DatabaseConnect is the name of the Android Application Project that has been created in Eclipse in Ubuntu Platform.
One of the java file Inside DatabaseConnect->src->co.package.datewithme is shown Below.
package com.example.datewithme;
import android.app.Activity;
import android.content.Intent;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;
import android.os.Bundle;
import android.text.InputType;
import android.view.View;
import android.widget.EditText;
import android.widget.ImageView;
import android.widget.Toast;
public class Login extends Activity{
Intent i=null;
ImageView im=null;
EditText tv1,tv4;
boolean flag=false;
SQLiteDatabase db=null;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.login);
im=(ImageView)findViewById(R.id.show_hide2);
tv1=(EditText)findViewById(R.id.phone2);
tv4=(EditText)findViewById(R.id.password2);
db=openOrCreateDatabase("mydb", MODE_PRIVATE, null);
// db.execSQL("create table if not exists login(name varchar,mobile_no varchar,email_id varchar,password varchar,flag varchar)");
im.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
if(flag==false)
{
im.setImageResource(R.drawable.hide);
tv4.setInputType(InputType.TYPE_TEXT_VARIATION_PASSWORD);
flag=true;
}
else
{
im.setImageResource(R.drawable.show);
tv4.setInputType(129);
flag=false;
}
}
});
}
public void action(View v)
{
switch(v.getId())
{
case R.id.signin2:
i=new Intent(this,Signin.class);
startActivityForResult(i, 500);
overridePendingTransition(R.anim.slide_in_top, R.anim.slide_out_bottom);
finish();
break;
case R.id.start:
String mobile_no=tv1.getText().toString();
String password=tv4.getText().toString();
if(mobile_no==null||mobile_no==""||mobile_no.length()<10)
{
show("Please Enter Correct mobile number.");
}
else if(password==null||password==""||password.length()<6)
{
show("Please Enter Correct Password.");
}
else
{
Cursor c=db.rawQuery("select * from login where mobile_no='"+mobile_no+"' and password='"+password+"'",null);
c.moveToFirst();
if(c.getCount()>0)
{
i=new Intent(this,Welcome.class);
startActivityForResult(i,500);
overridePendingTransition(R.anim.slide_in_right, R.anim.slide_out_left);
db.close();
finish();
}
else
show("Wrong Password or Mobile number.");
}
break;
}
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
overridePendingTransition(R.anim.slide_in_left, R.anim.slide_out_right);
}
public void show(String str)
{
Toast.makeText(this, str, Toast.LENGTH_LONG).show();
}
}
The error message generated is R cannot be resolved to a variable.But i have R.java file in my Project DatabaseConnect->gen->com.example.Databaseconnect->BuilConfig.java,R.java.
The ScreenShot is shown below.
I Searched all the possibilities for the solution by going through these links. 123
But din't got the proper solution.
I came to know the naming convention got some errors like DatabaseConnect and Datewithme. So i kept the same name to both and then clean and run the project but after that its that its taking previous name itself.
An help is appreciated
