智能管家---11. 用户重置密码功能实现（忘记密码或重置）

接下来实现重置密码，图解：

所以分两步走，有原始密码或没有原始密码。

• 重置密码界面
  
  xml文件：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"

    <Button
        android:id="@+id/btn_forget_password"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@drawable/button_bg"
        android:text="确认"
        android:textColor="@android:color/white"/>


</LinearLayout>

• 具体实现，重置密码也是获取用户输入的内容，或直接修改密码，或通过邮箱重置
• 直接修改密码
  

• 邮箱重置
  

• ForgetPasswordActivity源代码

public class ForgetPasswordActivity extends BaseActivity implements View.OnClickListener {

    private EditText et_now,et_new,et_new2;
    private EditText et_email;
    private Button btn_update;
    private Button btn_forget;

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_forget);

        initView();
    }

    private void initView() {
        et_now=(EditText)findViewById(R.id.et_now);
        et_new=(EditText)findViewById(R.id.et_new);
        et_new2=(EditText)findViewById(R.id.et_new_password);
        et_email=(EditText)findViewById(R.id.et_email);
        btn_update=(Button)findViewById(R.id.btn_update_password);
        btn_forget=(Button)findViewById(R.id.btn_forget_password);

        btn_update.setOnClickListener(this);
        btn_forget.setOnClickListener(this);

    }

    @Override
    public void onClick(View v) {
        switch (v.getId()){
            case R.id.btn_update_password:
