本文简单实现了用ListView显示SDCard文件列表，目录的回退等功能暂不讨论
获取文件列表，files即为所选择目录下的所有文件列表
filePath = Environment.getExternalStorageDirectory().getAbsolutePath() + “/ADASiteMaps/SigRecord”;
File file=new File(filePath);
File[] files = file.listFiles();
构造Adapter，
for(File mCurrentFile:files){
mFileName.add(mCurrentFile.getName());
}
ArrayAdapter<String> mAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_expandable_list_item_1,mFileName);
显示 ListView
fileListView.setAdapter(mAdapter);
ListView点击事件的处理：
fileListView = (ListView) findViewById(R.id.filelistView);
fileListView.setOnItemClickListener(fileListViewItemClickListener);
private AdapterView.OnItemClickListener fileListViewItemClickListener =
new AdapterView.OnItemClickListener(){
@Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
// TODO Auto-generated method stub
//test…………………….
// TextView textview = (TextView)findViewById(R.id.textViewfile);
// textview.append(mFileName.get(position).toString());
}
};
结果如下图：
