android - 从 Android 中的字符串资源填充 listView

Question

我正在尝试从 Android 中的字符串 XML 文件中定义的字符串资源填充 ListView 。我没有收到任何错误，但是当我运行应用程序时，它要求我强制关闭。我在日志猫管理器中收到以下错误 03-26 01:04:42.903: E/dalvikvm(205): 无法打开堆栈跟踪文件 '/data/anr/traces.txt': 权限被拒绝

这是我的程序的代码

public class MainMenu extends Activity {
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.menu);

    /*ListView menu = (ListView) findViewById(R.id.ListView_Menu);

    String[] items = { getResources().getString(R.string.today_bd),getResources().getString(R.string.Add_bd),
            getResources().getString(R.string.msg_tmplate),getResources().getString(R.string.credits),
            getResources().getString(R.string.help)
    };

    ArrayAdapter<String> adapt = new ArrayAdapter<String>(this,R.layout.menu,items);

    menu.setAdapter(adapt);*/
    ListView menuList = (ListView) findViewById(R.id.ListView_Menu);
    String[] items = { getResources().getString(R.string.today_bd),
            getResources().getString(R.string.add_bd),
            getResources().getString(R.string.msg_tmplate),
            getResources().getString(R.string.credits),
            getResources().getString(R.string.help)
            };

    ArrayAdapter<String> adapt = new ArrayAdapter<String>(this, R.layout.menu, items);
    menuList.setAdapter(adapt);
    menuList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        public void onItemClick(AdapterView<?> parent, View itemClicked, int position, long id) {

            TextView textView = (TextView) itemClicked;
            String strText = textView.getText().toString();
            if (strText.equalsIgnoreCase(getResources().getString(R.string.today_bd))) {

                //startActivity(new Intent(QuizMenuActivity.this, QuizGameActivity.class));
            } else if (strText.equalsIgnoreCase(getResources().getString(R.string.add_bd))) {
                // Launch the Help Activity
                //startActivity(new Intent(QuizMenuActivity.this, QuizHelpActivity.class));
            } else if (strText.equalsIgnoreCase(getResources().getString(R.string.msg_tmplate))) {
                // Launch the Settings Activity
                //startActivity(new Intent(QuizMenuActivity.this, QuizSettingsActivity.class));
            } else if (strText.equalsIgnoreCase(getResources().getString(R.string.credits))) {
                // Launch the Scores Activity
               // startActivity(new Intent(QuizMenuActivity.this, QuizScoresActivity.class));
            }
            else if (strText.equalsIgnoreCase(getResources().getString(R.string.help))) {
                // Launch the Scores Activity
               // startActivity(new Intent(QuizMenuActivity.this, QuizScoresActivity.class));
            }
        }


        //public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
                //long arg3) {
            // TODO Auto-generated method stub

        //}
    });




}

请帮忙!!!

您正在调用的ArrayAdapter 构造函数采用三个参数——您已经正确地获得了第一个和第三个参数，但第二个参数想要成为item 布局。

textViewResourceId 包含在实例化 View 时使用的 TextView 的布局文件的资源 ID。

尝试使用 android.R.layout.simple_list_item_1 应该会有帮助...

ArrayAdapter<String> adapt = 
  new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, items);
