I get a nullpointerexception when I do this: EditText[] answers; //At the oncreate method

  • 0

I get a nullpointerexception when I do this:

EditText[] answers;

//At the oncreate method I do this:this is set after the setContent() method.

   answers=new EditText[6];
     answers[0]=(EditText) findViewById(R.id.editText1);
     answers[1]=(EditText) findViewById(R.id.editText2);
     answers[2]=(EditText) findViewById(R.id.editText3);
     answers[3]=(EditText) findViewById(R.id.editText4);
     answers[4]=(EditText) findViewById(R.id.editText5);
     answers[5]=(EditText) findViewById(R.id.editText6);

In the onClickListener of the button I put this:

nextQuestion_btn.setOnClickListener(new View.OnClickListener() 
{
    for(EditText item : answers) { 
        if(item.getText().toString().equals("")) { //nuller Exception here
            editTextIsEmpty=true;
        break;
        }
    }
}

why do I get a nullpointerexception… in the if statement?

UPDATE;
I put all the EditText into an array. All the code is inside the onCreate method

This is what I get:

    answers = new EditText[7];
answer1 = (EditText) findViewById(R.id.editText1);
answer2 = (EditText) findViewById(R.id.editText2);
answer3 = (EditText) findViewById(R.id.editText3);
answer4 = (EditText) findViewById(R.id.editText4);
answer5 = (EditText) findViewById(R.id.editText5);
answer6 = (EditText) findViewById(R.id.editText6);

    Should be:

    answers = new EditText[6];
answers[0] = (EditText) findViewById(R.id.editText1);
answers[1] = (EditText) findViewById(R.id.editText2);
answers[2] = (EditText) findViewById(R.id.editText3);
answers[3] = (EditText) findViewById(R.id.editText4);
answers[4] = (EditText) findViewById(R.id.editText5);
answers[5] = (EditText) findViewById(R.id.editText6);

    Otherwise you aren’t ever adding anything to the answers array, as has been stated. It seems to me that you’re thinking answer1 through answer6 are going into your answers array, unless you have those declared elsewhere that you haven’t posted. All 6 EditTexts in your answers array are currently null, which is causing your Exception.

    Also, something like this would be more concise:

    int[] editTexts = { R.id.editText1, R.id.editText2, R.id.editText3, 
    R.id.editText4, R.id.editText5, R.id.editText6 };

EditText[] answers = new EditText[editTexts.length];

for(int i = 0; i < answers.length; i++) {
    answers[i] = (EditText)findViewById(editTexts[i]);
}
