問題描述

嘗試將 onClickListener 添加到我的 listView 中的項目，但我收到一條錯誤消息:View 類型中的方法 setOnClickListener(View.OnClickListener) 不適用于參數(新 DialogInterface.OnClickListener(){})"就行了:

Attempting to add an onClickListener to items in my listView and I'm getting an error stating: "The method setOnClickListener(View.OnClickListener) in the type View is not applicable for the arguments (new DialogInterface.OnClickListener(){})" on the line:

 holder.imageView.setOnClickListener(new OnClickListener() {

本文作者提到以下幾點:

The author of this article mentioned the following:

In your custom adapter class, you can try this code inside getView() method
[java]holder.imageView.setOnClickListener(new OnClickListener() {   
@Override
public void onClick(View v) {
Toast.makeText(context, "Clicked on image", Toast.LENGTH_LONG).show();
}
});[/java]

似乎我可能需要修改我當前的實現 - 我只是不確定具體如何.

It seems as if I might need to modify my current implementation - I'm just not sure exactly how.

public View getView(int position, View convertView, ViewGroup parent) {
        ViewHolder holder;
        LayoutInflater inflater = context.getLayoutInflater();
        if (convertView == null) {
            convertView = inflater.inflate(R.layout.list_item2, null);
            holder = new ViewHolder();
            holder.txtSuccess = (TextView) convertView
                    .findViewById(R.id.success);
            holder.txtCmd = (TextView) convertView.findViewById(R.id.cmd);
            holder.txtPrice = (TextView) convertView.findViewById(R.id.price);
            holder.imageView = (ImageView) convertView
                    .findViewById(R.id.thumbnail);
            convertView.setTag(holder);
            holder.imageView.setOnClickListener(new OnClickListener() {

                public void onClick(View v) {
                    Toast.makeText(context, "Clicked on image",
                            Toast.LENGTH_LONG).show();
                }

推薦答案

你可能有錯誤的 import.檢查您是否導入了 DialogInterface.OnClickListener.您仍然可以通過這種方式顯式強制參數:

you probably have the wrong import. Check if you imported DialogInterface.OnClickListener. Still you can explicitly force the parameter this way:

holder.imageView.setOnClickListener(new View.OnClickListener() {
   public void onClick(View v) {
         Toast.makeText(context, "Clicked on image",
                Toast.LENGTH_LONG).show();
   }
