  79.         });
  80.     }
  82.     // 省略其他部分...
  83. }
  1. public class Login extends AppCompatActivity {
  3.     Button callSignUp, loginBtn;
  4.     ImageView image;
  5.     TextView logoText, sloganText;
  6.     TextInputLayout username, password;

  26.                 Pair[] pairs = new Pair[7];
  27.                 pairs[0] = new Pair<View,String>(image,"logo_image");
  28.                 pairs[1] = new Pair<View,String>(logoText,"logo_text");
  29.                 pairs[2] = new Pair<View,String>(sloganText,"logo_desc");
  30.                 pairs[3] = new Pair<View,String>(username,"uname_tran");
  31.                 pairs[4] = new Pair<View,String>(password,"password_tran");
  32.                 pairs[5] = new Pair<View,String>(loginBtn,"button_tran");

  34.                 ActivityOptions options = ActivityOptions.makeSceneTransitionAnimation(Login.this,pairs);
  35.                 startActivity(intent, options.toBundle());
  36.             }
  37.         });
  38.     }
  39. }

以上是代码的翻译部分，包括SignUp.java和Login.java中的关键部分。至于出现的错误日志，是因为在SignUp.java中的布局文件中使用了com.google.android.material.textfield.TextInputLayout，但在代码中使用findViewById查找对应的组件时，使用了EditText而不是TextInputLayout。需要修改相关代码以正确处理布局中的组件。

As the title said. I want to make a custom authentication with username on Register form. All code was good and there is no error. But when I'm trying to run the app, It's force close when After I click the Registration button from the Login page. So this is the list code in SignUp.java

  1. public class SignUp extends AppCompatActivity {
  2. //Variabel
  3. private EditText regName, regNpm, regUsername, regEmail, regPassword, regCoPassword;
  4. private Button regBtn, regToLoginBtn;

  13. //Line dibawah untuk menghilangkan status bar dari screen
  14. getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
  15. setContentView(R.layout.activity_sign_up);
  16. //Hooks ke semua elemen xml di activity_sign_up.xml

  81. if (TextUtils.isEmpty(fullname)) {

  86. }
  87. }
  88. private boolean validateUsername() {
  89. username = regUsername.getText().toString().trim();
  90. if (TextUtils.isEmpty(username)) {

  105. }
  106. private boolean validateEmail() {
  107. email = regEmail.getText().toString().trim();
  108. if (TextUtils.isEmpty(email)) {

  140. startActivity(intent);
  141. }
  142. }

}

And this is the listing code from Login.java

  1. public class Login extends AppCompatActivity {
  2. //Variabel
  3. Button callSignUp, loginBtn;
  4. ImageView image;
  5. TextView logoText, sloganText;
  6. TextInputLayout username, password;
  7. @Override
  8. protected void onCreate(Bundle savedInstanceState) {
  9. super.onCreate(savedInstanceState);
  10. //Line dibawah untuk menghilangkan status bar dari screen
  11. getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
  12. setContentView(R.layout.activity_login);
  13. //Hooks
  14. callSignUp = findViewById(R.id.signup_screen);
  15. image = findViewById(R.id.logo_image);
  16. logoText = findViewById(R.id.logo_text);
  17. sloganText = findViewById(R.id.slogan_text);
  18. username = findViewById(R.id.username);
  19. password = findViewById(R.id.password);
  20. loginBtn = findViewById(R.id.login_btn);
  21. callSignUp.setOnClickListener(new View.OnClickListener() {
  22. @Override
  23. public void onClick(View v) {
  24. Intent intent = new Intent(Login.this,SignUp.class);
  25. Pair[] pairs = new Pair[7];
  26. pairs [0] = new Pair&lt;View,String&gt;(image,&quot;logo_image&quot;);
  27. pairs [1] = new Pair&lt;View,String&gt;(logoText,&quot;logo_text&quot;);
  28. pairs [2] = new Pair&lt;View,String&gt;(sloganText,&quot;logo_desc&quot;);
  29. pairs [3] = new Pair&lt;View,String&gt;(username,&quot;uname_tran&quot;);
  30. pairs [4] = new Pair&lt;View,String&gt;(password,&quot;password_tran&quot;);
  31. pairs [5] = new Pair&lt;View,String&gt;(loginBtn,&quot;button_tran&quot;);
  32. pairs [6] = new Pair&lt;View,String&gt;(callSignUp,&quot;login_signup_tran&quot;);
  33. ActivityOptions options = ActivityOptions.makeSceneTransitionAnimation(Login.this,pairs);
  34. startActivity(intent, options.toBundle());
  35. }
  36. });
  37. }

}

And then there's logcat

答案1

得分: 1

它报告 ClassCastException，因为您将 TextInputLayout 误当作 EditText 处理。为包装的 editText 设置单独的 id，并在该视图上调用 getText()，而不是调用 TextInputLayout 上的方法。

英文:

it says ClassCastException because you treat TextInputLayout as EditText. Set a separate id for for the wrapped editText and call getText() on that view instead.
