验证EditText输入并更新用户分数

Question

案例：
我问用户一个问题，答案是7。

如何验证EditText的条目是否为7，之后我想奖励1分。

//Question #1  
//If Answer is equal to 7 than award One Point   
int = score;

private EditText questionOneAnswer;

EditText text = (EditText) findViewById(R.id.Part2Question1);

String EditText = text.getText().toString().trim();

if(EditText.isEmpty() || EditText.length() == 0 || 
  EditText.equals("7") || EditText == null)
   {
    //EditText is empty
}

Answer 1

首先，您不能将预定义的类名用作变量名。其次是你对授予点的逻辑是不正确的。试试这个，

EditText text = (EditText) findViewById(R.id.Part2Question1);
String answer = text.getText().trim();

if(answer.equals("7"))
   {
    score++;
   }
else{
     // show some toast showing that answer is incorrect
   }
