如何使用SQLite将整个数据库表数据显示到android中的TextView中

所以这是我从数据库表中获取整个数据的代码：

public List<Person> getAllPerson()
{
    List<Person> personList = new ArrayList<Person>();

    //select query
    String selectQuery = "SELECT  * FROM " + DATABASE_TABLE;

    SQLiteDatabase db = this.getWritableDatabase();
    Cursor cursor = db.rawQuery(selectQuery,null);


    for (cursor.moveToFirst(); !cursor.isAfterLast(); cursor.moveToNext())
    {
         Person person = new Person();
            person.setId(Integer.parseInt(cursor.getString(0)));
            person.setName(cursor.getString(1));
            person.setHotness(cursor.getString(2));
            person.setAge(Integer.parseInt(cursor.getString(3)));

            // Adding person to list
            personList.add(person);
    }

    return personList;

}

这是我将表数据显示到TextView的代码：

public class SQLiteView extends Activity
  {

private TextView tv;
@Override
protected void onCreate(Bundle savedInstanceState)
{
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.sqlview);
    tv = (TextView) findViewById(R.id.tvDBdisplay);

    DbHelper d = new DbHelper(this);

    List<Person> person = d.getAllPerson();

    for (Person p: person)
    {
        String data =p.getId() + " " + p.getName() + " " + p.getHotness() +      " " + p.getAge();
        tv.setText(data);

    }

   }    
  }

解决方法

tv.append(p.toString());

因为TextView已在内部保留文本.

见TextView.append().
