Question

我是一个Android应用程序，它从vcf file获取联系人并保存到Android设备，代码是：

String tmptype = mime.getMimeTypeFromExtension("vcf");
final File file = new File(Environment.getExternalStorageDirectory().toString() + "/contacts.vcf");
Intent i = new Intent();
i.setDataAndType(Uri.fromFile(file), "text/x-vcard");
startActivity(i);

将所有联系人保存到设备中但问题是它希望用户界面选择保存的位置。但我想直接保存到PhoneMemory或Phonebook。我不想在插入Contacts时有任何其他选项。我在网上搜索找不到任何答案请帮助找出这个

public class VCardActivity extends Activity {
Cursor cursor;
ArrayList<String> vCard;
String vfile;
static Context mContext;

/** Called when the activity is first created. */
@Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        mContext = VCardActivity.this;
        getVCF();
    }

    public static void getVCF() {
        final String vfile = "Contacts.vcf";
        Cursor phones = mContext.getContentResolver().query(
        ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, null);
        phones.moveToFirst();
        for (int i = 0; i < phones.getCount(); i++) {
            String lookupKey = phones.getString(phones.getColumnIndex(ContactsContract.Contacts.LOOKUP_KEY));
            Uri uri = Uri.withAppendedPath(ContactsContract.Contacts.CONTENT_VCARD_URI, lookupKey);
            AssetFileDescriptor fd;
            try {
                fd = mContext.getContentResolver().openAssetFileDescriptor(uri, "r");
                FileInputStream fis = fd.createInputStream();
                byte[] buf = new byte[(int) fd.getDeclaredLength()];
                fis.read(buf);
                String VCard = new String(buf);
                String path = Environment.getExternalStorageDirectory().toString() + File.separator + vfile;
                FileOutputStream mFileOutputStream = new FileOutputStream(path, true);
                mFileOutputStream.write(VCard.toString().getBytes());
                phones.moveToNext();
                Log.d("Vcard", VCard);
            } catch (Exception e1) {
                // TODO Auto-generated catch block
                e1.printStackTrace();
            }
        }
    }
}

Add on Manifest：

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
