素材検索ビューをデフォルトで開いたままにする方法

Question

検索ビューにhttps://github.com/MiguelCatalan/MaterialSearchViewを使用しています。 私は私の現在のコードは次のコード

にそれを更新した後Nayan Srivastava氏の答えによると

public class search extends AppCompatActivity { 
MaterialSearchView searchView; 
    Toolbar toolbar; 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_search); 
     searchView = (MaterialSearchView)findViewById(R.id.search_view); 
     toolbar = (Toolbar)findViewById(R.id.toolbar); 
     setSupportActionBar(toolbar); 
     getSupportActionBar().setTitle("Search"); 
     searchView.showSearch(); 
    } 



    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     getMenuInflater().inflate(R.menu.search, menu); 

     MenuItem item = menu.findItem(R.id.action_search); 
     searchView.setMenuItem(item); 

     return true; 
    } 
} 

ある

..私はmaterialsearchactivityに行くと、検索ビューを開いておきたいです

@Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_search); 
     searchView = (MaterialSearchView)findViewById(R.id.search_view); 
     searchView.performClick(); 
     toolbar = (Toolbar)findViewById(R.id.toolbar); 
     setSupportActionBar(toolbar); 
     getSupportActionBar().setTitle("Search"); 
     searchView.showSearch(); 
    } 

次のエラーが発生しています。

Answer 1

onCreateOptionsMenuでは、仕事をする必要がありますperformClick

@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    getMenuInflater().inflate(R.menu.search, menu); 

    MenuItem item = menu.findItem(R.id.action_search); 
    searchView.setMenuItem(item); 
    searchView.performClick(); 
    return true; 
} 

これを呼び出すことができます。

searchView.showSearch(false);

Answer 2

エラーがoverlapping.Toだけ使用したアニメーションを無効にするため、アニメーションにあると思われます

searchView.setOnSearchViewListener(new MaterialSearchView.SearchViewListener() { 
     @Override 
     public void onSearchViewShown() { 

     } 

     @Override 
     public void onSearchViewClosed() { 
      //To close the current activity 
       search.this.finish(); 
     } 
    });
