这是我的代码
if(c!=null)
{
c.moveToFirst();
String col = c.getString(2); //
check.setText(col);
check.setVisibility(0);
while(!c.isAfterLast())
{
String col1 = c.getString(1);
String col2 = c.getString(2);
String col3 = c.getString(3);
while(!c.isAfterLast())
{
TextView que1 = new TextView(this);
que1.setText(col1);
lymn.addView(que1);
if(col3.equals("Date"))
{
DatePicker dp = new DatePicker(this);
lymn.addView(dp);
break;
}
if(col3.equals("User Input"))
{
EditText ed = new EditText(this);
ed.setWidth(250);
lymn.addView(ed);
break;
}
if(col3.equals("YES/NO"))
{
yes1.setText("Yes");
no1.setText("NO");
rg1.addView(yes1);
rg1.addView(no1);
lymn.addView(rg1);
break;
}
if(col3.equals("High Average Low"))
{
High1.setText("High");
Avg1.setText("Average");
Low1.setText("Low");
rg2.addView(High1);
rg2.addView(Avg1);
rg2.addView(Low1);
lymn.addView(rg2);
break;
}
if(col3.equals("Excellent Good Average Poor"))
{
exce1.setText("Excellent");
good1.setText("Good");
avg11.setText("Average");
poor1.setText("Poor");
rg3.addView(exce1);
rg3.addView(good1);
rg3.addView(avg11);
rg3.addView(poor1);
lymn.addView(rg3);
break;
}
break;
}
c.moveToNext();
}
}
当我运行这段代码时,我得到了以下错误
