檢查按下按鈕的順序 - Android

Question

我的應用程序中有四個按鈕。每個按鈕都有一個整數作爲文本。我將如何檢查按鈕是否按照整數值升序排列？我想這樣做，如果一個按鈕被按下按鈕，會有一種告訴用戶他們選擇了錯誤順序的某種類型的通知。

什麼是這樣的：

// put your button text integers in ascending order in an array 
int[] integersInAscendingOrder = {buttonText1, buttonText2, buttonText3, buttonText4}; 

int i = 0; 

// for each button's on click listener do something like the following: 
button.setOnClickListener(new OnClickListener() { 
    @Override 
    public void onClick(View v) { 
     int value = Integer.parseInt(button.getText().toString()); 
     checkOrder(value); 
    } 
}); 

// have a function check order pressed 
private void checkOrder(int value) { 
    // see if the button pressed is the right one 
    if (value == integersInAscendingOrder[i]) { 
     if (i == 3) { 
      // insert code to run once all buttons pressed in right order 
     } else { 
      // insert code (if any) where less than all buttons pushed but in right order 
      // increase i 
      i++; 
     } 
    } else { 
     // button out of order 
     Toast.makeText(this, "Wrong order", Toast.LENGTH_LONG).show() 
    } 
}
