I have already prepared my side menu, but now I need to select an option to send me the corresponding activity. Then I leave my code:

public class cliente_inicio extends AppCompatActivity {


    private DrawerLayout drawerLayout;
    private LinearLayout mainLayout;
    private ListView menuLateral;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_cliente_inicio);

        ActionBar aBar = getSupportActionBar();
        aBar.setHomeButtonEnabled(true);
        aBar.setDisplayHomeAsUpEnabled(true);

        drawerLayout= (DrawerLayout)findViewById(R.id.drawerlayaout);
        mainLayout=(LinearLayout)findViewById(R.id.mainLayout);
        menuLateral=(ListView)findViewById(R.id.menuLateral);

        String[] opciones={"Catalogo","Paquetes","Galeria","Contacto","Iniciar Sesion"};
        ArrayAdapter<String> adp=new ArrayAdapter<String>(cliente_inicio.this, android.R.layout.simple_list_item_1,opciones);
        menuLateral.setAdapter(adp);

        menuLateral.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                String opcSeleccionado=(String) menuLateral.getAdapter().getItem(position);
                Toast.makeText(cliente_inicio.this, opcSeleccionado, Toast.LENGTH_SHORT).show();
            }
        });
    }
    public boolean onCreateOptionsMenu (Menu menu){
        getMenuInflater().inflate(R.menu.cliente_inicio,menu);
        return true;
    }
    public boolean onOptionsItemSelected(MenuItem item){
        int id = item.getItemId();

        if (id==android.R.id.home){
            if (drawerLayout.isDrawerOpen(menuLateral)){
                drawerLayout.closeDrawer(menuLateral);
            }else {
                drawerLayout.openDrawer(menuLateral);
            }
        }
        if (id==R.id.action_settings){
            return true;
        }
        return super.onOptionsItemSelected(item);
    }

}

I usually do it through Intent , in the onOptionsItemSelected method.

For example:

public boolean onOptionsItemSelected(MenuItem item) {
        int id = item.getItemId();

        if (id == R.id.action_settings) {
            Intent i = new Intent(this, ActivityQueSeLLamara.class);
            startActivity(i);
        }

        if (id == R.id.nav_otra) {
            Intent i = new Intent(this, ActivityOtra.class);
            startActivity(i);
        }

        return super.onOptionsItemSelected(item);
    }

Here,

In the if you have to ask for the id of the option that has been selected. In the example I used action_settings and another hypothetical id nav_otra which you will have to change for some valid option of your menu.
In Intent the value this will represent the current activity. You can also put it that way Intent i = new Intent(MainActivity.this, ActivityOtra.class); , assuming that the activity in which you have the drawer is MainActivity .
ActivityOtra.class and ActivityQueSeLLamara.class are fictitious names that you must change for the actual activitys you want to call in each menu option that you press.
I have not put this if in my answer: if (id==android.R.id.home){... because it does not concern the solution of the problem. I say this because it does not mean that you should delete that part in your method because I did not put it in the answer.
