Answer 1

You have wrongly initialized your TextView As you have added TextView in your layout and you are trying to initialize it with LinearLayout which is wrong.

Change the LinearLayout with TextView in your onCreate() as below :

 someLayout = (TextView) findViewById(R.id.state2); 

Why are you inflating your layout two times in your code ? I do not understand why are you doing so. But i am providing the code with some relevant code try with my code.

public class MainActivity extends Activity {
private LayoutInflater inflater;
private TextView someLayout;

@Override
protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
       setContentView(R.layout.activity_main);
       someLayout = (TextView) findViewById(R.id.state2); //layout present in      activity_main
      // inflater = (LayoutInflater)getSystemService(LAYOUT_INFLATER_SERVICE);
     runNextTask();

 }
 public void runNextTask(){
       //  LinearLayout mInflatedLayout = (LinearLayout)               inflater.inflate(R.layout.activity_main, null);
      @SuppressWarnings("unused")
    final TrackerInfo newInfo = new TrackerInfo();
    //set up for model selection
   // TextView modelTextview = (TextView)mInflatedLayout.findViewById(R.id.state2); 
    //someLayout.addView(mInflatedLayout);                   
    someLayout.setOnClickListener(new OnClickListener() {
       @Override
       public void onClick(View v) {

       }
    });
 }

FYI You can not add any layout in TextView as its View not a Layout and in your code i have seen that you are trying to add Layout into View which is wrong.
