Question

我已经多次看到这个问题了，我认为这并不难解决;我还是试了好几个小时，不知道它是如何运作的。

简单问题：我在listView中有2个EditText，当我触摸它们的字段时，它们都会立即松散焦点。

必须是一些层次结构的东西。实际上我可以用adjustpan属性修复它，但是当softKeyboard打开时我的listView不再滚动。

这是我的代码：

package com.android.activity;

import android.content.Context;
import android.database.Cursor;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.CursorAdapter;
import android.widget.EditText;
import android.widget.TextView;

public class NotesCursorAdapter extends CursorAdapter{

    private Context context;
    //  private Cursor cursor;
    private int addNoteTopPosition;
    private int addNoteBottomPosition;
    private LayoutInflater inflater;
    private boolean deleteMode = false;

    private static final int TYPE_ITEM = 0;
    private static final int TYPE_ADD_NOTE_BOTTOM = 1;
    private static final int TYPE_ADD_NOTE_TOP = 2;
    private static final int TYPE_MAX_COUNT = TYPE_ADD_NOTE_TOP + 1;

    public NotesCursorAdapter (Context context, Cursor cursor, int flag, boolean enableDelete){
        super(context, cursor);
        this.context = context;
        addNoteTopPosition = 0;
        addNoteBottomPosition = cursor.getCount()+1;

        inflater = LayoutInflater.from(this.context);

        deleteMode = enableDelete;

    }

    @Override
    public int getCount() {  
        return super.getCount() + 2;
    } 

    @Override
    public View getView(int position, View convertView, ViewGroup parent){
        ViewHolder holder = null;
        int type = getItemViewType(position);
        if (convertView == null) {
            holder = new ViewHolder();
            switch (type) {

            case TYPE_ADD_NOTE_TOP:
                convertView = inflater.inflate(R.layout.add_note_top, null);
                holder.view = (EditText)convertView.findViewById(R.id.add_note_top_id);
                break;
            case TYPE_ITEM:
                convertView = inflater.inflate(R.layout.row_note, null);
                holder.delete = (Button)convertView.findViewById(R.id.delete);
                if (deleteMode){
                    holder.delete.setVisibility(View.VISIBLE);
                }else{
                    holder.delete.setVisibility(View.GONE);
                }
                holder.delete.setOnClickListener(new OnClickListener() {

                    @Override
                    public void onClick(View v) {

                    }
                });

                holder.view = (TextView)convertView.findViewById(R.id.note);
                getCursor().moveToPosition(position - 1);
                ((TextView) holder.view).setText(getCursor().getString(getCursor().getColumnIndex("content_note")));
                break;
            case TYPE_ADD_NOTE_BOTTOM:
                convertView = inflater.inflate(R.layout.add_note_bottom, null);
                holder.view = (EditText)convertView.findViewById(R.id.add_note_bottom_id);
                break;
            }
            convertView.setTag(holder);
        } else {
            holder = (ViewHolder)convertView.getTag();
        }

        return convertView;
    }

    @Override
    public int getItemViewType(int position) {
        int type;
        if (position == addNoteTopPosition){
            type = TYPE_ADD_NOTE_TOP;
        } else if (position == addNoteBottomPosition){
            type = TYPE_ADD_NOTE_BOTTOM;
        }else {
            type = TYPE_ITEM;
        }
        return type;
    }

    @Override
    public int getViewTypeCount() {
        return TYPE_MAX_COUNT;
    }

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

    public static class ViewHolder {
        public View delete;
        public View view;
    }

    @Override
    public void bindView(View view, Context context, Cursor cursor) {

    }

    @Override
    public View newView(Context context, Cursor cursor, ViewGroup parent) {
        return null;
    }

}

我认为我认为重要的是，如果你们需要一些更像活动代码或其他东西，请问。

感谢阅读。

尝试设置

android:windowSoftInputMode="adjustPan"

表示您在AndroidManifest.xml中的活动

Android：为什么我的EditText字段失去焦点？
