>我根据我从我发现的堆栈溢出问题中理解的内容修改了我的代码,如下所示
private static final String url = "http://****/get_items.php?keyword=%1$s";
String searchKey = getIntent().getStringExtra("2");
Final_url = String.format(url, searchKey);
当我像这样打印Final_url时
Toast.makeText(getApplicationContext(),"url = "+ Final_url, Toast.LENGTH_SHORT).show();
打印值始终为
url = http://*****/get_items.php?keyword=null
我错过了什么吗?
尝试:
"http://****/get_items.php?keyword=%s";
