从一个活动传递到另一个活动的字符串变量 [英] string variable passing from one activity to another

问题描述

我正在开发基于youtube视频搜索的新应用.
几乎所有部分都完成了.但我有一个问题是，我无法从一个班级到另一个班级搜索到的视频显示为视频流.

我将一个字符串变量从一个类传递到另一个类，因为视频是由一项活动决定的，而在另一项活动中进行流式传输的.我可以访问字符串变量，但它显示强制关闭错误消息.
请帮助我先生...........

推荐答案

通常，您使用Intent将数据从一个活动传递到另一个活动.

Normally you pass data from one activity to another using the Intent.

Intent intent = new Intent(SearchActivity.this, VideoActivity.class);
intent.putString(VideoActivity.SEARCH_PARAMETER_KEY, searchResult);
startActivity(intent);

其中SEARCH_PARAMETER_KEY是在VideoActivity中定义的常量字符串，而searchResult是包含实际参数值的字符串.

where SEARCH_PARAMETER_KEY is a constant String defined in your VideoActivity, and searchResult is a String containing the actual parameter value.

请添加一些代码段以更好地呈现问题陈述.
