在片段中添加onOptionsItemSelected调用 [英] Add onOptionsItemSelected calling in Fragment

问题描述

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();

    //noinspection SimplifiableIfStatement
    if (id == R.id.action_filter) {
        FragmentManager fm = getSupportFragmentManager();
        if (userType.equals("İş Arayan"))
            filterDialogTitle = "İş İlanları Filtre";
        else if (userType.equals("Hizmet Arayan"))
            filterDialogTitle = "Hizmet İlanları Filtre";
        FilterDialogFragment editNameDialogFragment = FilterDialogFragment.newInstance(filterDialogTitle);
        editNameDialogFragment.show(fm, "fragment_edit_name");
        return true;
    }

    return super.onOptionsItemSelected(item);
}

我在Fragment中添加了，但是我没有打电话，如果我在MainActivity中添加，它可以工作，但是我想在Fragment中调用.我该怎么办?

I added in Fragment, but i didn' t called, if i add in MainActivity, it works but i want call in Fragment. How can i do this ?

推荐答案

在 Fragment 中，您必须调用setHasOptionsMenu(true)

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setHasOptionsMenu(true);
    ...
}

然后假设您必须处理menu_item_to_handle_in_fragment项目单击

Then suppose you have to handle menu_item_to_handle_in_fragment item click

对于片段类

For Fragment class

  @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {

        case R.id.menu_item_to_handle_in_fragment:
            // Do onlick on menu action here
            return true;
        }
    return false;
}

对于活动类

For Activity class

 @Override
        public boolean onOptionsItemSelected(MenuItem item) {
            switch (item.getItemId()) {

            case R.id.menu_item_to_handle_in_fragment:
                return false;
            }
        return false;
    }
