我目前正在开发需要支持 Api10+ 的 Android 应用程序，我按照许多教程设置 appcompat 以管理创建操作栏。

链接如： https ://stackoverflow.com/a/21291156/2789106 http://developer.android.com/guide/topics/ui/actionbar.html

只有三件事我不能做。

  1. 当搜索打开时，搜索放大镜不会更改为我设置的可绘制对象。
  2. 我无法更改“返回”图标（主页向上按钮，左侧的徽标（它与我在创建时传递的图像不同drawerToggle））
  3. 单击键盘搜索时，我无法以编程方式关闭（折叠）操作视图。（调用collapseActionView()在 API 14 中实现）

这是我的代码： 

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

    // ActionBarDrawerToggle ties together the the proper interactions
    // between the sliding drawer and the action bar app icon

    mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);

    mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
            R.drawable.ic_navigation_drawer,
            R.string.navigation_drawer_open,
            R.string.navigation_drawer_close) {

        /** Called when a drawer has settled in a completely closed state. */
        public void onDrawerClosed(View view) {
            supportInvalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
        }

        /** Called when a drawer has settled in a completely open state. */
        public void onDrawerOpened(View drawerView) {
            supportInvalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
        }

    };

    // Set the drawer toggle as the DrawerListener
    mDrawerLayout.setDrawerListener(mDrawerToggle);

    // Restore app state if any
    if (savedInstanceState == null) {
        mLeftMenuContainer = (LinearLayout) findViewById(R.id.left_menu_container);
        mLeftMenuContainer.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View arg0, MotionEvent arg1) {
                // return TRUE to avoid tap on back view
                return true;
            }

        });
        mDrawerLayout.closeDrawer(mLeftMenuContainer);

    }

    // enable ActionBar app icon to behave as action to toggle nav drawer
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    getSupportActionBar().setHomeButtonEnabled(true);
    getSupportActionBar().setDisplayShowTitleEnabled(true);
    getSupportActionBar().setLogo(R.drawable.ic_action_bar_logo);

}

/* Called whenever we call supportInvalidateOptionsMenu() */
@Override
public boolean onPrepareOptionsMenu(Menu menu) {
    // If the nav drawer is open, hide action items related to the content
    // view
    if (mDrawerLayout != null && mLeftMenuContainer != null) {
        boolean drawerOpen = mDrawerLayout.isDrawerOpen(mLeftMenuContainer);
        for (int i = 0; i < menu.size(); i++) {
            menu.getItem(i).setVisible(!drawerOpen);
        }
    }

    return super.onPrepareOptionsMenu(menu);
}

@Override
protected void onPostCreate(Bundle savedInstanceState) {
    super.onPostCreate(savedInstanceState);
    // Sync the toggle state after onRestoreInstanceState has occurred.
    mDrawerToggle.syncState();
}

@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);
    mDrawerToggle.onConfigurationChanged(newConfig);  
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {

    mMenu = menu;
    // Inflate the menu; this adds items to the action bar if it is present.
    // enable ActionBar app icon to behave as action to toggle nav drawer
    getMenuInflater().inflate(R.menu.main, menu);

    MenuItem searchItem = menu.findItem(R.id.action_bar_search);
    final SearchView searchView = (SearchView) MenuItemCompat.getActionView(searchItem);

    SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
    SearchableInfo info = searchManager.getSearchableInfo(getComponentName());

    searchView.setSearchableInfo(info);  

    AutoCompleteTextView searchText = (AutoCompleteTextView) searchView.findViewById(android.support.v7.appcompat.R.id.search_src_text);
    searchText.setHintTextColor(getResources().getColor(R.color.color_action_bar_search_text));
    searchText.setTextColor(getResources().getColor(R.color.color_action_bar_search_text));

    searchView.setIconifiedByDefault(true);

    // Getting the 'search_plate' LinearLayout.
    View searchPlate = searchView.findViewById(android.support.v7.appcompat.R.id.search_plate);
    // Setting background of 'search_plate' to personal defined drawable.
    if (searchPlate != null) {
        searchPlate
            .setBackgroundResource(R.drawable.texfield_search_view_theme);
    }

    // Set search view clear icon
    ImageView searchIconClearView = (ImageView) searchView
            .findViewById(android.support.v7.appcompat.R.id.search_close_btn);
    if (searchIconClearView != null) {
        Log.v(LOG_TAG, "Should Change Clear Icon here");

        searchIconClearView
            .setImageResource(R.drawable.ic_action_bar_clear_search);

    }

    // Set search view Magnifier icon
    ImageView searchIcon = (ImageView) searchView.findViewById(android.support.v7.appcompat.R.id.search_mag_icon);
    if (searchIcon != null) {
        Log.v(LOG_TAG, "Should Change Search Icon here");
        searchIcon.setImageResource(R.drawable.ic_action_bar_back);
    }

    // Set on click to open a fragment, not a activity
    final SearchView.OnQueryTextListener queryTextListener = new SearchView.OnQueryTextListener() {
        @Override
        public boolean onQueryTextChange(String newText) {
            // Do something
            return true;
        }

        @Override
        public boolean onQueryTextSubmit(String query) {
            Log.v(LOG_TAG, "Performed search with: " + query);
            searchView.clearFocus();
            return true;
        }
    };

    searchView.setOnQueryTextListener(queryTextListener);

    MenuItemCompat.setOnActionExpandListener(searchItem, new OnActionExpandListener() {

        @Override
        public boolean onMenuItemActionCollapse(MenuItem arg0) {
            mMenu.findItem(R.id.action_bar_cart).setVisible(true);
            return true;
        }

        @Override
        public boolean onMenuItemActionExpand(MenuItem arg0) {
            getSupportActionBar().setIcon(R.drawable.ic_action_bar_logo);
            mMenu.findItem(R.id.action_bar_cart).setVisible(false);
            return true;
        }


    });

    return super.onCreateOptionsMenu(menu);
}

如果我做错了什么，有人可以告诉我吗？

我设法解决了问题 1 和 2：

您需要做的是在您的主题中定义 homeUpIcon。因此，如果您像我一样支持 API 10：

<style name="Theme.MyTheme" parent="@style/Theme.AppCompat.Light">
    <item name="searchViewSearchIcon">@drawable/your_search_icon</item>

    <!-- API 13- Support -->
    <item name="homeAsUpIndicator">@drawable/your_back_icon</item> 

    <!-- API 14+  -->
    <item name="android:homeAsUpIndicator">@drawable/your_back_icon</item> 

</style>

在
ActionBarSherlock 中找到：更改 homeAsUpIndicator 不起作用
和 更改 searchview 小部件的背景可绘制对象

最重要的问题仍然悬而未决，如果有人知道答案，请在此处发布！

尝试这个：

   public boolean onQueryTextSubmit(String query) {
        MenuItemCompat.collapseActionView(searchItem);
        return false;
    }
