Hide one activity and show another activity

I've created an item - activity2 in menu(in res>menu>main.xml) and I want when the user will click the activity2, activity1 will hide (which is already running) and activity2 will show. And also when user press back the activity2 will hide and activity1 will visible to the user. How to do this? Please explain.

You can get onclick event of menu item in onOptionsItemSelected.

public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case R.id.activity2:
            // start your activity2
            startActivity(new Intent(MainActivity.this, Activity2.class));
            // no need to finish MainActivity 

        default:
            return super.onOptionsItemSelected(item);
    }
}
  • Now the MainActivity is not destroyed so if u press back on Activity2 then MainActivity will be displayed.

You need to use onPrepareOptionMenu method in your Activity where in you can set visibility using setVisible. you can refer below code as an example:

public boolean onPrepareOptionsMenu(Menu menu)
{
    MenuItem register = menu.findItem(R.id.menuregistrar);      
    if(userRegistered) 
    {           
        register.setVisible(false);
    }
    else
    {
        register.setVisible(true);
    }
    return true;
}

You should use menuItem.setVisible(false); to hide menuItem tha maintain its visibility,

EX :

@Override
    public boolean onPrepareOptionsMenu(Menu menu) {
        MenuItem menuItem = menu.findItem(R.id.icon_websearch);//your icon
        menuItem.setVisible(false);
        return super.onPrepareOptionsMenu(menu);
    }
