由於個人無法管理大量的用戶名和密碼，而又不敢隨便下載一些現成的app來管理這樣的敏感數據，抱着既爲了學習又爲了使用的態度開發了這個簡易的密碼倉庫安卓應用。
主要功能如下：
1、訪問密碼倉庫應用的手勢鎖創建、手勢鎖驗證、手勢鎖重置
2、賬號與密碼的添加、修改、刪除、查看與搜索
3、密碼（包括手勢鎖密碼與添加的賬號密碼）的加密解密
截圖如下：
列表中上面是賬號信息下面是賬號名，點擊條目後會toast彈出密碼的明文來，當然要進入這個界面得先通過手勢鎖驗證。
大體應用的邏輯如下：
1、啓動後判斷用戶是否已設置手勢鎖，沒有則跳轉至設置界面，若已設置則跳轉至手勢鎖驗證界面;
主要代碼：

}4、賬號列表頁——這個頁面主要是從本地數據庫讀入賬號信息，並以Listview呈現出來，當點擊listviewitem後，會查找對應的賬號密碼密文，將其解密後toast出明文給用戶。此頁面上也可以添加新賬戶信息，搜索賬號信息，長按item編輯、刪除條目。這裏數據庫操作我使用了一個orm框架GreenDAO，感興趣的同學可以搜索一下這類框架的用法，搜索部分我使用了安卓提供的搜索接口，朋友們可以參考安卓官方文檔中UserInterface-Search下的內容。源碼如下：
public class PwdListActivity extends Activity implements OnClickListener {
private ListView listv;
private BaseAdapter adapter;
private List<account> accountlist;
private PopupWindow pop;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_pwdlist);
listv = (ListView) findViewById(R.id.listview);
listv.setOnItemClickListener(new MonItemClickListener());
listv.setOnItemLongClickListener(new MLongClickListener());
}
@Override
protected void onResume() {
accountDao aDao = DAOUtils.getAccountDao(this);
accountlist = aDao.queryBuilder().list();
adapter = new PwdAdapter();
listv.setAdapter(adapter);
super.onResume();
}
private class PwdAdapter extends BaseAdapter {
@Override
public int getCount() {
return accountlist.size();
}
@Override

return accountlist.get(position);
}
@Override
public long getItemId(int position) {
return 0;
}
@Override
public View getView(int position, View cv, ViewGroup group) {
ViewHolder holder = null;
account acc = accountlist.get(position);
if (cv != null) {
holder = (ViewHolder) cv.getTag();
} else {

R.layout.listitem, null);
holder = new ViewHolder();
holder.img = (ImageView) cv.findViewById(R.id.img);

cv.setTag(holder);
}
try {
Log.d("pwdlist", acc.getImguri() + " " + acc.getProvider()
+ " ");
if(!TextUtils.isEmpty(acc.getImguri()))
ImageLoader.getInstance().displayImage(acc.getImguri(),
holder.img);
else
holder.img.setImageResource(R.drawable.ic_launcher);
holder.tv_name.setText(acc.getProvider());
holder.tv_account.setText(acc.getUname());
} catch (Exception e) {
}
return cv;
}

}
private class MonItemClickListener implements OnItemClickListener {

account acc = (account) listv.getAdapter().getItem(position);
String shadow = acc.getShadow();
Log.d("shadow pwd", shadow);
ToastUtils.show(PwdListActivity.this, AES.dec(shadow));
}
}
@Override
public void onClick(View v) {
switch (v.getId()) {

pop.dismiss();

private class MLongClickListener implements OnItemLongClickListener {

LayoutParams.WRAP_CONTENT);
pop.setFocusable(true);
pop.setBackgroundDrawable(getResources().getDrawable(
R.color.gray_background));
pop.setOutsideTouchable(true);
pop.showAsDropDown(v);
return false;
}
}
private class MPositiveOnClickListener implements DialogInterface.OnClickListener{
account acc;
public MPositiveOnClickListener(account acc) {
this.acc=acc;
}
@Override
public void onClick(DialogInterface arg0, int arg1) {
accountDao accDao=DAOUtils.getAccountDao(PwdListActivity.this);
accDao.delete(acc);
accountlist = DAOUtils.getAccountDao(PwdListActivity.this).queryBuilder().list();
adapter = new PwdAdapter();
listv.setAdapter(adapter);
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main, menu);
SearchManager manager=(SearchManager) getSystemService(Context.SEARCH_SERVICE);
SearchView searchview=(SearchView)menu.findItem(R.id.searchview).getActionView();//XXX
searchview.setSearchableInfo(manager.getSearchableInfo(new ComponentName("com.lttclaw.pwdrepository", "com.lttclaw.pwdrepository.SearchActivity")));
searchview.setOnQueryTextListener(new OnQueryTextListener() {
@Override
public boolean onQueryTextSubmit(String arg0) {
return false;
}
@Override
public boolean onQueryTextChange(String arg0) {
return false;
}
});
searchview.setSubmitButtonEnabled(true);
return true;
}
}這些就是應用中最核心的部分了，剩下的像加密類、控件類、常量類大家可以在源碼裏找到，希望大家能在此找到對自己有用的東西~
