Android小部件使用putextra启动新活动
我正在使用JSON。我编写了可以加载JSON（图像和文本）并在ListView中显示数据的代码。（在ListView中，我启动新活动） 我还编写了一个appwidget（stackview小部件），我可以在stackview小部件中显示JSON内容，例如，如果我单击第5项，它启动一个新的活动，允许用户阅读第五条新闻。我可以在widget click上启动新活动，但如何根据项目位置启动新的结果活动 这是我的代码：Android小部件使用putextra启动新活动,android,json,android-appwidget,Android,Json,Android Appwidget,我正在使用JSON。我编写了可以加载JSON（图像和文本）并在ListView中显示数据的代码。（在ListView中，我启动新活动） 我还编写了一个appwidget（stackview小部件），我可以在stackview小部件中显示JSON内容，例如，如果我单击第5项，它启动一个新的活动，允许用户阅读第五条新闻。我可以在widget click上启动新活动，但如何根据项目位置启动新的结果活动 这是我的代码： public class MainActivity extends Activity
