In mainActivity I have method "toast1"

public class MainActivity extends Activity {

    //some imports
    public TextView txtv;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    //some code
    }
    //some code
    public void toast1(String txtxt) {
        txtv = (TextView) findViewById(R.id.txtzz);
        txtv.setText(txtxt);
    }

But when toast1 method is launched, the exception is thrown:

04-18 21:16:35.185    3198-3198/com.AleXMan.democracy.standart E/InputEventReceiver﹕ Exception dispatching input event.

                        at android.app.Activity.findViewById(Activity.java:1888)
                        at com.AleXMan.democracy.standart.MainActivity.toast1(MainActivity.java:48)
                        ...other

Does anyone know how to fix this?

check and make sure you have the correct id for that textview – tyczj Apr 18 '14 at 18:28
activity_main xml please. – Sush Apr 18 '14 at 18:37
The activity main is very long, about 362 lines. The text view is located at the bottom. – user2186218 Apr 18 '14 at 18:43
are u sure your activity layout contains that view ? – r4jiv007 Apr 18 '14 at 18:46
