Fragment 菜单

必须在fragment初始化时

  protected void initToolbar(View view) {
   
    //fragment显示toolbar
    setHasOptionsMenu(true);
    if (mToolbar != null) {
        ((AppCompatActivity) mActivity).setSupportActionBar(mToolbar);
        mToolbar.setTitle("");
    }
}

创建菜单和菜单的点击事件

  @Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    if (!hasToolbar()) {
        return;
    }
    menu.clear();
    if (menuResId != 0 || !TextUtils.isEmpty(menuStr)) {
        inflater.inflate(R.menu.menu_toolbar, menu);
    }
    super.onCreateOptionsMenu(menu, inflater);
}


@Override
public void onPrepareOptionsMenu(Menu menu) {
    if (!hasToolbar() || mToolbar == null) {
        return;
    }
    MenuItem menuItem = menu.findItem(R.id.menu_1);
    if (menuResId != 0) {
        menuItem.setIcon(menuResId);
    }
    if (!TextUtils.isEmpty(menuStr)) {
        menuItem.setTitle(menuStr);
    }
    mToolbar.setOnMenuItemClickListener(new Toolbar.OnMenuItemClickListener() {
        @Override
        public boolean onMenuItemClick(MenuItem item) {
            if (item.getItemId() == R.id.menu_1 && onClickListenerTopRight != null) {
                onClickListenerTopRight.onClick();
                return true;
            }
            return false;
        }
    });
    super.onPrepareOptionsMenu(menu);
}
