Android 在收到服务器的响应后完成活动

我希望在从另一个java类中的服务器收到完整响应时完成该活动

Category.java

这是主要活动

public void onListItemClick(ListView parent, View v, int position, long id)
    {
        // Get the selected category id & name.
        String catId = "";
        String catName = "";
        LinearLayout ll = (LinearLayout)findViewById(R.id.linearLayout1);
        View view = ll.getChildAt(0);
        if(view instanceof ListView) {
            ListView lView = (ListView) view;
            RowData rowData = (RowData) lView.getAdapter().getItem(position);
            catId = rowData.mCatId;
            catName = rowData.mTitle;
        }

        String url = "http://global.thinlenses.co.uk/virtualMirror/productlisting.php"; 
        String xml = "<?xml version=\"1.0\" encoding=\"utf-8\" ?>" + "<category><Id>" + catId + "</Id>"
                    + "<Data>" + "pList" + "</Data></category>";

        if(getIntent().getBooleanExtra("VM", false))
            new SpinnerHelper().serverCall(Category.this, "ProductListVM", url, xml, catName);
        else
            new SpinnerHelper().serverCall(Category.this, "ProductList", url, xml, catName);
    }

您可以为此使用上下文引用

Intent intent = new Intent(context,nextActivity.class);
context.startActivity(intent);
((Activity) context).finish();

您是否尝试过执行Category.this.finish（）？是的，Category是activity，SpinnerHelper.java不是activity的常规类。

  Handler handler = new Handler()
  {
    public void handleMessage(Message message)
    {
        if(isExecuted)
        {
            dialog.dismiss();
            isExecuted = false;

            if(result.equals("yes"))
            {
                  /////HERE i want to start the next activity and finish the Category(previous activity).

             }

Intent intent = new Intent(context,nextActivity.class);
context.startActivity(intent);
((Activity) context).finish();
