Yes I have been thru several questions on this topic. It's about the setText on a textWatcher field. I am quite new to all this and maybe that's why Haven't been able to apply a good fix. I am not much of a explaining type so... Here is my code:
package com.newera.speedsnfeeds;
import java.math.BigDecimal;
import java.math.RoundingMode;
import android.annotation.SuppressLint;
import android.app.Activity;
import android.os.Bundle;
import android.text.Editable;
import android.text.TextWatcher;
import android.widget.EditText;
public class Main1Activity extends Activity implements TextWatcher {
private EditText dia, sfm, rpm,flutes,load,feed;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main1);
dia = (EditText) findViewById(R.id.dia);
dia.addTextChangedListener(this);
sfm = (EditText) findViewById(R.id.sfm);
sfm.addTextChangedListener(this);
rpm = (EditText) findViewById(R.id.rpm);
rpm.addTextChangedListener(this);
flutes = (EditText) findViewById(R.id.flutes);
flutes.addTextChangedListener(this);
load = (EditText) findViewById(R.id.load);
load.addTextChangedListener(this);
feed = (EditText) findViewById(R.id.feed);
feed.addTextChangedListener(this);
rpm.setText("1");
feed.setText("");
}
@Override
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
// TODO Auto-generated method stub
}
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
// TODO Auto-generated method stub
}
@Override
public void afterTextChanged(Editable s) {
// TODO Auto-generated method stub
calculate();
}
@SuppressLint("UseValueOf")
private void calculate() {
if (dia.getText().toString().compareTo("") == 0
|| sfm.getText().toString().compareTo("") == 0
|| rpm.getText().toString().compareTo("") == 0
||flutes.getText().toString().compareTo("") == 0
||load.getText().toString().compareTo("") == 0)
{
//rpm.setText("1");
//feed.setText("1");
}else{
if (dia.getText().toString().compareTo(".") == 0
|| dia.getText().toString().compareTo("-") == 0
|| dia.getText().toString().compareTo("-0") == 0
|| dia.getText().toString().compareTo("-00") == 0
|| dia.getText().toString().compareTo("-000") == 0
|| dia.getText().toString().compareTo("-0000") == 0
|| dia.getText().toString().compareTo("-.") == 0
|| sfm.getText().toString().compareTo(".") == 0
|| sfm.getText().toString().compareTo("-") == 0
|| sfm.getText().toString().compareTo("-0") == 0
|| sfm.getText().toString().compareTo("-00") == 0
|| sfm.getText().toString().compareTo("-000") == 0
|| sfm.getText().toString().compareTo("-0000") == 0
|| sfm.getText().toString().compareTo("-.") == 0
|| rpm.getText().toString().compareTo("-") == 0
|| rpm.getText().toString().compareTo("-0") == 0
|| rpm.getText().toString().compareTo("-00") == 0
|| rpm.getText().toString().compareTo("-000") == 0
|| rpm.getText().toString().compareTo("-0000") == 0
|| flutes.getText().toString().compareTo("-") == 0
|| flutes.getText().toString().compareTo("-0") == 0
|| flutes.getText().toString().compareTo("-00") == 0
|| flutes.getText().toString().compareTo("-000") == 0
|| flutes.getText().toString().compareTo("-0000") == 0
|| load.getText().toString().compareTo("-") == 0
|| load.getText().toString().compareTo("-0") == 0
|| load.getText().toString().compareTo("-00") == 0
|| load.getText().toString().compareTo("-000") == 0
|| load.getText().toString().compareTo("-0000") == 0
|| feed.getText().toString().compareTo("-") == 0
|| feed.getText().toString().compareTo("-0") == 0
|| feed.getText().toString().compareTo("-00") == 0
|| feed.getText().toString().compareTo("-000") == 0
|| feed.getText().toString().compareTo("-0000") == 0)
{
//rpm.setText("1");
//feed.setText("1");
} else {
float diam = Float.valueOf(dia.getText().toString());
float sfmm = Float.valueOf(sfm.getText().toString());
float rpmm = Float.valueOf(rpm.getText().toString());
float flutesm = Float.valueOf(flutes.getText().toString());
float loadm = Float.valueOf(load.getText().toString());
BigDecimal trpm = new BigDecimal((sfmm *3.82 / diam));
trpm = trpm.setScale(0,RoundingMode.UP);
BigDecimal tfeed = new BigDecimal((rpmm * flutesm * loadm));
tfeed = tfeed.setScale(1,RoundingMode.UP);
rpm.setText("1"+ trpm);
feed.setText("1"+tfeed);
}
}
{
}
}
}
It's not done yet I need to have it be able to calculate sfm and load is why it needs to be edit text fields.
I have read other questions on this same problem but they were just different enough of a situation I wasn't able to apply the ideas. probably cause I am so new to programming in general.
Hopefully this is a good way to start a question.
P.S. sorry for the messy code hopefully having the code helps someone show me how to apply a fix to my current code. Also don't hesitate to let me know if this is too unclear or not, need the xml ect.
