android activity onSearchRequested()

1.manifest中声明处理搜索的Activity（仅此声明后就可以调用）

<meta-data android:name="android.app.default_searchable" android:value=".OnSearchAppsList" />

2.Activity定义

<activity android:name=".OnSearchAppsList"android:configChanges="orientation|keyboardHidden|navigation"android:label="@string/Market"><intent-filter><action android:name="android.intent.action.SEARCH" /><category android:name="android.intent.category.DEFAULT" /></intent-filter><meta-data android:name="android.app.searchable" android:resource="@xml/searchable" /></activity>

3.searchable.xml定义

<?xml version="1.0" encoding="utf-8"?><searchable xmlns:android="http://schemas.android.com/apk/res/android"android:label="@string/search_label"android:hint="@string/search_hint" />

4.调用 Search功能

　　onSearchRequested();
5.截获参数
　　getIntent().getStringExtra(SearchManager.QUERY);

这后即可以随意处理搜索请求了。

具体使用时可以结合Activity的showDialog方法:

private static final int DIALOG_SEARCH_TEXT = 1;

@Overridepublic boolean onSearchRequested() {       showDialog(DIALOG_SEARCH_TEXT);       return false;}

 @Override    protected Dialog onCreateDialog(int id) {        switch (id) {            case DIALOG_SEARCH_TEXT:                LayoutInflater factory = LayoutInflater.from(this);                final View searchView = factory.inflate(R.layout.dialog_search_article, null);                final EditText editText = (EditText)searchView.findViewById(R.id.search_query);                editText.setOnEditorActionListener(new TextView.OnEditorActionListener() {                    @Override                    public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {                        if (actionId == EditorInfo.IME_ACTION_SEARCH                                || actionId == EditorInfo.IME_NULL) {                            InputMethodManager inputMethodManager = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);                            inputMethodManager.hideSoftInputFromWindow(                                    editText.getApplicationWindowToken(),                                    InputMethodManager.HIDE_NOT_ALWAYS);                            dismissDialog(DIALOG_SEARCH_TEXT);                            doSearch(editText);                            return true;                        }                        return false;                    }                });                return new AlertDialog.Builder(this)                        .setTitle(R.string.search_article_title)                        .setView(searchView)                        .setPositiveButton(R.string.search_article_ok,                                new DialogInterface.OnClickListener() {                                    @Override                                    public void onClick(DialogInterface dialog, int whichButton) {                                        doSearch(editText);                                    }                                })                        .setNegativeButton(R.string.search_article_cancel,                                new DialogInterface.OnClickListener() {                                    @Override                                    public void onClick(DialogInterface dialog, int whichButton) {                                    }                                }).create();        }        return null;    }
