Question

我制作的应用程序中有18个按钮（bAnswer1到bAnswer18）和6个文本视图（tvAnswer1到6）。我的意思是用3个单词中的2个单词切换6个单词（比如按钮，按 - 开）我用6个单词做了，每个单词把它们放在一个切片中（slice1到18）所以这段代码将重复自己的情况R. id.bAnswer18：你们会注意到它会休！我知道我可以通过添加一个for循环来使它变得非常简单但是它无法工作而我无法退出？！

有人可以帮我解决这个问题吗？

我的代码：

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;

你正在寻找的真正答案并非真正处于for循环中。

如果你这样做，for循环将有所帮助

 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);

请记住，不要在Activity上实现OnClickListener，让视图本身处理它，除非你真的需要自己处理/发送onClicks。
