我运行了一次我的代码，一切正常，我又运行了一次，但现在每次都崩溃了。 LogCat 给了我这个:

我有三个 Activity :
package com.androidbook.triviaquiz;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.TextView;
public class QuizMenuActivity extends QuizActivity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.menu);
ListView menuList = (ListView) findViewById(R.id.listView1);
String[] items = { getResources().getString(R.string.itemplay),
getResources().getString(R.string.itemscores),
getResources().getString(R.string.itemsettings),
getResources().getString(R.string.itemhelp) };
ArrayAdapter<String> adapt = new ArrayAdapter<String>(this, R.layout.menu, items);
menuList.setAdapter(adapt);
menuList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View itemClicked, int position, long id) {
// Note: if the list was built "by hand" the id could be used.
// As-is, though, each item has the same id
TextView textView = (TextView) itemClicked;
String strText = textView.getText().toString();
if (strText.equalsIgnoreCase(getResources().getString(R.string.itemplay))) {
// Launch the Game Activity
startActivity(new Intent(QuizMenuActivity.this, QuizGameActivity.class));
} else if (strText.equalsIgnoreCase(getResources().getString(R.string.itemhelp))) {
// Launch the Help Activity
startActivity(new Intent(QuizMenuActivity.this, QuizHelpActivity.class));
} else if (strText.equalsIgnoreCase(getResources().getString(R.string.itemsettings))) {
// Launch the Settings Activity
startActivity(new Intent(QuizMenuActivity.this, QuizSettingsActivity.class));
} else if (strText.equalsIgnoreCase(getResources().getString(R.string.itemscores))) {
// Launch the Scores Activity
startActivity(new Intent(QuizMenuActivity.this, QuizScoresActivity.class));
}
}
});
}
}
这个:
package com.androidbook.triviaquiz;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.TextView;
public class QuizMenuActivity extends QuizActivity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.menu);
ListView menuList = (ListView) findViewById(R.id.listView1);
String[] items = { getResources().getString(R.string.itemplay),
getResources().getString(R.string.itemscores),
getResources().getString(R.string.itemsettings),
getResources().getString(R.string.itemhelp) };
ArrayAdapter<String> adapt = new ArrayAdapter<String>(this, R.layout.menu, items);
menuList.setAdapter(adapt);
menuList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View itemClicked, int position, long id) {
// Note: if the list was built "by hand" the id could be used.
// As-is, though, each item has the same id
TextView textView = (TextView) itemClicked;
String strText = textView.getText().toString();
if (strText.equalsIgnoreCase(getResources().getString(R.string.itemplay))) {
// Launch the Game Activity
startActivity(new Intent(QuizMenuActivity.this, QuizGameActivity.class));
} else if (strText.equalsIgnoreCase(getResources().getString(R.string.itemhelp))) {
// Launch the Help Activity
startActivity(new Intent(QuizMenuActivity.this, QuizHelpActivity.class));
} else if (strText.equalsIgnoreCase(getResources().getString(R.string.itemsettings))) {
// Launch the Settings Activity
startActivity(new Intent(QuizMenuActivity.this, QuizSettingsActivity.class));
} else if (strText.equalsIgnoreCase(getResources().getString(R.string.itemscores))) {
// Launch the Scores Activity
startActivity(new Intent(QuizMenuActivity.this, QuizScoresActivity.class));
}
}
});
}
}
还有这个:
package com.androidbook.triviaquiz;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
public class QuizGameActivity extends QuizActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.game);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
super.onCreateOptionsMenu(menu);
getMenuInflater().inflate(R.menu.gameoptions, menu);
menu.findItem(R.id.help_menu_item).setIntent(new Intent(this, QuizHelpActivity.class));
menu.findItem(R.id.settings_menu_item).setIntent(new Intent(this, QuizSettingsActivity.class));
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
super.onOptionsItemSelected(item);
startActivity(item.getIntent());
return true;
}
}
有人能告诉我这段代码有什么问题吗？就像我之前说的，我所做的就是重新启动它。这些是您唯一需要弄清楚的事情吗，也许是 list ？

最佳答案
您必须指定您在 R.layout.menu 中使用的 TextView ID
改变这个:
ArrayAdapter<String> adapt = new ArrayAdapter<String>(this, R.layout.menu, items);
为此:
ArrayAdapter<String> adapt = new ArrayAdapter<String>(this, R.layout.menu, R.id.YOUR_TEXT_VIEW, items);
关于java - 非法状态异常 : ArrayAdapter requires the resource ID to be a TextView，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/15940287/
我需要在客户计算机上运行Ruby应用程序。通常需要几天才能完成(复制大备份文件)。问题是如果启用sleep，它会中断应用程序。否则，计算机将持续运行数周，直到我下次访问为止。有什么方法可以防止执行期间休眠并让Windows在执行后休眠吗？欢迎任何疯狂的想法;-) 最佳答案 Here建议使用SetThreadExecutionStateWinAPI函数，使应用程序能够通知系统它正在使用中，从而防止系统在应用程序运行时进入休眠状态或关闭显示。像这样的东西:require'Win32API'ES_AWAYMODE_REQUIRED=0x0
我真的很习惯使用Ruby编写以下代码:my_hash={}my_hash['test']=1Java中对应的数据结构是什么？ 最佳答案 HashMapmap=newHashMap();map.put("test",1);我假设？ 关于java-等价于Java中的RubyHash，我们在StackOverflow上找到一个类似的问题： https://stackoverflow.com/questions/22737685/
当我的预订模型通过rake任务在状态机上转换时，我试图找出如何跳过对ActiveRecord对象的特定实例的验证。我想在reservation.close时跳过所有验证!叫做。希望调用reservation.close!(:validate=>false)之类的东西。仅供引用，我们正在使用https://github.com/pluginaweek/state_machine用于状态机。这是我的预订模型的示例。classReservation["requested","negotiating","approved"])}state_machine:initial=>'requested
我正在学习Rails，并阅读了关于乐观锁的内容。我已将类型为integer的lock_version列添加到我的articles表中。但现在每当我第一次尝试更新记录时，我都会收到StaleObjectError异常。这是我的迁移:classAddLockVersionToArticle当我尝试通过Rails控制台更新文章时:article=Article.first=>#我这样做:article.title="newtitle"article.save我明白了:(0.3ms)begintransaction(0.3ms)UPDATE"articles"SET"title"='dwdwd
在Cooper的书BeginningRuby中，第166页有一个我无法重现的示例。classSongincludeComparableattr_accessor:lengthdef(other)@lengthother.lengthenddefinitialize(song_name,length)@song_name=song_name@length=lengthendenda=Song.new('Rockaroundtheclock',143)b=Song.new('BohemianRhapsody',544)c=Song.new('MinuteWaltz',60)a.betwee
我早就知道Ruby中的“常量”(即大写的变量名)不是真正常量。与其他编程语言一样，对对象的引用是唯一存储在变量/常量中的东西。(侧边栏:Ruby确实具有“卡住”引用对象不被修改的功能，据我所知，许多其他语言都没有提供这种功能。)所以这是我的问题:当您将一个值重新分配给常量时，您会收到如下警告:>>FOO='bar'=>"bar">>FOO='baz'(irb):2:warning:alreadyinitializedconstantFOO=>"baz"有没有办法强制Ruby抛出异常而不是打印警告？很难弄清楚为什么有时会发生重新分配。 最佳答案
我正在尝试使用boilerpipe来自JRuby。我看过guide从JRuby调用Java，并成功地将它与另一个Java包一起使用，但无法弄清楚为什么同样的东西不能用于boilerpipe。我正在尝试基本上从JRuby中执行与此Java等效的操作:URLurl=newURL("http://www.example.com/some-location/index.html");Stringtext=ArticleExtractor.INSTANCE.getText(url);在JRuby中试过这个:require'java'url=java.net.URL.new("http://www
对于作为String#tr参数的单引号字符串文字中反斜杠的转义状态，我觉得有些神秘。你能解释一下下面三个例子之间的对比吗？我特别不明白第二个。为了避免复杂化，我在这里使用了'd'，在双引号中转义时不会改变含义("\d"="d")。'\\'.tr('\\','x')#=>"x"'\\'.tr('\\d','x')#=>"\\"'\\'.tr('\\\d','x')#=>"x" 最佳答案 在tr中转义tr的第一个参数非常类似于正则表达式中的括号字符分组。您可以在表达式的开头使用^来否定匹配(替换任何不匹配的内容)并使用例如a-f来匹配一
我目前正在使用以下方法获取页面的源代码:Net::HTTP.get(URI.parse(page.url))我还想获取HTTP状态，而无需发出第二个请求。有没有办法用另一种方法做到这一点？我一直在查看文档，但似乎找不到我要找的东西。 最佳答案 在我看来，除非您需要一些真正的低级访问或控制，否则最好使用Ruby的内置Open::URI模块:require'open-uri'io=open('http://www.example.org/')#=>#body=io.read[0,50]#=>"["200","OK"]io.base_ur
我只想对我一直在思考的这个问题有其他意见，例如我有classuser_controller和classuserclassUserattr_accessor:name,:usernameendclassUserController//dosomethingaboutanythingaboutusersend问题是我的User类中是否应该有逻辑user=User.newuser.do_something(user1)oritshouldbeuser_controller=UserController.newuser_controller.do_something(user1,user2)我
