我有一個RecyclerView，有很多卡可容納4 EditText。當我在一張卡的一個EditText中輸入數值時，它會在隨機卡中填充相同的值。令人驚訝的是不跳EditTexts例如：Android RecyclerView -Multiple Edittext同時改變
如果卡1的edittext1我輸入值，將填寫相同的值到edittext1在CARD8，如果我在CARD8更改值，將值更改回在卡1。有人可以告訴我爲什麼會發生這種情況。
預先感謝您
這裏是我的代碼：
public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> {
private String[] mDataset;
public String[][] data = new String[30][4];
public static class ViewHolder extends RecyclerView.ViewHolder {
// each data item is just a string in this case
public LinearLayout mCardView;
public ViewHolder(LinearLayout v) {
super(v);
mCardView = v;
}
}
// Provide a suitable constructor (depends on the kind of dataset)
public MyAdapter(String[] myDataset) {
mDataset = myDataset;
}
// Create new views (invoked by the layout manager)
@Override
public MyAdapter.ViewHolder onCreateViewHolder(ViewGroup parent,
int viewType) {
LinearLayout v = (LinearLayout) LayoutInflater.from(parent.getContext())
.inflate(R.layout.cards, parent, false);
ViewHolder vh = new ViewHolder(v);
return vh;
}
// Replace the contents of a view (invoked by the layout manager)
@Override
public void onBindViewHolder(ViewHolder holder, final int position) {
// - get element from your dataset at this position
// - replace the contents of the view with that element
final EditText txt = (EditText) holder.mCardView.findViewById(R.id.ip1_text);
final EditText txt2 = (EditText) holder.mCardView.findViewById(R.id.ip2_text);
final EditText txt3 = (EditText) holder.mCardView.findViewById(R.id.ip3_text);
final EditText txt4 = (EditText) holder.mCardView.findViewById(R.id.ip4_text);
txt.addTextChangedListener(new TextWatcher() {
@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
}
@Override
public void afterTextChanged(Editable s) {
data[position][0] = s.toString();
Log.d("DATA" + position + "0", s.toString());
}
});
txt2.addTextChangedListener(new TextWatcher() {
@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
}
@Override
public void afterTextChanged(Editable s) {
data[position][1] = s.toString();
Log.d("DATA" + position + "1", s.toString());
}
});
txt3.addTextChangedListener(new TextWatcher() {
@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
}
@Override
public void afterTextChanged(Editable s) {
data[position][2] = s.toString();
Log.d("DATA" + position + "2", s.toString());
}
});
txt4.addTextChangedListener(new TextWatcher() {
@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
}
@Override
public void afterTextChanged(Editable s) {
data[position][3] = s.toString();
Log.d("DATA" + position + "3", s.toString());
}
});
TextView t = (TextView) holder.mCardView.findViewById(R.id.serNo);
t.setText(mDataset[position]);
}
// Return the size of your dataset (invoked by the layout manager)
@Override
public int getItemCount() {
return mDataset.length;
}
public String[][] getData() {
return data;
}

記得回收視圖回收現有的視圖（這意味着如果一個視圖被創建，它將重新使用現有的一次），所以更好的寫入條件來清除文本\ – Killer
