Как обрабатывать виджетов на двух макетах за один вид деятельности

Question

У меня есть следующий код, в котором я хочу сделать, когда щелкнуть текстовое изображение sigup, тогда он должен отобразить второй макет, который является линейным, в верхней части относительной компоновки. Он работает по этому вопросу. Затем я хочу показать еще один макет с информацией о регистрации, когда кнопка «Разрешить» нажата на втором экране, но этого не происходит. файл xml прилагается.

package care.e_eyepewsversion2; 

public class MainActivity extends AppCompatActivity { 


    @Override

Answer 1

OnCreate метод вызывается один раз время.

Так что, когда он выполняется во время создания действия, он находит if(visibility1==View.VISIBLE), что неверно (потому что adminacesslayout имеет visibility GONE).

Таким образом, вы не надуваете adminlogin, и вы не настроите на нем Button.OnClickListener.

Что вам нужно это:

public class MainActivity extends AppCompatActivity { 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.test); 
     Button login = (Button) findViewById(R.id.loginbutton); 
     TextView signup = (TextView) findViewById(R.id.signup); 

     EditText email1 = (EditText) findViewById(R.id.Email); 
     EditText password1 = (EditText) findViewById(R.id.Password); 


     if (signup != null) { 
      signup.setOnClickListener(new TextView.OnClickListener() { 
              public void onClick(View V) { 
               showAdminacesslayout(); 

              } 
             } 
      ); 
     } 

     LinearLayout adminacesslayout = (LinearLayout) findViewById(R.id.adminaccesslayout); 
     int visibility1 = adminacesslayout.getVisibility(); //  if(visibility1==View.VISIBLE) //  { // //   Button 
adminlogin = (Button) findViewById(R.id.adminpassbutton); // //  
if (adminlogin != null) { //    
adminlogin.setOnClickListener(new Button.OnClickListener(){ //  
public void onClick(View V){ //          
EditText adminpass= (EditText) findViewById(R.id.admiinpass); //  
String adminpasswordtyped= adminpass.getText().toString(); // //  
//  if("1234".equals(adminpasswordtyped)) //     
//  { LinearLayout adminacesslayout= (LinearLayout) 
findViewById(R.id.adminaccesslayout) ; //       
//   adminacesslayout.setVisibility(View.GONE); //   
//  } //              
RelativeLayout signuplayout= (RelativeLayout) 
findViewById(R.id.signup_layout); //         
int visibility2=signuplayout.getVisibility(); //      
if(visibility2==View.GONE) //          
{ //               
LinearLayout adminacesslayout= (LinearLayout) 
findViewById(R.id.adminaccesslayout) ; //       
adminacesslayout.setVisibility(View.GONE); //      
signuplayout.setVisibility(View.VISIBLE); //       
} // // //             } // // 
} // //    ); //   } //  } 


     login.setOnClickListener(new Button.OnClickListener() { 
            public void onClick(View V) { 
             checkdetails(); 
            } 

           } 
     ); 
    } 

    private void showAdminacesslayout() { 

     Button login = (Button) findViewById(R.id.loginbutton); 
     login.setVisibility(View.INVISIBLE); 
     LinearLayout adminacesslayout = (LinearLayout) findViewById(R.id.adminaccesslayout); 
     int visibility = adminacesslayout.getVisibility(); 

     if (visibility == View.GONE) { 
      adminacesslayout.setVisibility(View.VISIBLE); 
     } 

     Button adminlogin = (Button) findViewById(R.id.adminpassbutton); 

     if (adminlogin != null) { 
      adminlogin.setOnClickListener(new Button.OnClickListener() { 
               public void onClick(View V) { 
                EditText adminpass = (EditText) findViewById(R.id.admiinpass); 
                String adminpasswordtyped = adminpass.getText().toString(); 

                //  if("1234".equals(adminpasswordtyped)) 
                //  { LinearLayout adminacesslayout= (LinearLayout) 
findViewById(R.id.adminaccesslayout) ; 
                //   adminacesslayout.setVisibility(View.GONE); 
                //  } 
                RelativeLayout signuplayout = (RelativeLayout) findViewById(R.id.signup_layout); 
                int visibility2 = signuplayout.getVisibility(); 
                if (visibility2 == View.GONE) { 
                 LinearLayout adminacesslayout = (LinearLayout) 
findViewById(R.id.adminaccesslayout); 
                 adminacesslayout.setVisibility(View.GONE); 
                 signuplayout.setVisibility(View.VISIBLE); 
                } 


               } 

              } 

      ); 
     } 
    } 

    public void checkdetails() { 
     EditText email = (EditText) findViewById(R.id.Email); 
     EditText password = (EditText) findViewById(R.id.Password); 
     String emailtyped = email.getText().toString(); 
     String passwordtyped = password.getText().toString(); 
     String filename = "my file"; 


     //Writing to file section 
     String string = "Hello world!"; 
     FileOutputStream outputStream; 

     try { 
      outputStream = openFileOutput(filename, Context.MODE_PRIVATE); 
      outputStream.write(emailtyped.getBytes()); 
      outputStream.write("\r\n".getBytes()); 
      outputStream.write(passwordtyped.getBytes()); 
      outputStream.close(); 
      Context context = getApplicationContext(); 
      CharSequence text = "Login history Saved"; 
      int duration = Toast.LENGTH_SHORT; 

      Toast toast = Toast.makeText(context, text, duration); 
      toast.show(); 
     } catch (Exception e) { 
      e.printStackTrace(); 
     } 


     //Reading from file section Text 

     if ("ciao".equals(emailtyped)) { //  if (getString(R.string.firstemailtyped).equals(emailtyped)) { 
      if ("1234".equals(passwordtyped)) { 
       Button loogin = (Button) findViewById(R.id.loginbutton); 
       TextView dummydata = (TextView) findViewById(R.id.dummydata); 


       // After that, you can call read method to read one character at a time from the file and then you can print it. Its 
syntax is given below − 

       try { 
        InputStream inputStream = openFileInput("my file"); 

        if (inputStream != null) { 
         InputStreamReader streamReader = new InputStreamReader(inputStream); 
         BufferedReader bufferedReader = new BufferedReader(streamReader); 

         String l; 
         String k = ""; 

         while ((l = bufferedReader.readLine()) != null) { 
          // do what you want with the line 
          k = (k + l); 
          dummydata.setText(k); 
         } 

        } 

        inputStream.close(); //close the file 
       } catch (IOException e) { 
        e.printStackTrace(); 
       } 


      } 
     } 
    } 


} 

Или более просто вы можете удалить эти строки, сохраняя код в скобках:

int visibility1 = adminacesslayout.getVisibility(); 
if(visibility1==View.VISIBLE) 
{ 

... 

}
