我獲取JSON數據對於我的測驗應用程序,如何匹配答案並增加計數,如果它是正確的?
JSON數據如下:
{
"results":[
{
"id":4,
"ps":"Besides gases, air also contains",
"op1":"Smoke",
"op2":"Water vapour",
"op3":"Dust particles",
"op4":"All of these",
"resType":"multiple",
"ans1":null,
"ans2":null,
"ans3":null,
"ans4":"Yes",}......
.......
我存儲所有接收到的數據中的ArrayList如下:
questionList = new ArrayList<String>();
opList1 = new ArrayList<>();
opList2 = new ArrayList<>();
opList3 = new ArrayList<>();
opList4 = new ArrayList<>();
answer1 = new ArrayList<>();
.........................
.........................
上的每個按鈕點擊我有做了這樣的事情:
Button op1, op2, op3, op4;
int count;(GLobal)
public void onClick(View v) {
String message = op4.getText().toString();
TextView show = (TextView) findViewById(R.id.textViewChoice);
Toast.makeText(getBaseContext(), message, 1000).show();
show.setText(message);
if (op4.getText().equals("Yes")) {
count = count + 1;
} else if (op4.getText().equals("null"))
count = count;
}
每當我的計數= 0
檢查op4.getText()值? – sasikumar
在這裏你的邏輯是完全錯誤的!你必須得到「ans4」對象,然後與條件匹配! –
opList4.add(mcq.get(currentPosition).getOp4()); op.setText(mcq.get(currentPosition).getOp4()。toString()); –
