java - java.lang.IllegalStateException：在父级或祖先中找不到方法 onClickForgot(View)

Question

我在忘记密码活动中遇到错误，在单击忘记密码时，应用程序正在停止并出现错误

进程：com.example.beasport.sport，PID：5878 java.lang.IllegalStateException：在视图类 android.support.v7.widget 上定义的 android:onClick 属性的父或祖先上下文中找不到方法 onClickForgot(View)。 AppCompatTextView 在 android.support.v7.app.AppCompatViewInflater$DeclaredOnClickListener.resolveMethod(AppCompatViewInflater.java:423) 在 android.support.v7.app.AppCompatViewInflater$DeclaredOnClickListener.onClick(AppCompatViewInflater.java:380) 在 android.support.v7.app. .view.View.performClick(View.java:5637) 在 android.os.Handler.handleCallback(Handler.java:751) 在 android.view.View$PerformClick.run(View.java:22429) 在 android.os。 Handler.dispatchMessage(Handler.java:95) 在 android.os.Looper.loop(Looper.java:154) 在 com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:第886章）

我忘记密码的活动和相应xml的文件是：

                return;
            }

            progressBar.setVisibility(View.VISIBLE);

            auth.sendPasswordResetEmail(email)

                    .addOnCompleteListener(new OnCompleteListener<Void>() {

                            } else {

                            }

                            progressBar.setVisibility(View.GONE);
                        }
                    });
        }
    });
}
