如何得到一个ListView内的所有的EditText值有的、ListView、EditText

2023-09-05 10:27:49 作者:酷炫老祖宗

我想获得的所有的EditText元素是我的ListView里面present的所有值。 这是我的code:

 最终的ListView editorList =(ListView控件)findViewById(R.id.editorList);
        最后EditorAdapter适配器=新EditorAdapter(上下文数据);
        editorList.setAdapter(适配器);


        按钮commitButton =(按钮)findViewById(R.id.commit_button);
        commitButton.setOnClickListener(新View.OnClickListener(){

            @覆盖
            公共无效的onClick(视图v){
                // TODO自动生成方法存根
                尝试{
                    清单//System.out.println("Size:+ editorList.getChildCount());
                    的for(int i = 0; I< data.size();我++){
                        的System.out.println(列出的大小:+ data.size());

                        的EditText值= adapter.getItem(ⅰ);
                        字符串为PropertyValue = value.getText()的toString()。
                        的System.out.println(为PropertyValue:+为PropertyValue);


                    }
                }赶上(例外五){
                    e.printStackTrace();
                }
            }
        });
 

这是我的适配器类:

 包in.omerjerk preferenceseditor。

公共EditorAdapter(上下文的背景下,ArrayList的< HashMap的<字符串,字符串>>数据){

    mHolders =新的EditText [data.size()];

}

        持有人=新ViewHolder();
        convertView = LayoutInflater.from(上下文).inflate(R.layout.row_edit_string,空,假);
        holder.editPropertyValue =(EditText上)convertView.findViewById(R.id.propertyValue);
        holder.propertyName =(TextView中)convertView.findViewById(R.id.propertyName);

        holder.propertyName.setText(data.get(位置)获得(propertyName的));
        holder.editPropertyValue.setText(data.get(位置)获得(propertyName的));
        convertView.setTag(保持器);



    }其他{
        的System.out.println(转换VIEW NOT NULL);
        支架=(ViewHolder)convertView.getTag();
        holder.propertyName.setText(data.get(位置)获得(propertyName的));
        holder.editPropertyValue.setText(data.get(位置)获得(propertyName的));
        convertView.setTag(保持器);
        mHolders [位置] =新的EditText(上下文);
        mHolders [位置] = holder.editPropertyValue;
    }

    返回convertView;
}

}
 

我收到我的输出奇怪的错误。所述mHolders阵列只包含高达6-7元件和这些元件重复整个阵列在。我能够得到的EditText的值,但该错误是不正确的。

动态ListView中item的EditText控件

I want to get all the values of all the EditText elements that are present inside my ListView. This is my code :

final ListView editorList = (ListView) findViewById(R.id.editorList);
        final EditorAdapter adapter = new EditorAdapter(context, data);
        editorList.setAdapter(adapter);


        Button commitButton = (Button) findViewById(R.id.commit_button);
        commitButton.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                try{
                    //System.out.println("Size of List : " + editorList.getChildCount());
                    for(int i =0;i< data.size() ;i++){
                        System.out.println("Size of List : " + data.size());

                        EditText value = adapter.getItem(i);
                        String propertyValue = value.getText().toString();
                        System.out.println("PropertyValue : " + propertyValue);


                    }
                } catch (Exception e){
                    e.printStackTrace();
                }
            }
        });

This is my Adapter class :

package in.omerjerk.preferenceseditor;


public class EditorAdapter extends BaseAdapter {

Context context;
ArrayList<HashMap<String,String>> data;
EditText[] mHolders;

public EditorAdapter(Context context, ArrayList<HashMap<String,String>> data){

    this.context = context;
    this.data = data;
    System.out.println("No . of items in nodes"+data.size());
    mHolders = new EditText[data.size()];

}

@Override
public int getCount() {
    // TODO Auto-generated method stub
    return data.size();
}

@Override
public EditText getItem(int pos) {
    // TODO Auto-generated method stub
    return mHolders[pos];
}

@Override
public long getItemId(int pos) {
    // TODO Auto-generated method stub
    return pos;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    // TODO Auto-generated method stub
    ViewHolder holder;
    if(convertView==null){
        System.out.println("CONVERT VIEW IS NULL");
        holder = new ViewHolder();
        convertView = LayoutInflater.from(context).inflate(R.layout.row_edit_string,null,false);
        holder.editPropertyValue = (EditText) convertView.findViewById(R.id.propertyValue);
        holder.propertyName = (TextView) convertView.findViewById(R.id.propertyName);

        holder.propertyName.setText(data.get(position).get("propertyName"));
        holder.editPropertyValue.setText(data.get(position).get("propertyName"));
        convertView.setTag(holder);



    }else{
        System.out.println("CONVERT VIEW NOT NULL");
        holder = (ViewHolder) convertView.getTag();
        holder.propertyName.setText(data.get(position).get("propertyName"));
        holder.editPropertyValue.setText(data.get(position).get("propertyName"));
        convertView.setTag(holder);
        mHolders[position] = new EditText(context);
        mHolders[position] = holder.editPropertyValue;
    }

    return convertView;
}

}

I'm getting strange error in my output. The mHolders array only contain upto 6-7 elements and these elements are repeated in the entire array. I'm able to get the values of EditText but the error is not correct.
