活动ActivityMain已泄露窗口com.android.internal.policy.impl.PhoneWindow $ DecorView

Question

每次显示自定义对话框时都会出现此错误，但我不明白为什么。 以下是我如何声明我的自定义对话框：

  dialogueGettingAllPatients = new DialogueGettingAllPatients(this);

以下是我调用对话框并尝试在任务完成后更新其UI的方式：

 dialogueGettingAllPatients.show();
        for (ZoneData zone : zonesSelected) {
         ...
                @Override
                public void onResponse(Call call, Response response) throws IOException {
                    String rsp = response.body().string();
                    try {
                        JSONArray jsonRsp = new JSONArray(rsp);
                        ...
                        dialogueGettingAllPatients.gettingDataSuccess = true;
                        dialogueGettingAllPatients.updateUI();
                    } catch (JSONException e) {
                        e.printStackTrace();
                    }
                }
            });
        }

以下是对话框的代码：

   public class DialogueGettingAllPatients extends Dialog implements android.view.View.OnClickListener {

    private ActivityMain activityMain;
    private ImageView success, failed;
    private Button ok;
    private GifImageView loadingLogo;
    public boolean gettingDataSuccess;


    public DialogueGettingAllPatients(Activity a) {
        super(a);
        this.activityMain = (ActivityMain) a;
    }

    public void updateUI(){
        if(gettingDataSuccess){
            loadingLogo.setVisibility(View.GONE);
            ok.setVisibility(View.VISIBLE);
            success.setVisibility(View.VISIBLE);
        } else {
            ok.setVisibility(View.VISIBLE);
            failed.setVisibility(View.GONE);
        }
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.dialogue_writting_tag);
        ok = (Button) findViewById(R.id.btn_ok);
        success = (ImageView) findViewById(R.id.imageValid);
        failed = (ImageView) findViewById(R.id.imageFailed);
        loadingLogo = (GifImageView) findViewById(R.id.loadingLogo);

        ok.setOnClickListener(this);
    }

    @Override
    public void onClick(View v) {
        switch (v.getId()) {
            case R.id.btn_ok:
                dismiss();
                break;
            default:
                break;
        }
    }
}
