Android - 如何把這個循環

Question

我做了一個應用程序，其中我有18個按鈕（bAnswer1至bAnswer18）和6個文字瀏覽（tvAnswer1至6）。我的意思是用2個3字（如按鈕，bu - tt - on）分割6個單詞，我用6個單詞做了這些單詞，每個單詞放在一個切片中（切片1到18），所以這個代碼會重複自己的情況R. id.bAnswer18：你們會注意到它會是休息！我知道我可以通過添加一個for循環來使它非常簡單，但它不會工作，我不能離開？！

有人能幫我擺脫這個嗎？

我的代碼：

public void onClick(View arg0) { 
    // TODO Auto-generated method stub 

    switch (arg0.getId()) { 
    case R.id.bAnswer1: 

     if (testing1 != 6) { 
      String old = tvAnswer1.getText().toString(); 
      tvAnswer1.setText(old + slice1); 
      bAnswer1.setVisibility(View.GONE); 
      break; 

     } 
     if (testing2 != 6) { 
      String old = tvAnswer2.getText().toString(); 
      tvAnswer2.setText(old + slice1); 
      bAnswer1.setVisibility(View.GONE); 
      break; 
     } 
     if (testing3 != 6) { 
      String old = tvAnswer3.getText().toString(); 
      tvAnswer3.setText(old + slice1); 
      bAnswer1.setVisibility(View.GONE); 
      break; 
     } 
     if (testing4 != 6) { 
      String old = tvAnswer4.getText().toString(); 
      tvAnswer4.setText(old + slice1); 
      bAnswer1.setVisibility(View.GONE); 
      break; 
     } 
     if (testing5 != 6) { 
      String old = tvAnswer5.getText().toString(); 
      tvAnswer5.setText(old + slice1); 
      bAnswer1.setVisibility(View.GONE); 
      break; 
     } 
     if (testing6 != 6) { 
      String old = tvAnswer6.getText().toString(); 
      tvAnswer6.setText(old + slice1); 
      bAnswer1.setVisibility(View.GONE); 
      break; 
     } 

     break; 
    case R.id.bAnswer2: 
     if (testing1 != 6) { 
      String old = tvAnswer1.getText().toString(); 
      tvAnswer1.setText(old + slice2); 
      bAnswer2.setVisibility(View.GONE); 
      break; 

     } 
     if (testing2 != 6) { 
      String old = tvAnswer2.getText().toString(); 
      tvAnswer2.setText(old + slice2); 
      bAnswer2.setVisibility(View.GONE); 
      break; 
     } 
     if (testing3 != 6) { 
      String old = tvAnswer3.getText().toString(); 
      tvAnswer3.setText(old + slice2); 
      bAnswer2.setVisibility(View.GONE); 
      break; 
     } 
     if (testing4 != 6) { 
      String old = tvAnswer4.getText().toString(); 
      tvAnswer4.setText(old + slice2); 
      bAnswer2.setVisibility(View.GONE); 
      break; 
     } 
     if (testing5 != 6) { 
      String old = tvAnswer5.getText().toString(); 
      tvAnswer5.setText(old + slice2); 
      bAnswer2.setVisibility(View.GONE); 
      break; 
     } 
     if (testing6 != 6) { 
      String old = tvAnswer6.getText().toString(); 
      tvAnswer6.setText(old + slice2); 
      bAnswer2.setVisibility(View.GONE); 
      break; 
     } 
     break; 

Answer 1

您正在尋找真正的答案是不是真的在一個for循環。

for循環會幫助，如果你做到這一點

OnClickListener myOnClick = new OnClickListener() { 
//privately paste what you had 
public void onClick(View v) { 
if (testing1 != 6) { 
     String old = tvAnswer1.getText().toString(); 
     tvAnswer1.setText(old + slice1); 
     v.setVisibility(View.GONE); 
     break; 

    } 
    if (testing2 != 6) { 
     String old = tvAnswer2.getText().toString(); 
     tvAnswer2.setText(old + slice1); 
     v.setVisibility(View.GONE); 
     break; 
    } 
    if (testing3 != 6) { 
     String old = tvAnswer3.getText().toString(); 
     tvAnswer3.setText(old + slice1); 
     v.setVisibility(View.GONE); 
     break; 
    } 
    if (testing4 != 6) { 
     String old = tvAnswer4.getText().toString(); 
     tvAnswer4.setText(old + slice1); 
     v.setVisibility(View.GONE); 
     break; 
    } 
    if (testing5 != 6) { 
     String old = tvAnswer5.getText().toString(); 
     tvAnswer5.setText(old + slice1); 
     v.setVisibility(View.GONE); 
     break; 
    } 
    if (testing6 != 6) { 
     String old = tvAnswer6.getText().toString(); 
     tvAnswer6.setText(old + slice1); 
     v.setVisibility(View.GONE); 
     break; 
    }}); 


Button[] answerButtons = new Button[18]; 

for(Button answer : answerButtons) 
    answer.setOnClickListener(myOnClick); 

記住，不要與你的活動實現OnClickListener，讓自己的意見處理它，除非你真的需要處理/調度onClicks自己。
