           2.Event tab
           3.Groupchat tab  and

3 menus in my layout namely,

我的布局中有3个菜单,

           1.Dropdown menu
           2.create occasion menu
           3.settings menu 

Atpresent all my tabs display all three menus,But i need to display specific menu on specific tab when it is onclick,for example

目前我的所有标签显示所有三个菜单,但我需要在特定标签上显示特定菜单,例如

           1.when ontap "Invitation tab" just show "settings menu" only.
           2.when ontap "Event tab" only shows"create occasion and settings menus"
           3.similarly when ontap "Groupchat tab" only shows"Dropdown and settings menus".

You can do by this

你可以做到这一点

    public class MainActivity extends Activity {

 ToggleButton btn1, btn2, btn3;
 Menu myMenu;

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

  btn1 = (ToggleButton)findViewById(R.id.option1);
  btn2 = (ToggleButton)findViewById(R.id.option2);
  btn3 = (ToggleButton)findViewById(R.id.option3);

  btn1.setOnCheckedChangeListener(btnOnCheckedChangeListener);
  btn2.setOnCheckedChangeListener(btnOnCheckedChangeListener);
  btn3.setOnCheckedChangeListener(btnOnCheckedChangeListener);
 }

 OnCheckedChangeListener btnOnCheckedChangeListener =
  new OnCheckedChangeListener(){

   @Override
   public void onCheckedChanged(CompoundButton buttonView, 
     boolean isChecked) {
    if(myMenu != null){
     if(buttonView==btn1){

      myMenu.findItem(R.id.menuopt1)
       .setVisible(isChecked);
      myMenu.findItem(R.id.menuopt1)
       .setEnabled(isChecked);
     }else if(buttonView==btn2){
      myMenu.findItem(R.id.menuopt2)
       .setVisible(isChecked);
      myMenu.findItem(R.id.menuopt2)
       .setEnabled(isChecked);
     }else if(buttonView==btn3){
      myMenu.findItem(R.id.menuopt3)
       .setVisible(isChecked);
      myMenu.findItem(R.id.menuopt3)
       .setEnabled(isChecked);
     }
    }

   }};

 @Override
 public boolean onCreateOptionsMenu(Menu menu) {
  getMenuInflater().inflate(R.menu.main, menu);
  myMenu = menu;
  return true;
 }

 @Override
 public boolean onOptionsItemSelected(MenuItem item) {
  switch(item.getItemId()){
  case R.id.menuopt1:
   Toast.makeText(MainActivity.this, 
    "menuopt1", 
    Toast.LENGTH_SHORT).show();
   break;
  case R.id.menuopt2:
   Toast.makeText(MainActivity.this, 
    "menuopt2", 
    Toast.LENGTH_SHORT).show();
   break;
  case R.id.menuopt3:
   Toast.makeText(MainActivity.this, 
    "menuopt3", 
    Toast.LENGTH_SHORT).show();
   break;
  }
  return super.onOptionsItemSelected(item);
 }

}
