How to Custamize Toast in Android?

You can customize your tost:
LayoutInflater mInflater=LayoutInflater.from(this);

View view=mInflater.inflate(R.layout.your_layout_file,null);
Toast toast=new Toast(this);
toast.setView(view);
toast.setDuration(Toast.LENGTH_LONG);
toast.show();

Or General way:
Toast.makeText(context,"Your message.", Toast.LENGTH_LONG).show();

How do you get the selected value of a spinner — Android

public class YourItemSelectedListener implements OnItemSelectedListener {

    public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) {
        String selected = parent.getItemAtPosition(pos).toString();
    }

    public void onNothingSelected(AdapterView parent) {
        // Do nothing.
    }
}

Finally, your ItemSelectedListener needs to be registered in the Spinner:

spinner.setOnItemSelectedListener(new MyOnItemSelectedListener());

SQLiteOpenHelper Demo

1.Activity:

package com.venkool.databasedemo;

import android.app.Activity;

public class DatabaseDemoActivity extends Activity {

      /** Called when the activity is first created. */

      MyDatabase database;

      @Override

      public void onCreate(Bundle savedInstanceState) {

            super.onCreate(savedInstanceState);

            setContentView(R.layout.main);

            database = new MyDatabase(this, "MyDB.sqlite", null, 1);

            database.insert("venkool", "2000");

      }

}

2.Database Class:

public class MyDatabase extends SQLiteOpenHelper {

      SQLiteDatabase sqliteDatabase;

      public MyDatabase(Context context, String name, CursorFactory factory,

                  int version) {

            super(context, name, factory, version);

            // TODO Auto-generated constructor stub

      }

      @Override

      public void onCreate(SQLiteDatabase db) {

            // TODO Auto-generated method stub

            db.execSQL("create table MyTable(name text,salary text)");

      }

      @Override

      public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {

            // TODO Auto-generated method stub

      }

      public void open() {

            sqliteDatabase = getWritableDatabase();

      }

      public void close() {

            sqliteDatabase.close();

      }

      public void insert(String name, String salary) {

            open();

           

            try {

                  ContentValues values = new ContentValues();

                  values.put("name", name);

                  values.put("salary", salary);

                  sqliteDatabase.insert("MyTable", null, values);

            } catch (Exception e) {

                  // TODO Auto-generated catch block

                  e.printStackTrace();

            }

            close();

      }

}
