Button is not disabling even it is in valid condition

Button is not disabling even it is in valid condition - java

In my chat app, I'm adding Phone verification from user. So I want that when user will enter the number, after that sendVerification button should be setEnabled(true) and I set setEnabled(false) as default, but when I run the app, it is still showing as enabled without entering the digits.

#Override

getSupportActionBar().setTitle("Welcome to Phone Verification");
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
number = PhoneNumber.getText().toString();
if (number != null) {

} else {

}
sendVerification.setOnClickListener(new View.OnClickListener() {
#Override

#Override
public void onVerificationCompleted(PhoneAuthCredential phoneAuthCredential) {
}
#Override
public void onVerificationFailed(FirebaseException e) {

}

Use a TextWatcher() to know when the user enters the text in edit text. Do like this:-
Replace this:-
number = PhoneNumber.getText().toString();
if (number != null) {
sendVerification.setEnabled(true);
}
else {
sendVerification.setEnabled(false);
}
with this:-
PhoneNumber.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) {
String text = charSequence.toString();
if(!text.isEmpty()){
sendVerification.setEnabled(true);
}
}
#Override
public void afterTextChanged(Editable editable) {
}
});
sendVerification.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(!PhoneNumber.getText().toString().isEmpty()){
number = PhoneNumber.getText().toString();
PhoneNumber.setEnabled(false);
PhoneProgress.setVisibility(View.VISIBLE);
PhoneAuthProvider.getInstance().verifyPhoneNumber(
number,
60,
TimeUnit.SECONDS,
PhoneAuthActivity.this,
mCallbacks
);
}
else {
Toast.makeText(PhoneAuthActivity.this, "Empty Field", Toast.LENGTH_SHORT).show();
}
}
});

Replace
number = PhoneNumber.getText().toString();
if (number != null) {
sendVerification.setEnabled(true);
} else {
sendVerification.setEnabled(false);
}
with:
number = PhoneNumber.getText().toString();
if (number.isEmpty()) {
sendVerification.setEnabled(false);
} else {
sendVerification.setEnabled(true);
}

Set sendVerification.setEnabled(false) by default in onCreate(...) method and then apply TextChangedListener like this
PhoneNumber.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) {
if (charSequence.toString().equalsIgnoreCase("")) {
sendVerification.setEnabled(false);
} else {
sendVerification.setEnabled(true);
}
}
#Override
public void afterTextChanged(Editable editable) {
}
});
It will automatically disable sendVerification Button whenever PhoneNumber is blank

#Override

}
sendVerification.setOnClickListener(new View.OnClickListener() {

#Override
public void onVerificationFailed(FirebaseException e) {

};
}
}

number = PhoneNumber.getText().toString();
if (!number.isEmpty()) {
sendVerification.setEnabled(true);
}
This is all executed in onCreate before you get the chance to start typing. Once you start typing this code is not executed again. It is only executed once, when the activity is being created.
Solution: set up a TextWatcher on the phone number editText and enable/disable sendVerification in the TextWatcher#afterTextChanged method. See here for instructions on how to do it.

In your code
number = PhoneNumber.getText().toString();
if (!number.isEmpty()) {
sendVerification.setEnabled(true);
}
is executed only once at onCreate. You'll have to add a text change listener and enable/disable the button accordingly
like,
PhoneNumber.addTextChangedListener(new TextWatcher() {
#Override
public void afterTextChanged(Editable s) {}
#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)
{
sendVerification.setEnabled(true);
}
}
});

You need a TextWatcher to do what you wish to do, so add a TextWatcher to your EditText/TextView like below:
PhoneNumber.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) {
sendVerification.setEnabled(true);
}
}
#Override
public void afterTextChanged(Editable s) {
}
});
The reason your code wasn't working is because the onCreate() method does not get called after you start typing, meaning the condition for enabling your view is checked only once so any changes are not checked again.

How do I set a wallpaper based on the Image selected?

I'm making a wallpaper app similar in functionality to Google's new wallpaper app. There is a Horizontal Scroll View at the bottom with a list of Image Buttons that when clicked will show a preview of the wallpaper in the app. How do I tell the app to set the wallpaper from the one being previewed?

Thanks for any and all help in advance!

First , you need to set the required permission
<uses-permission android:name="android.permission.SET_WALLPAPER"/>
and then :
dsc18.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
WallpaperManager myWallpaperManager = WallpaperManager.getInstance(getApplicationContext());
try {
myWallpaperManager.setResource(onethreeone);
} catch (IOException e) {
e.printStackTrace();
}
dsc18.hasFocus();
}
});

how to update seekbar using a edittext

i read an example of how to show the progres of a seekbar to the edittext this is the web page:
Simple Seekbar In Android
now my problem is how to change the seekbar if i introduce a number inside the edittext box? thanks for any help
if you can acces the web page i will also post the code:
main:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<TextView
android:id="#+id/textView1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/hello" />
<EditText
android:id="#+id/editText1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_marginTop="94dp" >
<requestFocus />
</EditText>
<SeekBar
android:id="#+id/seekBar1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_below="#+id/textView1"
android:layout_marginTop="38dp" />
</RelativeLayout>
and the java code:
import android.app.Activity;
import android.os.Bundle;
import android.widget.EditText;
import android.widget.SeekBar;
import android.widget.SeekBar.OnSeekBarChangeListener;
public class SeekbarActivity extends Activity
{
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
SeekBar sb=(SeekBar) findViewById(R.id.seekBar1);
final EditText et=(EditText) findViewById(R.id.editText1);
sb.setOnSeekBarChangeListener(new OnSeekBarChangeListener()
{
#Override
public void onStopTrackingTouch(SeekBar seekBar)
{
}
#Override
public void onStartTrackingTouch(SeekBar seekBar)
{
}
#Override
public void onProgressChanged(SeekBar seekBar, int progress,
boolean fromUser)
{
//---change the font size of the EditText---
et.setText(String.valueOf(progress));
}
});
}
}

Use addTextChangedListener
A quick example :
//et and sk are class variables
et=(EditText)findViewById(R.id.editText);
sk = (SeekBar)findViewById(R.id.seekBar);
et.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) {
}
#Override
public void afterTextChanged(Editable s) {
try{
//Update Seekbar value after entering a number
sk.setProgress(Integer.parseInt(s.toString()));
} catch(Exception ex) {}
}
});
