     toolbar = (Toolbar) findViewById(R.id.toolbar); 
     setSupportActionBar(toolbar); 
     getSupportActionBar().setDisplayShowTitleEnabled(false); 
     Spinner navigationSpinner = new Spinner(getSupportActionBar().getThemedContext()); 
     ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, category); 
     navigationSpinner.setAdapter(adapter); 
     toolbar.addView(navigationSpinner, 0); 

     navigationSpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() { 
      @Override 
      public void onItemSelected(AdapterView<?> parent, View view, int position, long id) { 
       Toast.makeText(MenuActivity.this, 
         "you selected: " + category.get(position), 
         Toast.LENGTH_SHORT).show(); 
      } 

      @Override 
      public void onNothingSelected(AdapterView<?> parent) { 

      } 
     }); 
    } 


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

我将使用的OnCreate选项菜单工具栏，如果是的话，我怎么能，使用T他，对不起，如果，如果有任何意见请只需要加一个注释

你只需要''override' onOptionsItemSelected' –

覆盖的方法onOptionsItemSelected

这样的：

@Override 
public boolean onOptionsItemSelected(MenuItem item) { 
    // Handle item selection 
    switch (item.getItemId()) { 
     case R.id.searchicon: 
      //do something 
      return true; 
     case R.id.listicon: 
       //do something 
      return true; 
     case R.id.gridicon: 
       //do something 
      return true; 
     default: 
      return super.onOptionsItemSelected(item); 
    } 
}

处理click事件在menu发生任何事情不清楚，你必须覆盖的Activity的onOptionsItemSelected方法，像这样：

@Override 
public boolean onOptionsItemSelected(MenuItem item) { 
    switch(item.getItemId()) { 
     case R.id.searchicon: 
      // ... 
      return true; 
     case R.id.listicon: 
      // ... 
      return true; 
     case R.id.gridicon: 
      // ... 
      return true; 
    } 

    return super.onOptionsItemSelected(item); 
}

只是覆盖的方法：

@Override 
    public boolean onOptionsItemSelected(MenuItem item) { 
     switch (item.getItemId()) { 
      case R.id.action_reset: 
       // your action 
       break; 
     } 
     return super.onOptionsItemSelected(item); 
    }
