ブール値は常にfalseを返します

Question

メールのメールアドレスが一致しているかどうか、パスワードの長さが0より大きいかどうかを確認しようとしていますので、ブール値を使用して確認しましたが、ここに私のJavaコードだ値をtrueに変更することができませんでした：ブールの両方がfalseを返す

private boolean mEmail_Correct = false; 
private boolean mPass_Correct = false; 

mEmail.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) { 
     if (android.util.Patterns.EMAIL_ADDRESS.matcher(s.toString()).matches()){mEmail_Correct = true;} 
     else {mEmail_Correct = false;}}}); 

mPassword.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) { 
     if (s.lenght>0){mPass_Correct = true;} 
     else {mPass_Correct = false;}}}); 

if (mEmail_Correct && mPass_Correct){}//I need to make sign in btn light 
else {}//I need to make sign in btn dim/faint 

//But nothing happen so what can i use instead of private booleans 

ので、私はmEmail_Correct =真のだと思いtrueにブールの値を変更するにはどのような方法があります。うまく動作しません。

あなたは、彼が正しく

private boolean mEmail_Correct = false; 
private boolean mPass_Correct = false; 
mEmail.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) { 
    if (android.util.Patterns.EMAIL_ADDRESS.matcher(s.toString()).matches()){emailWrittenCorrect(true);} 
    else {emailWrittenCorrect(false);}}}); 

mPassword.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) { 
     if (s.lenght>0){passwordWrittenCorrect(true);} 
     else {passwordWrittenCorrect(false);}}}); 

private passwordWrittenCorrect(boolean x){ 
    passwordEmailCheck(null,x); 
} 
private void emailWrittenCorrect(boolean x){ 
    passwordEmailCheck(x,null); 
} 
private passwordEmailCheck(boolean emailStat, boolean passwordStat){ 
    if(emailStat!=null){ 
     mEmail_Correct = emailStat; 

    } 
    if(passwordStat!=null){ 
     mPass_Correct = passwordStat 
    } 
    if(emailStat && passwordStat){ 
     //show button 
    } 

}
