Question

I´m trying to use a SearchView for my Application. First i added appcompat to my project:

 compile "com.android.support:appcompat-v7:19.0.1+"

secound i add this code to my menu:

<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@+id/action_search"
    android:title="@string/search"
    android:icon="@drawable/ic_action_search"
    android:showAsAction="ifRoom|collapseActionView"
    android:actionViewClass="android.support.v7.widget.SearchView" />
</menu>

but when i start the activity i get this:

03-07 17:25:39.110 16861-16861/de.treevo.app W/MenuInflater﹕ Cannot instantiate class: android.support.v7.widget.SearchView java.lang.reflect.InvocationTargetException at

and when i push the search icon nothing happen :(

Edit1:

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.offline, menu);
    MenuItem searchItem = menu.findItem(R.id.action_search);
    mSearchView = (SearchView) searchItem.getActionView();
    //setupSearchView(searchItem);

   // menu.findItem(R.id.action_search).getActionView();

    return true;
}
Was it helpful?

Solution 2

Try to add a custom prefixe on your layout like: 

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:app="http://schemas.android.com/apk/res-auto" >

      <item android:id="@+id/action_search"
          android:title="@string/search"
          android:icon="@drawable/ic_action_search"
          app:showAsAction="ifRoom|collapseActionView"
          app:actionViewClass="android.support.v7.widget.SearchView" />

</menu>

See the documentation, in the example, you must to add a custom prefixe (as "app" in the code above).

Also, instead of: 

MenuItem searchItem = menu.findItem(R.id.action_search);
mSearchView = (SearchView) searchItem.getActionView();

Try this: 

MenuItem searchItem = menu.findItem(R.id.action_search);
// with MenuItemCompat instead of your MenuItem
mSearchView = (SearchView) MenuItemCompat.getActionView(searchItem);

Let me know if this helps.

OTHER TIPS

In my case it works on development mode however crashes on release mode (export signed apk). To fix that please adding this line to proguard-rules.txt

-keep class android.support.v7.widget.SearchView { *; }
