Android OnClickListener Not Being Called

Question

I have a FloatingActionButton in my MainActivity that, when clicked, takes me to a new Activity called newPlant . I have this declared in my android manifest as such:

<activity
    android:name="newPlant"
    android:label="@string/app_name">
</activity>

The Label is the same as MainActivity because I didn't really know what the label was for. in the newPlant activity I have another FloatingActionButton as well as a ImageButton that are supposed to be clickable. When I first began having trouble I found and went through this post , which helped. Now the problem is the none of the code inside the onClickListeners is being executed (I have Log.D methods in each listener that are not being called). Here is my newPlant.Java File as well as the accompanying Layout File.

    public class newPlant extends AppCompatActivity implements OnClickListener {

    private ImageButton plantCam;
    private FloatingActionButton savePlant;
    private EditText newPlantName;
    private EditText newPlantWF;

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.newplant);
        plantCam = (ImageButton)findViewById(R.id.newPlantImage);
        savePlant = (FloatingActionButton)findViewById(R.id.savePlant);
        newPlantName = findViewById(R.id.newPlantName);
        newPlantWF = findViewById(R.id.newPlantWF);
        setContentView(R.layout.newplant);
        plantCam.setOnClickListener(this);
        savePlant.setOnClickListener(this);
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        Bitmap bitmap = (Bitmap)data.getExtras().get("data");
        plantCam.setImageBitmap(bitmap);
    }

    public void onClick(View v){
        switch(v.getId()){
            case R.id.newPlantImage:{
                Log.d("plantCam", "clicked");
                Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
                startActivityForResult(intent,0);
                break;
            }case R.id.savePlant:{
                Log.d("SavePlant", "clicked");
                MyApplication.myPlantList.add(new Plant(newPlantName.getText().toString(), plantCam.getDrawable(), newPlantWF.getText().toString()));
                MyApplication.savePlants();
                finish();
                Log.d("SavePlant", "finished saving plant" + MyApplication.myPlantList.toString());
                break;
            }
        }
    }
}

Answer 1

For some reason I called setContentView() twice. This was the issue. Thanks to those who pointed this out.
