Question

我必须在我的应用程序中添加忘记密码。我必须先在对话框中发送电子邮件，该对话框将用于检查数据库中的相应密码并在通知中显示密码。

public class OwnerLoginActivity extends AppCompatActivity {
    EditText txtlogin;
    EditText txtpassword;
    TextView lblforgotpassword;
    Button btnlogin;
    Button btnregister;
    MyDatabase database;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_owner_login);
        txtlogin=(EditText)findViewById(R.id.txtlogin);
        txtpassword=(EditText)findViewById(R.id.txtpassword);
        btnlogin=(Button)findViewById(R.id.btnlogin);
        btnregister=(Button)findViewById(R.id.btnregister);
        lblforgotpassword=(TextView)findViewById(R.id.lblforgotpassword);
        database=new MyDatabase(OwnerLoginActivity.this);

        lblforgotpassword.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
               Toast.makeText(OwnerLoginActivity.this, "forgot password", Toast.LENGTH_SHORT).show();
                forgotPassword();
            }
        });


        btnlogin.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                checkLogin();
            }
        });

        btnregister.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Toast.makeText(OwnerLoginActivity.this, "Registered Button Clicked", Toast.LENGTH_SHORT).show();
                Intent obj=new Intent(OwnerLoginActivity.this,OwnerRegistrationActivity.class);
                startActivity(obj);
                finish();
            }
        });}


    public void checkLogin() {
        AndroidNetworking.post("http://192.168.43.38/internship_project/android_web_services/login.php")
            .addBodyParameter("email",txtlogin.getText().toString())
            .addBodyParameter("password",txtpassword.getText().toString()).setTag("Login").setPriority(Priority.MEDIUM)
            .build()
            .getAsJSONObject(new JSONObjectRequestListener() {
                @Override
                public void onResponse(JSONObject response) {

                    System.out.println(response.toString());
                    try {
                        if(response.getString("success").equals("1")){

                            Toast.makeText(OwnerLoginActivity.this, response.getString("message"), Toast.LENGTH_SHORT).show();
                            Intent intent=new Intent(OwnerLoginActivity.this, ActDashboard.class);
                            startActivity(intent);
                        }
                        else
                            Toast.makeText(OwnerLoginActivity.this, response.getString("message"), Toast.LENGTH_SHORT).show();


                    } catch (JSONException e) {
                        e.printStackTrace();
                    }

                }

                @Override
                public void onError(ANError anError) {
                    System.out.println(anError.toString());
                    Toast.makeText(OwnerLoginActivity.this, "Server time out please try again later", Toast.LENGTH_SHORT).show();
                }

            });
    }

    public void forgotPassword() {
        AlertDialog.Builder builder=new AlertDialog.Builder(this);
        LayoutInflater inflater=this.getLayoutInflater();
        final View dialogview=inflater.inflate(R.layout.custom_dialog,null);
        builder.setView(dialogview);
        final EditText edt=(EditText)dialogview.findViewById(R.id.email);
        builder.setTitle("Forgot password?");
        builder.setMessage("Enter your email id");
        builder.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
            }
        });
        builder.setNegativeButton("Cancel", new     DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                dialog.cancel();
            }
        });
        AlertDialog b=builder.create();
        b.show();

    }
}

我已经在onClick上添加了警告框，但问题是我不知道如何从数据库中获取密码。我是否必须在forgotPassword方法中添加Android网络？并为其创建单独的PHP文件？

编辑：我在我的程序中做了android网络，并在其中调用了通知方法（我为警报框和通知制作了两个单独的方法，并为Android网络提供了不同的方法）。我在alert box方法中调用了网络方法，并在网络中调用了密码方法。它显示了警告框，但密码通知不起作用。它给出了JSON对象错误
