<?php
include ('config.php');
$sql = "SELECT * FROM UserInfo WHERE email='".$email."'";
$r = mysqli_query($con,$sql);
$result = array();
while($row = mysqli_fetch_array($r)){
array_push($result,array(
'password'=>$row['password'],

echo json_encode(array('result'=>$result));
mysqli_close($con);
?>

public class ForgotPasswordActivity extends AppCompatActivity {
private String fremail;
private ProgressDialog pDialog;
protected EditText femail;
protected Button mSubmitButton;
TextView pas;
private static String url_create_book = "http://cloud.....com/broccoli/fpassword.php";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_forgot_password);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
pas=(TextView)findViewById(R.id.pas) ;
femail=(EditText)findViewById(R.id.feml);
Button submit= (Button) findViewById(R.id.sbtn);
submit.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
pDialog = new ProgressDialog(ForgotPasswordActivity.this);
pDialog.setMessage("Please wait..");
pDialog.setIndeterminate(false);
pDialog.setCancelable(true);
pDialog.show();
fremail = femail.getText().toString();
// new CreateNewProduct().execute();
StringRequest stringRequest = new StringRequest(Request.Method.POST, url_create_book,
new Response.Listener<String>() {
@Override
public void onResponse(String response) {
pDialog.dismiss();
try {
JSONObject object = new JSONObject(response);
JSONArray jsonArray = object.getJSONArray("result");
JSONObject jsonObject = jsonArray.getJSONObject(0);
// fetch password from JSON
String password = jsonObject.getString("password");
// use password in textviewfemail.setText(password, TextView.BufferType.EDITABLE);
pas.setText(password, TextView.BufferType.EDITABLE);
}
catch (JSONException e) {
Toast.makeText(ForgotPasswordActivity.this, e.toString(), Toast.LENGTH_LONG).show();
}
}
},
new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
pDialog.dismiss();
Toast.makeText(ForgotPasswordActivity.this, error.toString(), Toast.LENGTH_LONG).show();
}
}) {
@Override
protected Map<String, String> getParams() {
Map<String, String> params = new HashMap<String, String>();
params.put("email", fremail);
return params;
}
};
RequestQueue requestQueue = Volley.newRequestQueue(ForgotPasswordActivity.this);
requestQueue.add(stringRequest);
}
});
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
onBackPressed();
return true;
default:
return super.onOptionsItemSelected(item);
}
}
}
