Question

我想知道在将数据插入数据库时按下键盘的DONE按钮应该怎么做？

我在这里使用多个edittext，当它到达最后一个编辑按钮时，我必须将所有数据插入到数据库中..

private static final String CREATE_DB_TABLE_BUSINESSINFO=

"CREATE TABLE " + TABLE_BUSINESS + "(" +

COL_BID + " INTEGER PRIMARY KEY AUTOINCREMENT,"+
COL_COMPANY_NAME + " TEXT NOT NULL ,"+
COL_ADD1 + " TEXT NOT NULL ," +
COL_ADD2 + " TEXT NOT NULL ," +
COL_ADD3 + " TEXT ,"+
COL_CITY +" TEXT NOT NULL ,"+
COL_PROVINCE + " TEXT NOT NULL ,"+
COL_POSTCODE + " TEXT NOT NULL ," +
COL_TEL1 + " TEXT NOT NULL ,"+
COL_TEL2 + " TEXT ,"+
COL_WEBSITE + " TEXT NOT NULL ,"+
COL_EMAIL + " TEXT NOT NULL ,"+
COL_TWITTER + " TEXT NOT NULL ,"+
COL_FACEBOOK + " TEXT NOT NULL ,"+
COL_WELBO + " TEXT NOT NULL" + ")" ;                                                

    private  static final String CREATE_BUSINESS_RECORD = "INSERT INTO "
        + TABLE_BUSINESS + " (" + COL_COMPANY_NAME + ", " 
                                + COL_ADD1+","

                                + COL_POSTCODE+","
                                + COL_TEL1+","

                                + COL_WELBO
        + ") VALUES (0,0,0,0,0,0,0,0,0,0,0,0,0,0);";                         

           public void onCreate(SQLiteDatabase db) {

        db.execSQL(CREATE_DB_TABLE_BUSINESSINFO);
        db.execSQL(CREATE_BUSINESS_RECORD);
    }

          public void inserRecord(EditText edtxt_company, EditText edtxt_add1,
        EditText edtxt_add2, EditText edtxt_add3, EditText edtxt_city,
        EditText edtxt_province, EditText edtxt_postcode,
        EditText edtxt_tel1, EditText edtxt_tel2, EditText edtxt_website,
        EditText edtxt_email, EditText edtxt_twitter,

    /*SQLiteDatabase mdb1=mDbHelper.getWritableDatabase();*/

    ContentValues record = new ContentValues();

    record.put("companyname", edtxt_company.toString());
    record.put("address1", edtxt_add1.toString());
    record.put("address2", edtxt_add2.toString());

    record.put("facebook", edtxt_facebook.toString());
    record.put("welbo", edtxt_welbo.toString());

    mDb.insert(CREATE_DB_TABLE_BUSINESSINFO, null,record); }

          IN MAINACTIVITY....FOR ADDING THE DATA.....


        @Override
                public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
                     if (actionId == EditorInfo.IME_ACTION_DONE) {
                         Log.i("Insert Successfully","Insert");
                             addrow();
                          }
                    return false;
                }
                private void addrow() {
                    try
                    {
                        mDbHelper2.inserRecord(edtxt_company, edtxt_add1,edtxt_add2, edtxt_add3,edtxt_city, edtxt_province,edtxt_postcode,edtxt_tel1,edtxt_tel2,edtxt_website,edtxt_email, edtxt_twitter, edtxt_facebook, edtxt_welbo);
                    }
                    catch (Exception e) {

                        e.printStackTrace();
                    }

制作一个

class DatabaseHelper
    public class DatabaseHelper extends SQLiteOpenHelper{
    SQLiteDatabase dbms1;
    DatabaseHelper dbHelper;
    Cursor records;
    public DatabaseHelper(Context context){
        super(context,"UserDatabase", null,1);
        Log.i("Information", "Database Created");
        // TODO Auto-generated constructor stub
    }
    @Override
    public void onCreate(SQLiteDatabase db) {
        // TODO Auto-generated method stub
    }
    @Override
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
        // TODO Auto-generated method stub

    }
    public void createTable(){
        try{
            dbms1=getWritableDatabase();
            String sql1="create table if not exists user(_id INTEGER  PRIMARY KEY AUTOINCREMENT, name text not null,emailid text,gender text,username text,password text,birthdate text,phonenumber text,admin boolean,image BLOB);";
            Log.i("haiyang:createDB=", sql1);
            dbms1.execSQL(sql1);
        }
        catch(SQLiteException e){
            Log.i("SQLiteException",e.toString());
        }
    }

    public void closeDatabase() {
        // TODO Auto-generated method stub
        try{
            dbms1.close();
        }
        catch(SQLiteException e){
            Log.i("SQLiteException",e.toString());
        }
    }
    public boolean inserRecord(String name,String emailid,String gender,String username,String password,String birthdate,String phonenumber,boolean admin,Drawable drawableResource) {
        // TODO Auto-generated method stub
        Bitmap image = ((BitmapDrawable)drawableResource).getBitmap();
        ByteArrayOutputStream out = new ByteArrayOutputStream();
        image.compress(Bitmap.CompressFormat.PNG, 100, out);
        ContentValues record=new ContentValues();
        record.put("name",name);
        record.put("emailid",emailid);
        record.put("gender",gender);
        record.put("username",username);
        record.put("password",password);
        record.put("birthdate",birthdate);
        record.put("phonenumber",phonenumber);
        record.put("admin",admin);
        record.put("image",out.toByteArray());

        try{
            dbms1=this.getWritableDatabase();
            dbms1.insert("user", null,record);
        }
        catch(SQLiteException e){
            Log.i("SQLiteException",e.toString());
        }
            return true;
    }
}

之后必须创建

的对象

DatabaseHelper dbHelper=new DatabaseHelper(this);
dbHelper.createTable();

现在调用insert

的DatabaseHelper class方法

dbHelper.insertRecord(....arguments....);

你写过 Toast
