我正在制作像密码管理员这样的应用。我的更新按钮正常工作，我的视图按钮正在工作，并提供所有数据库。我可以在操作栏的搜索小部件中键入我的查询，但是当我按下输入时没有任何反应....我需要帮助，我已经尝试了所有的东西....下面是代码
MainActivity.java //我想在搜索小部件中键入查询
public class MainActivity extends Activity implements OnClickListener {
Button sqlUpdate, sqlView, sqlDelete;
EditText sqlWebsite, sqlUser, sqlPass;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
sqlUpdate = (Button) findViewById(R.id.update_button);
sqlView = (Button) findViewById(R.id.view_button);
sqlWebsite = (EditText) findViewById(R.id.websiteText);
sqlUser = (EditText) findViewById(R.id.userText);
sqlPass = (EditText) findViewById(R.id.passText);
sqlUpdate.setOnClickListener((android.view.View.OnClickListener) this);
sqlView.setOnClickListener((android.view.View.OnClickListener) this);
