问如何选择和获取安卓手机中的文件路径(如.txt或.apk文件)

EN

Intent intent = new Intent();
intent.setType("*/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(intent, 1); 

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    // TODO Auto-generated method stub
    try {
        Uri uri = data.getData();
        ContentResolver cr = getActivity().getContentResolver();  

        Cursor cursor = cr.query(uri, null, null, null, null);  
        cursor.moveToFirst();

        Log.i("PATH", "File path = " + cursor.getString(1));
        Filepath = cursor.getString(1);
        filepath.setText(Filepath);
    } catch (Exception e) {
        // TODO: handle exception
    }
    super.onActivityResult(requestCode, resultCode, data);
}
