Android 安卓输入不受尊重

我有一个列表视图，每行有一个EditText。EditText应该收集数字值，所以我尝试关闭字母键盘，只允许用户看到数字键盘

但是，当填充listview并单击列表中的任何EditText时，会出现数字键盘，但随后很快就会被完整的qwerty键盘取代，用户必须切换回数字以输入数字

我尝试过各种编程组合，如：

mPercent.setInputType(InputType.TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_VARIATION_NORMAL);

以及XML的多种组合，如

android:inputType="phone"

或

但是，无论组合如何，它们的键盘总是快速切换回qwerty并关闭数字键

我想可能是短信观察者的问题。我使用textwatcher来指示键入的内容。我删除它，添加该行edittext中的任何文本，然后添加textwatcher

这是我的自定义适配器的核心：

public View getView(final int position, View inView, ViewGroup parent) {
        ViewHolder holder = null;

        if (inView == null) {
            LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            inView = inflater.inflate(mLayoutResource, null);
            holder = new ViewHolder();
            holder.mPercent = (EditText) inView.findViewById(R.id.percent);
            holder.mMaterial = (TextView) inView.findViewById(R.id.name);
            inView.setTag(holder);
        } else {
            holder = (ViewHolder) inView.getTag();
        }

        mMaterial.moveToPosition(position);

        holder.mPercent.setInputType(InputType.TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_VARIATION_NORMAL);

// remove textwatcher on percentage
        holder.mPercent.removeTextChangedListener(percentWatcher);

        // insert the percentage for this row
        final String material = mMaterial.getString(mMaterial.getColumnIndex(OptionsProvider.OPTIONS_DATA));
        final EditText percent = holder.mPercent;

        percent.setTag(material);   // use material and position as keys into which of the many edittexts the textwatcher is watching
        percent.setId(position);

        holder.mMaterial.setText(material);

        // persist any text the user may have typed in the comment box
        if (percentages.containsKey(material)) {
            percent.setText(percentages.get(material));
        }
        else {
            percent.setText("");
        }

        // turn on textwatcher
        percentWatcher = new TextWatcher() {
            @Override
            public void onTextChanged(CharSequence s, int start, int before, int count) {
                // save this text and the position in which is resides.
                // if the user scrolls before pressing send, only this position should
                // contain the text
                String text = percent.getText().toString().trim();
                if (text.length() > 0) {
                    if ((position == percent.getId() &&
                            (material.equals( percent.getTag().toString())))) {
                        percentages.put(material, text);
                        Log.d(TAG, "Percentage inserted "+material+"="+text);
                    }
                }
            }

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

            // force the EditText to stay with 3 digits (max of 100%)
            @Override
            public void afterTextChanged(Editable s) {
                if (s.length() > 0) {
                    int pct = Integer.parseInt(s.toString());
                    Log.d(TAG, " Material "+(String) percent.getTag()+ " = "+pct);
                }
            }
        };

        // add the textwatcher back to the edittext
        holder.mPercent.addTextChangedListener(percentWatcher);

有人知道删除/添加textwatcher是否会破坏输入类型吗？这是我应该探索的一条路径，以找出为什么键盘总是回到qwerty？

可能是ListView窃取了焦点。尝试将此添加到ListView

XML

android:descendantFocusability="afterDescendants"

或在Java中

listView.setDescendantFocusability(ViewGroup.FOCUS_AFTER_DESCENDANTS);

令人惊叹的！在XML中放置属性是有效的。但万一有人想知道，用编程的方式来做同样有效。非常感谢，波扬！它应该在Java中工作，毕竟您的XML是编译成Java的：）顺便说一句，没问题。

listView.setDescendantFocusability(ViewGroup.FOCUS_AFTER_DESCENDANTS);
