如何关闭导航抽屉以使用返回主页图标按钮? [英] How can I dismiss the Navigation Drawer to use the Back-home-icon button?

问题描述

我也在使用带有搜索栏的操作栏，我需要像返回按钮一样使用操作栏图标:

I'm using the action bar with search bar too, and I need to use the ActionBar ico like a Back button:

但我也在使用抽屉式导航...如何关闭/隐藏/禁用导航抽屉菜单以使用后退按钮?

But I'm using the navigation drawer too... How can I dismiss/hide/disable the Navigation Drawer menu to use the back button?

我的动作条码:

@Override
public boolean onCreateOptionsMenu(Menu menu){
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.main, menu);

    this.getSupportActionBar().setDisplayShowCustomEnabled(true);
    this.getSupportActionBar().setDisplayShowTitleEnabled(false);

    this.getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    this.getSupportActionBar().setHomeButtonEnabled(true);

    LayoutInflater inflator = (LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View v;

    if(!searchView){
        v = inflator.inflate(R.layout.action_textview, null);
        ((TextView) v.findViewById(R.id.titleText)).setText(actionTitle);
        menu.getItem(0).setVisible(true);
        menu.getItem(2).setVisible(true);
        mainMenu = menu;

    }else{
        v = inflator.inflate(R.layout.action_searchview, null);
        actionSearch = (EditText) v.findViewById(R.id.searchText);
        actionSearch.setOnEditorActionListener(new OnEditorActionListener() {
            @Override
            public boolean onEditorAction(TextView view, int actionId, KeyEvent event) {
                int result = actionId & EditorInfo.IME_MASK_ACTION;
                switch(result) {
                case EditorInfo.IME_ACTION_DONE:
                case EditorInfo.IME_ACTION_NEXT:
                case EditorInfo.IME_ACTION_GO:
                case 0:
                    ((InputMethodManager)getSystemService(INPUT_METHOD_SERVICE)).hideSoftInputFromWindow(actionSearch.getWindowToken(), 0);
                    String temp = actionSearch.getText().toString();
                    searchFor(temp);
                    break;
                }
                return true;
            }
        });
        actionSearch.requestFocus();
        menu.getItem(0).setVisible(false);
        menu.getItem(2).setVisible(false);
    }
    this.getSupportActionBar().setCustomView(v);        

    return super.onCreateOptionsMenu(menu);
}

代码帮助:

1. My Title 是一个只有 TextView 的自定义视图，用于自定义字体颜色和大小；(action_textview)
2. 我的 SearchBar 使用只有一个 EditText 的自定义视图；(action_searchview)

推荐答案

从ActionBarDrawerToggle可以使用setDrawerIndicatorEnabled(Boolean enable)方法.或者，您可以设置 ActionBar 显示选项.特别是标志 DISPLAY_HOME_AS_UP.链接到文档

From ActionBarDrawerToggle you can use the method setDrawerIndicatorEnabled(Boolean enable). Alternatively, you can set the ActionBar Display options. Specifically the flag DISPLAY_HOME_AS_UP. Link to docs

然后像往常一样处理点击事件.

Then handle the click event as usual.
