Getting values from RecyclerView EditText?
I think you are looking for a callback, which means whenever a number on one of the EditTexts is changed you want the total number change too. So first of all you need to add an interface,
OnEditTextChanged Interface
public interface OnEditTextChanged {
void onTextChanged(int position, String charSeq);
}
Then you need too include this in the constructor of the adapter.
In the Adapter.java
private List<DataHolder> mDataSet;
private OnEditTextChanged onEditTextChanged;
public Adapter(List<DataHolder> myData, OnEditTextChanged onEditTextChanged) {
mDataSet = myData;
this.onEditTextChanged = onEditTextChanged;
}
In the onBindViewHolder of your Adapter you need to set a listener for text change and tell the fragment using onEditTextChanged object.
@Override
public void onBindViewHolder(ViewHolder holder, final int position) {
holder.anameTxtView.setText(mDataSet.get(position).getDname());
holder.abalanceTxtView.setText(mDataSet.get(position).getDbalance());
holder.adepositEditText.addTextChangedListener(new TextWatcher() {
@Override
public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {}
@Override
public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {
onEditTextChanged.onTextChanged(position, charSequence.toString());
}
@Override
public void afterTextChanged(Editable editable) {}
});
}
Add this array to your GroupCollectionFragment so you can save the values in your fragment and use them whenever you want them.
Integer[] enteredNumber = new Integer[1000];
change your constructor call in GroupCollectionFragment
mAdapter = new Adapter(holderList, new OnEditTextChanged() {
@Override
public void onTextChanged(int position, String charSeq) {
enteredNumber[position] = Integer.valueOf(charSeq);
updateTotalValue();
}
});
private void updateTotalValue() {
int sum = 0;
for (int i = 0; i < 1000; i++) {
sum += enteredNumber[i];
}
totalValue.setText(String.valueOf(sum));
}
Let me know if you want the whole files. I wrote it and built the apk, it works just fine.
You can get value at action done of keyboard. all you need is to set
android:imeOptions="actionDone"
in edit text. and then just use below code
adepositEditText.setOnEditorActionListener(new TextView.OnEditorActionListener() {
@Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
if (actionId == EditorInfo.IME_ACTION_DONE) {
// Do whatever you want here
return true;
}
return false;
});
Use TextChangedListener
on EditText
and save input in new HashMap
with key as a id of order/unique key for row.
adeposit.addTextChangedListener(new TextWatcher() {
public void afterTextChanged(Editable s) {}
public void beforeTextChanged(CharSequence s, int start,
int count, int after) {
}
public void onTextChanged(CharSequence s, int start,
int before, int count) {
// Save value her in HashMap
}
});
At the end get Values from HashMap
.
