这是发生错误的位置

enter c while (st.hasMoreElements()) {
        //Toast.makeText(getApplicationContext(), st.nextElement().toString().substring(0,1), Toast.LENGTH_LONG).show();
        test = st.nextElement().toString().substring(3,1);

            total+= Float.parseFloat(test);
        count++;
    }
下面是java类文件的全部活动

 pizza mApp;
EditText et_summary;
TextView tv_total;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_total);

    mApp=((pizza) getApplicationContext());
    et_summary = (EditText) findViewById(R.id.et_summary);
    tv_total = (TextView) findViewById(R.id.tv_total);
    //Toast.makeText(getApplicationContext(), "You have chosen the" + " " +  mApp.getGlobalVarValue(), Toast.LENGTH_LONG).show();
    et_summary.setText(mApp.getGlobalVarValue());
    String str = mApp.getGlobalVarValue();
    StringTokenizer st = new StringTokenizer(str,"$");
    String test="";
    float total=0;
    int count=0;
    while (st.hasMoreElements()) {
        //Toast.makeText(getApplicationContext(), st.nextElement().toString().substring(0,1), Toast.LENGTH_LONG).show();
        test = st.nextElement().toString().substring(3,1);
        if(count>0)
            total+= Float.parseFloat(test);
        count++;
    }
    et_summary.setText(mApp.getGlobalVarValue());
    tv_total.setText("Total :" + total+"");
    mApp.setGlobalClear();


}
public boolean isFloat( String input )
{
    try
    {
        Float.parseFloat( input );
        return true;
    }
    catch( Exception e)
    {
        return false;
    }
}
}

使用
locations=loadLocationData（）时，很明显，食品表不存在位于
菜单中的oodactivity

您可以通过在调用
loadLocationData
方法之前创建表来避免此错误。e、 g:-


db=openOrCreateDatabase("Restaurants_DB", Context.MODE_PRIVATE, null);
db.execSQL("CREATE TABLE IF NOT EXISTS food(id int, name text, price int);");
locations = loadLocationData();
addListenerOnButton();
initializeUI();



如果上面的问题解决了，您说它解决了，那么您应该将问题标记为已回答。如果你有后续问题，那么你应该问另一个问题。注意：错误是由以下原因引起的：
：java.lang.StringIndexOutOfBoundsException:字符串索引超出范围：-2
您不使用SQLiteOpenHepler或Room persistence library有什么原因吗？建议使用SQLite的两种方法是什么？
