请帮助我...... :(

此DataHelper

＆＃13;

public class DataHelper extends SQLiteOpenHelper {

    private static final String DATABASE_NAME = "newpdil3.db";
    private static final int DATABASE_VERSION = 1;
    public DataHelper(Context context) {
        super(context, DATABASE_NAME, null, DATABASE_VERSION);
        // TODO Auto-generated constructor stub
    }

    @Override
    public void onCreate(SQLiteDatabase db) {
        // TODO Auto-generated method stub
        String sql = "create table pdil(id INTEGER PRIMARY KEY   AUTOINCREMENT,tiang text null,lat text null,long text null,area null,rayon null,jenis text null);";
        Log.d("Data", "onCreate: " + sql);
        db.execSQL(sql);

    }

    @Override
    public void onUpgrade(SQLiteDatabase arg0, int arg1, int arg2) {
        // TODO Auto-generated method stub

    }

您可以优化上述代码，首先将单选按钮

分组

    ton1.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View arg0) {
            // TODO Auto-generated method stub
            SQLiteDatabase db = dbHelper.getWritableDatabase();
            cursor = db.rawQuery("SELECT * FROM pdil WHERE tiang = '" +
                    tiang.getText().toString() + "'", null);
            if (cursor.getCount() > 0) {
                Toast.makeText(getApplicationContext(), "Data Sudah Ada", Toast.LENGTH_LONG).show();
            } else {

             RadioGroup rg1= (RadioGroup) findViewById(R.id.radio_grp);
            if(rg1.getCheckedRadioButtonId()!=-1){
                int id= rg1.getCheckedRadioButtonId();
                View radioButton = rg1.findViewById(id);
                int radioId = radioGroup.indexOfChild(radioButton);
                RadioButton btn = (RadioButton) rg1.getChildAt(radioId);
                String selection = (String) btn.getText();

                db.execSQL("insert into pdil(tiang,long,lat,jenis) values('" +
                        tiang.getText().toString() + "','" +
                        gps.getLongitude() + "','" +
                        gps.getLatitude() + "','"+ selection +"')");
                Toast.makeText(getApplicationContext(), "Berhasil", Toast.LENGTH_LONG).show();
                MainActivity.ma.RefreshList();
                finish();
            }

            }
        };
    });

更新您的DataHelper课程，如下所示：

public class DataHelper extends SQLiteOpenHelper {

    private static final String DATABASE_NAME = "newpdil3.db";
    private static final int DATABASE_VERSION = 1;
    public DataHelper(Context context) {
        super(context, DATABASE_NAME, null, DATABASE_VERSION);
        // TODO Auto-generated constructor stub
    }

    @Override
    public void onCreate(SQLiteDatabase db) {
        // TODO Auto-generated method stub
        String sql = "create table pdil(id INTEGER PRIMARY KEY AUTOINCREMENT, tiang text null, lat text null, long text null, area text null, rayon text null, jenis text null);";
        Log.d("Data", "onCreate: " + sql);
        db.execSQL(sql);
    }

    @Override
    public void onUpgrade(SQLiteDatabase arg0, int arg1, int arg2) {
        // TODO Auto-generated method stub

    }

    public void insertData(String tiang, String lat, String long, String jenis) {
        SQLiteDatabase db = this.getWritableDatabase();

        ContentValues values = new ContentValues();

        values.put("tiang", tiang);
        values.put("lat", lat);
        values.put("long", long);
        values.put("jenis", jenis);

        // Insert data 
        db.insert("pdil", null, values);
    }

    .................
    ........................
}

更新onClick()方法，如下所示：

DataHelper dbHelper  = new DataHelper(this);

ton1.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View arg0) {

            SQLiteDatabase db = dbHelper.getWritableDatabase();
            cursor = db.rawQuery("SELECT * FROM pdil WHERE tiang = '" +
                    tiang.getText().toString() + "'", null);

            if (cursor.getCount() > 0) {
                Toast.makeText(getApplicationContext(), "Data Sudah Ada", Toast.LENGTH_LONG).show();
            } else if (rd1.isChecked()) {
                dbHelper.insertData(tiang.getText().toString(), String.valueOf(gps.getLatitude()), String.valueOf(gps.getLongitude()), rd1.getText().toString()); 

                Toast.makeText(getApplicationContext(), "Berhasil", Toast.LENGTH_LONG).show();
                MainActivity.ma.RefreshList();
                finish();
            }else if (rd2.isChecked()) {
                dbHelper.insertData(tiang.getText().toString(), String.valueOf(gps.getLatitude()), String.valueOf(gps.getLongitude()), rd2.getText().toString()); 

                Toast.makeText(getApplicationContext(), "Berhasil", Toast.LENGTH_LONG).show();
                MainActivity.ma.RefreshList();
                finish();
            }else if (rd3.isChecked()) {
                dbHelper.insertData(tiang.getText().toString(), String.valueOf(gps.getLatitude()), String.valueOf(gps.getLongitude()), rd3.getText().toString());      

                Toast.makeText(getApplicationContext(), "Berhasil", Toast.LENGTH_LONG).show();
                MainActivity.ma.RefreshList();
                finish();
            }
        };
