The upper part of my layout is not displayed when I launch the application on the phone, and in the studio everything is well displayed. I'm talking about the one where the name of the application. Here is the class code;
public class FileManager extends Activity { ListView listDirs; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_file_manager); String [] paths = {"/storage/emulated/0/", "/storage/extSdCard/"}; listDirs = (ListView) findViewById(R.id.list); ArrayAdapter<String> adapter = new ArrayAdapter<>(this, R.layout.file_list, paths); listDirs.setAdapter(adapter); } }
