如何在Action Bar Sherlock中实现搜索小部件？

Question

我试图让搜索框在Action Bar Sherlock上运行.

这是我的PreLocationActivity:

    @ContentView(R.layout.search)
    public class PreLocationActivity extends RoboSherlockActivity {

        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            //setContentView(R.layout.map_layout);
        } 

        @Override
        public boolean onCreateOptionsMenu(Menu menu) {
            //Used to put dark icons on light action bar
             menu.add("Search")
             .setIcon(R.drawable.ic_search_inverse)
             .setActionView(R.layout.collapsible_edittext)
             .setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS | MenuItem.SHOW_AS_ACTION_COLLAPSE_ACTION_VIEW);
                return true;
        }

        @Override
        public boolean onSearchRequested() {
            return super.onSearchRequested();
        }
    }

这是我的SearchableActivity:

@ContentView(R.layout.search)
public class SearchableActivity extends RoboSherlockFragmentActivity {

    @InjectView(R.id.addressListView) ListView addressView;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        // Get the intent, verify the action and get the query
        Intent intent = getIntent();
        if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
          String query = intent.getStringExtra(SearchManager.QUERY);
          doGeoSearch(query);
        }
}

    public void doGeoSearch(String query){
        Geocoder geocoder;
        ArrayList<Address> addresses;
        ArrayList<String> address = new ArrayList<String>() ;
        geocoder = new Geocoder(this, Locale.getDefault());
        try {
            addresses = (ArrayList<Address>) geocoder.getFromLocationName(query, 6);
            Log.d("Address",String.valueOf(addresses));
            for(int i = 0;i<addresses.size();i++)
            {
            String addr = new String();
            addr.concat(addresses.get(i).getAddressLine(0));
            addr.concat(addresses.get(i).getAddressLine(1));
            addr = addresses.get(i).getAddressLine(0) + addresses.get(i).getLocality() + addresses.get(i).getAdminArea();
            //addr.concat(addresses.get(i).getAddressLine(2));
            Log.d("addr",addr);
            address.add(addr);

            }

            SearchAddressAdapater addressList = new SearchAddressAdapater(getApplicationContext(),R.layout.search_list,addresses, SearchableActivity.this);
            addressView.setAdapter(addressList);
            //ListView addressListView = new ListView();
        } catch (IOException e) {
                //Handle exception
        }
    }

根本没有成功.就像在,当我在Prelocation Activity上输入内容并按回车键时,没有搜索任何内容.我是否必须将其视为一个EditText并为其编写一个文本监听器,然后调用它geoCoder并获取位置或者是否有更聪明的方法来实现它？

Android支持库(v4 + v7):

支持库v7: http ://developer.android.com/tools/support-library/features.html#v7-appcompat

谷歌现在支持ActionBar与Android 2.1(API 7)的兼容性.

由于方法名称相同和/或非常相似,因此很容易进行转换.

使用资源添加支持库: http ://developer.android.com/tools/support-library/setup.html#libs-with-res

您的清单:AndroidManifest.xml

<uses-sdk
  android:minSdkVersion="7"
  android:targetSdkVersion="17" />

您的菜单:menu.xml

<item
    android:id="@+id/menu_search"
    android:actionViewClass="android.support.v7.widget.SearchView"
    android:icon="@drawable/ic_action_search"
    android:showAsAction="ifRoom|collapseActionView"
    android:title="Search"/>

ActionBarSherlock [不建议使用,请使用appcompat]:

以下是如何在Android中使用ActionBarSherlock的标准SearchView和SearchManager!我使用此代码并正常工作.我在Android 2.3(API 10) - Android 4.3(API 18)上测试了这个.

伟大的教程和文档:

http://developer.samsung.com/android/technical-docs/UI-unification-with-older-Android-versions-using-ActionBarSherlock

记住:

使用ActionBarSherlock进行自定义搜索(最低API 7)

SearchView with ActionBarSherlock(最低API 8)

您的菜单:menu.xml

<item
    android:id="@+id/menu_search"
    android:actionViewClass="com.actionbarsherlock.widget.SearchView"
    android:icon="@drawable/ic_action_search"
    android:showAsAction="ifRoom|collapseActionView"
    android:title="Search"/>

对彼此而言:

您的活动:MainActivity.java

public boolean onCreateOptionsMenu(Menu menu) 
{
        getSupportMenuInflater().inflate(R.menu.menu, menu);

        SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
        SearchView searchView = (SearchView) menu.findItem(R.id.menu_search).getActionView();
        if (null != searchView )
        {
            searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
            searchView.setIconifiedByDefault(false);   
        }

        SearchView.OnQueryTextListener queryTextListener = new SearchView.OnQueryTextListener() 
        {
            public boolean onQueryTextChange(String newText) 
            {
                // this is your adapter that will be filtered
                adapter.getFilter().filter(newText);
                return true;
            }

            public boolean onQueryTextSubmit(String query) 
            {
                // this is your adapter that will be filtered
                adapter.getFilter().filter(query);
                return true;
            }
        };
        searchView.setOnQueryTextListener(queryTextListener);

        return super.onCreateOptionsMenu(menu);
    }

private EditText search;

public boolean onCreateOptionsMenu(com.actionbarsherlock.view.Menu menu)
{
    menu.add(0, 1, 1, R.string.menu_search).setIcon(R.drawable.ic_action_search).setActionView(R.layout.action_search).setShowAsAction(MenuItem.SHOW_AS_ACTION_IF_ROOM | MenuItem.SHOW_AS_ACTION_COLLAPSE_ACTION_VIEW);
    return super.onCreateOptionsMenu(menu);
}

@Override
public boolean onOptionsItemSelected(com.actionbarsherlock.view.MenuItem item)
{
    switch (item.getItemId())
    {
        case 1:
        search = (EditText) item.getActionView();
        search.addTextChangedListener(filterTextWatcher);
        search.requestFocus();
        InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);
    }
}

private TextWatcher filterTextWatcher = new TextWatcher()
{
    public void afterTextChanged(Editable s)
    {
    }

    public void beforeTextChanged(CharSequence s, int start, int count, int after)
    {
    }

    public void onTextChanged(CharSequence s, int start, int before, int count)
    {
        // your search logic here
    }
};
