I have two EdiText and when I write a number in the first one I would need the second to be set to 162 - first one. If it is necessary to re-type a second number, the component should recalculate the first number.
If I write something in the second the first must behave exactly like the second.
Below there is my code but it does not work:
inputScoreWe = findViewById(R.id.inputScoreWe);
inputScoreYou = findViewById(R.id.inputScoreYou);
View.OnClickListener inputScoreListener = new View.OnClickListener() {
@Override
public void onClick(View view) {
try {
int inputScoreWeInteger = Integer.parseInt(inputScoreWe.getText().toString());
int inputScoreYouInteger = Integer.parseInt(inputScoreYou.getText().toString());
if (inputScoreWeInteger > 0) {
inputScoreYouInteger = 162 - inputScoreWeInteger;
} else if (inputScoreYouInteger > 0) {
inputScoreWeInteger = 162 - inputScoreYouInteger;
}
String s1 = inputScoreWeInteger + "";
String s2 = inputScoreYouInteger + "";
inputScoreWe.setText(s1);
inputScoreYou.setText(s2);
} catch (Exception e) {
Toast.makeText(getApplicationContext(), "Error", Toast.LENGTH_LONG).show();
}
}
};
inputScoreWe.setOnClickListener(inputScoreListener);
inputScoreYou.setOnClickListener(inputScoreListener);
Use text change listener to trigger for everytime you change value
inputScoreWe.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) {
if(s.length() > 0){
inputScoreYou.setText(162 - Integer.parseInt(inputScoreYou.getText().toString())+"");
}
}
@Override
public void afterTextChanged(Editable s) {
}
});
