Question

我有5个可动态添加的editTexts片段：

 List<TextView> ArrayQuestionsEditTexts =new ArrayList<TextView>();

 for(int i=0; i<5; i++){
       View to_add = inflater.inflate(R.layout.list_item_add_new_offer,
                        options_layout,false);

                EditText question = (EditText) 
                to_add.findViewById(R.id.editTextQuestion);

                ArrayQuestionsEditTexts.add(question);

                options_layout.addView(to_add);
 }

我希望当用户单击键盘上的next按钮将焦点传递到ArrayQuestionsEditTexts列表中的下一个edittext时。

我尝试：

             for (int i = 0; i < ArrayQuestionsEditTexts.size()-1; i++) {
                final int nextItem = i+1;
                ArrayQuestionsEditTexts.get(i).setOnEditorActionListener(new TextView.OnEditorActionListener() {

                    public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {

                        if ((event != null && (event.getKeyCode() == KeyEvent.KEYCODE_ENTER)) || (actionId == EditorInfo.IME_ACTION_NEXT)) {
                            ArrayQuestionsEditTexts.get(nextItem).requestFocus();

                        }
                        return false;
                    }
                });
           }

但是此解决方案无效。

尝试：

List<TextView> ArrayQuestionsEditTexts = new ArrayList<TextView>();

for(int i=0; i<5; i++){
    View to_add = inflater.inflate(R.layout.list_item_add_new_offer, options_layout,false);

    EditText question = (EditText) to_add.findViewById(R.id.editTextQuestion);

    question.setOnEditorActionListener(new TextView.OnEditorActionListener() {

        public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {

            if ((event != null && (event.getKeyCode() == KeyEvent.KEYCODE_ENTER)) || (actionId == EditorInfo.IME_ACTION_NEXT)) {
                ArrayQuestionsEditTexts.get(nextItem).requestFocus();

            }
            return false;
        }
    });

    ArrayQuestionsEditTexts.add(question);

    options_layout.addView(to_add);
}

或者，换句话说，当您执行第一个循环来增加布局时，为什么不还将侦听器附加到该循环中呢？而不是第二次循环添加侦听器？

根据官方doc：

您需要在视图上setTag（此处是编辑文本），然后需要使用findViewWithTag找到该视图，之后您需要通过requestFocus专注于编辑文本
