代码示例1
You have to use Appcompat library for that. Which is used like below:

dashboard.xml



    


Activity file (in Java):

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

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

    SearchManager searchManager = (SearchManager) MainActivity.this.getSystemService(Context.SEARCH_SERVICE);

    SearchView searchView = null;
    if (searchItem != null) {
        searchView = (SearchView) searchItem.getActionView();
    }
    if (searchView != null) {
        searchView.setSearchableInfo(searchManager.getSearchableInfo(MainActivity.this.getComponentName()));
    }
        return super.onCreateOptionsMenu(menu);
}

Activity file (in Kotlin):

override fun onCreateOptionsMenu(menu: Menu?): Boolean {
    menuInflater.inflate(R.menu.menu_search, menu)

    val searchItem: MenuItem? = menu?.findItem(R.id.action_search)
    val searchManager = getSystemService(Context.SEARCH_SERVICE) as SearchManager
    val searchView: SearchView? = searchItem?.actionView as SearchView

    searchView?.setSearchableInfo(searchManager.getSearchableInfo(componentName))
    return super.onCreateOptionsMenu(menu)
}

manifest file:

 

        
            
                
            
            
                
            

            
        

searchable xml file:




And at last, your SearchResultsActivity class code. for showing result of your search.
