Question

我有一个ListView，当我点击它将调用的类别时会显示几个String，并弹出一个对话框选项菜单，其中包含英语，印地语和取消选项。当用户单击Listview中的一个类别时，将触发onClicklistener，例如＆＃34; Novel＆＃34;，＆＃34; Book＆＃34;或＆＃34;播放＆＃34;。我想在这里做的是，当用户点击＆＃34; Book＆＃34;并选择语言英语选项，我想将category_id和language_id传递给下一个activity.category_id和language_id是我从服务器响应中获得的json对象。所以我需要从listview中选择category_id并将其传递给下一个活动以及在对话框中选择的language_id。

如果有可能那么如何？在此先感谢您的帮助。

holder.imageView.setImageUrl(Config.TAG_IMAGE_URL+category.getImage(), imageLoader);
    holder.textViewName.setText(category.getName());
    category_id = category.getId();
    language_id = category.getLanguage_id();
    holder.imageView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View arg0) {
            handleLanguageDialog();

            }

    });


}

private AlertDialog handleLanguageDialog() {
    AlertDialog.Builder builder = new AlertDialog.Builder(context);
    builder.setTitle("Select Language")
            .setItems(R.array.lang, new DialogInterface.OnClickListener()                 {
                public void onClick(DialogInterface dialog, int which) {
                    // The 'which' argument contains the index position
                    // of the selected item
                    switch(which)
                    {
                        case 0:// English


                            break;
                        case 1://Bengali

                            break;
                    }
                }
            });
    return builder.create().show();

Answer 1

在你的开关盒里面这样传递

case 0:
Intent intent = new Intent(YourCurrentActivity.this, Destination.class);
intent.putExtra("category_key", category_id);
intent.putExtra("language_key", language_id);
startActivity(intent);

Answer 2

 Intent intent = new Intent(SourceActivity.this,destinationAvtivity.java);
    intent.putExtra("category_id",109);
    startActivity(theintent);

Answer 3

在您的第一个活动中传递此类数据

Intent intent = new Intent(this, NextActivity.class);
intent.putExtra("CATEGORY_ID", category_id);
intent.putExtra("LANGUAGE_ID", language_id);
startActivity(intent);

现在，您的下一个活动会收到这样的数据

String cat_id = getIntent().getExtras().getString("CATEGORY_ID");
String cat_id = getIntent().getExtras().getString("LANGUAGE_ID");

如何将值传递给另一个活动，其id为从对话框中单击的选项
