导航抽屉中的目标操作栏项目

Question

I am currently working on an app that i implemented a toolbar and a search functionality on the toolbar with a searchview to filter list views which is working fine. I also have a navigation drawer whereby i also want one of its items to do exactly what the search functionality is doing on the toolbar. How do implement an intent to lead me to SearchView on toolbar when search item is clicked from navigation drawer.

menu_main for toolbar

<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    tools:context=".MainActivity">

    <item
        android:id="@+id/viewMode"
        android:orderInCategory="100"
        app:showAsAction="never"
        android:icon="@drawable/ic_view_compact_black_24dp"
        android:title="@string/view" />
    <item
// my search functionality
        android:id="@+id/search"
        android:orderInCategory="100"
        app:actionViewClass= "android.support.v7.widget.SearchView"
        app:showAsAction="ifRoom"
        android:icon="@drawable/ic_search"
        android:title="@string/search" />

Answer 1

Try the following code below:

private Menu mOptionsMenu;

    ...

    @Override
    public boolean onCreateOptionsMenu(final Menu menu) {
        mOptionsMenu = menu;
        ...
    }

    ...

    public boolean onNavigationItemSelected(MenuItem item) {
    ...
    } else if(id == R.id.nav_search) {
        MenuItem searchMenuItem = mOptionsMenu.findItem(R.id.menu_search);
        searchMenuItem.expandActionView();
    }
    ...

Answer 2

Add <category android:name="android.intent.category.DEFAULT" /> to your search activity in manifest. Then do this:

else if(id == R.id.nav_search) {

       startActivity(new Intent(Intent.ACTION_SEARCH));

    }
