Android sharedPreferences实现记住密码功能

实现记住密码功能，供大家参考，具体内容如下

编写界面交互代码：

package com.example.bz0209.login;

import android.content.dialoginterface;
import android.content.intent;
import android.content.sharedpreferences;
import android.support.v7.app.appcompatactivity;
import android.os.bundle;
import android.view.view;
import android.widget.button;
import android.widget.checkbox;
import android.widget.edittext;
import android.widget.toast;

public class mainactivity extends appcompatactivity {
  private edittext username;
  private edittext password;
  private checkbox ck;
  private sharedpreferences sharedpreferences;
  @override
  protected void oncreate(bundle savedinstancestate) {
    super.oncreate(savedinstancestate);
    setcontentview(r.layout.activity_main);
    initview();
    sharedpreferences=getsharedpreferences("remeberword",mode_private);
    boolean isremeber=sharedpreferences.getboolean("remeberword",false);
    if(isremeber) {
      string name=sharedpreferences.getstring("name","");
      string pass=sharedpreferences.getstring("pass","");
      username.settext(name);
      password.settext(pass);
      ck.setchecked(true);
    }
  }
  private void initview(){
    username=(edittext)findviewbyid(r.id.username);
    password=(edittext)findviewbyid(r.id.password);
    ck= (checkbox) findviewbyid(r.id.ck);
  }
  private void login(view view){//在layout中设置onclick事件
    string name=username.gettext().tostring();
    string pass=password.gettext().tostring();
    if("admin".equals(name)&&"123".equals(pass)){
     sharedpreferences.editor editor=sharedpreferences.edit();
      if(ck.ischecked()){
        editor.putboolean("remeberword",true);
        editor.putstring("name",name);
        editor.putstring("pass",pass);
      }else{
        editor.clear();
      }
      editor.commit();
    }
  }
}
