java - Android错误: Syntax error on token "}",删除此 token

Question

我有以下代码，但似乎无法弄清楚为什么会收到上述错误消息。我显然知道这意味着什么，但我检查了括号，它们对我来说似乎是正确的。我正在运行 ADT 21.1.0。到目前为止，我已经尝试过重新启动 Eclipse；重新启动我的电脑；并重建该项目。

package cct.mad.lab;

import android.app.ListActivity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.TextView;
import android.widget.Toast;

public class WalkList extends ListActivity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        // storing string resources into Array
        String[] players = getResources().getStringArray(R.array.players);

        // Binding resources Array to ListAdapter
        this.setListAdapter(new ArrayAdapter<String>(this, R.layout.list_item, R.id.label, players));
    }

    protected void onListItemClick (ListView 1, View v, int position, long id) {
        String item = (String) getListAdapter().getItem(position);
    Toast.makeText(this, item + " selected", Toast.LENGTH_LONG).show();
    }
}

Answer 1

这几乎肯定是因为 onListItemClick 定义中定义的标识符无效。

将 onListItemClick 中的 ListView 标识符从 1 更改为其他内容(有效标识符)。

来自jls-3.8 :

An identifier is an unlimited-length sequence of Java letters and Java digits, the first of which must be a Java letter.

有关 Java 字母的更多信息:

The "Java letters" include uppercase and lowercase ASCII Latin letters A-Z (\u0041-\u005a), and a-z (\u0061-\u007a), and, for historical reasons, the ASCII underscore (_, or \u005f) and dollar sign ($, or \u0024). The $ character should be used only in mechanically generated source code or, rarely, to access pre-existing names on legacy systems.
