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;

@Override

public 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;

    }
