Neste artigo vamos tratar a pesquisa e adicionar um menu para acessar uma outra tela.<\/p>\n\n\n\n

O arquivo strings.xml est\u00e1 assim no momento.<\/p>\n\n\n\n

Crie uma activity com o nome ReviewList e na view da ReviewList digite o seguinte c\u00f3digo:<\/p>\n\n\n\n
<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n<LinearLayout xmlns:android=\"http:\/\/schemas.android.com\/apk\/res\/android\"\n    android:layout_width=\"fill_parent\"\n    android:layout_height=\"fill_parent\"\n    android:orientation=\"vertical\">\n\n    <ListView\n        android:id=\"@android:id\/list\"\n        android:layout_width=\"fill_parent\"\n        android:layout_height=\"fill_parent\"\n        android:layout_weight=\"1\"\n        android:drawSelectorOnTop=\"false\" \/>\n\n    <TextView\n        android:id=\"@+id\/empty\"\n        android:layout_width=\"fill_parent\"\n        android:layout_height=\"fill_parent\"\n        android:text=\"\" \/>\n<\/LinearLayout><\/code><\/pre>\n\n\n\n
Agora no arquivo MainActivity.java vamos adicionar mais c\u00f3digo.<\/p>\n\n\n\n
Primeiro ao pesquisar academia vamos mostrar uma mensagem se o campo de academia ou local estiver vazio.<\/p>\n\n\n\n
A MainActivity.java ficou assim:<\/p>\n\n\n\n

\"\"<\/figure><\/div>\n\n\n\n
Vamos agora adicionar um menu e quando clicar no item do menu abrir a tela  ReviewList.<\/p>\n\n\n\n
Declare essa vari\u00e1vel: private static final int MENU_GET_REVIEWS <\/em><\/strong>= Menu.FIRST<\/em><\/strong>;<\/p>\n\n\n\n
Adicione este c\u00f3digo no MainActivity.java.<\/p>\n\n\n\n
    @Override\n    public boolean onCreateOptionsMenu(Menu menu) {\n        super.onCreateOptionsMenu(menu);\n        menu.add(0, this.MENU_GET_REVIEWS, 0, R.string.menu_get_reviews).setIcon(\n                android.R.drawable.ic_menu_more);\n        return true;\n    }\n\n\n    public boolean onOptionsItemSelected(MenuItem item) {\n        switch (item.getItemId()) {\n            case MENU_GET_REVIEWS:\n                Intent intent = new Intent(this, ReviewList.class);\n                startActivity(intent);\n                return true;\n        }\n        return false;\n    }<\/code><\/pre>\n\n\n\n
Agora quando voc\u00ea clicar no menu na op\u00e7\u00e3o Reviews, voc\u00ea ir\u00e1 para a tela do ReviewList.<\/p>\n\n\n\n
