Question

我有Fragment在RelativeLayout中夸大了onCreateView()。我在ActionBar中有一个按钮，我想在每次点击时向视图添加EditText窗口小部件。我制作了ArrayList EditTexts个EditText，其中添加了自定义EditText类。如何为ArrayList中的所有OnTouchListener字段充气？有没有办法通过引用数组的索引来膨胀。注意我最终想为每个领域添加public class SomeFragment extends Fragment { private View v; private List<EditText> editTextList = new ArrayList<EditText>(); private int n = 0; private View.OnTouchListener TouchHandler; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setRetainInstance(true); setHasOptionsMenu(true); } @Override public void onCreateOptionsMenu(Menu menu, MenuInflater inflater){ super.onCreateOptionsMenu(menu, inflater); inflater.inflate(R.menu.edit_actionbar, menu); } public boolean onOptionsItemSelected(MenuItem item){ switch(item.getItemId()){ case R.id.menu_item_add_text: n=n+1; editTextList.add(editText(n)); return true; default: return super.onOptionsItemSelected(item); } } private EditText editText(int id){ EditText editText = new EditText(getActivity()); editText.setId(id); editText.setOnTouchListener(TouchHandler); editTextList.add(editText); return editText; } @Override public View onCreateView(LayoutInflater inflater, ViewGroup parent, Bundle savedInstanceState) { v = inflater.inflate(R.layout.edit_fragment, parent, false); TouchHandler = new View.OnTouchListener() { public boolean onTouch(View v, MotionEvent ev) { // ....................... }; return v; } }。

全球维护一个柜台，

private int counter;

view.setOnClickListener(new OnClickListener){
    @override
    public void onClick(View view){
        EditText editText = editTextList.get(counter);
        // you can add the editText to the view you want
        counter++;
    }
}

希望这可以帮助你：）

我最终做了这个问题的回答中提出的建议Adding array of textviews dynamically to linear layout。

在OnCreateView中：

    ViewGroup.LayoutParams lp = new ViewGroup.LayoutParams( ViewGroup.LayoutParams.MATCH_PARENT,    ViewGroup.LayoutParams.WRAP_CONTENT);
    pairs=new EditText[9];
    for(int l=0; l<9; l++)
    {
        pairs[l] = new EditText(getActivity() );
        pairs[l].setTextSize(15);
        pairs[l].setLayoutParams(lp);
        pairs[l].setId(l);
        pairs[l].setText((l + 1));
        pairs[l].setFocusableInTouchMode(false);
        pairs[l].setOnTouchListener(new MyTouchListener());
    }

在onOptionsItemselected：

 private int counter;

 case R.id.menu_item_add_text:

     myLayout.addView(pairs[counter]);
     counter++;

 return true;

创建并添加EditText小部件，以便在单击按钮时查看
