Question

我已经阅读了有关此问题的所有旧问题，但我找不到适用于我的解决方案。我快疯了。以下是我尝试过的所有代码，没有人可以使用。

1

submit.setOnClickListener(new View.OnClickListener() { //Listner OnClik sul bottone "Cerca"             

            @Override
            public void onClick (View v) { //OnClick                    
                    Bundle bundle = new Bundle(); //Creo il bundle
                    Log.d("4","ok");
                    bundle.putString("dati", camporicerca.getText().toString()); //Metto nel parametro "dati" il testo nel campo di ricerca
                    Log.d("5","ok");
                    Intent in = new Intent(getActivity(), Risultato.class); //Istanzio l'activity
                    Log.d("6","ok");   
                    in.putExtras(bundle); //Passo il payload all'activity
                    Log.d("7","ok");   
                    startActivity(in); //Avvio l'activity   
                    Log.d("8","ok");
                }

            });

为什么不起作用？任何解决方案？

Answer 1

是否真的有必要从Fragment开始活动？我没有尝试过你在问题中分享过的代码。但你可以按照以下方式实现这个目标

创建片段

public class ClickFragment extends Fragment{
       << Fragment related code>>
}

创建一个接口，该接口具有以Bundle对象作为参数调用另一个活动的方法，例如。 callSecondActivity（Bundle bundle）
```
public interface FragmentCoordinator{

     void callSecondActivity(Bundle bundle);

}
```

在您的Activity类

中实现此接口

public class YourActivity extends Activity implements FragmentCoordinator {

  <<< Activity related code>>>

@Override
public void callSecondActivity(Bundle bundle){
    Intent in = new Intent(YourActivity.this, Risultato.class);
    in.putExtras(bundle);
    startActivity(in);
}

在当前片段中添加以下代码

     public class ClickFragment extends Fragment{
           << Fragment related code>>

         submit.setOnClickListener(new View.OnClickListener() { //Listner OnClik sul bottone "Cerca"              

            @Override
            public void onClick (View v) { //OnClick                    
                    Bundle bundle = new Bundle(); //Creo il bundle

                    bundle.putString("dati", camporicerca.getText().toString()); //Metto nel parametro "dati" il testo nel campo di ricerca
                    Activity activity = getActivity();
            FragmentCoordinator coordinator = (FragmentCoordinator)activity;
            coordinator.callSecondActivity(bundle);
                }

            });
    }

片段上的StartActivity
