logcat的错误：＆QUOT; addView（查看，的LayoutParams）不支持适配器视图＆QUOT;在ListView [英] Logcat error: "addView(View, LayoutParams) is not supported in AdapterView" in a ListView

问题描述

我正在为Android应用程序和一些我需要的是，它显示了SD卡中的所有文件和目录的列表，它必须能够移动通过不同的目录。我发现一个很好的教程在anddev 。我修改了一些东西，所以在SD卡上的应用程序移动，而不是在Android的根目录下，但其余大部分是相同的。

I'm doing an application for Android and something I need is that it shows a list of all files and directories in the SD Card and it has to be able to move through the different directories. I found a good tutorial in anddev. I modified a few things so the application moves in the SD Card and not in Android root Directories but the rest is mostly the same.

这是我对活动的xml文件：

This is my xml file for the activity:

    <?xml version="1.0" encoding="utf-8"?>
<ListView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@id/android:list"       
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
    <TextView 
        android:layout_width="fill_parent"
        android:layout_height="wrap_content" />
</ListView>

这是code的活动：

And this is the code for the Activity:

    import hackreatorz.cifrador.R;

import java.io.File;
import java.util.ArrayList;

import android.app.ListActivity;
import android.content.res.Configuration;
import android.os.Bundle;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.Toast;

public class ArchivosSD extends ListActivity {

    private ArrayList<String> directoryEntries = new ArrayList<String>();
    private File currentDirectory = new File("/sdcard/");

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        browseToSD();
    }

    @Override
    public void onConfigurationChanged(Configuration newConfig) {
        super.onConfigurationChanged(newConfig);
    }

    private void browseToSD() {
        browseTo(new File("/sdcard/"));
    }

    private void upOneLevel() {
         if(this.currentDirectory.getParent() != null)
             this.browseTo(this.currentDirectory.getParentFile());
    }

    private void browseTo(final File directory) {
        if (directory.isDirectory()) {
                this.currentDirectory = directory;
                fill(directory.listFiles());
        } else {
                Toast.makeText(ArchivosSD.this, this.directoryEntries.get(this.getSelectedItemPosition()), Toast.LENGTH_SHORT).show();
                }
    }

    private void fill(File[] files) {
        this.directoryEntries.clear();
        this.directoryEntries.add(getString(R.string.current_dir));
        if(this.currentDirectory.getParent() != null)
            this.directoryEntries.add(getString(R.string.up_one_level));
            int currentPathStringLength = (int) this.currentDirectory.getAbsoluteFile().length();
            for (File file : files) {
                this.directoryEntries.add(file.getAbsolutePath().substring(currentPathStringLength));           
            }
        setListAdapter(new ArrayAdapter<String>(this, R.layout.archivos_sd, this.directoryEntries));
    }   

    @Override
    protected void onListItemClick(ListView l, View v, int position, long id) {
        int selectionRowID = (int) this.getSelectedItemPosition();
        String selectedFileString = this.directoryEntries.get(selectionRowID);
        if (selectedFileString.equals(".")) {
            this.browseToSD();
        } else if(selectedFileString.equals("..")) {
            this.upOneLevel();
        } else {
            File clickedFile = null;
            clickedFile = new File(this.currentDirectory.getAbsolutePath() + this.directoryEntries.get(selectionRowID));
            if(clickedFile != null)
                this.browseTo(clickedFile);
            }
    }
}

我不明白在Eclipse中的任何错误，但运行在我的手机应用程序，当我得到一个强制关闭，当我看着我的logcat看到以下内容：

I don't get any errors in Eclipse, but I get a Force Close when running the application on my phone and when I look at Logcat I see the following:

01-01 23：30：​​29.858：ERROR / AndroidRuntime（14911）：致命异常：主要的 * 01-01 23：30：​​29.858：ERROR / AndroidRuntime（14911）：java.lang.UnsupportedOperationException：addView（查看，的LayoutParams）不支持适配器视图*

01-01 23:30:29.858: ERROR/AndroidRuntime(14911): FATAL EXCEPTION: main *01-01 23:30:29.858: ERROR/AndroidRuntime(14911): java.lang.UnsupportedOperationException: addView(View, LayoutParams) is not supported in AdapterView*

我没有一个线索做什么，我看着在谷歌和我没有找到任何东西，我也做了同样的计算器。这是Java和Android的我的第一个aplication所以我是一个真正的n00b如果答案是有，我不明白，所以我真的很AP preciate如果你能解释一下我应该做些什么来解决这个问题错误和原因。

I don't have a clue what to do, I've looked up in Google and I didn't find anything and I did the same at stackoverflow. This is my first aplication in Java and for Android so I'm a real n00b and if the answer was there, I didn't understand it so I would really appreciate if you could explain what I should do to fix this error and why.

感谢一切在前进。

推荐答案

在创建一个 ArrayAdapter 像你这样的，一个ArrayAdapter需要一个布局资源仅包含一个TextView。 试着改变你的ArrayAdapter与创造：

When creating an ArrayAdapter like yours, the ArrayAdapter needs a layout resource containing just a TextView. Try changing your ArrayAdapter creation with:

setListAdapter（新ArrayAdapter＆LT;字符串＆GT;（这一点，android.R.layout.simple_list_item_1，this.directoryEntries））;

和看看是否可行。
