我正在尝试将editText字段发送到下一个recycler list的{{1}}，但我无法获取它。问题是我无法看到列表中添加的activity字段列表。例如：当我从editText添加水银并点击保存editText时，我可以看到button中的水银。但是，当我写下金星并点击保存按钮时，水银消失并出现金星。
这是我的回收商recyclerView。
adapter这是public RecyclerViewAdapter(Context context, ArrayList<String> nameList){
layoutInflater = LayoutInflater.from(context);
itemsName = nameList;
}
@Override
public RecyclerViewAdapter.ItemHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View itemView = layoutInflater.inflate(R.layout.text_view,parent, false);
return new ItemHolder(itemView, this);
}
@Override
public void onBindViewHolder(RecyclerViewAdapter.ItemHolder holder, int position) {
holder.setItemName(itemsName.get(position));
}
@Override
public int getItemCount() {
return (null != itemsName ? itemsName.size() : 0);
}
public void setOnItemClickListener(OnItemClickListener listener){
onItemClickListener = listener;
}
public OnItemClickListener getOnItemClickListener(){
return onItemClickListener;
}
public interface OnItemClickListener{
public void onItemClick(ItemHolder item, int position);
}
public static class ItemHolder extends RecyclerView.ViewHolder implements View.OnClickListener{
private RecyclerViewAdapter parent;
TextView textItemName;
public ItemHolder(View itemView, RecyclerViewAdapter parent) {
super(itemView);
itemView.setOnClickListener(this);
this.parent = parent;
textItemName = (TextView) itemView.findViewById(R.id.herecomes);
}
public void setItemName(CharSequence name){
textItemName.setText(name);
}
public CharSequence getItemName(){
return textItemName.getText();
}
@Override
public void onClick(View v) {
final OnItemClickListener listener = parent.getOnItemClickListener();
if(listener != null){
listener.onItemClick(this, getPosition());
}
}
}}
activity字段，我点击保存editText后发送字段值。
button这是包含 public class MyEditor extends AppCompatActivity {
EditText textIn,txtHeading;
Button buttonAdd,btnsave;
ArrayList<String> nameList = new ArrayList<String>();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.editor);
txtHeading = (EditText)findViewById(R.id.heading);
buttonAdd = (Button)findViewById(R.id.add);
btnsave =(Button) findViewById(R.id.btn_save);
btnsave.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String newName = txtHeading.getText().toString().trim();
if(newName.length()!=0) {
nameList.add(newName);
txtHeading.setText("");
Intent intent = new Intent(getApplicationContext(), BuilderPage.class);
intent.putStringArrayListExtra("key", nameList);
nameList.add(newName);
int listsize = nameList.size();
for (int i = 0; i < listsize; i++) {
Log.i("Lists are", nameList.get(i));
Log.i("Lists are", "The size of array is:" + nameList.size());
}
startActivity(intent);
Toast.makeText(MyEditor
.this, "You added" + newName.toUpperCase() + "in your view", Toast.LENGTH_LONG).show();
}
}
});
}}
