[ "Adding a listener to a button inside a custom alertdialog crashes my app", "I have in my application a button which allows me to open an custom alertdialog. This alert dialog gets its content from an XML file: I have in it a button (called filterButton), radio button and a slider bar. Programatically, there are two more buttons added (OK, Cancel).\nWhen I open my dialog alert, the content is perfectly displayed but no events are created so far. (so no problem opening the alertdialog and displaying content)\n\nNow, I want to add a listener for my \"filterButton\". So as always, I declared my button (Button filterButton;), setOnClickListener this way (in my onCreate) : \n\nfilterButton = (Button) findViewById(R.id.filter_button); \nfilterButton.setOnClickListener(filter_listener);\n\n\nThen I define my listener : \n\nOnClickListener filter_listener = new OnClickListener() {\n\n @Override\n public void onClick(View v) {\n// showPopupMenu(v);\n } }; \n\n\nI commented out the method inside to make sure the problem doesn't come from this method. And so since I did this, when I try to run my app it just crashes when I try to open the activity where the button opening the alertdialog is. When I take off these few lines, it works again. I don't understand, it doesn't make sense, it's just a button with a listener, I have dozens like this and no problem so why is it problematic when it's in my alertdialog ? \n\nps: my logcat is useless as usual, just saying Fatal Error and nullpointerexception with no details. \n\nEDIT: I changed as suggested below to this : \n\nfilterButton = (Button) alertDialog.findViewById(R.id.filter_button);\nfilterButton.setOnClickListener(filter_listener); \n\n\nI put this here as it was underlining alertDialog in red if put at the beginning of the program, but it still crashes : \n\nOnClickListener dialog_listener = new OnClickListener() {\n\n @Override\n public void onClick(View v) {\n\n LayoutInflater myLayout = LayoutInflater.from(context);\n View dialogView = myLayout.inflate(R.layout.alertdialog_filter, null);\n\n AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(\n context);\n\n\n Bundle bundle = getIntent().getExtras();\n int filterVariable = bundle.getInt(\"filterVariable\");\n\n alertDialogBuilder.setTitle(\"Filter Mode\");\n\n alertDialogBuilder.setPositiveButton(\"OK\",\n new DialogInterface.OnClickListener() {\n public void onClick(DialogInterface dialog, int which) {\n\n }\n });\n\n\n alertDialogBuilder.setNegativeButton(\"Cancel\",\n new DialogInterface.OnClickListener() {\n public void onClick(DialogInterface dialog, int which) {\n\n }\n }); \n\n // set alertdialog_filter.xml to alertdialog builder\n alertDialogBuilder.setView(dialogView);\n\n // create alert dialog\n AlertDialog alertDialog = alertDialogBuilder.create();\n\n filterButton = (Button) alertDialog.findViewById(R.id.filter_button);\n filterButton.setOnClickListener(filter_listener);\n\n\n\n // show it\n alertDialog.show();\n }\n}; \n\n\nThe difference is, now it doesn't crash when I open the activity but when I click on the button supposed to open the alertdialog." ]

[ "Yet another NoClassDefFoundError puzzle", "I created two jar files, my.common.jar which contain helper classes and methods (mostly static methods). I also created a jar file, test.jar with a main method that calls a static method in a class in my.common.jar.\n\nEverything works fine when I launch main like this:\n\njava -classpath path/to/myjars/my.common.jar:./test.jar test.Tester\n\n\nTester is the class in test.jar that contains method main.\n\nBut I get NoClassDefFoundError my/common/Myclass when I run it this way:\n\njava -classpath path/to/myjars/my.common.jar -jar test.jar\n\n\nI tried so hard, but I am not able to figure out why it fails or how to resolve this issue. I do appreciate your help.\n\n----- addendum ----\nI forgot to mention that the manifest file in test.jar looks like so:\n\n Manifest-Version: 1.0\n Build-Jdk: 1.6.0_13\n Created-By: Apache Maven\n Main-Class: test.Tester\n Archiver-Version: Plexus Archiver" ]
