listview 多个item嵌套多个edittext 如何对相应item的edittext进行操作

要求是在listview的三个item中分别输入ip地址 每个item 有四个edittext
然后添加方法switch case position = 0时

edt_input1.addTextChangedListener(new TextWatcher() {
@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {

                }

                @Override
                public void onTextChanged(CharSequence s, int start, int before, int count) {

                }

                @Override
                public void afterTextChanged(Editable s) {
                    if (s.length() == 3) {                       
                        edt_input2.requestFocus();                           
                    }
                }
            });

在第一个item的第一个edittext输入之后 焦点并没有跳到第一个item的第二个edittext上 而是跳到了最后一个item的第二个edittext上，请问一下这里要如何处理？

这里不要用全局变量，这样子editText当前保存的对象是不能确定是那个item的，你这里的editText2应该是保存最后一个item的对象，所以才会滚动最后一个item上，试试用Holder

这样子看不出什么问题，贴一下getView()的代码

public class Adapter extends BaseAdapter {
private Context context = null;
private EditText editText1, editText2, editText3, editText4;
private RelativeLayout relativeLayout;

public Adapter(Context context) {
    this.context = context;

}

@Override
public int getCount() {
    return 3;
}

@Override
public Object getItem(int position) {
    return null;
}

@Override
public long getItemId(int position) {
    return 0;
}

@Override
public View getView(final int position, View convertView, final ViewGroup parent) {
    LayoutInflater inflater = (LayoutInflater) context
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    convertView = inflater.inflate(R.layout.item_layout, null);
    editText1 = (EditText) convertView.findViewById(R.id.edt1);
    editText2 = (EditText) convertView.findViewById(R.id.edt2);
    editText3 = (EditText) convertView.findViewById(R.id.edt3);
    relativeLayout = (RelativeLayout) convertView.findViewById(R.id.item_content);
    if (MainActivity.clickeditem == position) {
        relativeLayout.setBackgroundColor(Color.WHITE);
    }
    switch (position) {
        case 0:
            editText1.addTextChangedListener(new TextWatcher() {
                @Override
                public void beforeTextChanged(CharSequence s, int start, int count, int after) {

                }

                @Override
                public void onTextChanged(CharSequence s, int start, int before, int count) {

                }

                @Override
                public void afterTextChanged(Editable s) {
                    if (s.length() == 3) {
                        editText2.requestFocus();
                         //   editText1.focusSearch(View.FOCUS_DOWN);
                    }
                }
            });
            break;
        case 1:
            break;
    }
    return convertView;
}

}

private void setEdtIpInput() {

    EditeTextWatcher ipTextWatcher1 = new EditeTextWatcher(viewHolder.edt_input1);
    EditeTextWatcher ipTextWatcher2 = new EditeTextWatcher(viewHolder.edt_input2);
    EditeTextWatcher ipTextWatcher3 = new EditeTextWatcher(viewHolder.edt_input3);
    EditeTextWatcher ipTextWatcher4 = new EditeTextWatcher(viewHolder.edt_input4);

    viewHolder.edt_input1.addTextChangedListener(ipTextWatcher1);
    viewHolder.edt_input2.addTextChangedListener(ipTextWatcher2);
    viewHolder.edt_input3.addTextChangedListener(ipTextWatcher3);
    viewHolder.edt_input4.addTextChangedListener(ipTextWatcher4);

}

class EditeTextWatcher implements TextWatcher {
    public EditText mEditText;

    public EditeTextWatcher(EditText mEditText) {
        super();
        this.mEditText = mEditText;
    }

    @Override
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {

    }

    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) {
        Log.e("edt", "onTextChanged");
    }

    @Override
    public void afterTextChanged(Editable s) {
        if (s.length() == 3) {
            if (this.mEditText == viewHolder.edt_input1) {
                viewHolder.edt_input2.requestFocus();
            } else if (this.mEditText == viewHolder.edt_input2) {
                viewHolder.edt_input3.requestFocus();
            }
        } else if (s.length() == 1) {
            if (this.mEditText == viewHolder.edt_input3) {
                viewHolder.edt_input4.requestFocus();
            }
        } else if (s.length() == 0) {
            if (this.mEditText == viewHolder.edt_input4) {
                viewHolder.edt_input3.requestFocus();
            } else if (this.mEditText == viewHolder.edt_input3) {
                viewHolder.edt_input2.requestFocus();
            } else if (this.mEditText == viewHolder.edt_input2) {
                viewHolder.edt_input1.requestFocus();
            }
        }
    }
}

这个函数实在getview外面的，还有就是里面是没有viewHolder.的。。

在getViewe 里ditText1.addTextChangedListener(new EditeTextWatcher (Holder)）；哪里要用的Holder就把getView里的Holder对象传过去就行了
