Question

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，我立刻收到错误。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Eclipse中没有显示错误。

主要参赛作品 - ＆gt;

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---＆gt;

如果我正确理解你的问题，那么Logcat就是让你在Eclipse中解决这些问题的系统。

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

安装完成后，您可以通过从Eclipse任务栏中选择“Window”并按照此顺序在Eclipse中查看它。

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