Android和Netbeans：“意外停止”

Question

我是Android的新手，但对于Java而言还行，并且更喜欢Netbeans到Eclipse。我试图让HelloAndroid应用程序运行，但没有成功。

package com.ex.helloandroid; 

import android.app.Activity; 
import android.os.Bundle; 
import android.widget.TextView; 

public class HelloAndroid extends Activity { 
/** Called when the activity is first created. */ 
@Override 
public void onCreate(Bundle savedInstanceState) 
{ 
    super.onCreate(savedInstanceState); 
    TextView tv = new TextView(this); 
    tv.setText("Hello, Android"); 
    setContentView(tv); 
} 
} 

清单：

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
    package="com.ex.helloandroid" 
    android:versionCode="1" 
    android:versionName="1.0"> 
<application android:label="@string/app_name" > 
    <activity android:name="HelloAndroid" 
       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> 

这编译OK，并在仿真器和我的手机都安装OK。但是当我尝试运行它时，我遇到了可怕的“应用程序HelloAndroid（process com.ex.helloandroid）意外停止了，请重试。”

这里的logcat的：

我花了几天的时间，使这项工作...安装了NetBeans的新副本，重新安装NBAndroid，重新安装Android SDK中，Google搜索与代码拨弄。有人可以帮忙吗？

感谢

Answer 1

该项目看上去一切正常。我用你的活动和清单，没有问题。尝试清理你的项目。 GO到项目 - >清洁

Answer 2

setContentView(R.layout.main); 

把你的main.xml。使用DroidDraw创建main.xml并拨打电话setContentView(R.layout.main);而不是setContentView(tv);
