Android-尝试停止处理程序

问题描述

在验证电子邮件handler.removeCallbacks(runnable);后尝试停止处理程序运行，但是我无法通过代码停止它，想知道将停止处理程序代码放在哪里

public class unverifiedEmail extends AppCompatActivity {
FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
private Button btnResend;
public static final String TAG = "TAG";
private Handler handler = new Handler();
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_unverrified_email);

    btnResend = findViewById(R.id.btnResend);

    btnResend.setonClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
                user.sendEmailVerification().addOnSuccessListener(new OnSuccessListener<Void>() {
                @Override
                public void onSuccess(Void aVoid) {
                    Toasty.info(unverifiedEmail.this,"New Verification Email has Sent",Toast.LENGTH_SHORT).show();
                }
        }).addOnFailureListener(new OnFailureListener() {
                @Override
                public void onFailure(@NonNull Exception e) {
                    Log.d(TAG,"onFailure: Error On Sending Verification Email"+e.getMessage());
                }
            });
         };
    });
    handler.post(runnable);
}

private Runnable runnable = new Runnable() {
    @Override
    public void run() {
        // Insert custom code here
        user.reload();
        if (!user.isEmailVerified()){

        }else {
            handler.removeCallbacks(runnable);
            Toasty.info(unverifiedEmail.this,"Your Account has Verified",Toast.LENGTH_SHORT).show();
            startActivity(new Intent(getApplicationContext(),dashboard.class));
            finish();
        }

        // Repeat every 5 seconds
        handler.postDelayed(runnable,5000);
    }

};
