Android：如何跟踪在将数据传输到另一个片段时单击的多个按钮

你好，我是android编程新手， 我有这个xml文件及其相关的java片段类

 <?xml version="1.0" encoding="utf-8"?>

    android:text="@string/sob" />

<Button
    android:id="@+id/allSchoolsButton"
    android:layout_width="wrap_content"
    android:layout_height="35dp"
    android:layout_marginLeft="150dp"

问题，当我将数据传输到另一个片段时，如何跟踪单击的按钮

请帮忙

当我将数据传输到另一个片段时，如何跟踪单击的按钮

正如所理解的，您正在寻找片段间数据传输。让您的父活动通过接口处理此传输（或您想要的任何其他操作）：

public interface InterFragmentDataTransferer {
     public void btnListener(String dataStr1, String dataStr2);
     // You may define here as many other methods as you need.
}

然后，在父活动中实现此接口，用所需的操作覆盖方法并最终实例化片段：

public MyFragmentHolderActivity extends Activity implements InterFragmentDataTransferer {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.your_parent_activity_layout);
        // Do other instantiation jobs;
        // .
        // .
        mFragment = MyFragment.newInstance();

    }

    public void btnListener(String dataStr1, String dataStr2) {
        // You've the desired data here :D ... so do whatever you'd like.
    }
}

最后，您将在片段的onAttach方法内的调用者片段内获得接口实例，该实例可用于传递数据：

public class MyFragment extends Fragment implements OnClickListener {

     private InterFragmentDataTransferer mFragDataTransferer;

     public static Fragment newInstance() {
        return new MyFragment();
     }

     @Override
     public void onAttach(Activity activity) {
        super.onAttach(activity);
        mFragDataTransferer = (InterFragmentDataTransferer) activity;
     }

     public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
          Log.d(TAG, "inside OncreateView()");
          ViewGroup rv = (ViewGroup) inflater.inflate(
                              R.layout.your_layout, container, false);

          (rv.findViewById(R.id.sisButton))
                             .setOnClickListener(this);
          (rv.findViewById(R.id.soeButton))
                             .setOnClickListener(this);
          (rv.findViewById(R.id.solButton))
                             .setOnClickListener(this);
          (rv.findViewById(R.id.sobButton))
                             .setOnClickListener(this);
          (rv.findViewById(R.id.allSchoolsButton))
                             .setOnClickListener(this);
          (rv.findViewById(R.id.smallButton))
                             .setOnClickListener(this);

          // TODO write your other code
    }


    @Override
    public void onClick(View v) {

          switch (v.getId()) {
             case R.id.sisButton:
                 // TODO write button click-action here
                 mFragDataTransferer.btnListener(dataStr1, dataStr2);
                 break;
             case R.id.soeButton:
                 // TODO write button click-action here
                 mFragDataTransferer.btnListener(dataStr1, dataStr2);
                 break;
             case R.id.solButton:
                 // TODO write button click-action here
                 mFragDataTransferer.btnListener(dataStr1, dataStr2);
                 break;
             case R.id.sobButton:
                 // TODO write button click-action here
                 mFragDataTransferer.btnListener(dataStr1, dataStr2);
                 break;
             case R.id.allSchoolsButton:
                 // TODO write button click-action here
                 mFragDataTransferer.btnListener(dataStr1, dataStr2);
                 break;
             case R.id.smallButton:
                 // TODO write button click-action here
                 mFragDataTransferer.btnListener(dataStr1, dataStr2);
                 break;
             default:
                break;
          }
    }
}

额外提示：不要重写片段构造函数来传递任何数据/接口，这可能会引发FragmentInstanceException，尽管通过newInstance（）方法作为param传递接口更安全，但正如我所读到的，也不推荐这样做
