android RecyclerView 里面嵌套editText，点击RecyclerView内部其他控件不会收起键盘

这个问题可以通过对RecyclerView和EditText的事件监听来解决。

首先，需要在RecyclerView的Adapter中为EditText设置焦点变化监听器，当EditText失去焦点时，隐藏软键盘。示例代码如下：

public class MyAdapter extends RecyclerView.Adapter<MyViewHolder> {

    private Context mContext;
    private List<String> mData;

    public MyAdapter(Context context, List<String> data) {
        mContext = context;
        mData = data;
    }

    @NonNull
    @Override
    public MyViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(mContext).inflate(R.layout.item_layout, parent, false);
        return new MyViewHolder(view);
    }

    @Override
    public void onBindViewHolder(@NonNull MyViewHolder holder, int position) {
        holder.editText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
            @Override
            public void onFocusChange(View v, boolean hasFocus) {
                if (!hasFocus) {
                    hideKeyboard(v);
                }
            }
        });
    }

    @Override
    public int getItemCount() {
        return mData.size();
    }

    private void hideKeyboard(View view) {
        InputMethodManager imm = (InputMethodManager) mContext.getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
    }
}

接下来，在RecyclerView的Item布局中，为除EditText外的其他控件设置点击事件监听器，当点击其他控件时，隐藏软键盘。示例代码如下：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <EditText
        android:id="@+id/edit_text"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"/>

    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Hide Keyboard"
        android:onClick="hideKeyboard"/>
</LinearLayout>

在Activity中，定义hideKeyboard方法，用于隐藏软键盘。示例代码如下：

public class MainActivity extends AppCompatActivity {

    private RecyclerView mRecyclerView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mRecyclerView = findViewById(R.id.recycler_view);
        mRecyclerView.setLayoutManager(new LinearLayoutManager(this));
        List<String> data = new ArrayList<>();
        for (int i = 0; i < 20; i++) {
            data.add("Item " + i);
        }
        MyAdapter adapter = new MyAdapter(this, data);
        mRecyclerView.setAdapter(adapter);
    }

    public void hideKeyboard(View view) {
        InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
    }
}

这样，当点击RecyclerView内部的其他控件时，软键盘就会被隐藏。
