ListView强制关闭

标签： android

我正在编写一个将文件放入文件夹的类，并在列表视图中显示内容。当我运行此活动时应用程序强制关闭...我调试了一段时间，并通过logcat搜索，我找不到问题... 

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    File root = new File(Environment.getExternalStorageDirectory(), "Notes");
    if(!root.exists()){
        root.mkdirs();
    }
    setListAdapter(new ArrayAdapter<String>(this, R.layout.folders, buildDirArray(root)));

      ListView lv = getListView();
      lv.setTextFilterEnabled(true);

      lv.setOnItemClickListener(new OnItemClickListener() {
        public void onItemClick(AdapterView<?> parent, View view,
            int position, long id) {
          // When clicked, show a toast with the TextView text
          Toast.makeText(getApplicationContext(), ((TextView) view).getText(),
              Toast.LENGTH_SHORT).show();
        }
      });
    }
public String[] buildDirArray(File dir){
int temp = dir.list().length;
String[] tm = dir.list();
String[] tmp = new String[temp];
for(int i=1;i==dir.list().length;i++){
    tmp[i]=tm[i];
}

    return tmp;

}

非常感谢任何帮助...... Logcat数据：

2 个答案:

答案 0 :(得分：3)

日志说：

You have to add  <uses-permission android:name="android.permission.WAKE_LOCK"/> to your AndroidManifest.xml !

哦，有些行进一步向下，日志中还有一个错误：

android.content.ActivityNotFoundException: Unable to find explicit activity class {com.momentum.xpad/com.momentum.xpad.folders}; have you declared this activity in your AndroidManifest.xml?

答案 1 :(得分：0)

android.content.ActivityNotFoundException：无法找到显式活动类{com.momentum.xpad / com.momentum.xpad.folders};你有没有在AndroidManifest.xml中声明这个活动？

你有没有在你的清单中宣布它？
