java - Android 错误 - 类膨胀错误

Question

我刚刚开始通过 Java 进行 android 开发(我以前只使用过 phonegap)。

我用一个简单的表单文本字段和发送按钮创建了我的第一个 hello world 项目，但它无法运行。

我的错误日志如下:

12-06 20:31:11.482: E/AndroidRuntime(32656): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.thesurvivor2299/com.example.thesurvivor2299.MainActivity}: android.view.InflateException: Binary XML file line #1: Error inflating class android.widget.RelativeLayout

由于有很多文件，我不确定最好提供哪个文件的代码。让我知道是哪个文件，我会将代码复制到这里。

主要 Activity .java:

public class MainActivity extends Activity {

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

@Override
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;
}

}

activity_main.xml:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@style/AppTheme"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainActivity" >

<TextView
    android:id="@+id/textView1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/hello_world" />

<EditText
    android:id="@+id/editText1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignLeft="@+id/textView1"
    android:layout_below="@+id/textView1"
    android:layout_marginTop="35dp"
    android:ems="10"
    android:inputType="textWebEditText"
    android:singleLine="true" />

<Button
    android:id="@+id/button1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignRight="@+id/textView1"
    android:layout_below="@+id/editText1"
    android:layout_marginTop="36dp"
    android:text="Send" />

</RelativeLayout>

如果有帮助，我可以发布任何代码

可以通过转到文件 R.java 并从您的日志中搜索错误条目(例如 0x7f0201f2)来修复此类错误。它将对应于一个变量。如果你查看这个条目的包含方法，它会告诉你它是否是一个字符串、id、dimen 等。 然后你可以在你的项目中搜索这个变量，看看它是否已经在你的资源文件中声明。
