java – setContentView上的另一个资源$NotFoundException（java setcontenttype）
Stack Overflow上有很多资源$NotFoundException问题,我已经审阅了它们,并尝试了各种建议无济于事.
我有一个完美的工作布局,显示一些图形与下面的一些按钮,我修改了一些按钮,并开始得到这个错误.我没有看到我的更改有什么问题,但只是为了缩小它我删除了所有按钮,所以现在我只有一个带有ImageView的LinearLayout,我仍然得到错误.我的Java：
try {
setContentView(R.layout.graphics);
}
catch (Exception e) {
Log.d("DGraphActivity", "setContentView crash");
}
我的XML：
<?xml version="1.0" encoding="UTF-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal">
<ImageView
android:id="@+id/image2"
android:layout_width="0px"
android:layout_weight="2"
android:layout_height="match_parent"
android:scaleType="fitCenter">
</ImageView>
</LinearLayout>
错误说android.content.res.Resources $NotFoundException：资源ID#0x7f030005.
在R.java文件中,资源用图形标识. . .
public static final class layout {
public static final int addcomment=0x7f030000;
public static final int areyousure=0x7f030001;
public static final int downarrow=0x7f030002;
public static final int downleftarrow=0x7f030003;
public static final int downrightarrow=0x7f030004;
public static final int graphics=0x7f030005;
public static final int infofromoperator=0x7f030006;
我删除了gen文件夹并做了一个干净的项目没有任何改进.我还重新启动了我的电脑并明确关闭了该项目. graphics.xml文件没有明显的错误 – 它存在于与我所有其他XML文件相同的文件夹中;它没有写保护或隐藏. Eclipse不会标记任何错误或警告.
提前致谢.
解决方法:
我在Android开发者谷歌小组得到了答案,我也发布了这个问题.这位富有洞察力的程序员是“Bob Smith”,只是为了给予应有的信用额度.
我的错误是它正在寻找的资源不在正确的res文件夹中.我的应用在平板电脑上以横向模式运行.在清单中,一切都被限制为以这种方式运行(实际上在代码中,它被限制为在公司随产品提供的一个特定平板电脑上运行).所有资源和布局文件都存在于layout-land中.鲍勃不知道这些,但他问了一个关键问题：我的资源文件真的在正确的res文件夹中吗？
Adapter.getView上的参数convertView上的IllegalArgumentException
java.lang.IllegalArgumentException: Parameter specified as non-null is null: method kotlin.jvm.internal.Intrinsics.checkParameterIsNotNull, parameter convertView
Adapter.getView

这是android的logcat.
我尝试使用Java正常工作的基本适配器,在Adapter或其他适配器中出了点问题.
我尝试使用公共构造函数,并且发现数组列表计数3已检查.总是在getView崩溃
MyAdapter代码：：
inner class MyAppAdapter constructor(private val parkingList: ArrayList<App>, private val mContext: Context) : BaseAdapter() {
override fun getCount(): Int {
return this.parkingList.size
}
override fun getItem(position: Int): Any {
return position
}
override fun getItemId(position: Int): Long {
return position.toLong()
}
override fun getView(position: Int, convertView: View, parent: ViewGroup): View? {
val viewHolder: ViewHolder
var rowView: View? = convertView
if (rowView == null) {
rowView = LayoutInflater.from(mContext).inflate(R.layout.item_more_apps, parent, false)
viewHolder = ViewHolder()
viewHolder.appIcon = rowView.findViewById(R.id.appIcon)
viewHolder.appName = rowView.findViewById(R.id.appName)
viewHolder.appDescription = rowView.findViewById(R.id.appDescription)
rowView.tag = viewHolder
} else {
viewHolder = convertView.tag as ViewHolder
}
viewHolder.appName!!.text = String.format("%s", this.parkingList[position].name)
viewHolder.appDescription!!.text = String.format("%s", this.parkingList[position].description)
Glide.with(applicationContext).load(this.parkingList[position].icon).into(viewHolder.appIcon!!)
rowView?.setonClickListener {
try {
startActivity(Intent("android.intent.action.VIEW", Uri.parse("market://details?id=" + this@MyAppAdapter.parkingList[position].link)))
} catch (e: ActivityNotFoundException) {
startActivity(Intent("android.intent.action.VIEW", Uri.parse("http://play.google.com/store/apps/details?id=" + this@MyAppAdapter.parkingList[position].link)))
}
}
return rowView
}
inner class ViewHolder {
var appDescription: TextView? = null
var appIcon: ImageView? = null
var appName: TextView? = null
}
}
在AsyncTask中使用-> onPostExecute
myAppAdapter = MyAppAdapter(appArrayList, applicationContext)
lvPoses!!.adapter = myAppAdapter
像这样清除变量
lateinit var myAppAdapter: MyAppAdapter
private val appArrayList = ArrayList<App>()
private var lvPoses: ListView? = null
解决方法:
如果尚未创建视图,则convertView可以为null.修复参数声明：
override fun getView(position: Int, convertView: View?, parent:
ViewGroup): View? {
...
}
android – java.lang.RuntimeException：无法实例化活动ComponentInfo / java.lang.ClassNotFoundException
我在设备上运行时遇到此错误.我一直在浏览这个问题,我很确定我没有提到的问题.我的两个活动都在
AndroidManifest中声明,而intent过滤器就在那里.我没有任何库(除了v4支持库,但声明它不会改变问题).我尝试用.MainActivity替换我的Manifest carpedujourproductions.quickpronote.MainActivity,但仍然没有运气.我正在运行Android Studio 0.2.5,所以我找不到如何解决与Java Build Path / Order and Export相关的潜在问题
我忍不住注意到我的MainActivity图标在树的左上角有一个灰色的十字架.
logcat的：

随意浏览AndroidManifest,MainActivity.java,FirstRun.java等代码here.
解决方法
您的MainActivity.java被排除在编译之外,因此该类不包含在.apk中.删除行：
<file url="file://$PROJECT_DIR$/src/carpedujourproductions/quickpronote/MainActivity.java" />
来自.idea / compiler.xml文件的excludeFromCompile部分(或者您可以从IDE设置执行此操作).
android – java.lang.RuntimeException：无法实例化活动ComponentInfo … java.lang.ClassNotFoundException
我有一个问题,我正在处理三天,我试图阅读不同的答案,但它没有帮助.
也有人可以帮助我！
我将Ancdroid应用程序作为客户端编写为一个安静的Web服务.我可以从数据库中获取数据而没有问题,但我的问题是我使用的2个活动来处理来自数据库的这个文件.
主要活动
public class MainActivity extends Activity {
private static final String SERVICE_URL = "http://10.0.2.2:8080/.....";
private static final String TAG = "AndroidRESTClientActivity";
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void retrieveSampleData(View vw) {
EditText idTxt = (EditText) findViewById(R.id.id_textfield);
String id = idTxt.getText().toString();
String sampleURL = SERVICE_URL +"daten/"+id ;
Log.d("getrespond()", "service calling");
String url =sampleURL;
RestClient client = new RestClient(url);
try{
client.Execute(RestClient.RequestMethod.GET,this.getApplicationContext());
}
catch (Exception e) {
String error = String.valueOf(e);
Log.d("**********client.Execute(RequestMethod.GET);***********",error);
}
try {
if(client.getResponseCode() == 200) {
Log.d("Response is 200", String.valueOf(client.getResponse().length()));
System.out.println(this.getFilesDir().getPath().toString());
File daten= client.getResponse();
System.out.println(daten.getName());
Toast.makeText(this.getApplicationContext(), "Responce is "+String.valueOf(client.getResponseCode()), 2000).show();
} else {
String error = String.valueOf(client.getResponse());
Log.d("Response*********** not 200 ************", String.valueOf(client.getResponse()));
}
}catch (Exception e) {
e.printstacktrace();
Log.d("EXCEPTIONI IS 3", e.toString());
// Todo: handle exception
}
startActivity(new Intent("android.intent.action.LINEGRAPH"));
我从主要开始的另一项活动：
public class lineGraph extends Activity{
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_line_graph);
}
@Override
protected void onResume() {
super.onResume();
if (mChartView == null) {
LinearLayout layout = (LinearLayout) findViewById(R.id.chart);
try {
mChartView = ChartFactory.getLineChartView(this, getDemoDataset(),
getDemoRenderer());
} catch (IOException e) {
// Todo Auto-generated catch block
e.printstacktrace();
}
layout.addView(mChartView, new LayoutParams
(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
} else {
mChartView.repaint();
}
}
