Java 在Emulator中运行的Android SDK Eclipse问题

我正在为android应用程序构建布局。运行应用程序时，我没有收到任何错误；但是，当应用程序在模拟器中启动时，我立即收到一个错误。我假设这是布局渲染错误。在哪里可以查看错误，因为Eclipse中没有显示错误

如果我正确理解了您的问题，那么Logcat是一个允许您在Eclipse中排除这些问题的系统

安装后，您可以通过从Eclipse任务栏中选择“窗口”并遵循以下顺序在Eclipse中查看它

---

窗口->显示视图->其他->查找并打开Android文件夹->选择Logcat。

请发布您的代码。您能提到您得到的错误行吗？添加了主java文件，它只是eclipse创建的标准。如果您需要查看任何其他文件，请告诉我您遇到了什么错误？请！！在LogCat中发布错误详细信息

public class MainActivity extends Activity {


protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
}



public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}
