我想知道如何使用stdout编写脚本,比如命令行,例如'更多' less',' man'似乎他们在另一层bash中显示了他们的结果。 如何在python中编写带有这样输出的程序?

您可以使用pydoc.pager。它在标准库中。
public class Home extends AppCompatActivity {
/* Views */
ProgressDialog progDialog;
/* Variables */
List<ParseObject> eventsArray = null;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.home);
// ProgressDialog
progDialog = new ProgressDialog(this);
progDialog.setTitle(R.string.app_name);
progDialog.setMessage("Loading...");
progDialog.setIndeterminate(false);
progDialog.show();
// Call query
queryEvents();
}
// MARK: - QUERY EVENTS
public void queryEvents() {
ParseQuery<ParseObject> query = ParseQuery.getQuery(Configs.EVENTS_CLASS_NAME);
query.whereEqualTo(Configs.EVENTS_IS_PENDING, false);
query.orderByAscending(Configs.EVENTS_END_DATE);
query.findInBackground(new FindCallback<ParseObject>() {
public void done(List<ParseObject> objects, ParseException error) {
if (error == null) {
eventsArray = objects;
progDialog.dismiss();
// CUSTOM GRID ADAPTER
class GridAdapter extends BaseAdapter {
private List<ParseObject> objects;
private Context context;
public GridAdapter(FindCallback<ParseObject> context, List<ParseObject> objects) {
super();
this.context = (Context) context;
eventsArray = objects;
}
// CONFIGURE CELL
@Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) context .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View gridView;
if (convertView == null) {
gridView = new View(context);
// Get layout from event_cell.xml
gridView = inflater.inflate(R.layout.event_cell, null);
// Get title
TextView titleTxt = (TextView) gridView.findViewById(R.id.titleTxt);
if (eventsArray.get(position).getString(Configs.EVENTS_TITLE) != null) {
titleTxt.setText(eventsArray.get(position).getString(Configs.EVENTS_TITLE).toString());
} else { titleTxt.setText("N/A"); }
} else { gridView = (View) convertView; }
return gridView;
}
@Override
public int getCount() {
if (eventsArray != null) {
return eventsArray.size();
}
return 0;
}
@Override
public Object getItem(int position) {
return eventsArray.get(position);
}
@Override
public long getItemId(int position) {
return 0;
}
}
// Init GridView and set its adapter
GridView eventsGrid = (GridView) findViewById(R.id.eventsGridView);
eventsGrid.setAdapter(new GridAdapter(this, eventsArray));
eventsGrid.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
Toast.makeText(getApplicationContext(), ((TextView) v.findViewById(R.id.titleTxt)).getText(), Toast.LENGTH_SHORT).show();
}
});
// Error in query
} else {
Toast.makeText(getApplicationContext(), error.getMessage().toString(), Toast.LENGTH_LONG).show();
}
}
});
}
} //@end
