我是android新手。我正在创建一个应用程序,其中有一个注册表单,从那里输入值需要存储在MySQL表中。
这是java的源代码:
package com.example.entrepreneurexpress;
import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.util.ArrayList;
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.NameValuePair;
import org.apache.http.client.HttpClient;
import org.apache.http.client.entity.UrlEncodedFormEntity;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.message.BasicNameValuePair;
import org.json.JSONException;
import org.json.JSONObject;
import android.annotation.TargetApi;
import android.app.ActionBar;
import android.app.Activity;
import android.os.Build;
import android.os.Bundle;
import android.os.StrictMode;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
public class InvestorRegister extends Activity {
EditText YourName;
EditText email;
EditText password;
EditText confirmPassword;
Button btnClear, btnRegister;
String nm, emailAdd, cnfPass, pwd, result = null;
int code;
InputStream is = null;
@TargetApi(Build.VERSION_CODES.HONEYCOMB)
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.investors_registration);
if(Build.VERSION.SDK_INT >= 9) {
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
}
ActionBar aBar = getActionBar();
aBar.setDisplayHomeAsUpEnabled(true);
YourName = (EditText) findViewById(R.id.invRegName);
email = (EditText) findViewById(R.id.invRegEmail);
password = (EditText) findViewById(R.id.invRegPassword);
confirmPassword = (EditText) findViewById(R.id.invRegConfPassword);
btnRegister = (Button) findViewById(R.id.btnInvRegRegister);
btnRegister.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
if(
(YourName.getText().toString().trim().equals("")) ||
(email.getText().toString().trim().equals("")) ||
(password.getText().toString().trim().equals(""))
) {
Toast.makeText(getApplicationContext(), "Please Fill In All The Details", Toast.LENGTH_LONG).show();
} else {
nm = YourName.getText().toString().trim();
emailAdd = email.getText().toString().trim();
pwd = password.getText().toString().trim();
ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair(nm, email.getText().toString().trim()));
nameValuePairs.add(new BasicNameValuePair(emailAdd, email.getText().toString().trim()));
nameValuePairs.add(new BasicNameValuePair(pwd, password.getText().toString().trim()));
try{
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://www.bijukathemovie.com/insert.php");
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
is = entity.getContent();
Log.e("log_tag", "connection success ");
Toast.makeText(getApplicationContext(), "pass", Toast.LENGTH_SHORT).show();
} catch(Exception e) {
Log.e("log_tag", "Error in http connection "+e.toString());
Toast.makeText(getApplicationContext(), "Connection fail", Toast.LENGTH_SHORT).show();
}
try{
BufferedReader reader = new BufferedReader(new InputStreamReader(is,"iso-8859-1"),8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
is.close();
result=sb.toString();
} catch(Exception e) {
Log.e("log_tag", "Error converting result "+e.toString());
}
try {
JSONObject json_data = new JSONObject(result);
CharSequence w = (CharSequence) json_data.get("re");
Toast.makeText(getApplicationContext(), w, Toast.LENGTH_SHORT).show();
} catch (JSONException e) {
Log.e("log_tag", "Error parsing data "+e.toString());
Toast.makeText(getApplicationContext(), "JsonArray fail", Toast.LENGTH_SHORT).show();
}
}
}
});
}
}
这里是php的源代码:
<?php
require_once("storescripts/dbconnect.php");
$name=$_POST['nm'];
$emailAdd=$_POST['emailAdd'];
$pwd=$_POST['pwd'];
//echo "Your Name is: ". $name .". Your Email is: ". $emailAdd .". Your Password is: ". $pwd;
$q="INSERT INTO Investors VALUES('".$name."', '".$emailAdd."', '".$pwd."')";
$s= mysqli_query($con, $q);
if(!$s) {
$r["re"]="Inserting problem in database";
print(json_encode($r));
} else {
$r["re"]="Record inserted successfully";
print(json_encode($r));
}
mysqli_close($con);
?>
您可以看到图片here
数据库中的空白值除了id字段auto_increment。
请帮助我解决这个问题。感谢。
答案 0 :(得分:0)
你在参数中犯了一些错误
ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair(nm, email.getText().toString().trim()));
nameValuePairs.add(new BasicNameValuePair(emailAdd, email.getText().toString().trim()));
nameValuePairs.add(new BasicNameValuePair(pwd, password.getText().toString().trim()));
应该是:
nm = YourName.getText().trim();
emailAdd = email.getText().trim();
pwd = password.getText().trim();
ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("nm", nm));
nameValuePairs.add(new BasicNameValuePair("emailAdd", email));
nameValuePairs.add(new BasicNameValuePair("pwd", pwd));
BasicNameValuePair(String name,String value)
使用名称和值的默认构造函数。
