Android-如何在MainActivity中从RecyclerView检索EditText值 [英] Android - How To retrieve EditText value from RecyclerView in MainActivity

问题描述

如何从MainActivity中RecyclerView创建的所有EditText中检索值?

How can I retrieve the value from all EditTexts created by the RecyclerView in MainActivity?

在我的RecyclerView适配器中，我扩展了内部类:

In my RecyclerView Adapter I'm extending my inner class:

public class MyPersonalAdapter extends RecyclerView.Adapter<MyPersonalAdapter.MyPersonalViewHolder>

我在该内部类中获得对EditText的引用:

I'm getting a reference to the EditText in that inner class:

 class MyPersonalViewHolder extends RecyclerView.ViewHolder {

        TextView numberTextView;
        EditText nameEditText;

        public MyPersonalViewHolder(View itemView) {
            super(itemView);
            numberTextView = (TextView) itemView.findViewById(R.id.tv_number);
            nameEditText = (EditText) itemView.findViewById(R.id.et_name);
        }
    }

在我的MainActivity中，我想使用:

and in my MainActivity I want to use:

for (int i = 0; i < count; i++) {
    String name = "Somehow get that name";
    cv.put(MyContract.MyEntry.COLUMN_NAME, "name");
}

推荐答案

使其正常运行，下面是编辑后的代码:

mAdapter = new MyClassAdapter(this, mDataset.size);
mRecyclerView.setAdapter(mAdapter);
mRecyclerview.setItemViewCacheSize(mDataset.size());

List<ContentValues> list = new ArrayList<>();

for (int i = 0; i < mDataset.size(); i++) {
    View view = recyclerView.getChildAt(i);
    EditText nameEditText = (EditText) view.findViewById(R.id.et_name);
    String name = nameEditText.getText().toString();

    ContentValues cv = new ContentValues();
    cv.put(MyContract.MyEntry.COLUMN_NAME, name);
    list.add(cv)
}

// I encapsulated this in a try catch
for (ContentValues c:list) {
    mDb.insert(MyClassContract.MyClassEntry.TABLE_NAME, null, c);
}
