Android SDK在仿真器中运行的Eclipse问题

Question

我正在构建android应用程序的布局。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，我正在收到错误。我假设它是一个布局渲染错误。我在哪里可以查看错误，因为在Eclipse中没有显示错误。

主入口 - >

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; 
} 

}

错误--->

如果我理解你的问题正确，则logcat的是系统，将让你在Eclipse中遇到这些问题。

http://developer.android.com/tools/help/logcat.html

一旦安装，你可以在Eclipse中通过从Eclipse任务栏选择“窗口”，然后按照这个顺序查看。

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