Lottie动画多动图切换遇到的坑

问题原因是多动图json文件切换动图效果变成静态图。

布局：

Dialog:

public class PermissionLoadingDialog extends Dialog implements DialogInterface.OnDismissListener {

    private Context mContext;
    private LottieAnimationView lottieView;
    private TextView tvId;
    private String json = "";

    public PermissionLoadingDialog(@NonNull Context context, int themeResId) {
        super(context, themeResId);
        this.mContext = context;
    }

    public static boolean isMobileConnected(Context context) {
        if (context != null) {
            ConnectivityManager mConnectivityManager = (ConnectivityManager) context
                    .getSystemService(Context.CONNECTIVITY_SERVICE);
            NetworkInfo mMobileNetworkInfo = mConnectivityManager
                    .getNetworkInfo(ConnectivityManager.TYPE_MOBILE);
            if (mMobileNetworkInfo != null) {
                return mMobileNetworkInfo.isAvailable();
            }
        }
        return false;
    }

    public void test(String id) {
        if (isMobileConnected(mContext)) {
            tvId.setText(id + "/5");
        } else {
            tvId.setText(id + "/4");
        }
        if (lottieView.isAnimating()) {
            lottieView.cancelAnimation();
        }
        if (id.equals("1")) {
            json = "wifi.json";
        }
        if (id.equals("2")) {
            if (isMobileConnected(mContext)) {

            } else {

            }
        }

            }
        }

                json = "gps.json";
            } else {
                json = "battery.json";
            }
        }
        if (isMobileConnected(mContext)) {
            if (id.equals("5")) {
                json = "battery.json";
            }
        }
        LottieComposition.Factory.fromAssetFileName(mContext, json, composition -> {
            lottieView.setComposition(composition);
            lottieView.setAnimation(json);
            lottieView.playAnimation();
        });
    }

    @Override

        super.onCreate(savedInstanceState);
        getWindow().setDimAmount(0.2f);
        View inflate = LayoutInflater.from(mContext).inflate(R.layout.dialog_permission_loading_anim, null);
        setContentView(inflate);
        lottieView = inflate.findViewById(R.id.lottieAnimView);
        tvId = inflate.findViewById(R.id.tv_id);
        setOnDismissListener(this);
        this.setCanceledOnTouchOutside(false);
        this.setCancelable(false);
    }

    @Override
    public void show() {
        super.show();
        lottieView.playAnimation();
    }

    @Override
    public void onDismiss(DialogInterface dialog) {
        if (lottieView != null) {
            lottieView.pauseAnimation();
        }
