如何在输出文件和显示列表视图中多次录制音频

Question

我的代码只能录制一个音频并显示列表视图，但我想在outfile和显示列表视图中录制更多音频。

 OUTPUT_FILE=Environment.getExternalStorageDirectory()+"/" + name + ".3gpp";
    Log.d("Files", "Path: " + OUTPUT_FILE);
    File f = new File(OUTPUT_FILE);        
     myList = new ArrayList<String>();
     myList.add(f.getName());
   ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
            android.R.layout.simple_list_item_1, android.R.id.text1, myList);
    listView.setAdapter(adapter);
    listView.setOnItemClickListener(new OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position,
                long id) {
            try
            {
                playRecording();
            }
            catch(Exception e)
            {
                e.printStackTrace();
            }
        }
    });

Answer 1

最后我发现了问题，正确的代码如下所示：

myList = new ArrayList<String>();
        file = new File( "/sdcard/"+name+"/");
        file.mkdirs();
        File list[] = file.listFiles();
        for( int i=0; i< list.length; i++)
        {
           myList.add( list[i].getName() );
        }
        ListView listView = (ListView) findViewById(R.id.mylist);
           ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
                    android.R.layout.simple_list_item_1, android.R.id.text1, myList);
            listView.setAdapter(adapter);
