Why doesn't the intent of the button work

Question

In my Code I have an Intent to an other Activity but when I use my Phone to test it nothing appears. The program doesn't crashes or something like that. It simply does nothing. I have another Intent and this works perfectly. I don't know what the problem is.

I am using the onClick feature on the xml file

On the Main Activity:

public class MainActivity extends AppCompatActivity {
    private Object TextView;
    int eggcounter;
    Button b1;

    android.widget.TextView textClicks;
    private Object SafeBrowsingResponse;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        final Button b1 = findViewById(R.id.b1);

        eggcounter = 100;
        final ImageButton ImgButton = findViewById(R.id.eggBtn);

        ImgButton.setOnClickListener(
                new View.OnClickListener() {
                    public void onClick(View view) {
                        eggcounter = eggcounter - 1;
                        updateEgg();
                        if (eggcounter < 80) {
                            ImgButton.setImageResource(R.drawable.egg_2);
                            if (eggcounter < 60){
                                ImgButton.setImageResource(R.drawable.egg_3);
                                if (eggcounter < 40) {
                                    ImgButton.setImageResource(R.drawable.egg_4);
                                    if (eggcounter < 15) {                                        ImgButton.setImageResource(R.drawable.egg_5);
                                        if (eggcounter <= 0) {
                                            b1.setVisibility(View.VISIBLE);

                                            ImgButton.setImageResource(R.drawable.egg_ende);
                                            b1.setOnClickListener(
                                                    new View.OnClickListener() {

                                                        public void onClick(View view) {

                                                        }
                                                    }
                                            );

                                        }
                                    }
                                }
                            }
                        }
                    }
                }
        );
    }

    public void updateEgg() {
        textClicks = (TextView) findViewById(R.id.textScore);
        textClicks.setText(eggcounter + " ");
    }

    public void backstartseite(View view) {
        Intent back = new Intent(this, Startseite.class);
        startActivity(back);
    }

    public void ende (View view) {
        Intent e = new Intent(this, Ende.class);
        startActivity(e);
    }
}

Answer 1

You are never calling backStartSeite or ende therefore no Intent fires.

Also don't set the onClickListener of b1 inside another onClickListener (your listener for b1 will only be able to handle click events once the other button has been clicked already - this would confuse users).

If you want your Intent to work, call either startSeite or ende in the outer onClickListener.
