hii..i am new to android..i am developing an android application on platform 2.1..
There are two textbox: one for Name and other for entering job.I want the values should be taken from the 2 textboxes editText1 and editText2 and inserted in my database whenever a user clicks the button.Please help im stuck in this part.
my code is creating the table, but values are not being inserted into it.
here are my two classes:
DbHelper.java
package test.db.help;
import android.content.Context;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteDatabase.CursorFactory;
import android.database.sqlite.SQLiteOpenHelper;
public class DbHelper extends SQLiteOpenHelper {
public static final String db_name = "mydb.db";
public static final int db_version = 1;
public final String TABLE = "test";
public final String C_Name = "Name";
public final String C_job = "Job";
public DbHelper(Context context, String db_name, CursorFactory factory,
int version) {
super(context, db_name, null, db_version);
// TODO Auto-generated constructor stub
}
@Override
public void onCreate(SQLiteDatabase db) {
// TODO Auto-generated method stub
String sql = String.format(
"create table %s ( %s TEXT, %s TEXT )",
TABLE, C_Name, C_job);
db.execSQL(sql);
}
@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
// TODO Auto-generated method stub
}
}
TestActivity.java
package test.db.help;
import android.app.Activity;
import android.content.ContentValues;
import android.database.sqlite.SQLiteDatabase;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
public class TestActivity extends Activity implements OnClickListener {
EditText Name,Job;
Button b;
DbHelper obj;
SQLiteDatabase db;
public static final String db_name = "mydb.db";
public static final int db_version = 1;
ContentValues val;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(test.db.help.R.layout.dbtesting);
Name=(EditText) findViewById(R.id.editText1);
Job = (EditText) findViewById(R.id.editText2);
obj=new DbHelper(TestActivity.this,db_name , null, db_version);
db=obj.getWritableDatabase();
}
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
val=new ContentValues();
val.clear();
val.put(obj.C_Name,Name.getText().toString());
val.put(obj.C_job,Job.getText().toString());
db.insert(obj.TABLE, null, val);
}
}
