在我的数据库中，我有表 AndroidGameMode，但是当我尝试将一些数据插入表中时，我收到此错误，表示我的列之一不存在

那是我的 databaseHandler 类
这是我的ResultClass
package com.example.jogodogalo.jogador1;
public class Results {
int _id;
String _name;
int _wins;
int _ties;
int _losses;
int _points;
public Results(){
}
public Results (int id, String name, int wins, int ties, int losses, int points){
this._id = id;
this._name = name;
this._wins = wins;
this._losses = losses;
this._ties = ties;
this._points=points;
}
public Results (String name, int wins, int ties, int losses, int points){
this._name = name;
this._wins = wins;
this._ties = ties;
this._losses = losses;
this._points = points;
}
public Results(int points){
this._points = points;
}
public int getID(){
return this._id;
}
public void setID(int id){
this._id = id;
}
public String getName(){
return this._name;
}
public void setName(String name){

}

}
public void setWins(int wins){

}

this._ties = ties;
}
public int getLosses(){
return this._losses;
}
public void setLosses(int losses){
this._losses = losses;
}
public int getPoints(){
return this._points;
}
//ta mal, quando se faz um set tu nao retornas nada
public void setPoints(int points){
this._points = points;
}
@Override
public String toString() {
return this.getName();
}
}
我的插入代码
public void onClick(DialogInterface dialog, int whichButton) {
String name = mPlayerName.getText().toString();
String win = mPlayerCount.getText().toString();
int wins_jogador1 = Integer.parseInt(win);
String ties = mTieCount.getText().toString();

String losses = mAndroidCount.getText().toString();
int losses_jogador1 = Integer.parseInt(losses);
String pontuacao = mPointsCount.getText().toString();
int pontuaçao_jogador1 = Integer.parseInt(pontuacao);
if(pontuaçao_jogador1 == 0){
Toast myToast = Toast.makeText(getApplicationContext(), "Não tem qualquer pontuação. \nNão é possível guardar.",
Toast.LENGTH_LONG);
myToast.setGravity(Gravity.CENTER_HORIZONTAL|Gravity.CENTER_VERTICAL, 0, 100);
myToast.setDuration(3000);
myToast.show();
}else if(pontuaçao_jogador1 != 0){
DataBaseHandler db = new DataBaseHandler(getApplicationContext());
Results theResultados = new Results(name, wins_jogador1, ties_jogador1, losses_jogador1, pontuaçao_jogador1);
db.addResults(theResultados);
//que estranho :S ele teima com o playerPoints nao sei porque diz que a cioluna nao existe
Intent intent = new Intent(JogoDoGalo.this, MainMenu.class);
JogoDoGalo.this.startActivity(intent);
