问题描述

我使用的列表视图随着包含的ImageView,TextView中和3键(插入,更新,删除)的要求是自定义适配器是叫广播接收器内的每个时间,直到IntentFilter的匹配,我也自定义适配器设置onclicklistener按钮的底座适配器的getView方法。

的问题是,列表视图按钮,只有最后一排只有clickable..But我希望所有行的所有按钮必须点击。

任何人都可以给我建议或任何想法,我可以如何进行该问题。

 公开查看getView(最终诠释的立场,观点来看,一个ViewGroup父){
    // TODO自动生成方法存根

            POS =位置;

    如果(查看== NULL)
    {
        LayoutInflater充气=(LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        鉴于= inflater.inflate(R.layout.device_name,父母,假);
    }

    TextView的text_view =(TextView中)view.findViewById(R.id.textview_deviceName);

    ImageView的image_view =(ImageView的)view.findViewById(R.id.imageView1);

    text_view.setText(strDeviceName [位置]);
    如果(strMajorDevice [位置] .equalsIgnoreCase(手机))
    {
        image_view.setImageResource(int_image [0]);
    }
    其他
    {
        image_view.setImageResource(int_image [1]);
    }
    btnAdd =(按钮)view.findViewById(R.id.btn_add);
    为btnUpdate =(按钮)view.findViewById(R.id.btn_update);
    btnDelete =(按钮)view.findViewById(R.id.btn_delete);

    btnAdd.setOnClickListener(本);
    btnUpdate.setOnClickListener(本);
    btnDelete.setOnClickListener(本);
    返回查看;
}

@覆盖
公共无效的onClick(视图v){
    // TODO自动生成方法存根
    如果(V == btnAdd)
    {
        Toast.makeText(背景下,ADD,Toast.LENGTH_LONG).show();
        意向意图=新的意图(背景下,MaterDeviceFormActivity.class);
        intent.putExtra(按钮,增加);
        intent.putExtra(DEVICE_ADDRESS,strDviceAddess [POS]);
        context.startActivity(意向);

    }
    否则,如果(V ==为btnUpdate)
    {
        Toast.makeText(上下文中,数据库,Toast.LENGTH_LONG).show();
        意向意图=新的意图(背景下,MaterDeviceFormActivity.class);
        intent.putExtra(按钮,更新);
        intent.putExtra(DEVICE_ADDRESS,strDviceAddess [POS]);
        context.startActivity(意向);
    }
    否则,如果(V == btnDelete)
    {
        Toast.makeText(上下文,DELETE,Toast.LENGTH_LONG).show();
        意向意图=新的意图(背景下,MaterDeviceFormActivity.class);
        intent.putExtra(键,删除);
        intent.putExtra(DEVICE_ADDRESS,strDviceAddess [POS]);
        context.startActivity(意向);
    }
}
 

解决方案

 私人上下文的背景下;

公共ListViewAdapter(上下文的背景下,的String [] dateValues​​,字符串[] creditAmountValues​​,字符串[] closingBalanceValues​​,字符串[] currentAmountValues​​)
{
    超(背景下,R.layout.transactionlayout,dateValues​​);
    this.context =背景;

}

 @覆盖
  公共查看getView(最终诠释的立场,观点convertView,ViewGroup中父){
    LayoutInflater充气=(LayoutInflater)上下文
        .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    查看rowView = inflater.inflate(R.layout.transactionlayout,父母,假);


         ((按钮)rowView.findViewById(R.id.transactions_historyButtonID))。setOnClickListener(新OnClickListener(){

        @覆盖
        公共无效的onClick(视图v){
            Toast.makeText(上下文,+的位置,4000).show();
        }
    });

    返回rowView;
  }
 

获得使用用打气筒行视图。这是工作。让我知道如果u有任何的怀疑。

I am using Listview With custom Adapter which contain imageview,textview and 3 button (insert,update,delete)requirement is that custom adapter is call every time inside BROADCAST receiver until intentfilter matched and i also set onclicklistener of button in getView method of base adapter.

The problem is that only the last row of listview button is only clickable..But i want all the button of all row must clickable.

Can anybody give me suggestion or any idea how I can proceed for that problem.

public View getView(final int position, View view, ViewGroup parent) {
    // TODO Auto-generated method stub

            pos=position;

    if(view==null)
    {
        LayoutInflater inflater=(LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        view=inflater.inflate(R.layout.device_name, parent, false);
    }

    TextView text_view=(TextView)view.findViewById(R.id.textview_deviceName);

    ImageView image_view=(ImageView)view.findViewById(R.id.imageView1);

    text_view.setText(strDeviceName[position]);
    if(strMajorDevice[position].equalsIgnoreCase("phone"))
    {
        image_view.setImageResource(int_image[0]);
    }
    else
    {
        image_view.setImageResource(int_image[1]);
    }
    btnAdd=(Button)view.findViewById(R.id.btn_add);
    btnUpdate=(Button)view.findViewById(R.id.btn_update);
    btnDelete=(Button)view.findViewById(R.id.btn_delete);

    btnAdd.setOnClickListener(this);
    btnUpdate.setOnClickListener(this);
    btnDelete.setOnClickListener(this);
    return view;
}

@Override
public void onClick(View v) {
    // TODO Auto-generated method stub
    if(v==btnAdd)
    {
        Toast.makeText(context, "ADD", Toast.LENGTH_LONG).show();
        Intent intent = new Intent(context,MaterDeviceFormActivity.class);
        intent.putExtra("button","add");
        intent.putExtra("device_address", strDviceAddess[pos]);
        context.startActivity(intent);

    }
    else if(v==btnUpdate)
    {
        Toast.makeText(context, "UPDATE", Toast.LENGTH_LONG).show();
        Intent intent = new Intent(context,MaterDeviceFormActivity.class);
        intent.putExtra("button","update");
        intent.putExtra("device_address", strDviceAddess[pos]);
        context.startActivity(intent);
    }
    else if(v==btnDelete)
    {
        Toast.makeText(context, "DELETE", Toast.LENGTH_LONG).show();
        Intent intent = new Intent(context,MaterDeviceFormActivity.class);
        intent.putExtra("button","delete");
        intent.putExtra("device_address", strDviceAddess[pos]);
        context.startActivity(intent);
    }
}
解决方案
private Context context;

public ListViewAdapter(Context context, String[] dateValues,String[] creditAmountValues,String[] closingBalanceValues,String[] currentAmountValues)
{
    super(context, R.layout.transactionlayout, dateValues);
    this.context = context;

}

 @Override
  public View getView(final int position, View convertView, ViewGroup parent) {
    LayoutInflater inflater = (LayoutInflater) context
        .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View rowView = inflater.inflate(R.layout.transactionlayout, parent, false);


         ((Button)rowView.findViewById(R.id.transactions_historyButtonID)).setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            Toast.makeText(context, ""+position, 4000).show();
        }
    });

    return rowView;
  }

get the use of row view using inflater. this is working. let me know if u have any doubts.
