Below is the simple method to send the reset password link on user email address with progress dialog (sometime firebase took time to complete reset password request because of slow internet connection on client side, so progress dialog will be helpful)

下面是使用进度对话框在用户电子邮件地址上发送重置密码链接的简单方法（有时firebase需要时间来完成重置密码请求，因为客户端连接速度较慢，因此进度对话框将有所帮助）

public void resetUserPassword(String email){
        FirebaseAuth mAuth = FirebaseAuth.getInstance();
        final ProgressDialog progressDialog = new ProgressDialog(ForgotPasswordActivity.this);
        progressDialog.setMessage("verifying..");
        progressDialog.show();

        mAuth.sendPasswordResetEmail(email)
                .addOnCompleteListener(new OnCompleteListener() {
                    @Override
                    public void onComplete(@NonNull Task task) {
                        if(task.isSuccessful()){
                            progressDialog.dismiss();
                            Toast.makeText(getApplicationContext(), "Reset password instructions has sent to your email",
                                    Toast.LENGTH_SHORT).show();
                        }else{
                            progressDialog.dismiss();
                            Toast.makeText(getApplicationContext(),
                                    "Email don't exist", Toast.LENGTH_SHORT).show();
                        }
                    }
                }).addOnFailureListener(new OnFailureListener() {
            @Override
            public void onFailure(@NonNull Exception e) {
                progressDialog.dismiss();
                Toast.makeText(getApplicationContext(), e.toString(), Toast.LENGTH_SHORT).show();
            }
        });
    }

If Kotlin is your language of choice you can use this:

如果Kotlin是您的首选语言，您可以使用：

val fAuth = FirebaseAuth.getInstance()
fAuth.sendPasswordResetEmail(email).addOnCompleteListener({ listener ->
        if (listener.isSuccessful) {
            // Do something when successful
        } else {
            // Do something when not successful
        }
})
