如何在EditText的TextWatcher中获取getId（）(How to getId() within TextWatcher from EditText)

如何在EditText的TextWatcher中获取getId（）(How to getId() within TextWatcher from EditText)

我有一个动态EditText的ArrayList 。 我想在所有EditText上实现TextWatcher 。 我刚用于Loop并且很容易实现TextWatcher ，但是我无法在那里使用getTag() 。 请建议如何在动态添加的EditText上获取Tag

for (int z = 0; z < allwtEditTextList.size(); z++) { allwtEditTextList.get(z).addTextChangedListener(new TextWatcher() { @Override public void onTextChanged(CharSequence s, int start, int before, int count) { // TODO Auto-generated method stub } @Override public void beforeTextChanged(CharSequence s, int start, int count, int after) { // TODO Auto-generated method stub } @Override public void afterTextChanged(Editable s) { // TODO Auto-generated method stub Need getTag() here } }); }

I have a ArrayList of dynamic EditText. I want to implement TextWatcher on all EditText. I just used for Loop and easily implemented the TextWatcher, however I am unable to use getTag() there. Please suggest how can I get Tag on dynamically added EditText

for (int z = 0; z < allwtEditTextList.size(); z++) { allwtEditTextList.get(z).addTextChangedListener(new TextWatcher() { @Override public void onTextChanged(CharSequence s, int start, int before, int count) { // TODO Auto-generated method stub } @Override public void beforeTextChanged(CharSequence s, int start, int count, int after) { // TODO Auto-generated method stub } @Override public void afterTextChanged(Editable s) { // TODO Auto-generated method stub Need getTag() here } }); }

最满意答案

试试这个...

final ArrayList<EditText> allwtEditTextList = new ArrayList<EditText>(); ......... for (int z = 0; z < allwtEditTextList.size(); z++) { final int pos = z; allwtEditTextList.get(z).addTextChangedListener(new TextWatcher() { @Override public void onTextChanged(CharSequence s, int start, int before, int count) { // TODO Auto-generated method stub } @Override public void beforeTextChanged(CharSequence s, int start, int count, int after) { // TODO Auto-generated method stub } @Override public void afterTextChanged(Editable s) { // TODO Auto-generated method stub // Need getTag() here allwtEditTextList.get(pos).getTag(); } }); }

try this...

final ArrayList<EditText> allwtEditTextList = new ArrayList<EditText>(); ......... for (int z = 0; z < allwtEditTextList.size(); z++) { final int pos = z; allwtEditTextList.get(z).addTextChangedListener(new TextWatcher() { @Override public void onTextChanged(CharSequence s, int start, int before, int count) { // TODO Auto-generated method stub } @Override public void beforeTextChanged(CharSequence s, int start, int count, int after) { // TODO Auto-generated method stub } @Override public void afterTextChanged(Editable s) { // TODO Auto-generated method stub // Need getTag() here allwtEditTextList.get(pos).getTag(); } }); }
