用户登录流程中，记住密码和自动登录逻辑。

就是普通登录流程中记住密码和自动登录的功能，因为感觉checkbox  控件太小点击有点困难。所以在外层的父控件上添加了点击监听。直接上代码LoginActivity：

/**
* 登录页面
*
* @author hjl
*         created at 2016/12/15 13:51
*/
public class LoginActivity extends AppCompatActivity implements View.OnClickListener {
private SharedPreferences sp;
private SharedPreferences.Editor editor;

private EditText edittext_user;
private EditText edittext_psd;
private Button login;
private CheckBox check_remember;
private CheckBox check_automatic;
private LinearLayout automatic_login;
private LinearLayout remember_psd;
private String userNameValue, passwordValue;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
initView();
}

private void initView() {
sp = this.getSharedPreferences("person", MODE_PRIVATE);// 初始化 SharedPreferences 储存
editor = sp.edit();//将SharedPreferences 储存 可编辑化

edittext_user = ((EditText) findViewById(R.id.EditText_user));//用户名输入框
edittext_psd = ((EditText) findViewById(R.id.EditText_psd));//密码输入框
login = ((Button) findViewById(R.id.button_login));//登录
check_remember = ((CheckBox) findViewById(R.id.checkbox_one));//记住密码
check_automatic = ((CheckBox) findViewById(R.id.checkbox_two));//重新登录
automatic_login = ((LinearLayout) findViewById(R.id.layout_automatic_login));
remember_psd = ((LinearLayout) findViewById(R.id.layout_remember_psd));

//判断记住密码多选框的状态
if (sp.getBoolean("ISCHECK", false)) {
//设置默认是记录密码状态
check_remember.setChecked(true);
edittext_user.setText(sp.getString("USER_NAME", ""));
edittext_psd.setText(sp.getString("PASSWORD", ""));
//判断自动登陆多选框状态
if (sp.getBoolean("AUTO_I
4000
SCHECK", false)) {
//设置默认是自动登录状态
check_automatic.setChecked(true);
//跳转界面
Intent intent = new Intent(LoginActivity.this, MainActivity.class);
LoginActivity.this.startActivity(intent);
finish();
}
}

//添加点击监听的接口回调
login.setOnClickListener(this);
automatic_login.setOnClickListener(this);
remember_psd.setOnClickListener(this);
}
@Override
public void onClick(View v) {

userNameValue = edittext_user.getText().toString();
passwordValue = edittext_psd.getText().toString();
//请求借口进行登录 这里直接默认 账号hjl  密码123：
switch (v.getId()) {
case R.id.button_login:
if (userNameValue.endsWith("hjl") && passwordValue.endsWith("123")) {
ToastUtils.toastShort("login");
if (check_remember.isChecked()) {
//记住用户名、密码、
editor.putString("USER_NAME", userNameValue);
editor.putString("PASSWORD", passwordValue);
editor.commit();
}
//跳转界面
Intent intent = new Intent(LoginActivity.this, MainActivity.class);
startActivity(intent);
finish();
} else {
ToastUtils.toastShort("用户名和密码错误");
}
break;
case R.id.layout_automatic_login:
if (check_automatic.isChecked()) {
check_automatic.setChecked(false);
ToastUtils.toastShort("自动登录未选中");
sp.edit().putBoolean("AUTO_ISCHECK", false).commit();
} else {
check_automatic.setChecked(true);
ToastUtils.toastShort("自动登录选中");
sp.edit().putBoolean("AUTO_ISCHECK", true).commit();
}
break;
case R.id.layout_remember_psd:
if (check_remember.isChecked()) {
check_remember.setChecked(false);
ToastUtils.toastShort("记住密码未选中");
sp.edit().putBoolean("ISCHECK", false).commit();
} else {
check_remember.setChecked(true);
ToastUtils.toastShort("记住密码选中");
sp.edit().putBoolean("ISCHECK", true).commit();
}
break;
}
}
}
