Question

Answer 1

passer l'adaptateur une référence à l'activité . Puis fournissez une méthode dans l'activité que l'adaptateur peut appeler.

adaptateur:

private MyActivity activity; 

public void setActivity(MyActivity activity) { 
    this.activity = activity; 
} 

En activité:

// create adapter 
adapter.setActvity(this); 

adaptateur (lorsque vous voulez transmettre les paramètres à l'activité):

activity.setHashMap(mymap); 

Answer 2

Mon CustomAdapter Classe: :
classe SearchResultAdapter étend ArrayAdapter {

Context context; 
    int layoutResourceId; 
    private ArrayList<SearchResultModel> results; 

    public SearchResultAdapter(Context context, int layoutResourceId, ArrayList<SearchResultModel> results) { 
     super(context, layoutResourceId, results); 
     this.layoutResourceId = layoutResourceId; 
     this.context = context; 
     this.results = results; 
    } 

    @Override 
    public View getView(int position, View convertView, ViewGroup parent) 
    { 
     View row = convertView; 
     SearchResultHolder holder=null; 
     if(row == null) 
     { 
      LayoutInflater vi = ((Activity)context).getLayoutInflater(); 
      row = vi.inflate(R.layout.listitemrow, null); 
      holder = new SearchResultHolder(); 
      holder.jobdetails = (TextView)row.findViewById(R.id.jobdetails); 
      row.setTag(holder); 
     } 
     else 
     { 
      holder = (SearchResultHolder)row.getTag(); 
     } 
     SearchResultModel model = results.get(position); 

     if (model != null) 
     { 
      row.setId(Integer.parseInt(model.getjob_id())); 
      String result= 
        "<font color=#5D2E8C>"+model.getjob_title()+"</font><br>" + 
        "<font color=#737373>"+model.getpost_date()+"</font><br>"+model.getuser_name()+"<br>" + 
        "<font color=#3C5A98>"+model.getsalary()+" Rs (Per Annum)</font><br>"+ 
        "<font color=#97AB40>"+model.getjob_location()+"," + 
        " "+model.getjob_exp_min()+"-"+model.getjob_exp_max()+" year"; 
      holder.jobdetails.setText(Html.fromHtml(result)); 

     } 
     return row; 
    } 

    class SearchResultHolder 
    { 
     TextView jobdetails; 
    } 
} 

Mon ListView dans la principale méthode qui utiliserait le dessus ArrayAdapter.

SearchResultAdapter adapter; 
ListView lv; 
adapter=new SearchResultAdapter(this, R.layout.listitemrow, model); 
//Here model is the ArrayList<SearchResultModel> 
lv=getListView(); 
lv.setAdapter(adapter); 
lv.setOnItemClickListener(new OnItemClickListener() 
{ 
    public void onItemClick(AdapterView<?> arg0, View v,int arg2, long arg3) 
    { 
    } 
}
