dataServerItems);

}    private void spinner1SetProgressBarVisibility(final boolean isVisible) {
    getActivity().runOnUiThread(new Runnable() {
        @Override
        public void run() {
            mSpinner1DataAdapter.setProgressBarVisibility(isVisible);
        }
    });
}

private void spinner2SetProgressBarVisibility(final boolean isVisible) {
    getActivity().runOnUiThread(new Runnable() {
        @Override
        public void run() {
            mSpinner2DataAdapter.setProgressBarVisibility(isVisible);


        }
    });
} }

问题是由CustomAdapter引起的。在进度条的默认可见性设置为false
