Change button background color based on previous color

I have a very simple problem
consider I'm retrieving a string value online using getText() Method
Now depending upon value of string I have set my button background to red and blue.
If string value is red then button background is red and if it is blue then blue.
Now if I implement onClicklistener to same button I would like to changes it's Background color. If it was Red then change it to blue and if it was blue then change it to red as long as user presses key.
mSolved = (Button) itemView.findViewById(R.id.book_solved);
mSolved.setText(g.getColorvalue());
if("Blue".equals(holder.mSolved.getText())){
mSolved.setBackgroundColor(BLUE);
}
if("Red".equals(holder.mSolved.getText())){
.mSolved.setBackgroundColor(RED);
}
mSolved.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(Background color is already BLue)
{
change to Red
}
else
{
Change to Blue
}
}

Try using FLAG variables. Something similar to this.
mSolved = (Button) itemView.findViewById(R.id.book_solved);
mSolved.setText(g.getColorvalue());
boolean IS_BLUE = false;
boolean IS_RED = false;
if("Blue".equals(holder.mSolved.getText())){
mSolved.setBackgroundColor(BLUE);
IS_BLUE = true;
}
if("Red".equals(holder.mSolved.getText())){
mSolved.setBackgroundColor(RED);
IS_RED = true;
}
mSolved.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(IS_BLUE)
{
mSolved.setBackgroundColor(RED);
IS_RED = true;
IS_BLUE = false;
}
else if(IS_RED)
{
mSolved.setBackgroundColor(BLUE);
IS_BLUE = true;
IS_RED = false;
}
}

Try this code:
mSolved = (Button) findViewById(R.id.book_solved);
mSolved.setBackgroundColor(Color.parseColor("#009900"));
mSolved.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View tView) {
ColorDrawable buttonColor = (ColorDrawable) mSolved.getBackground();
int colorId = buttonColor.getColor();
// Log.i("INFO", "find color value for new color " + colorId);
if (colorId == -3407872) { // color is read
mSolved.setBackgroundColor(Color.parseColor("#009900"));
}
else {
mSolved.setBackgroundColor(Color.parseColor("#cc0000"));
}
}
});

hide button if text length is < 1 in android studio

I'm new to Android and Java and I'm busy editing an existing app. I am trying to hide a button if no text is getting pulled in from a webservice. I have made it work with another button when the text is being populated
if (textEvent.length() > 1) {
buttonEventSetup.setVisibility(View.INVISIBLE);
}
but when I used:
if (textEvent.length() < 1) {
buttonAccessControl.setVisibility(View.INVISIBLE);
}
nothing seems to happen.
I don't know if the code snippet is in the wrong place or something else is overwriting the code. Here is my activity code:
package com.example.dsouchon.myapplication;
public class MainActivity extends AppCompatActivity {
#Override

if(Local.isSet(getApplicationContext(), "LoggedIn"))
{
String loggedInUser = Local.Get(getApplicationContext(), "LoggedIn");
if(loggedInUser.length()>0)
{
buttonEventSetup.setVisibility(View.VISIBLE);
}
else
{
buttonEventSetup.setVisibility(View.GONE);
}
}
else
{
buttonEventSetup.setVisibility(View.GONE);
}
if(Local.isSet(getApplicationContext(), "EventName"))

textEvent.setText( event);
Button buttonAccessControl = (Button)findViewById(R.id.buttonAccessControl);
buttonAccessControl.setEnabled(true);
//HIDES SET EVENT BUTTON WHEN EVENT IS SET
if (textEvent.length() > 1) {
buttonEventSetup.setVisibility(View.INVISIBLE);
}
if (textEvent.length() < 1) {

You are getting the length of Textview that will not work.Use the text length.This should work
String event = Local.Get(getApplicationContext(), "EventName");
//HIDES SET EVENT BUTTON WHEN EVENT IS SET
if (event.length() > 1) {
buttonEventSetup.setVisibility(View.VISIBLE);
}
if (event.length() < 1) {
buttonAccessControl.setVisibility(View.INVISIBLE);
}

In your code above textEvent is not a string value. It is an Object of type TextView. length() in this case will not return the length of the text contained within that element. You will need to explicitly get the text string before you can get the length of it. This is acquired using the getText() method on the TextView.
Your code should look like the following:
//HIDES SET EVENT BUTTON WHEN EVENT IS SET
if (textEvent.getText().length() >= 1) {
buttonEventSetup.setVisibility(View.VISIBLE);
}
if (textEvent.getText().length() < 1) {
buttonAccessControl.setVisibility(View.INVISIBLE);
}
You also have INVISIBLE on both cases in your posted code example.
Note that your code also does not handle cases where the text length == 1. You could simplify the whole block with the following.
Note: any value != 0 is classed as true
buttonEventSetup.setVisibility(textEvent.getText().length() ? View.VISIBLE : View.INVISIBLE);

How to validate to rating bar on Button click in Android?

I want to validation on RatingBar in Android. I have 5 rating Bar and 1 Button. I don't want to submit the data without pressed the rating bar. I want to take validation on Rating bar.

public void addListenerOnRatingBar_two() { ... }
public void addListenerOnRatingBar_three() { ... }

public void addListenerOnRatingBar_five() { ... }

At first set all rating bar to 0 value. Then on click to button, check if the value has altered in all of them. If so, only valid else invalid.
Also you can use listener to each rating bar and change value of some boolean variable to true
Example:
boolean flag1 = false;
boolean flag2 = false;
.... //similarly upto 5
Then in rating bar listener1
{
flag1 = true;
}
Similarly for all set flag to be true
And in button onClickListener do the following:
if(flag1 && flag2 && flag3 && flag4 && flag5){
//do your work
}else{
//display message that one of the rating bar hasn't been touched
}

How to add a wait function till a button is pressed?

I want to add a wait till, Button (Enter) is pressed function to my code But i am still new to this.
I know there are some errors in my code I was playing around with it, But what I want to do is when I press the line Button I want it to display Input X,Y,Z then wait till enter is pressed to execute the rest of my code I want to add in. How would I implement something like this in my code?
Here is my MainActivity Class:
public class MainActivity extends Activity implements OnClickListener {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button enter = (Button) findViewById(R.id.enter);
Button line = (Button) findViewById(R.id.line);
Button arc = (Button) findViewById(R.id.arc);
line.setOnClickListener(this);
enter.setOnClickListener(this);
arc.setOnClickListener(this);
}
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
TextView vector = (TextView) findViewById(R.id.point);
TextView index = (TextView) findViewById(R.id.index);
TextView info = (TextView) findViewById(R.id.info);
EditText cl = (EditText) findViewById(R.id.editText1);
DrawingUtils call = new DrawingUtils();
switch (v.getId()) {
case R.id.line:
info.setText("Input X,Y,Z");
// This Is Where the Wait Function Will GO
vector.setText(call.addVertice());
index.setText("1");
break;
case R.id.enter:
String In = cl.getText().toString();
call.setInputCoords(In);
break;
case R.id.arc:
info.setText("Enter Vertice1 ");
// Code for entering Vertice1(Also has wait function)
info.setText("Enter Vertice2");
// Code for entering Vertice2(Also has wait function)
info.setText("Enter Height");
//Code for entering Height(Also has wait function)
}
}
}
Here is my DrawingUtils Class:
public class DrawingUtils {
String inputCoords;
String[] vertice;
public String getInputCoords() {
return inputCoords;
}
public void setInputCoords(String inputCoords) {
this.inputCoords = inputCoords;
}
public String addVertice() {
int i = 0;
vertice = inputCoords.split(",");
return vertice[i];
}
}

I think this is what you are after. Apologies if not!
Use a boolean flag to handle state within your app. This way you can execute different code if something has happened.
boolean enterPressed = false;
#Override
public void onClick(View v) {
TextView vector = (TextView) findViewById(R.id.point);
TextView index = (TextView) findViewById(R.id.index);
TextView info = (TextView) findViewById(R.id.info);
EditText cl = (EditText) findViewById(R.id.editText1);
DrawingUtils call = new DrawingUtils();
switch (v.getId()) {
case R.id.line:
if (enterPressed) {
vector.setText(call.addVertice());
index.setText("1");
}
else {
info.setText("Input X,Y,Z");
}
break;
case R.id.enter:
String In = cl.getText().toString();
call.setInputCoords(In);
enterPressed = true;
break;
case R.id.arc:
info.setText("Enter Vertice1 ");
