Question

我正在关注android search interface并开发了以下代码。

能够在其他活动中看到搜索图标。
点击搜索图标获取搜索视图。
搜索和点击输入搜索活动未被调用或调用
searchManager.getSearchableInfo(getComponentName())正在返回null

我的代码低于

SearchableActivity.java

public class SearchableActivity extends ListActivity {
    public static String ACTIVITY = "activity";
    final private String TAG = Common.TAG + getClass().getSimpleName();

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        Log.d(TAG, "onCreate");
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_searchable);
        // Get the intent, verify the action and get the query
        handleIntent(getIntent());
    }

    @Override
    protected void onNewIntent(Intent intent) {
        Log.d(TAG, "onNewIntent");
        handleIntent(intent);
    }

    private void handleIntent(Intent intent) {
        Log.d(TAG, "handleIntent");
        if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
            String query = intent.getStringExtra(SearchManager.QUERY);
            doMySearch(query);
        }

        Bundle appData = getIntent().getBundleExtra(SearchManager.APP_DATA);
        if (appData != null) {
            boolean jargon = appData.getBoolean(SearchableActivity.ACTIVITY);
            Log.i(TAG, "jargon" + jargon);
        }
    }
    public void doMySearch(String query) {
    }
}

将以下代码用于onCreateOptionsMenu。用文件名替换菜单文件名和菜单项名称

    @Override
     public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.menu_main, menu);

    MenuItem search_item = menu.findItem(R.id.mi_search);

    SearchView searchView = (SearchView) search_item.getActionView();
    searchView.setFocusable(false);
    searchView.setQueryHint("Search");
    searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {


        @Override
        public boolean onQueryTextSubmit(String s) {

            keyword = s.toUpperCase();
            //place your search code here              
            return false;
        }

        @Override
        public boolean onQueryTextChange(String s) {
            return false;
        }
    });


    return true;
}
