My problem is that when I run the program, it crashes immediately. I'm not sure what's going wrong. I am currently trying to adapt another multiple checkbox program to work for my needs: 'http://pulse7.net/android/android-check-box-example/'.
Essentially I have four grades of foam, and multiple thicknesses, so each grade, if checked in the checkbox, will need to lead to a different method. Currently, the Toast.makeText parts are just a placeholder for what will go there eventually once this part gets figured out :)
Cheers!
You must findViewById() in onCreate() method after setContentView() call.
public class MainActivity extends Activity {
CheckBox chkMD;
CheckBox chkHD;
CheckBox chkYE;
CheckBox chkOE;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_price_estimator);
chkMD = (CheckBox) findViewById(R.id.checkBox1);
chkHD = (CheckBox) findViewById(R.id.checkBox2);
chkYE = (CheckBox) findViewById(R.id.checkBox3);
chkOE = (CheckBox) findViewById(R.id.checkBox4);
// Attach listeners to the checkboxes
chkMD.setOnCheckedChangeListener(this);
chkHD.setOnCheckedChangeListener(this);
chkYE.setOnCheckedChangeListener(this);
chkOE.setOnCheckedChangeListener(this);
}
}

the weird thing about this code is; while running the button changes the text value correctly in the first pager, and the seckond one but when it comes the third one while it changes the value it resets the first pagers shown value but the getText() method inherits the correct value but the text is frozen and it cant be changed any more, after that the other page's values cant be changed either, but the getText() method still works fine and gets the correct value.
any idea will speed up my debuging process thanx anyway...
adding this snipped solved the problem, it is a must to define borders to the pager
#Override
protected void onCreate(Bundle savedInstanceState) {
...
int size = sliderAdapter.slide_headings.length;
AktifHareket.setOffscreenPageLimit(size);
On the main screen I have 7 buttons (days) and a fragment.
For every day of the week I wanted to generate a fragment with some EditTexts and a ListView, but creating 7 fragments with the same layout and almost the same class content seems too repetitive.
I only did it for Monday and Tuesday.
The only difference between MondayFragment and TuesdayFragment is that in TuesdayFragment I renamed the variable mondayTV to tuesdayTV and in layout I changed the ids of the submit button and the ListView. Also the key for Bundle is different. I don't think it's worth posting it since it's so similar to MondayFragment.
I want to know if it's possible to create a fragment template and use it to generate a fragment for every button of the activity given this code I wrote. There is still a lot to work on when it comes to functionality but I can't get this idea out of my head.

String contentDescription = btn.getContentDescription().toString();
getSupportFragmentManager().beginTransaction()
.replace(R.id.daysfragment, new DayFragment(contentDescription))
.addToBackStack(null)
.commit();
});
}
}
In MainActivity openFragment() method takes a Button parameter and with that Button and sets onClickListener to that Button. When you click any Button it gets content description from that Button and passing it to Fragment and opens that Fragment with that content description.

Heres a small Class used to hide softkeyboard thats called in DiceActivity
import android.app.Activity;
import android.content.Context;
import android.view.View;
import android.view.inputmethod.InputMethodManager;
/**
* http://stackoverflow.com/questions/1109022/close-hide-the-android-soft-keyboard
* Used to close soft keyboard
*/
public class Utils
{
public static void hideKeyboard(Activity activity)
{
// Check if no view has focus:
View view = activity.getCurrentFocus();
if (view != null)
{
InputMethodManager inputManager = (InputMethodManager) activity.getSystemService(Context.INPUT_METHOD_SERVICE);
inputManager.hideSoftInputFromWindow(view.getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);
}
}
}
Your method private List<Integer> rollDice(int chance, int amount) returns a list of Integer. And according to your comment inside the method it should have multiple numbers in it.
But this method always returns only one number.
Now you invoke this method here:
for (int i=0;i <number; i++)
{
diceList.add(i, rollDice(sides,number).get(i));
}
You are invoking this method in a loop. Storing the results in a NEW list.
You get an exception because in the second loop get(i) is 1 and there is only 1 entry in this list on index 0.
To correct this is should read: .get(0)
Also this kind of implementation is very messy. Please take a paper and a pencil to figure it out.
I have had this problem crop up a few times and I can't figure out why it should happen. What happened was after moving some stuff around my TextView box ended up on top of an EditText box, which is no good. So I went and moved the TextView box to the bottom of the screen. When I did that, the app would crash when I tried to access the piggybank. However, if I move the TextView box up to the top again, it works fine.. I really don't get it. Anyways, this is the error that I got

I have searched for an answer but they all seem to be slightly different situations. Any ideas? Thanks. And like I said, this works fine if the TextView box is overlapping the quarters EditText box.

Try cleaning your project on Eclipse. It often fixes that kind of problems.
