Question

我有可搜索的国家ListView。当我单击国家列表项而不进行搜索时，它可以正常工作。但是当我在搜索框中键入Brazil并单击Brazil时，请打开Country_Details.Java Activity并传递Afganistan详细信息。当我在搜索框中键入巴西并单击巴西时，我希望在WebView中传递巴西详细信息。

问题在于此处，您在静态位置调用webview，而是相应地调用您的数组列表如下所示。

    if( array_list.get(position).equals("Afghanistan")){
    Intent intent = new Intent(Search_Country.this, Country_Details.class);                            intent.putExtra("header", getString(R.string.html_afganistan));                                       startActivity(intent);
}

当我搜索listview项目然后单击欲望项目时，它会打开列表视图的第一个位置
