how can I make 3 diffrent statement using 2 if condition in android studio

public class MainActivity extends AppCompatActivity {
DatabaseReference databaseHistory;
HistoryTremor historyTremor;
private int seconds = 0;
private boolean startRun;

TextView txtStatus2, txtTanggal, txtDurasi;
ListView lsvHistory1;

@Override

    txtStatus2 = (TextView) findViewById(R.id.txtStatus2);
    txtTanggal = (TextView) findViewById(R.id.txtTanggal);
    txtDurasi = (TextView) findViewById(R.id.txtDurasi);
    lsvHistory1 = (ListView) findViewById(R.id.lsvHistory1);
    textClock = (TextClock) findViewById(R.id.textClock);
    btnHistory = (Button) findViewById(R.id.btnHistory);
    databaseHistory = FirebaseDatabase.getInstance().getReference("HistoryTremor");

    startMqtt();


    if (savedInstanceState != null) {
        seconds = savedInstanceState.getInt("seconds");
        startRun = savedInstanceState.getBoolean("startRun");
    }
    txtTanggal.setText(currentDateTimeString);
    Timer();

    ListElementsArrayList = new ArrayList<String>(Arrays.asList(ListElements));

    adapter = new ArrayAdapter<String>(MainActivity.this,
            android.R.layout.simple_list_item_1,

hay guys, I make some simple Internet of Things using android as my front end project I have some trouble in if statement (I think)

I do have 2 condition for my project
