本文介绍了在Android开发中遇到的setContentView方法调用时出现的R文件冲突问题及其解决办法。作者指出，系统自动导入的android.R可能会覆盖自定义的R文件导致错误，并提供了删除错误导入及正确导入自定义R文件的方法。

setContentView(R.layout.name);是显示一个布局文件的，我做这个简单的安卓的项目时name处报错。

原因是：      import android.R;      这句是系统自动给你导入的，它会覆盖掉你的gen文件夹中的R文件，所以会出错

解决方法：删掉这一行，并且导入R文件所在包。

还有与此同时你添加的控件例如：ListView myListView = (ListView)findViewById(R.id.other_myListView);    可能出现的错误也就同时解决了。

PackageInstall 阅读packageInstall源码我们的突破口是从程序的窗口开始,首先查看AndroidManifest文件中activity的定义 PackageInstallerActivity: 窗口指定了两个IntentFilter,因此两种方式调用该窗口,两种方式都定义了action:android.intent.action.INSTALL_PAC

用法： intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION); Intent chooserIntent = Intent.createChooser(intent, "分享到:"); VActivityManager.get().startActivity(chooserIntent, 0); 来看下源码： public static Intent createChooser(Intent target, CharSequence title)

在R.layout里面明明看到自动生成了默认的布局activity_main，在这里引用就出错。 在import里面果然找到这么一句： import android.R; 删掉这一句就正常了。出现这个问题的原因是，如果你在R.java还没有来得及自动生成的时候选择了fix imports，那么Eclipse就会自动帮你导入android.R这个包，就会覆盖掉本地的R.java，所以就导致了你...

刚开始学习android开发。看看视频，照着视频学习学习，从非常简单的项目开始，由于我以前从来没用过java,对eclipse 环境不熟悉，经常会犯很多低级的错误，这不，今天就犯了一个，调了好几次，也不知道因为什么。在网上搜索一下，终于找到答案，我记下来，以后在犯错误的时候好有地儿找。 事情是这样的，我建了一android app项目,在Activity.xml上增加一个按钮控件，然后回...

今天在写Android代码的过程中，编译器一直报错，错误出在这一行代码： setContentView(R.layout.activity_main) 提示信息是: activity_main cannot be resolved or is not a field 我就觉得很奇怪，我在R.layout里面明明看到自动生成了默认的布局activity_main，为什么在这里引用就出错呢

刚刚开始玩Android，学习过程中复制粘贴了一部分代码，没想到就出了问题，一直在R.layout.main那儿报错，在网上找了方法，什么升级SDK，刷新工程都没用。 后来在res这个文件夹下的layout文件夹下面看到只有activity_main这个东西， 于是将main改为activity_main就没问题了
