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(); } }}
