問題描述

我有一個 ListView，每個項目中都有編輯文本，我想知道如何使 EditText 可編輯.如果我設置android:windowSoftInputMode="adjustPan" 進入清單，但僅在某些設備上.在某些設備上，軟鍵盤會覆蓋編輯文本.

I have a ListView with edit text in each items and I want to know how can I make the EditText editable.. It seems to work fine if I set the android:windowSoftInputMode="adjustPan" into the manifest but only on some devices. On some devices the soft keyboard covers the edittext.

另一方面，如果我沒有將 android:windowSoftInputMode="adjustPan" 放在清單中，則 EditText 在顯示軟鍵盤后失去焦點并且我必須多次觸摸 EditText 才能將其選中并可以在其中寫入.

On the other side, if I don't put android:windowSoftInputMode="adjustPan" in the manifest, the EditText looses focus after the soft keyboard is displayed and I have to touch the EditText multiple times to make it selected and can write in it.

請幫我解決這個問題.

注意:我看過這篇文章:ListView 內的可聚焦 EditText 沒有任何幫助，除此之外我還有其他問題

Note: I've seen this post: Focusable EditText inside ListView and nothing helped from there and I have totally other problem than that

我為此做了一個解決方法..也許會幫助某人

I made a workaround for this though.. maybe will help someone

public class EditTextListAdapter extends BaseAdapter {

    /* notes list */
    private ArrayList<SomeData> mSomeData = null;
    /* layout inflater instance */
    private LayoutInflater mInflater;
    /* activity context */
    private Context mContext;

    /* ensure that this constant is greater than the maximum list size */
    private static final int DEFAULT_ID_VALUE = -1;
    /* used to keep the note edit text row id within the list */
    private int mNoteId = DEFAULT_ID_VALUE;

    /**
     * EditTextListAdapter adapter class constructor
     *
     * @param context               activity context
     */
    public FirstTimesListAdapter(Context context) {

        /* get a layout inflater instance */
        mInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        /* load the data */
        mSomeData = SomeData.instance().getData(); 
        /* keep the context */
        mContext = context;
    }

    /**
     * Returns the selected item
     *
     * @return selected item
     */
    public int getSelectedItem() {
        return mSelectedItem;
    }

    public int getCount() {
        return mSomeData.size();
    }

    public Object getItem(int i) {
        return mSomeData.get(i);
    }

    public long getItemId(int i) {
        return i;
    }

    public View getView(final int index, View recycledView, ViewGroup viewGroup) {

        ViewHolder viewHolder;

        if (recycledView == null) {
            /* inflate the list item */
            recycledView = mInflater.inflate(R.layout.listview_item_with_edit_text, viewGroup, false);
            /* get link to the view holder views */
            viewHolder = new ViewHolder();
            viewHolder.note = (EditText) recycledView.findViewById(R.id.first_times_note);
            recycledView.setTag(viewHolder);
        } else {
            /* reuse the same views we load the first time */
            viewHolder = (ViewHolder) recycledView.getTag();
        }

        /* display some notes */
        viewHolder.note.setText(mSomeData.getNotes());

        /* if the last id is set, the edit text from this list item was pressed */
        if (mNoteId == index) { 

            /* make the edit text recive focus */
            viewHolder.note.requestFocusFromTouch();
            /* make the edit text's cursor to appear at the end of the text */
            viewHolder.note.setSelection(viewHolder.note.getText().length());

            /* reset the last id to default value */
            mNoteId = DEFAULT_ID_VALUE;
        }

        /* set a touch listener on the edit text just to record the index of the edit text that was pressed */
        viewHolder.note.setOnTouchListener(new View.OnTouchListener() {
            public boolean onTouch(View view, MotionEvent motionEvent) {
                if (motionEvent.getAction() == MotionEvent.ACTION_UP) {
                    /* get the index of the touched list item */
                    mNoteId = index;
                }
                return false;
            }
        });

        return recycledView;
    }

    static class ViewHolder {        
        /* note input */
        EditText note;
    }

}
