this is my code in which the app is running just fine but the dialog box is not opening the button is clickable but no action is being performed
@Override public void onClick(View view){ AlertDialog.Builder mBuilder = new AlertDialog.Builder(appointmentpage.this); View mView = getLayoutInflater().inflate(R.layout.dialog_otp,null); final EditText mOTP = (EditText) mView.findViewById(R.id.enterOTP); final Button mVerify = (Button) mView.findViewById(R.id.verify); mVerify.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { if(mOTP.getText().toString().isEmpty()) { mVerify.setOnClickListener(new View.OnClickListener(){ @Override public void onClick(View view) { AlertDialog.Builder mBuilder1 = new AlertDialog.Builder(appointmentpage.this); View mView1 = getLayoutInflater().inflate(R.layout.confirmation_final,null); } }); } else{ Toast.makeText(appointmentpage.this, "Enter OTP", Toast.LENGTH_SHORT).show(); } }
