Question

我在滑动标签中使用了几个片段。我创建的最后一个在我的应用程序中正确显示，但点击按钮和编辑文本并没有做任何事情。我认为这是我在工作室中创建片段的方式。

我该如何调试这种情况？

我添加了java代码：

   public class StoreWords extends Fragment {

    public StoreWords() {
        // Required empty public constructor
    }

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // Inflate the layout for this fragment
    return inflater.inflate(R.layout.store_words_fragment, container, false);
}

@Override
public void onActivityCreated(Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);

    initFileSave();
    add_w_edit = (EditText) getActivity().findViewById(R.id.add_diffwords_edit);

    Button add = (Button) getActivity().findViewById(R.id.add_diffwords);
    add.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            addWords();
        }
    });

    Button del = (Button) getActivity().findViewById(R.id.remove_diffwords);
    del.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            addWords();
        }
    });
}

和布局文件：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context="com.example.bernard.speechparole.StoreWords"
    >

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textAppearance="?android:attr/textAppearanceLarge"
    android:text="Large Text"
    android:id="@+id/text_words"
    />

<Button
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/add_diffwords"
    android:layout_marginLeft="10dp"
    android:text="@string/add"
    android:layout_marginTop="15dp"
    android:layout_below="@id/text_words"
    />

<EditText
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textAppearance="?android:attr/textAppearanceMedium"
    android:id="@+id/add_diffwords_edit"
    android:layout_toRightOf="@id/add_diffwords"
    android:layout_marginLeft="30dp"
    android:layout_alignBottom="@id/add_diffwords"
    />

<Button
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/remove_diffwords"
    android:text="@string/delete"
    android:layout_below="@+id/add_diffwords"
    android:layout_marginTop="15dp"
    android:layout_marginLeft="10dp"
    />

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical"
    android:fillViewport="false">

    <ListView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:scrollbarAlwaysDrawVerticalTrack="true"
        android:id="@+id/list_words"
        android:layout_marginTop="10dp"
        android:layout_below="@id/remove_diffwords"
        />
</ScrollView>
</RelativeLayout>

Answer 1

执行onCreateView

内的操作

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {

   View view = inflater.inflate(R.layout.store_words_fragment,
    container, false);
   Button button = (Button) view.findViewById(R.id.add_diffwords):
   button.setOnClickListener(new OnClickListener()
   {
             @Override
             public void onClick(View v)
             {
                // your code here
             } 
   }); 
   return view;
}

Answer 2

  public class StoreWords extends Fragment {

    public StoreWords() {
        // Required empty public constructor
    }

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // Inflate the layout for this fragment
    View rootview=inflater.inflate(R.layout.store_words_fragment, container, false)
    add_w_edit = (EditText) rootview.findViewById(R.id.add_diffwords_edit);

    Button add = (Button) rootview.findViewById(R.id.add_diffwords);
    add.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            addWords();
        }
    });

    Button del = (Button) getActivity().findViewById(R.id.remove_diffwords);
    del.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            addWords();
        }
    });
    return rootview;
}

@Override
public void onActivityCreated(Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);

    initFileSave();


}

您要扩展片段布局的问题，但是当您将侦听器连接到视图时，您会在活动布局中搜索它们。

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,   Bundle savedInstanceState) {

   View view = inflater.inflate(R.layout.store_words_fragment, null, false);
   Button button = (Button) view.findViewById(R.id.add_diffwords):
   button.setOnClickListener(new OnClickListener(){
           @Override
           public void onClick(View v){
              addWords();
           } 
   }); 

  //Other code and views that you want handle events

  return view;
}

当你打电话给这个。getActivity（）findViewById（R.id.add_diffwords）;这意味着您尝试搜索并设置侦听器以在活动布局中查看。

片段加载布局但按钮和edittext不活动
