Java 在android中取消选中1个复选框时，如何取消选中全选复选框

我想在我的项目中的功能，其中点击全选复选框列表中的所有复选框必须被选中，取消选中复选框的所有其他复选框必须被取消选中。我通过以下操作实现了此功能：

/*in my main activity i have done this*/

  cbSelectAll.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {

            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                for (int i = 0; i < resumeSearchList.size(); i++) {
                    resumeSearchList.get(i).setSelected(cbSelectAll.isChecked());
                }
                cvSearchResultListAdapter.notifyDataSetChanged();
            }
        });
    }

现在我的问题是，每当我取消选中列表中的任何复选框时，必须取消选中“全选”按钮。请帮忙

提前感谢

您可以在适配器的

holder.cbSelect.

上设置

OnCheckedChangeListener

holder.cbSelect.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {

            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                    dataList.get(holder.getAdapterPosition()).setSelected(isChecked);
                    // here you can call listener to get notified 
            }
        });
    }

您可以让

侦听器在
活动中获得通知。

对于添加侦听器

1。创建一个
界面
：

public interface OnMyCheckBoxCheckedChangeListener {
    void onMyCheckBoxCheckedChange();
}

private OnMyCheckBoxCheckedChangeListener mOnMyCheckBoxCheckedChangeListener;

    public YourAdapter(..., ..., OnMyCheckBoxCheckedChangeListener onMyCheckBoxCheckedChangeListener) {
            mOnMyCheckBoxCheckedChangeListener = onMyCheckBoxCheckedChangeListener;
        }

holder.cbSelect.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {

            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                    dataList.get(holder.getAdapterPosition()).setSelected(isChecked);
                    mOnMyCheckBoxCheckedChangeListener.onMyCheckBoxCheckedChange(); 
            }
        });
    }

yourRecyclerView.setAdapter(new YourAdapter(..., ..., new OnMyCheckBoxCheckedChangeListener() {
    @Override
    public void onMyCheckBoxCheckedChange() {
        // you will get notified here.
    }
}));

2。在适配器的构造函数中添加参数：

public interface OnMyCheckBoxCheckedChangeListener {
    void onMyCheckBoxCheckedChange();
}

private OnMyCheckBoxCheckedChangeListener mOnMyCheckBoxCheckedChangeListener;

    public YourAdapter(..., ..., OnMyCheckBoxCheckedChangeListener onMyCheckBoxCheckedChangeListener) {
            mOnMyCheckBoxCheckedChangeListener = onMyCheckBoxCheckedChangeListener;
        }

holder.cbSelect.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {

            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                    dataList.get(holder.getAdapterPosition()).setSelected(isChecked);
                    mOnMyCheckBoxCheckedChangeListener.onMyCheckBoxCheckedChange(); 
            }
        });
    }

yourRecyclerView.setAdapter(new YourAdapter(..., ..., new OnMyCheckBoxCheckedChangeListener() {
    @Override
    public void onMyCheckBoxCheckedChange() {
        // you will get notified here.
    }
}));

3。要通知的调用接口：

public interface OnMyCheckBoxCheckedChangeListener {
    void onMyCheckBoxCheckedChange();
}

private OnMyCheckBoxCheckedChangeListener mOnMyCheckBoxCheckedChangeListener;

    public YourAdapter(..., ..., OnMyCheckBoxCheckedChangeListener onMyCheckBoxCheckedChangeListener) {
            mOnMyCheckBoxCheckedChangeListener = onMyCheckBoxCheckedChangeListener;
        }

holder.cbSelect.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {

            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                    dataList.get(holder.getAdapterPosition()).setSelected(isChecked);
                    mOnMyCheckBoxCheckedChangeListener.onMyCheckBoxCheckedChange(); 
            }
        });
    }

yourRecyclerView.setAdapter(new YourAdapter(..., ..., new OnMyCheckBoxCheckedChangeListener() {
    @Override
    public void onMyCheckBoxCheckedChange() {
        // you will get notified here.
    }
}));

4。从活动中设置适配器：

public interface OnMyCheckBoxCheckedChangeListener {
    void onMyCheckBoxCheckedChange();
}

private OnMyCheckBoxCheckedChangeListener mOnMyCheckBoxCheckedChangeListener;

    public YourAdapter(..., ..., OnMyCheckBoxCheckedChangeListener onMyCheckBoxCheckedChangeListener) {
            mOnMyCheckBoxCheckedChangeListener = onMyCheckBoxCheckedChangeListener;
        }

holder.cbSelect.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {

            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                    dataList.get(holder.getAdapterPosition()).setSelected(isChecked);
                    mOnMyCheckBoxCheckedChangeListener.onMyCheckBoxCheckedChange(); 
            }
        });
    }

yourRecyclerView.setAdapter(new YourAdapter(..., ..., new OnMyCheckBoxCheckedChangeListener() {
    @Override
    public void onMyCheckBoxCheckedChange() {
        // you will get notified here.
    }
}));

为列表的复选框添加一个check change监听器，当您的值为false时，取消选中select all复选框如何在此处设置监听器。您可以解释更多吗？
