Accessing variables from another class Android Studio
<p>I'm new to android development and I'm wondering how this can be done. I have a class named ListDeadlines with variables such as </p>

<pre><code>public ArrayList&lt;String&gt; arrayList;
public ArrayAdapter&lt;String&gt; adapter;
public EditText txtInput;
</code></pre>

<p>I want to be able to access these variables in a different class. I have tried it like this, however I get the fallowing error on my <code>lst.txtInput lst.arrayList lst.adapter</code> saying <code>Variable 'lst' is accessed from within inner class, needs to be declared final.</code> Anyone got any ideas on how to access variables in another class.</p>

<pre><code>    ListDeadlines lst= new ListDeadlines();
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);

    lst.txtInput=(EditText)findViewById(R.id.txtinput);
    Button btAdd=(Button)findViewById(R.id.btnAdd);
    btAdd.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            String newItem = lst.txtInput.getText().toString();
           lst.arrayList.add(newItem);
            lst.adapter.notifyDataSetChanged();
            ;
        }
    });
</code></pre>
