我刚刚在 Eclipse 中构建了一个新的 Android 项目,到目前为止,我只有一个包含一个活动的包(来自 Eclipse 的自动生成代码),我所做的只是在 main.xml 布局文件中添加两个按钮。
当我尝试调试应用程序时,模拟器崩溃并且我收到错误“Binary XML file line #31: Error inflating class android.widget.FrameLayout”。
我什至没有使用 FrameLayout!
这是布局文件:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:background="#99CCFF">
<Button
android:id="@+id/btn1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="New" />
<Button
android:id="@+id/btn2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Save" />
</LinearLayout>
这是主要的 Activity 文件(同样,这只是 Eclipse 在您创建新项目时生成的默认代码):
package com.myapp.main;
import android.app.Activity;
import android.os.Bundle;
public class MyApp extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
}
只是为了它,这也是清单文件:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.myapp.main"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="8" />
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name" >
<activity
android:name="com.myapp.main.MyApp"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
据我所知,这是 99% 的自动生成的代码,我看不出为什么我什至不使用 FrameLayout 时会在“FrameLayout”上得到 InflateException。
所以很迷茫...
这是我在 LogCat 中得到的:
