我正在实施Action Bar。我想在Action Bar SearchView的搜索字段区域中使用2个按钮,例如Flipkart app。

Flipkart app have two buttons in SearchView

与上面的截图一样,我想要2个按钮,第一个用于语音搜索,另一个用于条形码扫描,当点击搜索图标并出现SearchView Actionbar时。我可以使用搜索图标实现actionbar serahcview。但我有点困惑为什么语音搜索没有出现在我的应用程序中。看看我的源代码。

public class MainActivity extends Activity {

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


    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.main, menu);

        SearchView searchView = (SearchView) menu.findItem(R.id.action_search).getActionView();

        setSearchTextColour(searchView);
        setCloseSearchIcon(searchView);

        return super.onCreateOptionsMenu(menu);
    }

    @Override
    public boolean onPrepareOptionsMenu(Menu menu) {
        return super.onPrepareOptionsMenu(menu);
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {

        switch(item.getItemId()) {
        case R.id.action_search:

            return true;
        default:
            return super.onOptionsItemSelected(item);
        }
    }

    private void setSearchTextColour(SearchView searchView) {
        int searchPlateId = searchView.getContext().getResources().getIdentifier("android:id/search_src_text", null, null);
        EditText searchPlate = (EditText) searchView.findViewById(searchPlateId);
        searchPlate.setTextColor(getResources().getColor(R.color.novoda_blue));
//        searchPlate.setBackgroundResource(R.drawable.edit_text_holo_light);
        searchPlate.setImeOptions(EditorInfo.IME_ACTION_SEARCH);
    } 

 private void setCloseSearchIcon(SearchView searchView) {
        try {
            Field searchField = SearchView.class.getDeclaredField("mCloseButton");
            searchField.setAccessible(true);
            ImageView closeBtn = (ImageView) searchField.get(searchView);
            closeBtn.setImageResource(R.drawable.action_cancel);

            searchField = SearchView.class.getDeclaredField("mVoiceButton");
            searchField.setAccessible(true);
            ImageView voiceBtn = (ImageView) searchField.get(searchView);
            voiceBtn.setImageResource(R.drawable.ic_launcher);

        } catch (NoSuchFieldException e) {
            Log.e("SearchView", e.getMessage(), e);
        } catch (IllegalAccessException e) {
            Log.e("SearchView", e.getMessage(), e);
        }
    }

我从上面的代码中获得的屏幕截图:

首先,您应该阅读this

使用searchview小部件进行活动的AndroidManifest.xml(必须使用singleTop,请阅读上面的链接):

<activity android:name=".activities.MainActivity" 
    android:configChanges="orientation|screenSize" 
    android:launchMode="singleTop" >
    <meta-data
        android:name="android.app.searchable"
        android:resource="@xml/searchable" />
    <intent-filter>
        <action android:name="android.intent.action.SEARCH" />
    </intent-filter>
</activity>

使用以下方式创建 ... / res / xml / searchable.xml

<searchable xmlns:android="http://schemas.android.com/apk/res/android"
    android:label="@string/app_name"
    android:hint="@string/hint"
    android:voiceSearchMode="showVoiceSearchButton|launchRecognizer"/>

修改onCreateOptionsMenu(最后两行是重要的)

public boolean onCreateOptionsMenu(Menu menu) {
    this.menu = menu;
    MenuInflater menuInflater = getMenuInflater();
    menuInflater.inflate(R.menu.main_action_bar_menu, menu);

    MenuItem searchItem = menu.findItem(R.id.action_search);
    searchView = (SearchView) searchItem.getActionView();
    searchView.setQueryHint(getResources().getString(R.string.hint));

    SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
    searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
}

最后覆盖 onNewIntent()

@Override
protected void onNewIntent(Intent intent) {
    if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
        String query = intent.getStringExtra(SearchManager.QUERY);
        doSearch(query);
    }
}

完成这些更改后,您将在搜索视图中看到麦克风按钮。

如果您没有打电话,请检查您的密码:

 searchView.setIconifiedByDefault(true)

删除它后,您应该会看到“声音”图标。

答案 2 :(得分:-1)

只需将WHERE PageID = 1放入您的Manifest活动代码

即可
android:launchMode="singleTop"
