My app keeps crashing when I press the button to return to the activity from a dialog

The issue stems from the OK Button clickable. the moment I click on the button (in both cases of text and numbers being present/absent in the EditTexts) the app stops working. I can't seem to find where this error is coming from. I've double-checked variables being initialized and the problem doesn't seem to stem from there. Can anyone help out?

The code is below:

public void mInput(View view){
     final Dialog dialogManualInput = new Dialog(this);
     dialogManualInput.setContentView(R.layout.dialog_A);
     dialogManualInput.setTitle("Title");

     et1 = (EditText) dialogManualInput.findViewById(R.id.item);
     et2 = (EditText) dialogManualInput.findViewById(R.id.price);
     et3 = (EditText) dialogManualInput.findViewById(R.id.quantity);

     m_adapter = new ArrayAdapter<String>(this,R.layout.activity_A,m_listItems);
     checkoutList = (ListView)findViewById(R.id.listview);
     checkoutList.setAdapter(m_adapter);

     dialogManualInput.show();

     Button okButton = (Button) dialogManualInput.findViewById(R.id.ok);
     okButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

        String input_1 = et1.getText().toString();
        String input_2 = et2.getText().toString();
        String input_3 = et3.getText().toString();
        int int_1 = Integer.valueOf(et3);
        int int_2 = Integer.valueOf(et2);
        String input = "("+et2+")  " + et1 +"   "+ (int_1*int_2);
        if((null!=input_1)&&(null!=input_2)&&(null!=input_3)){
           m_listItems.add(input);
           m_adapter.notifyDataSetChanged();
        }
        dialogManualInput.dismiss();
      }
  });
}

Here is the logcat:

EDIT 1:

As it seems from Logcat problem is 

 m_adapter = new ArrayAdapter<String>(this,R.layout.activity_A,m_listItems);
 checkoutList = (ListView)findViewById(R.id.listview);
 checkoutList.setAdapter(m_adapter);

You are providing m_listItems(I don't know what this is ) and its is looking for an id of a TextView pass a textView's ID in 

 ArrayAdapter<String>(this,R.layout.activity_A,m_listItems);

Some thing like 

 ArrayAdapter<String>(this,R.layout.activity_A,R.id.textView01);

Probable Errors

what is this doing you directly putting your edittext to be concatenated with string what it is expected to here may be it should be int_1, or et1.getText() i.e. input_1

    String input = "("+et2+")  " + et1 +"   "+ (int_1*int_2);

If any not initialized as usual NPE for et1, et2, et3 OR

Parsing Exception in these (if you not fill the editText then it must throw exception) 

    int int_1 = Integer.valueOf(et3);
    int int_2 = Integer.valueOf(et2);

The problem could be with your layout. Show us this XML file "R.layout.activity_A" or take a look at it.
