In app I have a Listactivity which has an adapter with TextView and Button(labeled delete). Now I want to remove corresponding Button clicked item. please check the code and suggest???? `

public class MySimpleArrayAdapter extends ArrayAdapter<String> implements OnClickListener {
    private final Activity context;
    private final String[] names;
    private Button deleteButton= null;
    public MySimpleArrayAdapter(Activity context, String[] names) {
        super (context, R.layout.imagelistlayout, names);
        this.context = context;
        this.names = names;

    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        LayoutInflater inflater = context.getLayoutInflater();
        View rowView = inflater.inflate(R.layout.imagelistlayout, null, true);
        deleteButton= (Button)rowView.findViewById(R.id.delete_bn);
        deleteButton.setTag(position);
        TextView textView = (TextView) rowView.findViewById(R.id.label);
        textView.setText(names[position]);
        deleteButton.setOnClickListener(this); 
        return rowView;

    }

    @Override
    public void onClick(View convertView) {

    }

}` 

我想知道我怎么能删除其按钮被点击的项目。

I want to know how can I delete the item whose button has been clicked.

推荐答案

刚刚处理里面getview点击监听器，你使用findviewbyid找到按钮

just handle on click listener inside getview where you find the button using findviewbyid

这将处理当前行按钮点击

this will handle the current row button click

public class MySimpleArrayAdapter extends ArrayAdapter<String> implements OnClickListener {
    private final Activity context;
    private final String[] names;
    private Button deleteButton= null;
    public MySimpleArrayAdapter(Activity context, String[] names) {
        super (context, R.layout.imagelistlayout, names);
        this.context = context;
        this.names = names;

    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        LayoutInflater inflater = context.getLayoutInflater();
        View rowView = inflater.inflate(R.layout.imagelistlayout, null, true);
        deleteButton= (Button)rowView.findViewById(R.id.delete_bn);
        deleteButton.setTag(position);
        TextView textView = (TextView) rowView.findViewById(R.id.label);
        textView.setText(names[position]);
       deleteButton.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View arg0) {
                //try to hide textview or something it may help
            }
        });
        return rowView;

    }

}`
