chromium 原生实现

3个关键类

SavePasswordsPreferences extends Fragment //password 界面

//负责和native层进行交互
public final class PasswordUIView {
    //内部类， 代表一项password item
    public static final class SavedPasswordEntry {
        private final String mUrl;
        private final String mName;
    }

    public interface PasswordListObserver {
        /**
         * Called when passwords list is updated.
         * @param count Number of entries in the password list.
         */
        void passwordListAvailable(int count);

        /**
         * Called when password exceptions list is updated.
         * @param count Number of entries in the password exception list.
         */
        void passwordExceptionListAvailable(int count);
    }

    private ObserverList<PasswordListObserver> mObservers =
            new ObserverList<PasswordListObserver>();

//底层保存密码完后， jni调用java层的passwordListAvailable(), 进而通知所有的observer.
    @CalledByNative
    private void passwordListAvailable(int count) {
        JLog.i(count);
        for (PasswordListObserver observer : mObservers) {
            observer.passwordListAvailable(count);
        }
    }
}

PasswordEntryEditor.java  //Password entry editor that allows to view and delete passwords stored in Chrome.

项目自定义的实现

2个关键类

PasswordSettingActivity //保存密码的界面
PasswordAdapter //密码列表使用的adapter

保存密码的文件

chrome保存的位置:
/data/data/com.android.chrome/app_chrome/Default/Login Data  
自己浏览器保存的位置:
/data/data/com.qihoo.browser/app_chrome/Default/Login Data

注意一点: 明文保存， 有一定的安全隐患.
