Nearly everything works in a program I've been working on. As I make changes in the UI, everything is set correctly. For reasons I can't figure out, when I hit the enter button of my main UI the app force closes with an exception. From the log...
java.lang.IllegalStateException: Could not find a method enterMood(View) in the activity class com.loch.meaptracker.MainActivity for onClick handler on view class android.widget.Button with id 'enterButtonID'
Here's the program code. Eclipse doesn't flag anything for either errors or warnings. I'm at a bit of a loss and pretty burnt out looking at this. Any help would be greatly appreciated.

Please check the XML code . i think there in tag of your XML there is one attribute you have added android:onClick="enterMood".... try removing it and running it
use
android:onClick="dialogPop" instead
Your click handler is not in the right format. It needs to include a view parameter for the XML click handler to work properly.
public void getMood(View view){

I'm new in android and also new in English sorry my bad English...
I have learned android course at the academy.
My sentence may be wrong because it is written through a translator. I hope you understand with a generous heart.
Here's what I want:
If I click 15 days in Calendar View,
It is hoped that only the 15th day information will be shown in the Recyclerview. If I click on another date in calenderview, for example, 20 days, I hope that the 15th item will disappear and only the 20th item view will be displayed.
Here's what I'm trying to do.
When I click a date in a calendar view, I want to see the Item View corresponding to that date.

First you need to add new entry in your existing mArrayList as i am can see from your code you are adding all existing entries again but not new entry.
After that you need to set adapter again with new mArrayList only then you will be able to see new data in your recycler view.
I am trying to display a progress dialog inside a fragment.But progressbar.show() do not have any effect.However,I noticed a strange behaviour,if i call showPopUp() method twice,it does show the progress dialog,but unable to dismiss().

Try like this :

And if you wish to customize your dialog and put self created Layout in it.

dialog.show();

/**

public static void dismissProgressDialog() {

dialog.dismiss();
dialog = null;
}
}
} // End of main class over here ...
Replace this:-
progressDialog = new ProgressDialog(getContext(), ProgressDialog.THEME_HOLO_LIGHT);
with
progressDialog = new ProgressDialog(getActivity());
May be. you are showing two progressdialog and both of that progressbar on screen.. but when you dismiss your progressbar at that time the previous one is override by other one before you dismiss first one .. so the firstone is always in screen. that's the issue.
I tried everything.But none of the answers solved the issue.However,i solved it by overriding onResume() method in the fragment.
Thanks All.
I am creating a game app, which needs to allow the player to save and resume their position.
The save works fine, storing the room position, it retrieves the room position fine when clicking the "resume" button but doesn't take the player to the saved room position, it just starts the game from the beginning.
I think it maybe to do with this code, but after 8 hours of research, I still have no idea how to alter it:-
Intent value = new Intent(MainMenu.this, MainActivity.class);
startActivity(value);
Please help, thanks!

You are not passing the value to another activity.
Set it to intent like this:
int Value = sp.getInt("save", -1);
Log.w("LOG_TAG", "value: " + Value);
Intent value = new Intent(MainMenu.this, MainActivity.class);
value.putExtra("save", Value);
startActivity(value);
And in your MainActivity take the value using getIntent().getIntExtra().
Put it in your onCreate() method, after setContentView():
playerPos = getIntent().getIntExtra("save", 0);
and then use it to set player position.
Okay, I read a lot and thought I had this worked out but apparently not. What I'm trying to do is check to see if a file exists (in this case heapFile.csv) and if it doesn't to create it and then write a string to it. If the file does exist, then I want to append the string to the file. I get no errors when I run this though I do get a warning saying that it can't create the file although it actually does do so. However it's not writing the string to the file in either case. I'm probably just not using the right syntax or something but after staring at this for weeks I can't see the forest for the trees and find the problem. Aside from this one issue my program is working fine and if I can just get this working I can FINALLY finish this. Any help is incredibly appreciated.
Here's the java file. I think it's clear where the file creation/writing bit is.

Edited my question to include the manifest so you can see the permissions I've got. I think it's right but I'm not certain...

use this:
String file = heapFile.getAbsolutePath();
FileWriter heapFileWritter = new FileWriter(file, true);
getName() would give you just the name of the file. But you need to provide absolutepath for FileWriter.
First off I wanted to thank everyone for the help I've gotten on my last few questions. I've searched and done my best to figure out my latest problem but I've had no luck even after searching here. I'm trying to check to see if "heapFile.csv" exists and if it doesn't, to create the file and then write a string to it. If it does then I just want to append a string to it instead. I think what I have will do that but I keep getting an IOException along with it saying the file system is Read Only. I do have the manifest file changed to include accessing the sdcard and even used the android too to make a virtual sdcard in case that was the problem.
First here's the main activity java...

I think problem is in this line:
FileWriter heapFileWritter = new FileWriter(
heapFile.getName(), true);
instead try this:
FileWriter heapFileWritter = new FileWriter(
heapFile, true);
explanation:
heapFile.getName() refers to your file name so lets say heapFile.txt.
so when you ask FileWriter to write to this file. It doesn't know which file you are referring to. So it try to create the file. But wait! where it will create the file, as it has only the file name, not the complete path.
So even I am sure where it would think of creating the file, my guess is Root( I am not sure). Which is read-only hence the error.
public FileWriter(String fileName,
boolean append)
throws IOException
IOException - if the named file exists but is a directory rather than
a regular file, does not exist but cannot be created, or cannot be
opened for any other reason
